  Scientific discovery could be key to commercializing zinc metal batteries for large-scale storage

  Scientists led by an Oregon State University researcher have developed a new electrolyte that raises the efficiency of the zinc metal anode in zinc batteries to nearly 100%, a breakthrough on the way to an alternative to lithium-ion batteries for large-scale energy storage. The research is part of an ongoing global quest for new battery chemistries able to store renewable solar and wind energy on the electric grid for use when the sun isn`t shining and the wind isn`t blowing. Xiulei [David" Ji of the OSU College of Science and a collaboration that included HP Inc. and GROTTHUSS INC., an Oregon State spinout company, reported their findings in Nature Sustainability. [The breakthrough represents a significant advancement toward making zinc metal batteries more accessible to consumers," Ji said. [These batteries are essential for the installation of additional solar and wind farms. In addition, they offer a secure and efficient solution for home energy storage, as well as energy storage modules for communities that are vulnerable to natural disasters."

  Jinko and Trina are among Deege Solar's most efficient PV modules

  The efficiency of photovoltaic modules is an important index to measure the conversion of solar energy into electrical energy. Different brands and types of PV modules have different module efficiencies. Most household PV modules typically have efficiencies of 15-18% , with high-quality modules achieving efficiencies of more than 21% . Here are Deege Solar's picks for the most efficient PV modules for domestic PV systems in 2022: Deege Solar is a British PV installer, and Ja and sky are the only two Chinese PV companies selected. From the module model and power point of view, Tianhe 210 Supreme Xiaogang has been promoted and performed well in the European household market. Although the latest 182 household module products from Jingao are not on the list, previous module models also have a higher efficiency, power level. Longji, Jinao and Jinke were among the top 10 Chinese PV companies in the 2022 US household module market efficiency ranking published by Global PV. In recent years, the rapid growth of the global household photovoltaic, photovoltaic enterprises are increasing the layout, Tianhe, jingao, jingke, Longji have launched its consumer market for large-scale Battery module products. Developed areas overseas have a high proportion of independent housing, and have the basic conditions to install household photovoltaic systems. They are relatively mature, thanks to the implementation of the fifteen plan and the county-wide promotion policy, the domestic domestic PV market is also developing rapidly. According to Wang Bohua's latest report, the 2021 installed capacity of domestic PV accounts for 39.4% of our country's new installed capacity, up 113.3% year-on-year. The scale of domestic PV has reached a record high of 21.6 GW.

  Gamesa nearly triples solar inverter sales in 2022

  Gamesa Electric had a record year in 2022 in its solar and storage inverter business, almost tripling the contracted capacity globally compared to 2021. Specifically, during 2022 Gamesa Electric experienced a 182% increase in the megawatts signed compared to the capacity contracted in 2021. The U.S. is Gamesa`s main market, followed by Europe and Latin America. [We are delighted with the strong demand for our products and services this year," said Juan Barandiaran, managing director of Gamesa Electric. [It is a proof of the hard work and dedication of our team and encourages us to continue to innovate and offer our customers top-quality products such as the Proteus inverter." One of the reasons for this successful year has been the launch of the new Gamesa Electric Proteus, a central inverter for solar and storage applications with up to 4.7 MW of power and record levels of efficiency. In fact, 98% of the contracts signed are related to this solution, a clear sign of the great reception it has had among customers. In addition, the Proteus inverter has received the prestigious Intersolar Award as the best solar product of 2022.
