Solar 101: The brains behind the beauty of your solar power system
In addition to converting the output of PV panels from DC to AC, inverters now perform a number of other functions, such as maximizing electricity generation, assessing performance and even shutting down in emergencies.
Risen Energy plans 3 GW cell, module factory in Malaysia
China-based Risen Energy is expanding its global footprint with plans to construct a $10 billion production facility in Malaysia.
PV-driven air conditioner coupled with ice thermal storage
Researchers in China have built a PV-powered air conditioner that can store power through ice thermal storage. The performance of the system was evaluated considering operating efficiency and stability and the scientists found that a device relying on a variable-speed compressor and an MPPT controller showed very good ice-making capability.
First reactions to Biden’s US ban on solar imports from China’s Xinjiang province
The Biden Administration’s decision to ban solar imports from four Xinjiang-based polysilicon manufacturers has already raised concerns. One analyst warns of a “significant negative impact” across the U.S. solar industry.
‘World’s cheapest wafer’ maker plans 2 GW Indian cell and wafer fab
U.S. business 1366 Technologies is looking for Indian module manufacturing partners as it plans to bring its ‘direct wafer’ production technique to the country. The company uses molten silicon to form wafers rather than sawing ingots, thus eliminating dust waste and speeding up the process.
US government bans products from four Xinjiang-based solar manufacturers
The four manufacturers are Hoshine Silicon, Daqo, East Hope, and GCL New Energy Material.
Tigo unveils rapid shutdown device for high-power solar modules
Called Tigo TS4-A-F RSD, the device can operate with a maximum current of 15 A and a maximum voltage of 90 V. It measures 138.4 x 139.7 x 22.9mm and weighs 490g.
Trina announces first shipments of 670 W Vertex modules
The panels will be used for the first 100 MW phase of a 1 GW solar park under construction in in Dachaidan, Qinghai, western China.
New perovskite material for 23.5%-efficient solar cell
Researchers in Japan have found a new way to fabricate one of the most promising perovskite materials for PV application — the α-formamidinium lead iodide known as α-FAPbI3. With a pre-synthesized version of this material, they were able to produce a cell with a power conversion efficiency of 23.5% and a lifespan of more than 2,000 hours.
India added 1 GW of solar during Covid-hit April and May
The nation installed 1 GW of solar power capacity and 0.2 GW wind during the pandemic-hit first two months of the current fiscal year. The cumulative addition was double that of the same period during the previous year
