The Chinese manufacturer said Germany’s TÜV SUD has confirmed the results.

Maxeon said its new Sunpower Performance 7 panel series features a power conversion efficiency of up to 22.7% and an operating temperature coefficient of -0.29% C.

A team of scientists in Australia claim to have achieved the highest efficiency reported to date for a perovskite-CIGS tandem solar cell built on a flexible steel substrate. In the proposed cell configuration, steel can act as both a substrate and an electrode.

Maxeon said it has achieved a 24.9% efficiency rating for a full-scale Maxeon 7 solar panel using its IBC technology. The US National Renewable Energy Laboratory (NREL) confirmed the result.

Chinese manufacturer JinkoSolar says its solar module shipments reached 78.5 GW in 2023. This year, it says it hopes to sell up to 110 GW of panels.

The new panel has a white backsheet and a temperature coefficient of -0.34/C. It weighs 4.1 kg per m2 and, according to the manufacturer, supports all types of installation methods, including roof adhesive and removal mechanical mounting.

The International Renewable Energy Agency (IRENA) released a new report on the sidelines of the Berlin Energy Transition Dialogue this week describing the actions needed so the world complies with targets set at the recent COP28 conference in the United Arab Emirates. IRENA President Francesco La Camera says renewables are the only energy sources with the speed and scale to achieve the ambitious targets set in Dubai.

Chinese manufacturer DAH Solar says its new double-glass panels have a power conversion efficiency of 22.65% and a power output of up to 585 W.

A unit of French construction group Vinci has developed a new tool to ensure efficient earthworks for ground-mounted PV systems, with a focus on optimization parameters, design restrictions, allowable slopes for mounting structures, and terrain adaptation.

Chinese storage system manufacturer Bslbatt says its new batteries feature individual battery modules with voltages of 80 V to 1,000 V and a capacity of 135 Ah. They can be stacked in series with up to 10 battery modules.
