Analysis of a 5.0 kWp solar rooftop system: Techno-economic, design, and simulation using pvsyst
Abstract
The paper focuses on performance of a 5.0 kWp PV solar system, a second-generation PV technology.The experimental PV solar system was installed on the rooftop of G.P. Convent School, located in Sankat Mochan Nagar Morar, Gwalior, M.P, India (78.21°E, 26.22°N).The observed data indicates that daily average energy yields for experimental solar system were 5 kWh/kWp (array yield), 6.25 kWh/kWp (reference yield), and 4.91 kWh/kWp (final yield).While PVsyst simulation estimates the slightly higher values of 5.46, 6.39, and 5.32 kWh/ kWp, respectively.The total yearly power generated was 6910.2 kWh for the experimental PV solar system and 7485 kWh according to PVsyst software.The payback period for the PV solar rooftop system ranges from between 4.57 years and 11.41 years, depending on the initial cost.The ROI ranges from 119% to 447.5%, with the system providing substantial long-term savings.Based on these outcomes, PV solar system will perform well under the meteorological conditions.
