Dutch company Rads Global Business has developed an anti-soiling coating for solar PV modules that is claimed to reduce cleaning cost by around 60%. The anti-reflective and anti-corrosive coating is also said to mitigate potential-induced degradation (PID).
The PV module relies on Jinko’s TOPCon mono cell technology, for which a record efficiency of 24.9% was announced last week. TÜV Rheinland has confirmed the result.
The use of polymer electrolyte membrane fuel cells as backup power generation in solar microgrids could drive down costs and improve efficiency, according to an international group of researchers. They have proposed a new energy management system that could be ideal for hybrid solar-hydrogen microgrids in remote locations.
The result was confirmed by Germany’s Institute for Solar Energy Research (ISFH).
Researchers in Finland have demonstrated the technical feasibility of an off-grid residential PV system combined with short-term battery storage and seasonal hydrogen storage. The proposed model is applicable only to northern climates, as higher levels of solar radiation in southern locations would mean a reduced need for seasonal storage. It was tested in an existing single-family house in Finland with a 21 kW rooftop array and a ground source 6 kW heat pump.
Available in four different products, the series features a conversion efficiency of 20-21.2%. Two of the panels are packaged in a sleek, all-black aesthetic.
Researchers in Norway have mapped all cropland areas that were abandoned between 1992 and 2015 and found that the vast majority is suitable for PV and bioenergy deployment. Around 30% is located in Asia, followed by the Americas, with a 28% share, and Africa, with a percentage of 22%. Europe and Oceania had shares of 20% and 5%, respectively.
Scientists in Russia have analyzed the most important technological advances achieved for solar water pumps over the past decades and have indicated the roadmap that future research should follow to expand their use and application.
