In the modern-day period of rapidly advancing technologies heavily reliant on electricity, there has been a compulsory rise of renewable energy sources progressing swiftly and consistently. solar photovoltaic systems hold the foremost position among all renewable energy sources due to their user-friendly nature and ability to meet demand at a relatively lower cost compared to other sources. This article is centered on the unparalleled modeling of a grid-connected polycrystalline solar PV system powering an elevated metro station in Nagpur. The intricate design of the solar system is first modeled by Matlab and simulated utilizing Simulation Advisor Model software to cater to a 345-kW load. SAM software has been created to aid renewable energy users in assessing unconventional energy sources both technically and economically with ease and efficiency. A detailed analysis has been conducted concerning every aspect of the solar modules and inverters. Parametric simulation of the grid-connected solar system offers a statistical breakdown on factors such as electricity output, appropriate inverter sizing, losses, shading impacts, and economic considerations. The system design incorporates both solar and inverter models, resulting in a nominal Levelized cost of electricity of 2.4 cents/kWh, leading to a net present cost of $179,000 and a payback period of 12.3 years.
