摘要：

A remarkable characteristic of Bifacial PV is that it can capture sunlight from the front and rear surfaces. A solar radiation model of view factor based on heat transfer to distinguish the shadow area and the no-shadow area is constructed by analyzing Ray tracing irradiance. The simulation results show that when slope angle increased by about4°relative to single side solar module, the annual solar radiation can be increased to 17.41% and 28.79%, respectively, in contrast to installed in fixed inclination angle with ground reflectivity of 30% and 50%. Moreover, higher annual solar radiation can be obtained with the increase of the height of the module from the ground and row spacing. The investigation involving ground reflectivity, optimum solar radiation, height of the module from the ground and row spacing can be as a theoretical support for bifacial PV installation. © 2021, Solar Energy Periodical Office Co., Ltd.
