PENGARUH PENDINGINAN MENGGUNAKAN SIRIP TERHADAP PERFORMA PANEL SURYA

Abstract

The use of solar panels in Indonesia can be said to be quite promising, due to Indonesia's geographical location. Recorded in 2008 the earth absorbed about 1360 W/m2 irradiation from the sun. After being filtered by the earth's atmosphere, the total peak radiation absorbed by the earth reached 1000 W/m2 . When using solar panels, the power generated is influenced by several factor, especially the temperature of the solar cells themselves, because the main material of solar cells is a semiconductor material that is very sensitive to temperature. This study aims is to determine the effect of cooling using fins on the performance of solar panels. The results obtained are, in natural convection the use of fins can increase output power by 0.12% and can increase electrical efficiency from 3.31% to 3.32%. Whereas in forced convection the use of fins can increase power by 0.78% and can increase electricity efficiency from 3.38% to 3.40%. Keywords: Cooling, Efficiency, Fins, Solar Panel.
