In the process of actually selecting the best inclination angle, factors such as the geographical environment and natural environment of the project construction site should also be considered. For example, the influence of the inclination angle on the snow sliding; the influence of the wind pressure and snow pressure resistance of the components when the inclination angle changes; at the same time, the influence of these factors on the selection of photovoltaic support materials and the foundation counterweight and the change of the distance between the front and rear rows caused by too high an angle also need to be considered , increase land cost, etc.
To compare the impact of different inclination angles on power generation, a single variable comparison should be used. However, the inclination angles of components in the same power station are generally the same angle and orientation, and there are too many influencing factors when comparing power stations in different regions. So consider using PV-System design software to demonstrate it. The meteorological data of its software comes from two meteorological databases of NASA and Meteonorm. At the same time, through actual calculations, its calculation accuracy is up to 99.3%, which is referable.
