‘Polysilicon shortage will continue through 2021’
The latest global PV industry outlook published by trade group SolarPower Europe, has indicated tight supply of the solar panel raw material is expected to persist this year but the trade body said it would be unlikely to drive further price rises.
Sunseap announces 2.2 GW floating PV project at Indonesian water reservoir
If built, the project would be the world’s largest floating PV power plant and would reach the same capacity as the largest ground-mounted facility currently in operation.
Longi claims 25.19% efficiency for p-type TOPCon solar cell
Longi’s 25.19% efficiency rating for its new p-type TOPCon solar cells, confirmed by the Institute for Solar Energy Research in Hamelin, is reportedly a world record.

Micro-inverter for balcony solar modules
Two different devices designed by German manufacturer Bosswerk can feed up to 300 or 600 watts into the home network. The company offers a 12-year guarantee.
Sonnen battery still running after 28,000 full charge cycles
Sonnen has published test results indicating the longevity of its storage systems after extended use.
Portable hydrogen fuel cell generator with power output of 400 W
The generator can be combined with batteries, solar panels, or small wind turbines. It is based on a proton exchange membrane fuel cell technology and is claimed to have a minimum lifetime of 5,000 working hours.
Solar module cooling techniques for the desert
Saudi scientists have tested several cooling technologies for solar panels and have found that active techniques work better than passive ones under harsh climatic conditions. The most effective one consists of a system based on four heat pipes immersed in a box of liquid, as liquid bulk, integrated with the back of the solar panel.
JinkoSolar claims 23.53% efficiency for n-type, TOPCon, monocrystalline panel
The PV module relies on Jinko’s TOPCon mono cell technology, for which a record efficiency of 25.25% was announced in late May. TÜV Rheinland has confirmed the result.
