Technology and R&D

The manufacturer has launched sodium-ion products online. Production has begun and will be easily scalable, according to the CATL chairman. Researchers have been keen to make the technology work as it offers a cheaper, more environmentally friendly alternative to lithium-ion products.

The PV mounting system was developed by Germany-based Goldbeck and will initially be available in the Netherlands from 2022. The company will test the new technology in a 45 MW PV project.

An Australian-Russian research group has developed a silicon heterojunction solar cell based on p-type gallium-doped wafers with an efficiency of 22.6% and an improved stability. The scientists are convinced that these wafers may become a mainstream solution for the SHJ segment within the next decade.

Sax Power has developed a new residential battery which it describes as a game-changer in the battery technology.

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.

The bifacial panel has a power output of up to 485 W and an efficiency of up to 21%. It relies on a transparent backsheet and is encapsulated with polyolefin elastomer (POE).

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 has published test results indicating the longevity of its storage systems after extended use.

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.

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.
