The US microinverter producer and the German panel maker have launched a residential glass/glass PERC module equipped Enphase IQ 7+ device. The 60-cell PERC module is available in three versions with power output ranging from 320 to 330 W and efficiencies of 18.8% to 19.4%.
Chinese PV Industry Brief: Tongwei halts polysilicon output due to flood threat
A unit of the manufacturer has suspended poly production in Sichuan province because of flooding fears. The temporary factory shutdown will shave 25% off the group’s output capacity.
German researchers identify source of impurities in multicrystalline silicon
Scientists from Fraunhofer IISB, Wacker Chemie and Alzchem say unwelcome metals enter the silicon primarily through coating of the quartz crucible. The finding could enable manufacturers to make predictions about the quality of silicon blocks.
A closer look at JA Solar’s new 785/810 W panel series
According to the product sheet, the new series has dimensions of 2,219×1,765x40mm and weighs 43.5kg. Efficiency reportedly ranges from 20.1-20.8% and the module features a 12-year product warranty and 25-year linear power output guarantee.
Solargiga issues profit warning
The decision to remove its cell manufacturing capacity has prompted hefty impairment losses which, together with a Covid-19-related slump in demand, will wipe out the gains offered by new solar ingot, wafer and module production lines.
Xinte corrects update which said it was selling polysilicon at a bargain basement price
Whoever published the figures for a profit warning issued by the poly maker on Friday might have spooked investors even further with a stray decimal point.
Testing CPM-based passive cooling for CPV systems
An international research team has tested change material heat sinks for heat management on a concentrator photovoltaic system. It found that increasing over height ratios lowers the formation of stratified liquid layers, which in turn reduces the potential hot spots in the upper part of the solar cell.
Brazil imported 2.5 GW of PV panels in first half of 2020
According to a recent report from Brazilian consultancy Greener, the country imported 1.61 GW of panels in the first quarter and 877 MW in the second. Domestic PV module makers had a 4.4% market share with around 100 MW in shipped modules in the first half of the year. The analysts claim these figures show the Brazilian PV market has not been affected by the Covid-19 crisis.
Chinese PV Industry Brief: Production expansion plans for Trina, JA Solar, ZNshine
Trina Solar said this week that it plans to expand cell production output by 10 GW at its factory in Jiangsu province, while JA Solar revealed plans to ramp up wafer production by 20 GW. ZNshine Solar, meanwhile, is aiming for 10 GW of new PV module capacity.
SMA reports 42% increase in turnover, Meyer Burger swings to a loss
