Recently, according to foreign media reports, a serious explosion occurred in Schleswig-Holstein, Germany. A residential building was severely damaged. Judging from the pictures on the scene, the exterior wall of the house was severely damaged. The local volunteer fire brigade reported: "There was a loud bang, followed by a pressure wave. Then thick smoke rose." It is understood that although many parts of the building were burning at the time, the fire was quickly brought under control. Fortunately, the severely damaged building was vacant at the time of the incident, but it may be demolished later. It is understood that this is a single-family villa equipped with photovoltaic + energy storage facilities. According to the North German Broadcasting Corporation NDR, preliminary investigation results show that the cause of the explosion was a failure of the solar energy storage system. At noon that day, photovoltaic power generation had fully charged the energy storage system, but the remaining power was not fed into the power grid and continued to power the energy storage battery, resulting in the explosion.

In the latest ground-mounted PV tender of the German Federal Network Agency, the winning bids hit the lowest record since February 2019.   The winning bids ranged from 0.0388 euros/kWh to 0.0495 euros/kWh, with an average volume-weighted price of 0.0476 euros/kWh, about 6% lower than the average winning bid in the previous round (0.0505 euros/kWh). People's enthusiasm for participation in the German ground-mounted PV tender continued to rise. The tender was oversubscribed by two times, with 524 bids received, totaling 4,708MW. Previous ground-mounted PV tenders also encountered similar oversubscription. In the end, in the tender held on December 1, 2024, the German Federal Network Agency approved a total of 242 bids and signed a total of 2,150MW of PV capacity. "The tendered capacity in this round of ground-mounted photovoltaic tenders was once again significantly higher than the tendered capacity. The continued high level of competition has led to a further decline in the winning bids, which has reduced the public funds available for new projects," said Klaus Müller, President of the Federal Network Agency. In Germany's latest solar project tender, Bavaria ultimately received the most photovoltaic power capacity, with 120 projects totaling 916MW, which is consistent with the results of previous tenders. Schleswig-Holstein followed closely behind, with 231MW of photovoltaic power capacity and a total of 21 projects. Lower Saxony ranked third with 192MW of power capacity and 18 winning projects. Since the adoption of the "Solar Package" last year, this is the first time that the rules for meeting minimum natural environmental protection standards have been implemented in the tender, which aims to improve the compatibility of ground-mounted photovoltaic projects with nature and landscape. On the other hand, in this tender, the measures to increase the maximum capacity of projects to 50MW and the "solar special project" were not applied. The next ground-mounted photovoltaic tender will end on March 1, 2025. Photovoltaic power will take more responsibility for the entire system In other related news, the German government recently adopted several important energy policies. One of the policies stipulates that photovoltaic power will take more responsibility for the entire power generation system. The draft law aims to take measures to address the growing challenge of temporary overgeneration as more renewable power capacity is put into operation. The changes introduced will better integrate power peaks in the grid and strengthen photovoltaic systems while improving network security. The operation of energy storage systems will also be simplified. In addition, the changes are aimed at better handling of negative electricity prices, the controllability of renewable power plants and the controllability of network operators. Robert Habeck, Federal Minister for Economic Affairs and Climate Protection, said: "The decision taken by the Bundestag to...

Recently, the Huadian Laizhou Large-scale Salt-alkali Tidal Flat Photovoltaic Energy Storage Integrated Project, my country's largest tidal flat photovoltaic energy storage power station undertaken by Shandong Electric Power Construction No. 1 Company, was put into operation on the shores of the Bohai Bay, turning a large area of ​​saline-alkali land into a new oasis of clean energy. The vivid practice of "turning salt flats into green beaches" has important strategic significance for the efficient utilization of saline-alkali land resources in my country and the high-quality development of new green energy.   The project is located in the west of Laizhou, Shandong. It is the third batch of large-scale wind power and photovoltaic base construction projects in the country, covering an area of ​​18,000 mu, with an installed capacity of 1,000 megawatts, and supporting the construction of a 200MW/400MWh electrochemical energy storage project. The first batch of 300 megawatts will be connected to the grid for power generation on June 30, 2024, which is an important sign that Shandong Province's new energy installed capacity has exceeded 100 million kilowatts.   The project will build two 220 kV booster stations. After the project is put into operation, it can add 1.442 billion kWh of green electricity each year, save 444,000 tons of standard coal, reduce carbon dioxide emissions by 1.2 million tons, reduce sulfur dioxide emissions by 230.8 tons, reduce nitrogen oxide emissions by 258.1 tons, and reduce smoke emissions by 46.23 tons, with significant economic and ecological benefits. The supporting energy storage phase I 100MW/200MWh electrochemical energy storage project was completed and put into operation at the end of June 2023.   In terms of construction land, the project selected a large area of ​​saline-alkali tidal flats, integrating "photovoltaic power generation + salt production" and realizing the "salt-light complementary" composite industrial model of "water photovoltaic power generation and water surface evaporation brine production".   During the project construction process, considering the protection of the tidal flat ecosystem, the existing salt field cofferdam was fully utilized to partition the photovoltaic array to reduce the damage to the original topography. After construction, the salt pond cofferdam and pipe pile base were repaired for anti-seepage capacity to ensure the improvement of salt field quality.   In terms of design, the photovoltaic panels are 3 meters above the ground, with wide intervals, which provide good lighting and ventilation and are convenient for drying salt. The solar panels adopt a double-sided power generation design, which absorbs direct sunlight on the top while absorbing sunlight reflected from the water surface on the back, thereby increasing the power generation efficiency by about 3%.

Recently, Xinjiang's first photovoltaic technology demonstration base invested and built by Datang Hami New Energy Co., Ltd. was officially put into operation, filling the gap in Xinjiang's photovoltaic industry. A 1 million kilowatt "solar thermal + photovoltaic" integrated clean energy demonstration project was built in Shichengzi area of ​​Yizhou District, Hami City. In view of the current problem that there are many photovoltaic projects in various parts of Xinjiang, but the empirical research on related technologies is insufficient, a photovoltaic technology demonstration base with a total installed capacity of 40,000 kilowatts was built in this project to conduct empirical research on the "combination" of 36 technologies and equipment, and installed a large number of testing equipment, which can form data analysis reports in real time and realize the real-time data collection and analysis of all elements and processes of various photovoltaic equipment. At present, the cost of electricity per kilowatt-hour in the photovoltaic field continues to decrease, the efficiency of photoelectric conversion continues to increase, and the forward-looking requirements for technology and equipment in the construction of photovoltaic projects are increasing. This demonstration base will make up for the insufficiency of the laboratory's inability to fully simulate the outdoor environment by conducting outdoor performance demonstration experiments on equipment, provide data support and industry guidance for the promotion and application of new technologies, new products, and new materials, and at the same time promote industry technological progress and industrial development by establishing a dynamic database of outdoor empirical applications of different products.
