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.

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.

Researchers recently identified the optimal laser energy for crafting BFO/WO3 bilayer thin films for solar cells at 200 millijoules (mJ), by carefully considering factors such as leakage and band gap.

ENEA and Enel have developed an ‘algovoltaic’ system to cultivate high-value microalgae, ranging from €100 ($106.19)/kg to €600/kg for pharmaceutical uses or cosmetic purposes. This is possible due to the integration of a fully automated cultivation system with a 7 kW solar array.

Scientists in Spain tested PV modules under partial shading conditions, aiming to better understand the formation of performance-damaging hotspots. The study reveals a potential issue particularly affecting half-cell and bifacial modules, which may cause accelerated performance loss and is not covered by current testing/certification standards.

Mibet has developed a new solar carport with a waterproof design, allowing the deployment of framed and unframed solar panels with tilt angles ranging from 5 degrees to 15 degrees, in either portrait or landscape configurations.

Panasonic and Reclaim Energy have partnered to develop a new heat-pump hot water system for the Australian market. They claim that it is up to five times more efficient than gas or traditional electric heating.
