Midea launches air-to-air heat pump for high latitudes
Conceived for Nordic conditions, the Raynor heat pump features a seasonal coefficient of performance of 5.1 and a cooling seasonal energy efficiency rating of 9.2.
DAS Solar enters back-contact business with 5 GW cell factory
DAS Solar has filed an environmental-impact assessment (EIA) for a 5 GW back-contact (BC) solar cell plant in Guizhou, China, expanding its existing manufacturing operations to supply large-scale and building-integrated PV (BIPV) installations.
Improving TOPCon solar cell performance with rear treatment techniques
Researchers in China have investigated four strategies that minimize TOPCon solar cell surface recombination centers and improve light trapping performance. They identified alkali polishing with micro-texturing as the most suitable technique to improve TOPCon cell open-circuit voltage and fill factor and the overall device performance.
Marstek Energy throws down a price gauntlet with new balcony battery
The price point for the 2.12 kWh storage system marks a big chance in the value proposition for those interested in adding balcony storage.
China targets 180 GW of new energy storage by 2027 in ambitous national plan
Announced by the National Development and Reform Commission (NDRC) and the National Energy Administration (NEA), the new plan is expected to drive CNY 250 billion ($35.1 billion) in sector investment.
Chinese PV Industry Brief: Tongwei, GCL and Daqo post steep H1 losses
Tongwei, GCL Technology and Daqo New Energy all reported steep first-half 2025 losses on weak polysilicon prices, with rising n-type output and cost controls failing to offset margin pressure.
Yunt releases MPPT module with 4 independent trackers for C&I use
The Chinese company says that the new product is available in 40 kW, 50 kW, and 60 kW versions. The product has a maximum efficiency of 99%.
China’s intelamp sets world record for solar-powered LED display
Chinese solar lighting company intelamp set a new world record for the largest display of solar-power LEDs with an array of 36,862 of its solar lights in the Mingsha Mountain dunes of western China.
Chinese scientists develop colorless solar concentrator for PV windows
The research team’s semi-transparent solar concentrator can be directly coated onto standard window glass. It uses liquid crystal films to reflect and guide circularly-polarized sunlight to solar cells installed toward the edge of a window. A 1-inch diameter prototype was found capable of directly powering a 10 mW fan under sunlight.
Canadian Solar presents 660 W ‘low-carbon’ heterojunction module with 24.4% efficiency
The new products are available in nine versions with power output ranging from 620 W to 660 W and power conversion efficiency spanning from 23.0% to 24.4%. Canadian Solar said the panels have a carbon footprint of 285 kg CO₂eq/kW, which is reportedly one of the lowest among all silicon-based solar modules worldwide.
