PVsyst Optimization Tool Introduction and Case Analysis on The Secondary Optimization of The Best Inclination Angle

For a fixed grid-connected photovoltaic (PV) power generation system, the selection of inclination angle should aim to maximize the annual irradiance received by the PV array's inclined surface, thereby maximizing power generation. However, if a secondary optimization of the inclination angle is performed, further improvements in power generation can be achieved, leading to enhanced overall project revenue. This paper introduces three methods for secondary optimization of the tilt angle by constructing a 3D shading model in PVsyst, which provides valuable guidance for PV project design.
