How to reduce PV module temperature with frame perforations
Scientists in China have investigated how frame perforations can help reduce the operational temperatures of solar modules through air cooling. Their findings show that the number of perforations must be carefully calibrated, and that more is not necessarily better.
Researchers develop antimony-doped n-type silicon ingots to enhance solar module mechanical strength
An international team is proposing to use antimony-doped Czochralski-grown silicon as an alternative to n-type silicon for photovoltaic applications. Their analysis showed that 140 μm as-cut planar antimony-doped wafers exhibit slightly higher mechanical strength compared to common wafers doped with phosphorous.
AlphaESS launches all-in-one storage systems for C&I applications
Chinese energy storage manufacturer AlphaESS says its new Storion-H30-G3 and Storion-H50-G3 systems combine full integration, higher efficiency, and modular scalability to improve project safety and returns for commercial and industrial (C&I) users.
China’s new auction system drives steep solar price declines
Wood Mackenzie says first provincial auctions under China’s new pricing rules pushed solar bids up to 32% below settlement, signaling tighter margins and a shift to slower, more sustainable growth.
GoodWe debuts PV-driven heat pump water heaters
The Chinese manufacturer said their new residential heat pump water heaters deliver a coefficient of performance of up to 4.2, with a heating capacity ranging from 4.5 kW to 5 kW. The units are available with water tanks in 200 L, 300 L, and 500 L sizes.
Chinese PV Industry Brief: DK Electronic starts copper paste production
DK Electronic Materials has launched mass production of high-copper paste, with full gigawatt-scale manufacturing lines to be operational by the fourth quarter.
Photovoltaic-thermoelectric generators can boost power beaming efficiency
Researchers from China and United Arab Emirates tested a photovoltaic-thermoelectric generator module performance in the receiving end of a laser wireless power transmission system. Under varied atmospheric turbulence conditions, they found the device was able to address thermal stress and improve PV receiver performance.
Fairland launches AI-based residential heat pump with coefficient of performance of 7
The Chinese manufacturer stated that its new heat pump system is the first on the market to achieve a coefficient of performance of 7. The product offers a nominal capacity ranging from 11 kW to 16 kW and uses propane as its refrigerant.
Longi reveals back-contact PV test results from offshore environments
The Chinese manufacturer claims back-contact Hi-MO 9 modules outperformed TOPCon counterparts in a six-month offshore test, showing higher power yield, better low-light performance, and lower operating temperatures.
Battery shortage intensifies as 100 Ah cells sell out into 2026
Orders for small-format 100 Ah cells now stretch into early 2026, with prices up more than 20% as demand outpaces capacity despite aggressive expansion by Chinese battery majors.
