Scientists in Austria have developed a long-term energy storage system that uses regenerative braking to adjust the descent speed of sand in mine shafts and generate electricity.

Canadian scientists have developed a new way to measure the energy yield of bifacial PV systems. They said they considered the spectral albedo of ground cover like snow and sand to predict energy gains of up to 2%, in comparison with the International Electrotechnical Commission (IEC) standard.

pv magazine Australia’s Natalie Filatoff reports on the benefits of planning vast solar project pipelines, and the barriers faced by those who dare to dream big.

Singapore-based electronics giant Flex announced that its subsidiary, Nextracker, has publicly filed a registration statement for an initial public offering.

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.
