CATL secures world’s largest sodium-ion battery order with Hyperstrong
The two companies announced a 60 GWh supply agreement on Monday, marking a pivotal step in the commercialization of sodium-ion battery technology.
Huaneng energizes 5.4 GW hydro-solar complex in southwest China
Huaneng has commissioned the 5.43 GW Xiaowan Hydropower–Solar Hybrid Project in Yunnan, combining 4.2 GW of hydropower and 1.23 GW of solar under a coordinated “hydro–solar intelligent control” system integrating 16 PV plants.
Trina Solar claims world’s highest efficiency for silicon solar cells with 28.0%-efficient device
The Chinese manufacturer said its TOPCon-compatible hybrid back-contact solar cell achieved a power conversion efficiency of 28.0%. The result was confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH).
Premier Energies unveils 600-630 W all-black TOPCon solar modules
The Indian manufacturer said its new all-black panel series features a power conversion efficiency of up to 23.32% and a bifaciality factor of up to 85%.
Chinese scientists build silver-free heterojunction solar cell with 25.2% efficiency
The research team developed a plasma interface engineering method to improve indium tin oxide layers, solving adhesion, contact resistance, and stability issues for copper electroplating. The optimized process enabled uniform copper metallization and boosted device efficiency to 25.2%, significantly outperforming untreated reference cells.
Two-year testing shows how PV plants increase local temperatures in semi-arid regions
A two-year field study in a 100 MW photovoltaic plant in semi-arid Inner Mongolia combined ground-based sensors, radiation measurements, and UAV thermal imaging to quantify how large-scale PV installations alter local air temperature, surface temperature, and energy balance compared with nearby non-PV areas. Results show consistent site-scale warming of 0.8 C.
Chinese solar exports surge 125% in March on policy change rush, not underlying demand acceleration
The Chinese customs data show a March surge as buyers rushed shipments ahead of April’s tax-rebate change.
Pakistan plans to scrap licensing fee for PV systems up to 25 kW
The move seeks to reverse aspects of the Nepra Prosumers Regulations 2026, which centralized approvals and is creating delays and financial barriers for rooftop solar adoption.
Record solar, wind surge drives 3.3% drop in India’s fossil generation in 2025
India’s renewable power generation from solar, wind, hydro and bioenergy rose by a record 98 TWh (+24%) in 2025, driven by strong growth in solar and wind, according to Ember. The increase was twice the country’s electricity demand growth of 49 TWh, which was relatively low due to milder temperatures and slower industrial activity. As a result, India’s fossil power generation fell by 3.3%.
U.S. government sets preliminary anti-dumping duties on solar imports from India, Indonesia, and Laos
The U.S. Department of Commerce has issued preliminary anti-dumping determinations for three key solar-exporting nations, establishing duties of up to 123% on crystalline silicon photovoltaic cells and modules.
