Longi claims world’s highest efficiency for p-type, indium-free HJT solar cells

Longi said it has achieved a 26.56% efficiency rating for a gallium-doped, p-type heterojunction solar cell and a 26.09% efficiency rating for an indium-free HJT cell, both based on M6 wafers. Germany’s Institute for Solar Energy Research in Hamelin has confirmed the results.

Growatt releases new battery for rooftop solar applications

Growatt’s new APX HV cobalt-free lithium iron phosphate (LFP) battery has a storage capacity of 5 kWh and a nominal voltage of 650 V. It can be scaled up to six battery modules, for a maximum capacity of 30 kWh, or 60 kWh in parallel. It comes with a 10-year warranty.


Rooftop system with PV panels, mini wind turbines in the Netherlands

Ibis Power has developed a rooftop system that combines solar with wind turbines designed for medium-sized structures and high-rise buildings. It claims its PowerNEST system can produce six to 10 times more energy than standalone rooftop solar. The company has already installed five projects in the Netherlands.


Polysilicon prices trending downward

PV InfoLink says polysilicon prices are clearly starting to fall. Meanwhile, Longi has lowered the prices of all wafers, and JA Solar has unveiled plans to build a new 10 GW factory.
