Bifacial photovoltaic (PV) module can gain 30% more energy compared to monofacial if a suitable location were chosen. Iraq (a Middle East country) has variable irradiation level according its geographic coordinates, thus, the performance of PV systems differs. This paper an array (17 series, 13 parallel) was chosen produce 100 kWp for on-grid system. It investigates system in three cities (Mosu...
