Japan-based GBP said its new cables are complying with several international standards. It claims the cables have an antitheft function, as they should discourage copper thieves from approaching a PV system.

A research group in Finland has created a new workflow to prevent voltage rises in bifacial vertical PV systems located at high latitudes. According to their findings, vertical bifacial PV may have a 46% higher power yield compared to monofacial conventional counterparts in the Nordics, while also having an improved temporal match between PV generation and consumption.

Toyota says it will combine EneCoat’s perovskite solar cells and its own in-vehicle technologies for solar panels. Enecoat has developed a perovskite module conversion efficiency of 19.4%.

Bear Valley Solar will deploy 240 kW of a 1.5 MW cattle-sited solar field pasture this year, with the first phase of construction ramping up this summer, developer David McFeeters-Krone told pv magazine USA.

Australian renewables startup Green Gravity has teamed with underground mining contractor RUC to accelerate the commercialization of its gravitational energy storage tech.

In May 2022, PV experts from around the world convened in Germany for the third Terawatt Workshop. Almost one year later, takeaways from discussions at the workshop – combined with a wide-ranging review of research on decarbonization pathways, energy demand projections, and the state of the art in PV technology – led to the conclusion that 75 TW of installed solar capacity by 2050 was a realistic global target. More than 50 leading PV industry figures recently outlined the opportunity and the challenges that solar will face in reaching this goal.

Sofar, a China-based inverter and battery manufacturer, has introduced a new series of microinverters for balcony solar arrays and rooftop PV systems. They have a 97.5% efficiency rating and offer between 500 VA and 2,400 VA of rated power.

Oxford nanoSystems (OnS) has started working with electrolyzer manufacturers to test and scale up hydrogen production.

Scientists in the United Kingdom have investigated the durability and performance of all antireflecting coatings for solar modules and said further work is needed to improve industry standards. Their review addresses single-layer and multi-layer techniques and provides insight on their costs and viability.

The National Renewable Energy Laboratory (NREL) conducted a time-motion study and found that retrofitting roof-integrated PV requires 7% less labor than standard solar installations. For new builds, installation times fall by 44%.
