Performance comparison of mono and polycrystalline silicon solar photovoltaic modules under tropical wet and dry climatic conditions in east-central India

Abstract This work focuses on the performance comparison of monocrystalline and polycrystalline Si solar photovoltaic (SPV) modules under tropical wet dry climatic conditions in east-central India (21.16° N 81.65° E, Raipur, Chhattisgarh). study would help to select SPV module for system installation part country. For comparative analysis, we used ratio (PR) efficiency as figures merit. The plane-of-array (POA) irradiance was determine modules. decomposition transposition models calculated POA values from measured global horizontal irradiance. data were analysed systematically 6 months non-rainy season, October 2020 March 2021. Special attention given irradiance, ambient temperature temperature—the parameters that affect PV month showed highest variation temperature. average temperatures (51–52°C) observed October–November, while lowest (34°C mono-Si 36°C poly-Si) December. value monthly (568 W/m2) February (483 results performed better than all weather conditions. maximum poly-Si panel PRs 0.89 0.86, respectively, Thermal losses higher with November, lower December due temperatures. energy yield compared PVSyst simulations.
