Scientists in the Netherlands have sought to understand the reason for unexpected gains in vertical PV systems and found that these installations have a much higher heat transfer coefficient than their horizontally deployed counterparts.

Researchers in Germany have found that there is “no evidence” to support the notion that renewable energy generation fosters peace through prosperity. The trio of academics came to this conclusion after empirically testing the assumption that distributed renewable energies may reduce international conflicts and promote democratic values.

A new study from Clean Energy Associates (CEA) shows that 83% of sites tested as part of a global survey had line cracks, 78% had a soldering anomaly and 76% had complex cracks. The survey involved visual inspections combined with electroluminescence testing across 148 sites in 16 countries.

The Chinese manufacturer presented its AIKO-A-MAH72Mw, AIKO-A-MAH54Mb and AIKO-A-MAH54Mw modules at the Fintec event in Barcelona. The new products rely on the company’s all-back-contact (ABC) cell technology and feature a temperature coefficient of -0.26% per C.

The 5 kWh battery solution uses Ecoflow’s PV-coupling technology that reportedly ensures an easy connection to existing solar arrays. The new product features an output voltage range of 150-800 V.

Solax claims its new hybrid inverters can oversize PV systems by 200%, making them an ideal solution for commercial rooftop installations. There are five versions, featuring rated power outputs ranging from 15 kW to 30 kW.

Scientists in the United States 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.

The Chinese manufacturer said its new LiFePo4 battery is IP66-rated and has a lifecycle of more than 6,000 cycles. It comes with a 10-year warranty.

A group of scientists in the United States saw ‘encouraging’ results after testing the commercialisation of novel coating materials in field tests, with the coating only increasing a panel’s total cost by 1.4%.

China’s Bslbatt says its new batteries feature individual battery modules with voltages of 102.4 V and a capacity of 52 Ah. They can be stacked in series with two to seven battery modules.
