Impact on the Performance of Solar Photovoltaic System with the Innovative Cooling Techniques

The photovoltaic panel converts only some parts of solar radiation energy into electrical energy and the rest of energy will remain as heat energy, which results in raising the panel temperature and decreases electrical proficiency. The decrease in PV module efficiency depends on the assortment of limitations including temperature; the yield power diminishes by 0.2–0.5% per 1 K differs in the hotness of the photovoltaic module. The PV system efficiency could be improved by providing efficient cooling techniques like active and passing cooling system with the cooling medium air, water, phase change material (PCM), etc. This chapter summarizes the recent trends in PV cooling techniques and also discusses the impact of the innovative cooling technique on solar PV module performance by combining PCM and thermoelectric generators (TEG).
