Abstract

In this work, a double-sided solar panel (bifacial solar cell configuration) comprising of two–sided silicon PV panels was investigated. They were installed as a double solar panel that generated an electric current from both sides. 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 measured in a sunny day at noon in the mid of July in Baghdad city exactly in (July 20th, 2017). 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 & Queisser principle and Burech equation. The results revealed that the rear panel is performing better than the front panel. Despite that the backward 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.
