China expects up to 287 GW of new PV capacity additions in 2026
China’s PV industry expects 238 GW to 287 GW of domestic capacity additions in 2026 as it pivots away from volume-led growth after a loss-making year driven by overcapacity and sharp price declines. The shift follows rapid expansion in 2021-25 that lifted cumulative capacity above 1.2 TW, annual additions beyond 300 GW and exports over $180 billion.
Deye releases new off-grid inverter series
The Chinese manufacturer said its new OG02 series includes IP-65-rated inverters with an AC output power of 3 kW to 6 kW. The new products also feature a maximum efficiency of 97.6% and a European efficiency of 96.5%.
DAS Solar unveils new method to identify hot-spots in TOPCon back-contact solar modules
The Chinese manufacturer said it developed a new circuit-model–based method to accurately detect hot-spot risks in TOPCon back-contact modules, overcoming limitations of the IEC 61215 approach caused by low shunt resistance. Validated through indoor and outdoor tests, the method predicts temperature rise under shading and reportedly enables faster, more accurate hot-spot risk assessment.
