Sumitomo Electric launches vanadium redox flow battery with 30-year lifespan
Sumitomo Electric’s new system comes in three versions, providing up to 10 hours of storage. It achieves improvements in output and energy density, through component enhancements, thereby reducing cost and physical footprint.
Jolywood releases 595 W bifacial TOPCon solar panel for harsh environments
The Chinese manufacturer said that its new glass-backsheet Windproof module utilises a zinc-aluminum-magnesium surface alloy technology and a high-strength steel substrate. It features a power conversion efficiency of up to 23.03%.
PV manufacturers making move to coated backsheets
Hard-pressed Asian solar manufacturers have switched from multi-layer polymer backsheets to a single layer of polyethylene terephthalate (PET), with a protective coating on both sides of their modules. Backsheet makers confirm these products, known as “CPC,” are now mainstream. There is little evidence to demonstrate that they can withstand 30 years-plus of outdoor use, however.
Trinasolar inks storage solutions AI research deal with Singapore university
Trinasolar has signed a technology research collaboration agreement with Nanyang Technological University in Singapore to develop artificial intelligence-driven tools to enhance diverse energy storage applications.
Winaico to launch 515 W heterojunction solar module with 23.5% efficiency
Winaico says it will start selling 515 W solar modules with 23.2% efficiency in April 2025.
Risen claims 30.99% efficiency for perovskite-silicon tandem solar cell
The result was confirmed by China’s National Solar Photovoltaic Product Quality Supervision and Inspection Center. The tandem device is relying on a bottom cell based on a heterojunction design.
Tongwei drops plan to acquire Runergy
Chinese PV company Tongwei originally intended to invest CNY 5 billion ($1.8 billion) to buy a 51% stake in Runergy.
Water-based recycling of perovskite solar cells
An international team has developed a new technique to recycle perovskite solar cells (PSC) made on glass substrates using a water-based solution. Tests showed that the recycled cells were as efficient and stable as the original devices.
Study shows reducing number of solar modules per string reduces hotspots risk
Scientists in Indonesia have investigated early operational defects in a 24.9 MW solar PV system in Sumatra and have identified hotspot formation as the dominant defect. They also detected 282 cases of glass cracking, 350 cases of junction box failures and shading effects linked to module defects.
Gurin Energy completes 75 MW PV project in Philippines
The ground-mounted 75 MW project features more than 136,000 solar panels deployed across an 80-hectare site. Retail electricity units belonging to Philippine power company AboitizPower will offtake the energy produced.
