Simulation and Analysis of Losses by Degradation in Photovoltaic Energy Production System
Main Article Content
Abstract
Currently several technologies are being developed to produce electricity from renewable sources, and the degrees of maturity, performance and lifetime are very different from one technology to another. This work presents a study by a simulation and analysis for clarity the effect of aging of a photovoltaic module associated with an energy production system of renewable origin installed in a desert environment. The PV array has a nominal power of 9,2KWp, and the photovoltaic module used in this study is heterojunction with intrinsic thin layer technology of 230WP. During this work, we obtained the system production is 17131 KWh/year, the producible is 1862 KWh/KWp/year, and the normalized production is 5,10 KWh/KWp/day, with the losses of the system is 0,16KWh/KWp/day. The performance ratio of our simulated system is about 0,822, and the collection loss of the photovoltaic field is LC = 0,94KWh/KWP/day, with loss system is LS = 0,16 KWh/KWP/day, and the aging rate of photovoltaic module estimated by simulation around the 14% for 25 years of electrical production in a desert environment.
