Impact of Solar Irradiation on the Performance Ratio of the Photovoltaic Module

Abstract

In this paper, the impact of the solar irradiation on both the average energy production of the PV system installed on the case study house and the performance ratio are studied. Both theoretical and real analysis are performed to show the impact of the solar irradiation on the energy production. The theoretical analysis is carried out by simulating the PV system in SketchUp [3] software. The real analysis is carried out on the measured instantaneous power production from one PV module installed in Kuwait Institute for Scientific Research (KISR). Based on the results the energy production is in direct proportionality to the solar irradiation while the performance ratio is in inveigle proportionality to the solar irradiation. Based on the figures that showed the deployed PV system has a maximum energy production of1150 Kwh and a minimum performance ratio of 16.5% occurs on August 2017 when the solar irradiation is 230 w/m2.
