  • At a time when water, electricity and the Internet are readily available, nearly 1.2 billion people around the world live in rural areas without access to water and electricity. Solar systems, a clean energy source, were a good help, but the cost was so high that farmers living on dollars a day could not afford it. They had to buy fuel such as kerosene, which was unsafe and expensive. Lesley Marincola, master of mechanical engineering, designed a "Pay-As-You-Go" for these off-grid farmers, and distributors selling solar equipment, allowing farmers to share the prepaid costs. Finally, they can afford clean energy. Lesley graduated from Stanford University with a bachelor's degree in product design and continued to study for a master's degree in mechanical engineering at Stanford. She said that in engineering classes, 80 % of her classmates are men. She is even less likely to see women in investment opportunities in the future. Wearing the label of a female engineer, Lesley has emerged in many major companies, including the Amazon Kindle, until she met a Kenyan woman Rose. Rose is a smart Kenyan woman who lives in a rural area that is out of the water supply system. She works during the day and sells solar lights near the village at night. According to statistics, 1.2 billion people in the world are in a state of disconnection with the outside world. Some villagers occasionally have power generation equipment due to donations from non-profit organizations or charities. Therefore, many households still use kerosene as fuel. However, kerosene is dangerous and releases toxic gases. The price is not cheap. The average household often uses nearly 20 % of its income to buy fuel lighting. Solar energy is a clean energy source. It should help these households that are separated from the hydropower supply system to provide stable electricity, safe and low-cost, but Rose can only sell a few solar lights per month, and Lesley is troubled by poor sales, but she later found that Many farmers earn only $1 or $2 a day, and solar systems are often expensive to install. Poor farmers do not have enough funds or savings habits to buy clean energy systems such as solar energy at once. They also do not have bank accounts and can not borrow money. To maintain household lighting or other energy use, only a portion of monthly income can be spent on fuel, leading to a vicious cycle of poverty. Leslie was wondering how she could completely reform the power industry so that poor isolated farmers could get the clean energy they needed. Lesley came up with a win-win solution. She established Angaza in 2012, developed an electronic system platform, and cooperated with solar lamp manufacturers and distributors to modify their products. Combine these clean energy products with a "Pay-As-You-Go" system. This pay-as-you-go system is for distributors to increase consumer energy use by allowing these poor farmers to pay for off-grid solar systems through affordable instalments. According to the Global Off-Light Association, the power energy market in poor areas can be as high as 50 billion U.S. dollars per year, which is a blank market for distributors. Distributors can also systematically collect user information through Angaza's platform. In addition to allowing them to remotely diagnose and solve problems, prevent product failures, and do not need to arrange technicians to travel to rural families to incur high costs, but also allow them to get more information. To expand the business. It is even more convenient for users. They only have to pay a small down payment of about US$ 1-5, purchase solar lights through Angaza's local distributors, and obtain charging interfaces and solar panels; Just like the mobile phone call fee, the lighting time of the solar lamp is proportional to the cost paid by the user. Once the account balance is used up, the new fee will be paid by telephone. If no new fee is paid, the solar system will stop providing electricity; In addition, users need to pay the remaining cost of buying solar lights within 12 months, approximately US$ 1-2 per month. They no longer need to worry about unsafe kerosene, releasing toxic gases, and save money on fuel to keep their children in school. Angaza's system can not only be used for solar lights, but also cooperate with solar pumps, stoves, etc. to bring clean energy to the poor, change their habit of using kerosene, and reduce pollution of the environment and health hazards. At the same time, it has brought huge business opportunities for new energy equipment distributors in Kenya, Tanzania, Uganda, Malawi, Zambia, South Africa, India and Pakistan. "By allowing these off-line people to pay in small instalments, they can eventually afford these products, and distributors also benefit from monitoring data and monitoring customer payments. Over the past two years, 2 million people have switched from fuels such as kerosene to clean energy, such as solar energy, and hope to connect solar systems to 100 million poor people over the next five years, said Peter Thuo, Angaza's customer manager. So far, Angaza has benefited more than 500,000 households, saving them more than $50 million, Lesley said. "This is to give anyone access to the world, no matter where you are or where you are. "
  • European PV industry rises European demand for photovoltaic will be the strongest year since 2012 and is expected to reach 18 gigawatts, against the backdrop of an increasing number of business agreements. IHS believes that the more attractive cost competitiveness is the main driver of the European solar energy renaissance. Utility scale markets in Europe will be the biggest winners, accounting for 48 per cent of installations, up from 33 per cent last year. "The increase is due to tenders from Germany, France, the Netherlands and Spain, which will increase the size of new utilities in Europe by 62 per cent this year," the IHS report said. Almost a quarter of the new photovoltaic capacity will come from private purchase agreements signed directly with large electricity consumers or energy traders. The main markets for private power purchase agreements are Spain, Portugal and Italy. Renovation and upgrading European aging photovoltaic facilities will be retrofitted, upgraded and resupplied in 2019. According to IHS Markit, about 40 gigawatts of capacity plants have been in service for more than six years. Although old-fashioned photovoltaic facilities benefit from generous incentives, aging technology and component defects will affect production capacity. Equipment manufacturers seeking new sales channels see opportunities, especially in Germany, Italy, and Hefaguo, Spain. China will continue to promote global market dynamics In the past eight years, China has experienced unprecedented growth in photovoltaic power generation, with 175 gigawatts installed. The National feed-in tariff policy stimulated the domestic market and the country quickly strengthened its manufacturing base. So far, China's national development and reform commission has begun pushing photovoltaic power to grid parity, but unsubsidized projects will generate little demand this year, according to IHS analysts. Still, analysts predict China will stabilize at 40 to 50 gigawatts over the next four years. The IHS also said China would continue to support this estimate by providing a framework that reflects its climate-sensitive agenda and protects its manufacturing base. "Any major deviation by China from this path will have a significant impact on the global outlook," analysts explained. " Large energy storage space for public utilities The IHS said it would see the first meaningful installation of utility scale energy reserves juxtaposed with solar power plants this year. Most of the development will take place in North America, with a forecast of 500 megawatt-hours. American market growth will be boosted by federal investment tax credits. Last year, it was decided that the tax plan could also be applied to storage systems that juxtaposed solar energy with utility sizes. The IHS report notes that "projects to increase the size of utility photovoltaic systems for batteries in the United States have grown to more than 6 gigawatts," but analysts caution that many projects are speculative. However, they expect to build 2 gigawatts of energy storage over the next five years. With the exception of the United States, South Korea is another high-growth market for large energy storage this year. Inverter Market Competition Inverter prices have fallen 61 % in the past five years, putting enormous pressure on manufacturers 'profits and revenues. As a result, many suppliers have sought to diversify their product mix by providing engineering, procurement and construction services, as well as operations and maintenance. Analysts say the trend will continue. To avoid the commercialization of inverter products, suppliers must make rapid use of artificial intelligence, machine learning, Internet of Things applications and other new technologies. Charging of electric vehicles is expected to grow at a high rate over the next decade. Module efficiency competition is heating up The efficiency of solar modules has increased by 25 % over the past decade, and high-performance technologies such as single-crystal batteries are becoming mainstream. More efficient PERC batteries could account for half of global production this year, up from 14 per cent in 2016. "The possibility of using p-type PERC batteries for mass production of 400W modules in 2019 is being discussed," IHS said. "Longji, Jingke, Canadian Solar and other first-line brands have announced products that will reach 400W. However, the two-sided module may need to wait until 2020 or later to achieve a commercial breakthrough. Before that, the pilot will provide more data for investors considering technology, according to IHS Markit. Full digitization of energy systems About 30,000 new Internet of Things photovoltaic inverters are shipped every day this year, reaching about 11 million in 12 months. The industry will focus this year on how to generate value from the data they will provide, the IHS said. Operations and management may be the first application area of the development. For example, ABB, Schneider Electric and Siemens have provided a full range of industrial Internet of Things platforms. In addition, there may be developments this year in the measurement, monitoring and operation of more decentralized residential and grid scale solar power plants. Even the combination of accumulated data may lead to utility management packages. "For example, combining customer measurement data, solar inverter output and weather information can enable utilities or grid operators to calculate and cover energy needs and better manage the grid. "
  • As one of China's top ten targeted poverty alleviation projects, since the pilot work began in 2014, remarkable progress has been made in the past five years, and the goal of increasing the income of poor people and effectively protecting the ecological environment has been steadily achieved. At the same time, there are also a series of problems such as poor quality, low stability, and unreliable income. In order to ensure the stability of the income of the photovoltaic poverty alleviation power station, at the "2019 China PV Poverty Reduction Symposium for a New Era" held on March 9, the person in charge of a poverty alleviation agency said: "By the end of 2018, the state has issued a photovoltaic poverty alleviation power station target of more than 15GW. However, there are 5GW indicators that have failed to pass the production review for various reasons. " Due to a series of problems in the photovoltaics power station, the Poverty Reduction Office of the State Council has focused its attention on the quality of photovoltaics in 2019. In an interview, the head of the aid-the-poor agency said: "This year, the country will conduct the first interview work on the photovoltaics poverty alleviation power station. The relevant personnel of the project that has been declared successful but has not been strictly implemented as required will be interviewed. " Worry of Photovoltaics Poverty Alleviation Power Station "On the one hand, we are struggling to compete for the targets of photovoltaic poverty alleviation projects in various parts of the country. Only 320 areas should have met the conditions for applying for photovoltaic poverty alleviation power stations, but they have welcomed more than twice as many applicants. On the other hand, they have seized the areas where photovoltaic poverty alleviation projects have been carried out. One-third of them can't get through production properly. The poor quality, low stability and unguaranteed yield of power stations have seriously affected the poverty eradication effectiveness of photovoltaic project sites. " According to the Beijing Jianheng Certification Center, after a long period of time, various forms of power station testing and evaluation have been carried out in 10 provinces and 45 counties across the country, and nearly 400 village-level and village-level joint power stations and 40 centralized pro-poor power stations have been put into operation. It is found that the problems of poor equipment quality and low reliability seriously affect the expected revenue of photovoltaics power stations. Jizhenshuang, deputy director of the Beijing Jianheng Certification Center, pointed out at the meeting: "Overall, PV poverty alleviation has achieved remarkable results. Power stations have been built and shipped. The performance level of most power stations is within acceptable limits, and the expected income can basically be achieved.; A small number of power stations have low efficiency levels. A small number of power stations can not meet the requirements of economic operation, and even some power stations should be put out of operation. This should attract sufficient attention. It is understood that the reason why the photovoltaics poverty alleviation power station has the above problems is mainly because some companies use the photovoltaics poverty alleviation power station as a "gold mine", and the equipment, products, and transportation and maintenance used have not met certain standards. Even some photovoltaic power stations use photovoltaic components that have been eliminated, and the later transportation is unmanned, making the power station an "orphan" power station. Based on the current situation of the photovoltaic poverty alleviation power station, Deputy Director Jizhenshuang suggested: "In selecting the key equipment of the photovoltaic poverty alleviation power station, especially components and inverters, we should try our best to choose the first-line brand companies that meet the standards of the front-runners, have good quality credibility, and have strong comprehensive strength. Products, In this way, the quality of the power station, the stability of the system and the effectiveness of the revenue can be guaranteed. " The "leader program" standard is inevitable Due to a series of problems in the photovoltaics power station, the Poverty Reduction Office of the State Council has focused its attention on the quality of photovoltaics in 2019. In an interview, the head of the aid-the-poor agency said: "This year, the country will conduct the first interview work on the photovoltaics poverty alleviation power station. The relevant personnel of the project that has been declared successful but has not been strictly implemented as required will be interviewed. " A few days ago, Liuyongfu, director of the Poverty Alleviation Office of the State Council, also said in an interview with the media that China's poverty alleviation work has entered a critical period. This year, more than 10 million poor people will be reduced. We must severely crack down on fraud in the area of poverty alleviation. Therefore, the state attaches great importance to the problem of fraud in the field of poverty alleviation. Including photovoltaics, the state is bound to conduct centralized evaluation and management of all poverty alleviation projects this year. Those responsible for photovoltaics power stations that are of low quality, inefficient, and have no guarantee of income will be blamed. In order to monitor the quality of photovoltaic poverty alleviation power stations, the Poverty Reduction Office of the State Council will carry out real-time monitoring of photovoltaic poverty alleviation power stations in 2019. The power generation of photovoltaic poverty alleviation power stations will be reported in real time, and it will be clear whether the efficiency of photovoltaic poverty alleviation power stations will meet the standards. In addition, the Poverty Reduction Office of the State Council will also strictly focus on the quality work of photovoltaic poverty alleviation power stations and, in coordination with relevant departments, will issue the "Measures for the Management of Photovolt Power Stations." With the above measures, inefficient photovoltaic poverty alleviation power stations will have nowhere to hide. High-quality, high-efficiency and high-yield photovoltaic poverty alleviation power stations that meet the standards of "front-runners" will become the mainstream of photovoltaic poverty alleviation. The standards of "leader's plan" should be carried out throughout the construction of power stations The PV poverty alleviation station wants to maintain the same standards as the front-runners, not only in the selection of components and inverters, but also in the design and construction of good design construction units. Jizhenshuang emphasized: "The improper selection of sites and the unreasonable array design have led to the low performance of photovoltaic power stations. The reporter learned that some power stations did not consider Geological conditions when they were located. After the completion of the poverty alleviation power station, the power station was shut down due to floods, landslides and other reasons. There are also some power stations that have caused various failures in power stations after the investment and transportation of pro-poor power stations due to the design and construction of reduced materials and the failure of freezing factors. Even some power stations did not use the corresponding cables and overload protection devices as required, resulting in fire and other safety accidents in the power station. Such events are numerous. The construction of photovoltaics poverty alleviation power station should let the standards of the front-runners be implemented from beginning to end. The Information Industry Electronics 11th Design and Research Institute Co., Ltd.. General Manager of Science and Technology Engineering Co., Ltd. and Huamingshi, Director of Beiling Power Station, introduced at the symposium: "We have built a 40 MW ground photovoltaic power project in Gongyi, and the project will be connected in 2016. The network has so far accumulated nearly 100 million degrees of power generation. Now our gongyi 40 megawatt photovoltaic power station has become a local business card. " The reason for this achievement is that Huamingshi believes that eleven technologies have been fully prepared at the beginning of the design and construction. He analyzed: "First, according to the cooperation of land planning plans and local government planning departments, the scope of unused land is initially determined, and the best area is 1-2 times the actual area of use, and the land and forestry parts are coordinated; The second is to see whether there are 35 kV and field substations around the site area. If the power station capacity is below 30 MW, you can choose 35 kV lines. If 35 MW or more, Deze chooses 10 kV lines; Third, fully assess the terrain and try to choose the direction toward the South. If there is no positive South, you can choose to set up photovoltaic panels in the Southeast or Southwest direction; Fourth, pay attention to removing graves and gutters within the site area to prevent landslides and subsidence due to loose soil; The fifth is whether there are traffic conditions around the survey, whether it can meet the entry and exit of large vehicles, whether there are overpasses and culverts on the main traffic routes, and whether it can meet the requirements for the entry of large equipment in the later period; The sixth is to carry out preliminary ground survey, understand the geographical conditions, and on this basis plan the construction plan of the mountain photovolt power station bracket. " With such a detailed preliminary preparation is not enough, it is also necessary to comprehensively consider the terrain analysis and sunshine shadow analysis of mountain power stations; Select suitable support form for construction; Select the suitable design of the power line; Give full attention to the design of the drainage system in the formation area; Proper planning and construction of main roads and patrol roads in the array area of power stations. The 11th Science and Technology is to adhere to the design and construction of photovoltaic power stations based on the standards of front-runners. Each step takes full account of the use of power stations in the next 25 years or more as a starting point, and comprehensively builds high-quality photovoltaic power stations., won the praise of the industry. 30 % increase in poverty alleviation with "Lead Runner Plan" It is reported that the "National PV Runner Program" was initiated by the National Energy Administration and uses the most advanced technologies and core equipment of photovoltaic power stations, such as components and inverters, to build photovoltaic power generation demonstration bases and new technology application demonstration projects. Starting from the first batch of PV leaders 'plans launched in Datong, Shanxi Province, China's PV industry has developed rapidly, and the requirements for the core equipment of PV power stations, such as components and inverters, have been constantly increasing. It is always the most advanced technology and product in the industry. Poverty alleviation by the standards of the front-runners is a clear request in the "Measures for the Management of Photovoltaics Poverty Alleviation Power Stations." Longjileye, assistant chairman of Wangyingge, said at the symposium: "Only when the quality of the photovoltaics poverty alleviation power station is guaranteed, the safety is guaranteed, and the power generation is guaranteed, the issue of poverty eradication effectiveness is discussed. The state hopes that the benefits of photovoltaic power stations will be long-term and sustainable. Longji actively responded to the call of the national policy to use the products of the front-runners to do photovoltaic poverty alleviation projects. The photovoltaic poverty alleviation project can use Longji's half piece of double-sided product Hi-MO3, which has higher power than ordinary components and double-sided power generation. Poor households can increase their income by about 30 %. " Qinxiao, deputy director of the solar energy Department of the General Institute of Hydropower Planning and Design, summed up the experience of photovoltaic poverty alleviation over the years and said that the country attaches great importance to the development of photovoltaic poverty alleviation. The photovoltaics poverty alleviation has also shifted from the initial exploration to a new stage of quality and efficiency improvement. Judging from the results of the test of the photovoltaic poverty alleviation power station that has been built so far, the photovoltaic poverty alleviation project that adopts the standards of the front-runners has higher power generation, which brings more benefits to the people and will be more sustainable. The reporter learned that by 2020, the government will build photovoltaic poverty alleviation power stations in about 50,000 state-level poor villages with good lighting conditions, and use the entire village to advance, thus guaranteeing 2.8 million non-working poor households. Each year, each household will increase its income by more than 3,000 yuan. At present, a total of 13.63 million kilowatts of photovoltaics power stations have been built to help 2.24 million poor households. The construction of photovoltaics power stations will reach their final peak this year and next, and only the core equipment that meets the standards of the front-runners will be selected. For example, components, inverters, etc., and choose to use the leader as the standard for the design and construction of power stations, in order to achieve the expected poverty alleviation effect, can withstand the test of time, can make photovoltaic poverty alleviation become the most concentrated in the precision industry poverty alleviation.
  • 14 Provinces Have Excellent PV Market Potential According to the regulations of the National Energy Administration, the results of photovoltaic environmental monitoring and evaluation are an important basis for guiding the orderly development of various regions. Among them, the area where the evaluation result is red is released in principle. Orange District can arrange an annual planning and guidance scale of up to 50 % on the premise that relevant parties propose measures to protect the market environment. The National Energy Bureau of Green Area will guarantee the scale of its photovoltaic power station development according to the plan and provide appropriate support as appropriate. Local governments and enterprises can arrange investment and construction in an orderly manner. Our statistics for the three years from 2016 to 2018 show that the three northeastern provinces, Jiangsu, Zhejiang, Anhui, Jiangxi, Henan, Hebei, Hunan, Guangdong, Guangxi, Guizhou and other regions have performed steadily and are basically evaluated as green areas. This means that the PV market in these 14 provinces has low risk and high potential, and has long-term and stable development prospects, and is suitable for enterprises to make investment choices. In addition to these 14 provinces, this year's Inner Mongolia Mengdong Sidi Class II Resource Area, Shaanxi Yulin, Yan 'an District, Class III Resource Area, and Shanxi Class III Resource Area have also successfully entered the green camp. According to the statistics of market installed capacity in the first three quarters of 2018, 71 % of the new market installed capacity in the country comes from green areas, and the hot market situation is evident. In the context of this year's PV industry's promotion of affordable Internet access, these evaluation results will be the first to benefit from the green areas. Combined with regional planning, government support and other convenient conditions, it is expected that at least 15 GW of new installed capacity will be concentrated in these areas. outbreak. Red Lights in the Three Northwestern Provinces In the latest statistical evaluation results, Gansu and Xinjiang have been listed as red areas for three consecutive years, and the situation of photovoltaic power generation market is worrying. The Tibetan region was orange in 2016 and 2017, and it was also evaluated as red in 2018. This means that these three places will not, in principle, release the annual new construction scale this year. In addition, according to the previous regulations of the Energy Bureau in the promotion of parity access policy, photovoltaic power generation early warning evaluations are red areas, and in principle no new local affordable access projects and low-cost access projects will be arranged. This means that in Xinjiang, Gansu and Tibet, PV parity will lag behind, and even in the short term, there will be no new PV projects for local consumption. In fact, the main problem in these three regions is photovoltaics. In response to this problem, the country has also passed the "Clean Energy Absorption Action Plan," which stipulated that by 2020, the disposal rate in Gansu, Xinjiang and other places should be limited to 10 %. In the next one to two years, the advantages of the photovoltaic market are also expected to re-emerge as the disposal of light in these three regions eases. The remaining orange areas can select approved(filed) projects with better resource conditions to continue to work on affordable and low-cost Internet access. Comparing the results of the monitoring and evaluation of the PV power generation market from 2016 to 2018, we can see that the domestic PV market environment has generally improved, which is conducive to the long-term healthy development of PV.
  • This year, major institutional innovations will be made in the management of photovoltaic power generation in China. On the afternoon of February 18, the New Energy Department of the National Energy Administration convened a symposium for relevant companies to solicit corporate opinions on the management of photovoltaic power generation in 2019. "The Ministry of Finance determines the scale of subsidies, the upper limit of subsidies set by the NDRC, the competition rules set by the Energy Bureau, the intensity of enterprises 'subsidies, and the scale of market construction. Industry experts have summed up the key points of the draft consultation. In addition to the business representative seminar on the afternoon of February 18, the Department of New Energy of the Department of Energy will also organize a symposium for experts and associations on February 19. This also means that the draft opinion is only a discussion draft, and more details will be implemented in the future. There is still room for adjustment. Decrease subsidies, market expansion At the end of 2018, China's photovoltaic power generation ranks first in the world, and photovoltaic power generation has changed from a high-speed growth stage to a high-quality development stage. In order to further improve the management of photovoltaic power generation construction, the National Energy Administration stated at a press conference held earlier that according to the actual development of the industry, photovoltaic development in 2019 will be divided into photovoltaic power projects that do not require state subsidies and photovoltaic power projects that require state subsidies.. For photovoltaic power generation projects that do not require state subsidies, local governments shall organize the construction of such projects on the premise that they meet the management requirements of planning, monitoring and evaluation of the market environment, and implement the conditions such as access to the network. Specifically in accordance with the provisions of the "Circular on Actively Promoting the Work of Unsubsidized Affordable Internet Access for Wind Power and Photovoltaics". For photovoltaic power generation projects that require state subsidies, except for projects that are specially supported by state policies, in principle, construction projects and subsidies should be determined by market-oriented competition. The discussion paper, which was of great interest, divided the projects that needed subsidies into five categories: poverty reduction projects; Household photovoltaic; Ordinary photovoltaic power stations(ground power stations); Industrial and commercial distributed photovoltaic and leading players, ultra-high pressure channel supporting and other special projects. In addition to poverty alleviation, household use and approved special projects, the discussion paper pointed out that distributed and terrestrial power stations all use competitive methods to obtain subsidy targets. The change in management thinking is also reflected in the fact that the scale of the project is no longer allocated to various places in a "netting" manner, and the development of better resources is given priority. "The significance of the upper limit of the price set by the NDRC is to set the price of electricity for non-competitive projects such as household photovoltaic and poverty alleviation. The Energy Bureau formulates the rules for bidding, and enterprises declare the price of electricity according to their own conditions, which is equivalent to the strength of subsidies to be determined by the enterprises themselves. So the size of the market is determined by the market, which means that the identity of the Energy Agency has also changed dramatically, from the management of resource distribution to auction houses. "Pengpeng, Secretary General of the New Energy Power Investment Alliance, said. According to market rumors, the scale of photovoltaic new subsidies in 2019 is RMB 3 billion, so the higher the power subsidy, the smaller the market size. The willingness on the part of companies is that the size of the market is willing to transfer the intensity of subsidies before the intensity of subsidies, in exchange for greater market size. "The shift in role is the general trend, because according to the current situation in the market, if there is no alternative source of funding for renewable energy subsidies, and at the same time it is hoped that there will be a larger market size to support the new market, and then drive the subsequent manufacturing industry., Therefore, there is a need to reduce the intensity of subsidies and come up with new project allocation methods. The new energy power investment alliance believes this will make it more difficult for energy bureaus at all levels to manage projects. How to bid? Specifically, according to the division of the resource area where the project is located, the price of the bid will be rated as the decrease in the price of the bid price(with the smallest unit as the minimum unit) compared to the maximum bid price of each resource area, and the large reduction will be ranked first to determine the items included in the subsidy scope. Until the total amount of subsidy for the selected project reaches the total amount of subsidy for the current new project set by the State. The core of the existing bidding rules is to control the total amount of subsidies through bidding so that it can support as many projects as possible. In terms of refinement, provinces will calculate the total amount of subsidies for annual projects based on the expected annual power generation hours and installed capacity after ranking according to the level of the subsidy price compared to the level of the competitive price. The competent national department then puts the projects summarized by each province into the summary table, and ranks the price of the combined tariff declaration as compared with the price of the bid upper limit, until the total amount of subsidies for the selected projects reaches the total amount of subsidies for the new project in the year determined by the state. After "2018," 5.31 "After the network, projects that do not require subsidies have the most advantages. For these companies, subsequent subsidies are additional benefits. Mr Pengpeng said: "Further discussion is needed on how to participate in completed projects." " It should be noted that the discussion on modalities and methods of bidding should also take into account relevant supporting documents, such as the electricity price policy document, the document on the clear allocation of subsidies, and the document on the market environment monitoring mechanism. The specific implementation of the bidding involves some of the provisions in the above documents that are questionable. "If the national policy can be released by the beginning of March, considering that the provinces still need to conduct project statistics for a certain period of time, it is already a more optimistic estimate for the development companies in the second quarter. If we want to achieve the network by the end of the year, There are only two quarters of the construction cycle, which is more stressful for state-owned enterprises. "Pengpeng said. According to the discussion paper, when reporting, each project is required to report a clear construction period, that is, the production season. Projects that enter the scope of state subsidies should be completed and connected before the end of the expected production quarter of the declaration. If they are not completed by the end of the deadline, the price of electricity and subsidies should be reduced by the same extent as the National tariff policy. If it is not completed within two quarters after the filing quarter, it is considered as an automatic waiver, disqualifying the project subsidy, and affecting the market environment monitoring and evaluation in the area, which ultimately affects the owner's next year's project declaration. Regarding the new market in 2019, Anxin New pointed out that in the first quarter of this year, everyone has a high degree of enthusiasm for photovoltaic. This year's overseas business has grown rapidly. First-and second-tier companies have already signed up for orders in the first half of the year, and some companies are also signing orders for the third and fourth quarters. These orders also come mainly from overseas markets. After "May 31", overseas markets reflected the demand for parity. "The efforts in the Chinese industrial chain have brought many foreign markets to a state of parity. At present, the amount in Europe has grown rapidly. From this perspective, many enterprises will have a good performance in this round of cycle, industrial chain prices have also recovered. "Anxin new chief Dengkangyong said.
  • On February 14, 2019, the Guizhou Provincial Development and Reform Commission announced the "2019 Guizhou Province Major Projects and Key Projects List and Promotion Plan". In 2019, 2,738 major projects and key projects were arranged, with a total investment of 4,446.6 billion yuan. The investment is 720.4 billion yuan. It is understood that the list covers power projects in various fields such as hydropower, wind power, photovoltaic power generation, transmission and distribution.
  • The photovoltaic industry is entering a new round of industrial integration. The policy is iteratively accelerated, low-price competition is rampant, and the industry's production capacity is over-represented, and the industry's oligarchy tends to be obvious. The phrase [a bright future" cannot sum up the real situation of the development of the entire industry. Just like the game in "Animal Manor", the strong devours the weak, the fist is big and the fist is small, and the business competition is extremely cruel. The analysis believes that in the next few years, the following 12 PV companies are likely to be eliminated in the new round of industrial integration and competition. The first one: long-term cash flow is tight, stocks are high, and companies with serious triangular debts Not only small enterprises, according to the analysis of the earnings of some listed companies, some medium-sized and large-scale enterprises also have very tight cash flow, and there are also some pressures on inventory. Some enterprises have high accounts receivable and management costs increase significantly. If there are no effective strategies and channels to solve the above problems and pressures in the long run, some enterprises will lose the ability to continue to operate, and eventually suddenly [broken" or even close down in the violent fluctuations of industrial policies or markets. Second: companies without core technology, no innovation and motivation Saying goodbye to the era of "scale advantage", the photovoltaic industry is developing with high quality and efficiency, reducing costs with technological innovation, and finally achieving parity online. You can't stop this trend. In this industry, once I have imitated the drawings, or gave people a job, I can make money, but that era is gradually drifting away. Even if you rely on the big tree, if you don't have core technology, you don't have the ability to innovate, and sooner or later you will be eliminated. The third type: photovoltaic enterprises with extensive management of enterprises and incapable of reducing costs in management and operation This year's PV front-runners bid for several times to issue the first round of warnings to enterprises. Next year's "super leader" is expected to bring more pressure to some companies. Enterprises should not only be technologically innovative, but also continually optimize management and operations to reduce overall costs to adapt to the era of increasingly low prices. For some medium-sized and large-scale PV companies, it is also necessary to establish a modern enterprise system with the best domestic and foreign companies as the benchmark to achieve sustainable growth. The fourth type: medium-sized photovoltaic enterprises with the top leaders of the enterprise [knowing people without knowing themselves" Some medium-sized PV companies have been established for some years, and they have also established a certain status in the market, and the leaders of the company can be regarded as a success, and it is time to "sit a break." After they have become famous, they may look at the head of the people and look dizzy. Therefore, there is no new and clear strategic plan: what to insist on, what to improve, how to innovate, how to stick to it, and how to face new competition. Fifth: companies that rely too heavily on a regional market If you rely too much on a country or regional market, once the policy or market changes, the company's survival may immediately fall into the realm of life and death. For example, Shanghai has a grid-connected inverter manufacturer, 90% of which are sold to the UK market. Today, the scenery of the UK market is no longer the fate of this manufacturer. This is just a manufacturer of inverter electrical appliances, and there are quite a few component factories. This 1-2 years depends on the British market, and the strength is maintained. The UK market suddenly changed, and some small and medium-sized PV companies in China soon faced the problem of bankruptcy. Sixth: small and medium-sized enterprises that are involved in photovoltaics but are accustomed to twisting As the industry recovers, other new capital entering the photovoltaic industry is also increasing. Especially in the wake of entrepreneurial trends and the promotion of related policies such as [Photovoltaic+", there are more and more cross-border companies emerging in the upstream and downstream of the PV industry chain. They cover all aspects of the upstream and downstream of the photovoltaic industry chain. Some of them are born out of the photovoltaic industry, and some may come from IT, big power, and even the industry where "the gossip can't beat". It is completely cross-border. For such enterprises, the most taboo should be [empiricalism": different time, different markets, different industries, facing different employees or consumers, if you want to use the past feelings to do market, do channels, engage in contacts, It may not work in the photovoltaic industry. They are likely to be blocked in the fierce market competition, and there will be chasing troops in the future. In the end, they will be [suppressed to death". Seventh: companies that rely on one or two big customers to discuss life The term "big customer" always makes the eyes of the marketers shine. However, large customers sometimes face financial constraints, construction suspension, and planned changes. Large customers can generally rely on a while, but they can't rely on the world. Under the increasingly standardized industry, but the competition is becoming increasingly fierce, many big customers may not dare to continue to arbitrarily sprinkle money. What should I do in the future? Companies that rely on one or two big customers are risky. Unless you are relying on a large customer at the first level. If you rely on the second, third and fourth level customers, high risk! Others are new companies that were established after the [single flight" of the original large companies. They may also rely on a fixed [big customer" or a single channel to survive, but the risk is also very high,big. The eighth type: some enterprises that want to solve problems by [funding" and [crowdfunding" According to the observation of entrepreneur Feng Lun, there are mainly three ways for private enterprises to allocate capital resources. One is to allocate resources by power levers, and the other is to allocate resources by means of market. Another is to raise funds by geography, kinship and blood relationship. Past historical evidence proves that most of the people who actually die in fundraising are grassroots private entrepreneurs. For some PV companies, if you don't have the privilege of configuring resources and the experience, knowledge and ability of the market to allocate resources, you have to take the private fund-raising route. When the law is too strict, it is easy to get out of the situation. Sudden death or accidental injury, so I went to the other side. The ninth: obsessed with political and business relations, and the "tiger" officials are inextricably entrepreneurs or bosses In China, officials of all sizes can be called politicians. Large and small bosses are also called entrepreneurs. The relationship between politics and business has evolved into a relationship between leaders and bosses. The development of photovoltaic enterprises is inseparable from the support of government departments and officials at all levels. However, things have two sides, and the investment in large-scale PV projects is huge, involving many bidding matters. Now the "anti-corruption storm" is still going on, and the tiger movement has not stopped. In the past few years, the energy industry has been [handled" by a large number of tigers. The so-called [pull up the radish and bring out the mud", even if it is a very good business of photovoltaic enterprises, once the incident occurs, the consequences are unimaginable. The heads of photovoltaic enterprises should pay attention to it. In the fierce market competition environment, we must pay attention to physical health and avoid entering the hospital. Second, we must handle the relationship between government and business, and put more emphasis on corporate governance and innovation, so as not to enter the court. The tenth: the "hacker" company, the shell company, the hit company With the completion of relevant regulatory policies and the maturity of the market, many [body companies" in the photovoltaic industry rely on contacts and [roads" to live a productive life and perhaps go to the end (at least reduce) . The goal of the current industrial policy is to go online at a low price, and companies with technology, cost and management advantages can get more market share. In the past, the situation of [bad money expelling good money" has been obviously reversed. In the past, relying on [making relationships" every day, companies that use unscrupulous means to engage in [roads" and defraud subsidies will be squeezed out of the market. The eleventh: a company that succumbs to strategic choices and owes too much money Some medium-sized and large-scale companies may have lived in the past few years, but they must avoid strategic investment mistakes. There have been many lessons from the case of dragging down enterprises due to investment mistakes. Another company that is the easiest to dump is a large company with large accounts, which have large companies and small companies. The economy is down, and cash is king. The overall economic situation is not good, and the photovoltaic enterprises that are first dumped must be enterprises with poor cash flow. At present, in order to ensure cash flow, the accounts receivable cycle between upstream and downstream enterprises is also constantly expanding. Once individual medium-sized and large enterprises fail, they may drag on more companies. The twelfth type: can not stand the vicious competition, see the photovoltaic "red dust", the initiative to leave the enterprise Although the photovoltaic industry is very attractive, the business here is not good. How much money does PV make? If the subsidy falls or the subsidy is cancelled? The low price competition in 2017 and 2018 has reached the point of [malicious" and even [unbearable" for some investors. Then there may be enterprises that [see through the red dust" (none be disillusioned with the mortal world)and leave the photovoltaic industry – I am not mixing here, I am going to engage in the Internet. Going to eco-agriculture, can't you do it? Making money is not necessarily less than this!
  • The use of solar energy by humans has long been popular, but the utilization of solar energy on the ground is not high, and it will be attenuated by the absorption and scattering of the atmosphere, as well as the effects of cloud rain, season, and day and night. At the same time, the energy density varies greatly and is very unstable. Solar energy in space is very abundant. Pang Zhihao, chief scientific communication expert for space exploration technology in the country, said that if a solar power station is built on a geosynchronous orbit about 36,000 kilometers, the sun's rays will not be weakened by the atmosphere, nor will it be affected by seasonal and day and night changes. 99% of the time can be Stable reception of solar radiation, its intensity is more than 6 times the ground. The fixed-point transmission of energy through the space to the ground provides an inexhaustible source of clean energy for humans. The core application goal of the development of space solar power plants is to provide large-scale commercial power supply to the ground. Pang Zhihao said that because of its wide coverage, it can supply power to remote areas, islands and disaster areas, and it can also be used flexibly for ground moving targets. At the same time, space solar power plants can power spacecraft in the [visible" range, freeing spacecraft from huge solar cell wings and greatly increasing power levels and control accuracy. It can also be used as a candidate for deep space exploration energy systems, and it can also be used for space fuel production and space processing manufacturing in the future to realize space industry development. In addition, space solar power plants can also clean up the "bad" caused by traditional energy. Pang Zhihao said that the use of petrochemical energy has caused global warming, and there have been frequent occurrences of typhoons and tornadoes. The transmission of the huge energy of the space solar power station to the area where the typhoon is located can change the temperature distribution of the typhoon and destroy its formation process. Facing multiple technical challenges Pang Zhihao introduced that the main working principle of space solar power station is: solar power generation device converts solar energy into electric energy; energy conversion device converts electric energy into microwave or laser, and transmits the beam to the ground by using transmitting device; ground receiving system receives space transmission The beam is converted into electrical energy into the grid by a conversion device. "At present, the technical principle has not been much problem." Pang Zhihao said that in recent years, solar power generation efficiency, microwave conversion efficiency and related aerospace technology have made great progress, laying the foundation for the next step of development. However, as a grand space system, space solar power plants have to be broken in many aspects of technology. For example, the world's largest spacecraft, the International Space Station, weighs more than 400 tons, while an industrial-scale space solar power station weighs thousands of tons. How to build? Some domestic experts suggested that the construction materials of the space solar power station should be launched into space, and a "space factory" would be established. The required components would be printed out by 3D printing technology and then assembled by space robots (14.820, 0.06, 0.41%). This is one of the current research directions. Long-term operational safety is also an important issue. Pang Zhihao said that the impact of long-term microwave radiation on ecology, atmosphere, and organisms needs further study. In addition, the construction of space solar power plants poses great challenges to new materials, high-efficiency energy conversion devices, super-large spacecraft structures and control technologies, and on-orbit assembly and maintenance technologies. China is expected to be built first Because of its weight and scale far surpassing existing space facilities, space solar power plants are known as the [Manhattan Project" in the space and energy sectors of the new era. Since 1968, relevant concepts have been proposed. The US government and enterprises have invested nearly 100 million US dollars and implemented a number of research and development plans; Japan has officially included it in the national space long-term plan; Russia, India, South Korea, and ESA are also carrying out relevant the study. In 2008, China incorporated the research and development of space solar power plants into the national preliminary research plan. In recent years, the platform has proposed non-concentrating, quadratic symmetrical concentrating, multi-rotating joints and spherical energy harvesting arrays, while wireless energy transmission. Significant progress has been made in key technologies. At present, China's research on space solar power plants has initially realized from "follow-and-run" to "and run", becoming an important force in promoting the development of space solar power plants internationally. Li Ming, director of the Science and Technology Committee of the China Academy of Aerospace Science and Technology Corporation, told reporters that if China can maintain and further increase research and development, China is expected to become the first country in the world to build a solar power station with practical value space. The reporter learned that China's first space solar power plant experimental base has recently started construction in Chongqing. It plans to build small and medium-scale stratospheric solar power stations and generate electricity from 2021 to 2025; after 2025, it will start work on large-scale space solar power station systems. Xi'an will build a ground verification platform for the space solar power plant system project, which will be used for system verification of the function and efficiency of the space solar power station. According to the recommendations of the relevant expert group, China is striving to complete the space ultra-high voltage power transmission and wireless energy transmission test verification in the next ten years, and realize the construction of the megawatt space solar power test station in 2030 and the construction of the Jiwa class before 2050. Medium and long-term goals for the capacity of commercial space solar power plants.
  • Despite major policy adjustments, last year's new PV installations exceeded market expectations. On January 28th, the National Energy Administration held a press conference in Beijing to release the operation of renewable energy grid-connected in 2018. By the end of 2018, the domestic installed capacity of renewable energy power generation reached 728 million kilowatts, a year-on-year increase of 12%, accounting for 38.3% of all power installed capacity, up 1.7 percentage points year-on-year. Among them, hydropower installed capacity of 352 million kilowatts, wind power installed capacity of 184 million kilowatts, photovoltaic power generation installed capacity of 174 million kilowatts, biomass power generation installed 17.81 million kilowatts, respectively, an increase of 2.5%, 12.4%, 34% and 20.7%. In 2018, the national renewable energy power generation was 1.87 trillion kWh, accounting for 26.7% of all power generation. Wind power and photovoltaics continue to [double down". In 2018, the national wind power abandonment wind power was 27.7 billion kWh, a year-on-year decrease of 33.89%. The national average wind curtailment rate was 7%, down 5 percentage points year-on-year; the national photovoltaic power generation abandoned photoelectricity decreased by 1.8 billion kWh, and the light rejection rate was 3%, down 2.8 percentage points year-on-year. In 2018, photovoltaic power generation installed capacity of 44.26 million kilowatts, second only to the new installed capacity in 2017, the second highest in history. Among them, centralized power plants and distributed photovoltaics added 23.3 million kilowatts and 20.96 million kilowatts respectively, accounting for 52.64% and 47.46% respectively. As of the end of December 2018, the country's photovoltaic power generation installed capacity reached 174 million kilowatts, ranking first in the world. Among them, the centralized power station is 124 million kilowatts, and the distributed photovoltaic is 50.61 million kilowatts. Li Chuangjun, deputy director of the New Energy and Renewable Energy Division, said that photovoltaic power generation has shifted from a high-speed growth phase to a high-quality development phase. In 2019, the National Energy Administration will promote the high-quality development of photovoltaic power generation as the main line, and maintain a reasonable development scale and development pace of the photovoltaic industry. According to the actual development of the industry, PV development will be divided into two major pieces of management in 2019: one is a photovoltaic power generation project that does not require state subsidies, and the other is a photovoltaic power generation project that requires state subsidies. "For photovoltaic power generation projects that do not require state subsidies, under the premise of meeting the management requirements such as planning and market environment monitoring and evaluation, and implementing conditions such as network access, the local self-organized construction." Li Chuangjun said. On January 9, the National Development and Reform Commission and the National Energy Administration jointly issued the "Notice on Actively Promoting Non-subsidized Internet Access for Wind Power and Photovoltaic Power Generation". The wind power and photovoltaic industries ushered in the first policy of sending price-level Internet access. The document stipulates that low-cost, low-cost Internet projects will not be subject to annual construction scale restrictions. This means that the industry has provided another incremental market space under the premise that the subsidy gap is expanding and the indicators are shrinking. However, the scope of the above projects does not apply to the whole country. According to the policy, wind power and photovoltaic power generation monitoring and early warning (evaluation) are green areas, which can be carried out on the basis of implementing the conditions for consumption; in the orange area, it is encouraged to select approved (recorded) projects with better resource conditions; red areas In addition to the low-cost Internet demonstration projects that have been arranged for construction and the unsubsidized projects that have been delivered through the inter-provincial trans-regional transmission channels, in principle, no new local low-cost, low-cost Internet projects will be arranged. According to the [Results of Environmental Monitoring and Evaluation of Photovoltaic Power Generation Market in the First Three Quarters of 2018" issued by the National Renewable Energy Information Management Center, the evaluation results are that the green provinces are Heilongjiang, Liaoning, Shanxi, Hebei, Jiangsu, Zhejiang, Anhui, Jiangxi, Henan, Hubei, Hunan, Guangdong, Guangxi, Guizhou. This means that only 14 provinces in the country can carry out photovoltaic parity and low-cost Internet projects on their own. In response to the above-mentioned affordable Internet policy, the National Energy Administration further added at the conference that [wind power, photovoltaic level-level Internet projects and low-cost Internet projects will be organized and implemented by provincial energy authorities. Enterprises can provide provincial energy to the provinces as required. The competent department declares a parity online project and does not need to report to the National Energy Administration." For the photovoltaic power generation projects that require state subsidies, the National Energy Administration said that in addition to the special support projects of the national policy, in principle, market-based competition should be adopted to determine construction projects and subsidy standards. Specific policies, the Energy Bureau is currently working with relevant departments to study and will be introduced as soon as possible.
  • Various solar products emerge in an endless stream, but they are always used in a small range. The environmental protection effect of sand-forming towers is long.Larger applications include solar water heaters, solar roof power generation systems, and more.However, limited to the reasons for complex installation and low utilization, the application is not extensive and the effect is not great.The importance of solar energy is self-evident.A foreign team hopes to enhance the use of solar energy by households. Therefore, it has made new improvements to solar power generation systems and designed Smartflower. Smartflower is simple, efficient and powerful. It is an integrated solar system. Compared with traditional rooftop power generation systems, Smartflower can greatly improve conversion efficiency and utilization, and fully meet the needs of household power supply.The traditional inverter can only convert the DC output of the solar panel into an AC output to supply power to the power supply. Smartflower uses the VICTRON top-level QUATTRO inverter, which can directly store the excess energy generated in the built-in lithium battery and use the battery for the family electrical power supply. That is, the excess electric energy converted by solar energy can be stored at the same time, and the average utilization rate of the conventional solar power generation system is increased to 60%. At the same time, the battery can be used as a backup power source. The built-in system quickly takes over the connected load in less than 20 milliseconds in the event of a grid failure, allowing the electronic device to continue to operate without interruption. Moreover, Smartflower produces 40% more electricity than traditional rooftop systems because it tracks the straight sun at an angle of 90° from morning to night, independent of changes in the angle of daylight reception, and always converts power at maximum efficiency.This is depend on Smartflower's automatic daylight tracking. Smartflower's built-in GPS control system tracks the sun from both horizontal and vertical angles, and the panels always follows the sun at 90°. Compared to a static roof system, Smartflower is able to maintain power supply from sunrise to sunset, achieving up to 40% of electricity production. Combined with battery storage, it can not only cover daytime electricity consumption, but also effectively meet nighttime power demand through long-term accumulation during the day.At the same time, because the thermal module will lose power transmission, Smartflower sets the automatic ventilation and cooling system to dissipate the hot air generated by the working operation, prevent the module temperature from being too high, improve the transmission efficiency of 10% compared with the traditional power generation system, and enhance the safety of use and prolong the service life. The basis for various optimized conversion capabilities is that Smartflower's solar panel fan can be expanded up to 18 square meters, receiving large-area light sources and converting them. Depending on the location, an average of about 6,200 kWh of electricity per year can be used to fully meet the average electricity consumption of a Hawaiian family for one year, which is basically enough for everyday use. Smartflower automatically unfolds the solar panel with the sunrise, automatically fold the protection at night, and at the same time helps to remove dust, snow, etc. by folding and unfolding its own fan, maintaining the panel function and maintaining the conversion ability. Smartflower also has self-protection capabilities. During operation, the built-in sensor continuously monitors the wind speed. Above 34 mph wind speed, the fan surface is automatically folded to a safe position to avoid damage; if the wind speed is further increased to 39 mph, it is completely folded, and when the wind is detected to decrease, it is again deployed back to work. Another major advantage over traditional rooftop power generation systems is that they are easy to install. There is no need to have a professional installation on the roof, just by attaching the base anchor to the floor.Thus, with the nature that the fan can be folded, the Smartflower is very portable, and can be moved away even if moving, without complicated installation and disassembly. By this nature, the team also put forward other ideas for the application of Smartflower, such as the provisional outdoor power generation needs as an outdoor temporary power plant when needed. At the same time, compared to other generators, such as diesel generators, it does not generate excessive noise, harmful smoke, and does not need to continuously purchase and transport diesel, but 100% clean and environmentally friendly power supply. It can even extend its use to commercial or utility potential as a source of electric bicycles and automotive power.
