  On December 11, six industry-leading companies including Trina Solar, Canadian Solar, Risen Energy, Chint Solar, Tongwei and TCL Central jointly launched a joint initiative to promote the development of 700W+. The content is as follows: Dear photovoltaic colleagues: China's photovoltaic industry has gone through decades of ups and downs. With the continuous innovation of technology and the continuous expansion of scale, it has become the most competitive and influential industry in the world, making great contributions to the development of clean energy around the world. . For more than ten years, the industry has continuously explored the potential of the manufacturing industry chain and solar energy systems, allowing the power of a single solar panel to be upgraded from the initial 100W+ to today's 700W+.

  In recent years, the global household battery energy storage market has developed rapidly. Its main developments are concentrated in several leading markets including Germany, Italy, Japan, the United States and Australia. Germany Germany is the earliest large-scale household battery market. In May 2013, the German government launched a subsidy program administered by KfW that provides subsidies for energy storage systems installed alongside new or existing solar systems under 30kW. This has propelled Germany into the world's largest market for residential solar and batteries, with installation rates remaining stable even as subsidies have been reduced year by year. In 2022, the installation rate of rooftop solar cells will exceed 75%, one of the highest installation rates in the world. Subsidies have supported the market's growth for more than a decade, but they have slowly shrunk and are no longer the main driver. Instead, the market is now driven by customers committed to increasing their own on-site solar consumption, as they can save more than €0.30 per kilowatt-hour by purchasing electricity from the grid, while exporting solar power for less than 0.30 euros per kilowatt-hour. 0.05 euros. Italy In 2022, Italy will become the second largest market, accounting for more than 20% of the global new market in 2021 and 2022. In 2022, the adoption rate of rooftop solar cells is 77%, up from 11% in 2018. This follows the launch of Italy's extremely generous "Super Bonus" subsidy program in 2020, which covers 110% of all home energy improvement-related costs. After the program launched in 2020, adoption rates increased dramatically. But after the "super bonus" program was scaled back in early 2023, adoption rates suddenly dropped. Unlike Germany, the Italian government quickly withdrew this support program, and the market was unable to sustain growth without the program. BNEF expects adoption rates to remain moderate. The 50% state tax rebate scheme remains in place, which had already given a boost to a number of projects across Italy before the "super bonus" scheme was introduced. Consumers also receive regional subsidies. For example, in Lombardy, solar-battery products enjoy a 50% tax rebate starting from 2016. China China's household battery market has struggled to take off due to China's relatively low electricity rates and limited concerns about energy supply resilience (low blackout rates). In the first half of 2023, the average electricity price for Chinese households was less than 0.530 yuan ($0.076)/kWh, which is approximately equivalent to 50% of the average U.S. household electricity price and 15% of the German household electricity price. Due to cross-subsidies from industrial and commercial end-users, household electricity prices in China are artificially low. Low electricity prices make consumer energy storage projects economically unattractive. For China's electricity users, the losses caused by grid outages are also less ...

Recently, the world's largest single solar energy power plant project, the El Daffra PV2 solar power plant contracted by SINOMACH, was fully completed. The Al Dhafra PV2 solar power station project in the United Arab Emirates, located in Abu Dhabi, is currently one of the largest single photovoltaic power stations in the world. It is also a landmark EPC project in the field of green energy under my country's "One Belt, One Road" initiative. The project covers an area of 20 square kilometers and has an installed capacity of 2.1 GW. It adopts the world's advanced photovoltaic power generation technology and is equipped with nearly 4 million solar panels, 300,000 pile foundations, 30,000 sets of solar tracking brackets, more than 2,000 cleaning robots, 8,000 With 3 string on grid inverters, 180 box-type transformers and more than 15,000 kilometers of cables, the power station performance and power generation efficiency are world-leading. As of mid-November 2023, the project has contributed a total of 3.6 billion kilowatt-hours of clean electricity to the UAE. After completion and operation, the power station can provide electricity for 200,000 residents, helping Abu Dhabi reduce carbon emissions by 2.4 million tons every year, increasing the proportion of clean energy in the UAE's total energy structure to more than 13%, and providing support for the sustainable development of the UAE's national energy economy. Contribute.

Recently, the German Engineering Association VDI stated that Germany’s new photovoltaic installed capacity this year may far exceed the government’s target. According to the association’s report, Germany’s newly installed photovoltaic capacity will reach 13GW this year, while the government’s target is 9GW. VDI said: "Photovoltaic technology is gradually becoming the cornerstone of Germany's electricity supply. The solar industry is optimistic that it will achieve the German government's goal of increasing installed photovoltaic power capacity from about 78GW currently to 215GW by 2030, an increase of almost two times. times." However, VDI renewable energy expert Gerhard Stryi-Hipp warned that the top priority is to further develop Germany's energy market and ensure that the growth in the share of intermittent renewable energy does not reduce Germany's high level of supply security. The association also called for the diversification of solar energy system production countries to reduce "dependence" on China and strengthen international competition. The association said: "Germany still has a high level of expertise in solar energy and production technology, which makes it possible to rebuild photovoltaic production capacity and participate in the strong growth of the photovoltaic market. Germany plans to use solar photovoltaic power generation as one of its core energy sources, with the goal of By 2030, the proportion of renewable energy in electricity will be increased to 80%.”

As energy markets evolve, the rise of Distributed Energy Resources (DERs) and microgrids is revolutionizing how businesses and communities manage their energy needs. Microgrids and DERs empower energy consumers to become producers, creating resilient, efficient, and self-sustainable energy ecosystems. To work seamlessly, two key parts need to be aligned. The hardware (DER’s) and how it’s operated (software-based energy management). Why Microgrids and Distributed Energy Resources (DERs) are Transforming the Energy Landscape Microgrids are localised energy grids that can operate autonomously from traditional grids. They incorporate DERs, such as solar panels and energy storage systems, to generate and distribute electricity. This development addresses the need for reliable, sustainable, and efficient energy sources. The surge in popularity in relation to DERs and microgrids can be attributed to many different factors. Yet, from a business perspective, it’s clear that autonomy & resilience, sustainability, and cost efficiency are the leading causes for this revolution. Decoding the Role of DERs and Software Solutions in Modern Microgrid Technology The profound importance of Distributed Energy Resources (DERs) within microgrids’ complex architecture must be understood to appreciate and take advantage of their enormous potential fully. The functionality and effectiveness of microgrids are greatly improved by these DERs, which also include solar panels, energy storage systems, and wind turbines. Thanks to their invaluable contributions to energy production, storage, and management, they are firmly established as an integrated and interdependent part of the overall system. However, using specialized software solutions becomes necessary to utilize microgrids and DERs fully. Working with a seasoned technology partner knowledgeable about microgrids, renewable energy, and DERs can change your life by providing priceless knowledge and experience.
