Performance Analysis of 5kWp Solar Rooftop Plant using PVsyst Software

Abstract: The present researchworkfocuses on performance of a 5kWp PV solar system, a second-generation PV technology. The Experimental PV solar system was installed at the rooftop of G.P. Convent School, located in Sankat Mochan Nagar Morar, Gwalior, M.P, India (78.21°E, 26.22°N). The research work compares the real-world performance data from 2024 with findings from the PVsyst simulation program to evaluate how closely the experimental system line up with an ideal simulated model under Madhya Pradesh climate conditions, wherethe study is conducted to evaluate the solar irradiance and compute the technical as well as economic facets of the PV solar rooftop system to supply domestic electrical energy requirements. The total yearlypower generated was6910.2kWh for experimental PV solar system and 7485kWh according to PVsyst software. The yearly global horizontal solar irradiation and diffused horizontal solar irradiation was received as 1664.6kWh/m² and 895.4kWh/m² respectively, in Gwalior, Madhya PradeshIndia. The annual average system and array losses were notes as 0.18 kWh/kWp/day for both experimental and simulated systems, therefore, additional losses were measured at 1.1kWh/kWp/day in experimental system compared to 0.84kWh/kWp/day in PVsyst model.
