Performance’s improvement methods of PV solar panel by different cooling systems: A review of experimental and numerical studies

In order to enhance the performance of the PV solar panel, many studies was carried out. Several recent works of different cooling techniques using experimental and numerical methods are presented. Three materials are tested: Water, Air and Phase Change Material (PCM). PV, PVT (photovoltaic thermal) and CPV (concentrating photovoltaic) systems are cooled by passive and active cooling techniques. The effects of some structural parameters on PV cell temperature and electrical efficiency were studied and analyzed. The most important parameters are summarized on various solar irradiation, inlet air temperature, air mass flow rate, water mass flow rate, channel numbers, depth of the channel, wind speed, fins length, fins tilt, numbers of the fins, spacing between successive fins, fin thickness, container depth, Reynolds number and Prandlt number. The results showed that the photovoltaic performance enhanced when the cooling system is installed.
