Aspiring modular solar array manufacturer Green Energy Systems has unveiled a new Australian-made prefabricated modular PV solution for large-scale applications that it says offers significant cost reductions by eliminating all stainless-steel nuts, bolts and other traditional fitments in favour of a slide-together aluminium junction system.

Longi Solar said it will invest CNY 42.5 billion ($9.4 billion) in 100 GW of wafer capacity and 50 GW of solar cell capacity in Shaanxi province, China.

Chinese manufacturer Hoymiles has developed a new line of microinverters with up to 96.7% efficiency and outputs of up to 2,000 VA. It said they can be connected with up to four high-power solar modules.

A new report by the International Energy Agency’s Photovoltaic Power Systems Programme (IEA-PVPS) estimates that lost revenue from PV module soiling amounts to more than €3 billion ($4.6 billion) per year – an amount that is only set to increase as PV systems grow larger and more efficient.

Perovskite solar cells have created excitement in recent years, given their potential to improve virtually every area of PV, but we have yet to see such devices produced at scale. Scientists in Australia have outlined some of the challenges holding them back.

For a long while, it looked as if hydrogen fuel cells would be the technology of choice for emissions-free road transport. However, truck manufacturers and freight forwarders recently turned their attention to battery-electric vehicles. This will require special charging technology and PV looks set to play an important role.

Berlin-based Boreal Light has developed water desalination tech powered by PV for off-grid applications. The solution uses 460 W solar panels from Chinese module manufacturer DAH Solar and produces clean water from direct seawater at a cost of €0.50 ($0.78)/m3.

Schneider Electric’s new Schneider Home platform includes a smartphone app to monitor and allocate energy resources.

Radovan Kopecek, the co-founder and director of Germany’s ISC Konstanz, says interdigitated back contact (IBC) tech could account for half of the global market for solar modules by 2030. He says IBC will start to dominate once TopCON and HJT get stuck at certain efficiency limits, and he believes TOPCon will be the first victim.

Trina Solar says its industrial tunnel-oxide passivated contact (i-TOPCon) solar cells, based on 210 mm wafers, have started rolling off the production line at its 8 GW factory in China. It will use the n-type cells to produce its new Vertex N modules, with power outputs ranging up to 605 W, and an efficiency rating of 22.4%.
