In this work, a double-sided solar panel (bifacial solar cell configuration) comprising of two silicon PV panels attached back-to-back was investigated. The module was fixed on an adjustable ground mounted frame and the tilt angle was varied to be (30º, 45º, 60º, and 90º). For each angle, temperature and irradiance were monitored in a sunny day at noon in the mid of July in Baghdad city. The photovoltaic performance of each individual panel shows a remarkable variation with tilt angle which attributed to the impact of irradiance and surface temperature of each panel. This impact was anticipated based on Shockley and Queisser principle and Burech equation. The results revealed that the rear panel is performing better than the front panel. Despite that the rear panel was exposed to a lower illumination, it supplied higher power conversion efficiency than this of the front panel except for the case of 90º tilt angle. Bifacial characteristics were studied on the bases of series and parallel connections. The series connection produced lower gain in power than that of the parallel connection.
