Energy/Economic Analysis and Optimization of On-Grid Photovoltaic System Using CPSO Algorithm. Sustainability 2021, 13, 12420. https://doi.org/10.3390/su132212420.2071-1050 (online)10.3390/ su132212420https://repository.up.ac.za/handle/2263/87273Today, the use of renewable energy is increasing day by day, and this development requires the optimization of these technologies in various dimensions. Solar systems have a higher acceptance due to their high availability and accessibility; the most common solar technology is photovoltaic cell. In this research, modeling was done to achieve the most economically optimal arrangement of photovoltaic panels, inverters, and module placement to generate more electrical energy by considering economic parameters, for which the CPSO algorithm was used. Four different combinations of module and inverter were studied in this research, among which the second combination, which included PV module type one and inverter type two, was the best case. One of the significant results of the present study is 191,430 kWh of electrical energy during the studied year by the solar cell connected to the grid, which requires $42,792,727 to produce.en© 2021 by the authors.
