For mounted PV systems (Installation type: Free-Standing) you can calculate the optimum<br />

row distance. This minimises mutual shading between rows of mounted modules.<br />

The suggested clearance is a function of module inclination β, position of sun γ on 21.12.<br />

at 12.00 p.m. and the mounting height h of the module.<br />

-> Proceed as follows:<br />

1. Go to the dialog Roof View > PV Area > context menu Edit PV Area. This opens the<br />

dialog Module Coverage.<br />

2. Use the feature Calculate Optimum Row Distance. This opens the Row Distance dialog.<br />
