Study confirms rule of thumb that PV inverters should run without faults for around 15 years
A new study by Bern University of Applied Sciences shows that the performance of most PV inverters and power optimizers remains optimal for up to 15 years. The inverters considered came mainly from the manufacturers Fronius, Sputnik, and SMA and most of the power optimizers examined came from Solaredge.
New micro-inverter series from China
Beny Electric unveiled a micro-inverter series with efficiency of up to 97.5% and a European efficiency of up to 97%. The micro-inverters are available in three different versions with a rated power output of 550 VA, 700 VA, and 2,800 VA, respectively.
Huawei tops inverter supply rankings for 2021
China’s Huawei has been named the world’s biggest inverter supplier for the seventh year in a row, followed by Sungrow and Growatt, according to Wood Mackenzie.
Solar cells integrating power electronics
Researchers in the Netherlands investigated the potential for integrating power electronics in solar cells in the form of diodes, transistors, capacitors, and inductors. They believe that this kind of PV cell may initially find applications in PV-powered Internet-of-Things (IoT) devices and later, as the economy of scale kicks in, in large-scale applications.
Chinese PV Industry Brief: Almaden secures glass order from Trina Solar
