- Abstract:
- The limitation of fossil fuel sources and environmental damage caused by use of these fuels have made researches on applications of renewable energy, especially solar energy, to be an important issue in recent years. An important issue that arises in the use of photovoltaic panels is the reduction of their efficiency with increasing their temperature. By increase of a degree of Celsius, the efficiency of the photovoltaic panel decreases by 0.45%. The aim of this project is to reduce the temperature of the photovoltaic panel by using porous medium and air. The porous medium used as fins under the panel.Experimental results have shown that by using the medium placed under the photovoltaic panel and air, the temperature of the photovoltaic panel surface has decreased by 22%. Outlet air temperature has increased by 27%. Due to the fact that the relationship between the temperature of the photovoltaic panel and its output is opposite, it resulted that reducing 22% of temperature, output power of panel has increased by 5% .
