Impact of Solar Irradiation on the PV Panels Performances

The increase in temperature, the strong irradiation and the accumulation of dust are the famous aggressive environmental parameters that affect the electrical efficiency of photovoltaic power plants, and that influence in a direct or indirect way the durability and the reliability of photovoltaic modules. The study of the behavior of PV modules and cells in their installation environment has become essential. With their great evolution of manufacturing technology with different materials as well as their affordable investment price, photovoltaic solar panels meet several applications in different installation sites. In this work, we are interested in the simulation and the experimentation work on the effect of solar irradiation on PV panels. Also the improving of the electrical efficiency of solar panels plants through the different installation types and PV modules technology. The obtained results show that the manufacturing technology of CdTe PV modules is better compared to Si and CIS. In addition, the design of the PV plant with a solar tracking system with two axes also gives the best result compared to the fixed system and solar tracking system with vertical axis.
