Dutch scientists have developed a new algorithm to isolate shadow-related PV system malfunctions and estimate potential energy losses caused by shadowing.

New research from LUT University shows the central role of solar in Europe’s attempt to reach its 2050 zero-emissions target. It describes how photovoltaics will gradually become the characteristic element of the Old Continent’s emerging energy system by extending its use to the heat and mobility sectors.

Bslbatt has released three new hybrid inverters with nominal power ratings of 3.6 kW, 4.6 kW, and 5 kW. The line also has an efficiency rating of 98.0% and a European efficiency of 97.0%.

With AI-enabled devices able to take the money-saving efficiency of lithium batteries to an incredibly granular level, research by Inion Software shows simple changes by inverter manufacturers would enable devices of almost any age to be “smartened up.”

China’s Hanersun has unveiled its HItouch 6N module series, which is based on n-type TOPCon tech, 210 mm wafers, and half-cut cells. The monofacial and bifacial modules feature power outputs ranging from 605 W to 695 W and efficiency ratings of 21.38% to 22.37%.

UK scientists have examined the impacts of potential-induced degradation (PID) in solar cells and modules, based on a field study from a 1.2 MW PV system in Spain. Meanwhile, in a separate study, scientists in Japan have created a model for one of the less-investigated PID mechanisms, creating a model of its progress that will be useful in future research and mitigation efforts.

Scientists in Singapore have reviewed all thermal evaporation techniques for the production of perovskite solar cells and modules. Despite limitations, the new methods could lead to high production throughputs and more efficient products.

Erthos claims that with its new installation method, solar facilities could occupy just one-third of the surface covered by conventional PV plants, potentially reducing installations costs by up to 20%.

Equium has developed a new thermo-acoustic heat pump core that reportedly produces 3 kW to 4 kW of heat for every kilowatt of power it consumes. It says the refrigerant-free device could generate domestic hot water at temperatures of up to 80 C.

Chinese scientists have developed a new way to split seawater into hydrogen without using a separate desalination process. They incorporated a self-breathable waterproof membrane and a self-dampening electrolyte (SDE) into the electrolyzer, so water migrates from the seawater across the membrane to the SDE, without extra energy consumption.
