Solar photovoltaic producing has emerged as the leading technique of creating renewable electricity around the world. However, solar PV farms require a lot of land. Agrivoltaics has lately gained popularity since it maximizes land utilization by growing crops beneath photovoltaic panels. This article presents an economic and reliability analysis of a 6kw on-grid agryvoltaic system in Golachipa village, Patuakhali, Bangladesh's coastal region. The study replicates a system with 20 PV modules placed at Latitude-22.16N, Longitude-90.43E, using PVsyst 7.3 software and site-specific meteorological data. According to the modeling results, 9114.68 kWh of energy will be created per year, with Autumn Rice (hybrid), Winter Rice (hybrid), and Watermelon crops cultivated, with an efficiency of 0.83%. The results show that the proposed agrivoltaics system maximizes land utilization by producing crops while also producing power, with the shortest payback period, maximum profit margin, and benefit-cost ratio over the project's lifetime.
