Cooling PV panels with stagnant water layer
Researchers have developed a stagnant water layer cooling concept and tested it using seawater, tap water, and desalinated water. The panel temperature decreased by up to 8.2 °C, while power output increased by approximately 28%.
Austria opens final €8 million solar-plus-storage rebate round
Vienna’s third and final subsidy call offers €8 million ($9.2 million) in incentives and a 10% “Made in Europe” bonus for new or expanded solar-plus-storage systems.
Chemitek Solar launches cleaning solutions for agrivoltaics
Portugal-based Chemitek Solar is developing biodegradable cleaning and anti-soiling products for PV panels that share land use with agricultural production.
Scientists develop new floating box array for offshore PV
Researchers have tested a 9 x 11 floating box array for offshore photovoltaics in a large wave flume, under regular and irregular wave sequences. They have placed wireless gyroscopes on three of the boxes, representing the front, middle, and rear positions.
Solar fridges for the developing world
As climate change leads to more electricity blackouts and brownouts, the reliability of everyday refrigeration is at risk. A new IEC Standard, together with solar innovations in Africa and Asia, demonstrates how cooling can continue when power grids falter.
Optimal sizing for AC multi-bus microgrids based on solar, storage
A French–Moroccan research group has developed a two-stage hierarchical techno-economic model to optimize AC multi-bus microgrids in remote areas. This microgrid configuration is more complex than that of standalone systems but offers several advantages in terms of cost efficiency and energy reliability.
French startup launches solar-based EV charging optimization system
DejaBlue has developed a plug-and-play energy management system that boosts self-consumption and cuts costs for PV-powered EV charging sites.
Sermatec’s 6.25 MWh battery storage system enters mass production
The Chinese manufacturer reports that it has established automated production lines and a mature supply chain to support large-scale deliveries, with initial shipments scheduled to begin in the fourth quarter of 2025 in China.
Sentorise releases 100 Ah battery for off-grid use
The Chinese storage system manufacturer said its 12.8 V product is designed for RV travelers, off-grid homeowners and marine users. It reportedly provides over 6,000 cycles at 90% depth-of-discharge.
Chile’s energy storage capacity reaches 4.6 GWh
According to data from the Chilean Association of Renewable Energy and Storage (ACERA), the share of non-conventional renewable energy in Chile’s electricity grid rose to 39.5% of total generation in August.
