摘要

Bifacial photovoltaics (PVs) offer a promising pathway to enhancing electrical conversion efficiency and energy yield compared to standard monofacial PV systems. This study investigated the performance of a 50 kWp bifacial multi-crystalline silicon solar PV system. Simulation results indicate an annual net AC energy output of 79281.8 kWh and a net DC yield of 84763.7 kWh, corresponding to a performance ratio of 64.47 %, based on a nominal plane of array irradiance of 525330 kWh. Monthly mean inverter efficiency fluctuated between 35.62 % and 52.42 %. Subarray bifacial PV module efficiency varied from 6.98 % to 9.52 %, and cell temperature from 4.27 to 19.68 °C. To comprehensively understand system behavior, this study further analyzed monthly normalized performance indices.
