Abstract

The growing demand for sustainable energy solutions has elevated photovoltaic (PV) systems as a practical and environmentally viable alternative to conventional power sources in residential settings. This study presents a systematic methodology for the design and performance analysis of a grid-connected PV system tailored for a residential area, with particular emphasis on local meteorological conditions using the PVsyst simulation software. The research encompasses the interpretation of climatic data, system sizing, and performance evaluation. A detailed PV system model was developed in PVsyst to assess key performance metrics, including nominal array energy output, system losses illustrated via Sankey diagrams, effective energy at the array output, and energy delivered to the grid. The proposed system, designed with a nominal capacity of 11.3 kWp, comprises 20 JASolar photovoltaic modules and a 20 kW Huawei inverter. Simulation results indicate an annual energy yield of 20,918 kWh and an average performance ratio of 75.62%. This methodological approach provides a valuable reference for engineers and researchers aiming to adopt climate-responsive design principles for residential PV system deployment.
