Egyptian researchers have used paraffin wax as a phase-change material (PCM) to reduce the operating temperatures of PV modules. They have found that the material improves power yield by more than 15%, compared to a reference module without cooling.Researchers at Sohag University in Egypt have developed a passive cooling system for solar panels that uses a PCM known as paraffin wax RT-42. PCMs can absorb, store and release large amounts of latent heat over a defined temperature range and have often been used, at the research level, for PV module cooling. Paraffin wax is obtained from petroleum ...Den vollständigen Artikel lesen ...
