The French Transitional Ministry of Ecology and Solidarity announced the results of the 13th round of tenders for 324 MW of commercial and industrial rooftop solar power generation capacity. The capacity of these systems is between 100 kilowatts and 8 megawatts. The Ministry has allocated 211 megawatts of rooftop solar mounting bracket power for category A projects, ranging from 100 kilowatts to 500 kilowatts. The tender found that the average electricity price for Type A projects was 87.25 Euros (approximately US$98.86)/MWh. For the capacity of 500 kilowatts to 8 megawatts, the category B roof project won the bid for about 113 megawatts. The tenderee found that the average electricity price of a Type B roof project was 76.66 Euros (approximately US$86.86)/MWh. According to data released by the French Data and Statistical Research Department, France installed 2,034 megawatts of solar film clamp power in the first nine months (9 million), an increase of 167% from the 761 megawatts installed in the same period last year (year-on-year). The ministry said that the 900 2021 facilities are mainly concentrated in the southern half of the French mainland. As of the end of September 2021, France has accumulated 13.2 kilowatts of solar power plants. Of the 13.2 GW of solar power generation capacity, 12.58 GW of solar power generation capacity is located in mainland France. Nouvelle Aquitaine has a maximum capacity of 3.16 GW. Occitanie and Auvergne Rhäne Alpes have installed solar capacity of 2.58 GW and 1.44 GW, respectively. In 9 million by 2021, France's solar power generation capacity reached 12.5 trillion kilowatt-hours, an increase of 9% year-on-year. It accounts for 3.7% of total electricity consumption in France. In August 2021, the European Commission approved a €5.7 billion (US$6.7 billion) aid program to support renewable energy generation from small solar installations in buildings located in France. This measure is expected to help the country achieve its 2030 goal of using renewable energy to produce 33% of its energy needs and help achieve Europe’s goal of achieving climate neutrality by 2050. Last year, France selected 100 solar and wind energy projects in an auction, with a cumulative power generation of 600 megawatts. The government has selected 45 ground-based solar end clamp projects with a cumulative installed capacity of 332 megawatts. The average electricity price of the selected projects was 57.4 Euros (approximately US$68.10)/MWh, a decrease of 7.4% compared with the previous auction. It also selected 31 self-use solar projects with a total capacity of 9 MW. The average electricity price of these projects is 13.8 Euros (about 16.36 USD)/MWh, which is a 14% drop compared to the previous auction.

According to foreign media reports, researchers have developed a composite material panel that can be used as a photovoltaic cell to generate electricity from solar energy by mounting brackets, and at the same time as a structural supercapacitor to store energy. In electric vehicles with ion-exchange rechargeable batteries, these panels can be used for body structures and form a hybrid energy storage system (HESS). Compared with traditional electric vehicles, under solar irradiance of 1000W/m 2, this type of solar composite end clamp board prototype can provide an additional 4.56% of power generation and cruising range per hour. Use solar supercapacitors as electric car body panels In electric vehicles, with the help of cost-effective hybrid energy storage systems, several types of renewable energy sources can be integrated to improve efficiency. Among them, compared with fuel cells and electrochemical cells, supercapacitors have many advantages, such as higher power density, shorter charging time and longer cycle life. It is common to use photovoltaic cells on the RV bracket roof to collect solar energy. However, using the same equipment to store this type of energy may change the rules of the game in the field of hybrid electric vehicles. Solar Super Capacitors (SSC) are capacitors used to collect and store solar energy. Carbon materials are the most commonly used electrode materials in supercapacitors, and carbon fiber (CF) has proven to be the best candidate material for electric double layer capacitors (EDLC). Benefiting from one-dimensionality, CF has superior charge transport performance. Because of the large number of pores on the fiber surface, CF has a high adsorption capacity for ions. Conductive polymers such as CF and epoxy resin (ER), together with metal oxides such as ZnO/CuO, can be used as high-performance SSC electrodes.

The United States Bureau of Land Management (BLM) has invited letters of intent to lease 89,589 acres of public land in the Solar Energy Zone (SEZ) to develop solar mounting bracket projects in Colorado, New Mexico, and Nevada. The final date for submission of the letter of intent is January 20, 2022. In Colorado, the agency expects to lease 9,712 acres in the Antonio Southeast Special Economic Zone, 1064 acres in the Detilla Canyon Special Economic Zone, and 2,650 acres in the Los Mogotes Eastern Special Economic Zone. In Nevada, it will lease 25,069 acres in the Dry Lake Valley of the North Special Economic Zone, 4,569 acres in the Golden Point Special Economic Zone, and 16,534 acres in the Miller Special Economic Zone. 29964 acres of land in the Afton Special Economic Zone is expected to be used for solar end clamp projects in New Mexico. According to the Bureau of Land Management, of the 245 million acres of public land it manages, approximately 870,000 acres have been prioritized for solar film clamp development. If 8.5 acres of land are required to develop a 1 MW solar project, the land allocated by the project can support more than 100 gigawatts of solar capacity. The electricity generated by these solar projects can meet the electricity needs of more than 29 million households. In addition to the priority land for solar energy development, the agency also reserves 19 million acres of additional land for potential solar energy development. Earlier this month, the Platte River Power Authority (Platte River Power Authority) issued a request for proposal (RfP) to acquire 250 MW of solar energy and/or co-located battery storage project. The power company will acquire projects that are expected to start power supply on January 1, 2025, and ensure that the commercial operation date will not be later than June 1, 2025. The Solar Energy Industry Association and Wood Mackenzie said in a joint report that the US’s solar power generation in the second quarter reached a record 5.7 kilowatts, an increase of 45% over the same period last year. According to a report from the Lawrence Berkeley National Laboratory (LBNL), by the end of 2020, the capacity of solar pipelines in the United States will be approximately 460GW. Among them, 160GW or 34% of the projects include battery storage facilities.

According to the Polish Energy Management Office, in the latest round of renewable energy tenders held earlier this month, Poland allocated about 870MW of solar photovoltaic mounting bracket projects. The bidding for solar and wind energy projects with a capacity of more than 1MW has ended. The solar bidder has won a 570MW project with a minimum bid of 0.20785 zloty/kWh (0.05072 USD/kWh), which is slightly lower than that in Poland earlier this year. The lowest bid price of the project. The total amount of onshore wind power winning bids is 460MW. In another bidding for solar and wind power projects below 1MW, 182 participants submitted 401 bids, all of which were photovoltaic projects. The lowest bid price for this tender is 0.219 zloty/kWh (0.05344 USD/kWh), and it is planned to build a solar energy middle end clamp project with a total volume of about 300MW Poland is expected to develop about 3.2GW of solar energy this year URE stated that due to the large number of bids submitted, the basis for selecting the winning bidder is not only the price, but also the order of bidding. The third tender was also held for hydropower, biomass and geothermal projects. In these three tenders, more than 96% of the winning proposals came from solar energy companies. In the latest round of tenders announced at the end of October, Poland allowed bidders for the first time to submit bids for hybrid renewable energy projects. The bidders could combine solar photovoltaic power plants and wind power plants. However, at the end of the bidding, no mixed bid proposal was received. The winning companies in the latest round of tenders include Swedish developer OX2, which has won 28MW solar and nearly 120MW wind power projects. Katarzyna Suchcicka, manager of OX2 Poland, said: "In order to reduce the price of electricity for Polish consumers and to reduce the local pollution of fossil energy, we need more and more wind energy and photovoltaic projects." To help Poland achieve its environmental goals, the European Commission recently approved the extension of Poland’s renewable energy tender program until the end of 2027. According to a research report published by the trade association SolarPower Europe last week, in 2020, Poland developed about 2.5GW of solar energy, and this year another 3.2GW was added. The association stated that in addition to the tender, favorable self-use plans and net metering systems have also promoted the development of photovoltaics in Poland. The tax rebate plan of the net metering system and the household system complement each other. This year, solar developer Lightsource bp announced that the company will enter the Polish solar film clamp market through the cooperative development of the Polish 757MWp project. Earlier this year, independent power producer RP Global stated that the company is developing solar and wind energy projects in Poland and plans to deliver more than 1GW of projects.

Recently, the US International Trade Commission put forward a proposal that from February 2022, the implementation period of the "201 tariff" for imported photovoltaic cells and modules will be extended by 4 years. Regarding this proposal, the American Solar Energy Industry Association and many other industry organizations have raised objections, saying that the imposition of tariffs on photovoltaic imports has not only failed to protect the domestic manufacturing industry in the United States, but has caused tens of thousands of unemployment, and has seriously hindered the development of the domestic photovoltaic industry in the United States. Development will even jeopardize the achievement of the United States’ climate goals. The effect of imposing tariffs for many years has been counterproductive Based on many foreign media reports, the US International Trade Commission recently submitted a report on the domestic photovoltaic manufacturing industry in the United States, stating that “the 201 tariff has played a positive role in adjusting foreign competition.” In the future, the US photovoltaic industry still needs trade protection. It is recommended that the United States The government extended the "201 tariff" for 4 years. Up to now, US President Biden has not made a final decision on this, but the industry has responded strongly. Abigail Ross Hopper, CEO of the American Solar Energy Industry Association, said: "The growth of American photovoltaic manufacturers is critical to the long-term development of clean energy in the United States. However, the effects of photovoltaic tariffs for many years have not been satisfactory. Now the United States has formulated it. Clean energy power installed capacity targets, and extending these tariff deadlines is likely to hinder the United States from achieving this goal." It is understood that in January 2018, the U.S. government proposed for the first time to impose tariffs on imported photovoltaic cells and modules for a period of four years, known as the "201 tariffs." This tariff rate starts from 30% and drops to 15% in the final year, and is expected to expire early next year. According to statistics from the American Solar Energy Industry Association, during the more than three years of implementing the "201 Tariff", the US photovoltaic industry has not only not ushered in a large-scale employment wave, but has lost 62,000 jobs. At the same time, private investment in the photovoltaic industry has lost 19 billion yuan. Dollar. Not only that, in 2018, the total volume of imported photovoltaic cells and new installed capacity in the United States both plummeted to as low as 6.8 million kilowatts, a year-on-year drop of 66.7%. In sharp contrast to this, after the tariff rate has been reduced and partial exemptions have occurred, the installed capacity of photovoltaics in the United States has rebounded. In the view of the American Solar Energy Industry Association, poor financing is the main proble...

German start-up company Solarbakery developed this 52 kW containerized solution. The production process of the bakery has been adjusted so that most of the electricity consumption occurs during the day, and only a short baking is carried out before dawn. A new artisanal bakery is expected to open in Senegal as early as the end of March, serving fresh and delicious bread-and using solar energy to achieve a carbon dioxide-neutral production process. The special feature of this bakery is that it is completely arranged in a container and will be shipped from Munich to Senegal by the German startup Solarbakery. The solar mounting bracket modules and installation system will then be unpacked and installed on site. The equipment of the bakery and a well-divided insulated and air-conditioned room will be located in a container on the ship. The container is almost 14 meters long and 2.45 meters wide. There is also a battery energy storage system embedded in the container, designed to provide enough power for early shifts. The idea for Solarbakery came from Simon Zimmermann. He and a partner have deployed several container bakeries in Kinshasa, Democratic Republic of Congo. Through this business, the company achieved sales of $128,000 in the first fiscal year, but the electricity supply for the bakery is still guaranteed by polluting and expensive diesel generators. As the co-founder of Solarbakery, Zimmermann won the support of Torsten Schreiber. Torsten has been cooperating with Africa Greentec company, committed to the solar electrification of African villages, and is now responsible for converting the containers in the bakery to rely on photovoltaics. To this end, a solar panel end clamp roof was added to the bakery with 144 modules and a total power of 52 kW. The third founder of the company, Daniel Petruccelli, is a baker. He changed the production process so that most of the power consumption occurs during the day, and the finished bread only needs to be heated for a short time before dawn. He also trains employees and devotes himself to developing new recipes. Solarbakery is raising funds through a crowdfunding campaign on the Conda platform, with a goal of 500,000 euros, and now it has raised more than 300,000 euros. Zimmermann said that although there are 17 days remaining in the fundraising period, if the target is not reached within the stipulated time, the crowdfunding may be extended by two months. The money will initially be used to deploy two bakeries. Zimmermann added that one of them will be shipped directly to Senegal, and a production facility is expected to be established in Dakar for the production of more solar bakeries and mobile power stations（Adjustable bracket） by Africa Greentec. The second bakery will initially remain in Germany as a demonstration to persuade investors to invest in the company or directly invest in the solar bakery. In the future, Solarbakery hopes to adopt three different business models. The first i...

With the continuous penetration of the concept of sustainable development in various countries around the world, the global solar energy development and utilization scale is rapidly expanding, and various solar-related products emerge in an endless stream. Here are a few new Japanese solar flim end clamp cells. 01 Toshiba "bent" solar cell Complete the world's highest conversion efficiency Toshiba announced that as part of the New Energy and Industrial Technology Development Organization (NEDO), it has developed a thin-film perovskite solar cell module with a module area of 703 square centimeters and an energy conversion efficiency of 11.7%. It is said that this battery is currently the largest thin-film perovskite solar cell in the world. Currently, mainstream crystalline silicon solar cells have limited installation locations due to their weight and shape. Thin-film perovskite solar cells have the characteristics of good flexibility and light weight, and can be installed in buildings with low load-bearing capacity that could not be installed in the past, as well as ZEB (net zero energy building) and ZEH (net zero). The form of installation, such as installation on the wall, to achieve a zero-energy house. In addition, as next-generation solar cells, they are attracting attention due to their low-cost materials, which can be formed by coating and printing, and can achieve low-cost manufacturing. On the other hand, although the energy conversion efficiency of a small area cell (0.09 cm2) has been proven to be 22.7%, which is close to that of a crystalline silicon solar cell, it is difficult to form a uniform thin film with a larger area. In this case, in addition to the "meniscus coating technology" that uses the meniscus (curved surface formed by the liquid in the gap), Toshiba has also developed a new manufacturing process, specifically, through the development of large Area coating process and design ink composition to control the reaction of lead iodide and methyl ammonium iodide on the substrate. A large area and high efficiency are realized. In addition, by controlling the coating process and optimizing the perovskite crystal growth conditions, the uniformity of the large-area in-plane film and the uniformity of the crystal film quality have been successfully improved. As a result, even 703 cm2 has obtained a conversion efficiency of 11.7%, which is close to the practical module (900 cm2) and one step closer to practicality. In the future, with the goal of realizing a practical module size, the technology will be further developed and the area will be expanded. In addition, by improving the material of the perovskite layer, Toshiba plans to strive to achieve high efficiency comparable to that of crystalline silicon solar cells. 02 The University of Tokyo develops washable solar cells Realize the "power" of clothes The joint research team of the Institute of Physics and Chemistry (RIKEN), the Japan Agency for the Promotion of Science an...

Swiss Solar announced that its new solar photovoltaic module production facility is located in Turkey. The company said that upon completion, there will be three production lines of solar mounting system with an annual capacity of 1.5 GW. By 2027, its goal is to have "at least" 5 GW of manufacturing capacity. Swiss Solar said: "This decision was made because of a severe shortage of products. Even if the output doubles (compared to 2020) and the total annual production capacity exceeds 1 GW, it will not be able to meet the needs of old customers." The company stated that demand growth and favorable forecasts in the solar energy markets in Europe, North America and South America are the main factors affecting the site selection, adding that the convenient transportation and logistics infrastructure in the region provides sea and land transportation to make the choice clear. Swiss Solar stated: “The first phase of the project will involve the preparation of the production area, including the purchase, installation and adjustment of equipment for three photovoltaic module production lines with nominal capacities of 450 Wp, 500 Wp and 545 Wp. Swiss Solar is already in cooperation with the world. Leading manufacturers conduct negotiations, and their names will be announced after the signing of the supply contract." The company said that by 2027, its goal is to have 10 production lines with a capacity of up to 500 megawatts, which will enable it to reach a total annual production capacity of at least 5 gigawatts. The company also plans to produce 590Wp solar bracket photovoltaic modules by then. The company said: "The main promotion work in Europe and North America will be concentrated in the residential sector, while in South America, it will be concentrated in the commercial and utility sectors." According to reports, finished photovoltaic modules（like solar end clamp） will provide a 25-year warranty, and the entire product series is expected to be tested by recognized companies, including TÜV SÜD product Service GmbH, UL (USA), North American TUV Rheinland, TSE Certification Center (Turkey), ANCE-Asociación de Normalización y Certificación, aC (Mexico), and InMetro (Brazil), and passed the following certifications: ISO 14001-2015; ISO 9001-2015; ISO 45001-2018. The company concluded: "The successful progress of the project has allowed Swiss Solar to conclude that the new plant and its innovative products will not only enable the company to meet the needs of its old customers, but also open up new markets."

Serbia plans to develop 8.3 GW solar and 3 GW wind power projects by 2024. According to the "Draft Economic Reform Plan 2022-2024" of the Balkan countries, the total expenditure on energy and mining projects is 17 billion euros (approximately US$19.17 billion), of which 12 billion euros (approximately US$13.53 billion) are used for wind, solar and hydropower project. If all the projects in the investment plan are implemented, it will offset nearly 23 tons of carbon dioxide emissions each year. In addition to the 66 MW Kostolac wind farm (which is already under construction by the state-owned power company Elektroprivreda Srbije (EPS)), the national wind farm project can be built near Zabela and Kovin Dubovac. About 300 megawatts of solar bracket power generation projects, totaling about 200 million euros (about 225.5 million US dollars), can be developed on land belonging to EPS. A public-private partnership with Fintel Energija is also proposed to develop the Maestrale Ring wind farm. The total installed capacity of the national wind farm is 3 GW, with an investment of 3 billion euros (approximately US$3.38 billion). The government proposes to build solar power projects on 200,000 hectares of state-owned land. Approximately 2 gigawatts of solar end clamp projects can be installed on this piece of land. As part of this plan, the Ministry of Mines and Energy and the UGT Renewable Energy Ministry signed a cooperation agreement. These power projects can generate 1 GWh per year, offsetting 1.9 million tons of carbon dioxide emissions. The draft economic reform plan stated that a roof area of 600 square kilometers was determined for the installation of solar mounting systems. The capacity of installing solar systems on 10% of this roof area may reach 6GW, accounting for 70% of Serbia’s installed capacity. The annual production will be 7 TWh, accounting for approximately 20% of Serbia's total production. According to the draft, the government's solar projects can bring in 6.2 billion euros (about 6.99 billion US dollars) of investment. Albania, another Balkan country, has made rapid progress in its plans to achieve its renewable energy goals. Thanks to a loan of 9.1 million euros (approximately US$10.26 million) provided by the European Bank for Reconstruction and Development (EBRD), the country built a 12.9 MW Floating solar photovoltaic power plant. Albania has announced plans to initiate the first tender for the construction of utility-scale onshore wind power projects.
