Big wafer benefits extend to n-type, says Trina Solar
China’s Trina Solar has published a white paper on its latest n-type TOPCon modules, with cost calculations and figures from demonstration projects. The Chinese PV manufacturer claims better performance from its 210 mm cells than with other n-type products based on smaller, 182 mm cells.
TBEA unveils new residential inverters
TBEA has developed new products with nominal power ratings of 10 kW to 25 kW and efficiencies of 98.5%.
Canadian Solar reveals plans to set up 14 GW of solar cell, module capacity
Canadian Solar says its cell and module capacity will reach 50 GW by the end of this year.
General Electric switches on 1.2 GW pumped hydro facility in China
General Electric has switched on two more 300 MW pumped storage turbines at a 1.2 GW hydro battery complex in China’s Anhui province, after finalizing the facility’s first 600 MW unit in December. The project has completed a trial period and commercial operations are now fully underway.
China mulling restrictions on polysilicon, wafer production tech exports
The Chinese government is considering the introduction of export restrictions on solar wafers, black silicon, and silicon casting equipment. It has launched a public consultation process on the proposed measures.
Novel snow-removal tech uses electricity from uncovered PV panels
JA Solar has worked with Chinese scientists to test a new electrical heating system for solar panels that uses the heat from uncovered panels to remove snow. The system starts by using grid electricity, but then relies on the thermal effect of resistance to uniformly heat the whole PN junction area of the snow-covered panels.
TÜV Rheinland opens solar module testing lab in China
Germany’s TÜV Rheinland said it will invest €22 million in the 5,000 m2 facility for testing photovoltaic modules as part of a massive lab.
Spray passivation to reduce losses in TOPCon, HJT cell-to-module process
Chinese researchers have developed a new passivation technique for shingled solar panels based on tunnel oxide passivated contacts (TOPCon) or heterojunction (HJT) tech. It reduces recombination losses in the cell-to-module process and reportedly increases open-circuit voltage, fill factor, and efficiency.
JA Solar to build new vertically integrated solar factory in China
JA Solar says it will build a new manufacturing facility in Inner Mongolia, China. The plant will produce everything from polysilicon to solar panels.
Renac unveils high-voltage hybrid inverters for residential applications
Renac Power’s new hybrid inverters have efficiency ratings of up to 97.5% and European efficiency ratings of 97.2%. They are available in four versions, with power outputs ranging from 3 kW to 6 kW.
