| Popis: | 31st European Photovoltaic Solar Energy Conference and Exhibition; 1764-1769 Bifacial solar cells convert photons into electricity on both their front and rear sides, which makes the assessment of solar resource trickier than for classical solar cells that are active on their front side only. Indeed, the solar irradiation received by the front side of the module is highly dependent on direct and diffuse irradiation and not to the same degree on ground-reflected irradiation. In a tilted configuration, the back side of the module hardly ever receives direct irradiation, thus increasing the importance of a good estimation of ground-reflected irradiation. A model has been developed with the Modelica language in a Dymola simulation environment in order to calculate the back-side solar irradiations received by the different modules in a PV installation. The simulation and experimental results prove that the albedo of the ground surface is of prime importance. However, the shadow of the PV installation on the ground also has a direct impact on the amount of electricity generated by the rear side. This paper assesses the relative impacts of several factors of importance in the design of a bifacial PV power plant such as elevation of structures, ground albedo, tilt angle and spacing between structures. |
