Abstract [en]

Different conditions such as module orientation, ground albedo, shading and latitude are known to affect the performance of bifacial photovoltaic modules. We evaluate bifacial performance for one year at a site located at 65°N through comparison of measured and simulated front and back side plane-of-array irradiation. Each investigated module has a different azimuth, tilt, and exposure to shading from the surroundings. Local shading is found to severely impact the energy yield of the site in general, and individual modules to a varying degree depending on their location and orientation. Proper shading analysis appears to be required in the planning phase of a bifacial photovoltaic installation to accurately calculate the expected energy yield. The bifacial gain of the modules with azimuths in the east–west sector is found to span a range from 16 % to approximately the bifaciality factor, depending on the orientation. To fully utilize the potential of bifacial photovoltaics, this variability also needs to be carefully considered when planning and building bifacial photovoltaic installations.
