New cooling modules made from warp-knitted spacer textiles for photovoltaic hybrid collectors

摘要

The production of energy using photovoltaic (PV) modules is clever and environmentally friendly, but has one inherent drawback-the efficiency of the "mini power plants" decreases if they become too hot. Therefore, when solar radiation is particularly high during the summer and there is a simultaneous increase in the ambient temperature, the efficiency of the photovoltaic system decreases - by how much will depend on the temperature coefficient. In the data sheet, this value refers to the percentage loss in efficiency for an increase in the ambient temperature of one degree.
