Abstract
A method may include calculating a solar position of the Sun and a projected solar zenith (PSZ) relative to a position of a photovoltaic (PV) module. The method may include determining whether an orientation of the PV module is configurable to prevent shading of an upper substring of the PV module while shading a lower substring of the PV module. Responsive to determining that such an orientation is not configurable, the method may include determining whether the orientation of the PV module is configurable to prevent shading of both the upper substring and the lower substring. Responsive to determining that such an orientation is not configurable, the method may include determining whether the PSZ is within a maximum tracker angle range. A target tracker angle may be identified based on the PSZ and the maximum tracker angle range and used as a tracker angle control setpoint.
