Owing to the low efficiency of conversion of solar energy to electrical energy, more than 80% of the incident or the striking solar energy heats the photovoltaic (PV) panel surface. This heating causes an elevated operating temperature of PV panels which is normally higher than the Standard Test Condition (STC) temperature of 25 °C. This elevated temperature of PV panel has certain damaging effects on the PV cell performance and their structures, if suitable measures are not taken to dissipate this excess heat. In a real environment, usually, this excess heat is dissipated by ambient air and natural cooling by a convective heat transfer mechanism. For this reason, the PV installations are being placed sufficiently above the ground level to provide proper airflow around the PV panel surface for their adequate cooling. This chapter presents an overview of various cooling options adopted to control the operating temperature of the solar PV panels.
