In a new weekly update for pv magazine, Solcast, a DNV company, reports that areas across Mexico and Southern Texas saw reduced cloud, leading to 120-130% of average September Irradiance. Meanwhile, storms and a ‘Bomb’ cyclone caused by persistent low pressure over British Columbia delivered cloudier conditions, leading to irradiance as low as 70% of long term averages.

Battolyser Systems has improved the efficiency of its Edison battery for industrial hydrogen production. The Dutch startup said the levelized cost of hydrogen (LCOH) could be cut to €1.50 ($1.58) per kilogram by 2025. It has partnered with the European Investment Bank to support its expansion, with ambitious plans to hit 1 GW of production capacity by 2026.

US scientists have achieved a breakthrough in PV cell tech by creating a 24 cm2 perovskite-silicon tandem solar cell. It positions a lithium fluoride interlayer between a hole transport layer and the perovskite absorber to reduce shunting losses.

If 157,621 hectares of utilized agricultural area in the European Union incorporated agrivoltaics, it could produce up to 944 GW installed capacity, a new study published by the Joint Research Centre found. Despite the optimism, certain challenges – such as no clear definition and dedicated standards – stand in the way of the technology’s success.

Chinese manufacturer Atess has developed PCS1000, a 1 MW bidirectional battery inverter for commercial and industrial applications, with a 99% efficiency rating.

The German authorities have attributed the recent explosion of a 30 kWh storage battery in a private home to a likely technical defect. The incident has left the home uninhabitable, and property damages will likely be substantial, according to investigators.

A research team in China assessed the accuracy of the WRF-Solar numerical weather prediction model in simulating global and diffuse radiation. The group’s work highlighted the model’s sensitivity to aerosol optical depth, cloud optical thickness, and solar zenith angle.

A research group in Switzerland has enhanced the hail test stand to measure the impact of ice balls with larger diameters and higher speed on solar panels. The new testing approach will reportedly enable solar panel makers to assess their products with adequate safety margins.

Qcells has acquired full ownership of intellectual property rights for LECO technology with the recent acquisition of Cell Engineering. The technology is known to enhance the efficiency of PERC and TOPCon solar cells.

The French Alternative Energies and Atomic Energy Commission (CEA) has developed a recycling process for end-of-life PV modules, recovering silicon and silver, using supercritical CO2. Virginie Basini, head of CEA’s sustainable technologies department, discussed the technique with pv magazine France.
