| Abstract | ||
| Photovoltaic module (PV) performance decreases with the increase of module temperature. While, it increases with increasing solar radiation intensity. PV system is used to convert solar energy into electric power then it will be connected with a pumping system (DC motor and centrifugal pump) to run trickle irrigation system for small scale areas in Inshas. Solar panels temperature and solar radiation intensity play a big part in the photovoltaic conversion process. Since solar cells are semi-conductors, they are very sensitive to temperature. The characteristic power curve is affected significantly by the module temperature. In this paper each of voltage, module efficiency and the output power of PV module depend on solar panels temperature at different values (30º- 40º- 50ºC), solar radiation intensity ranged at (900-1000)W/m2 and PV module (Polycrystalline 240 WP). During the operation of the PV, module efficiency reached to be around 14.5% which is PV conversion efficient for solar radiation to electricity. The electrical efficiency will decrease with the increase of solar panels temperature of the PV module. | ||
