Design and Economic Analysis of On-Grid Solar Rooftop PV System Using PVsyst Software

Abstract

Most businesses heavily rely on a consistent and reliable supply of electricity to sustain their operations. Unfortunately, the utility grid in Ghazni suffers from poor energy security, and high electricity costs. As a result, many of these establishments have resorted to using diesel generators to meet their energy demands. This study focuses on the design and economic analysis of an on-grid solar rooftop photovoltaic (PV) system, utilizing PVsyst software. The research findings indicate that the designed on-grid solar rooftop PV system has a specific solar PV capacity of 10 kilowatts, capable of generating an estimated annual energy output of 19323 kilowatt-hours. The economic analysis reveals that the system has the initial capital cost required to establish this Solar system amounts to US$ 5213 a payback period of 6.3 years and a projected ROI of 457 %.
