Self Shading

Shadow cast by PV modules onto other PV modules should be minimized in order to prevent energy production losses and hotspots development. Depending on the location and orientation of the PV plant, the tilt angle of the PV modules and the space between the module rows shall be adjusted in order to select an optimal configuration that minimizes the self-shading effect. In some of the inspected plants, the impact of the self-shading on the annual performance figures was not properly addressed during the design phase.
