FlatFix Solar PV Array Spacing / Shade Calculator

The minimum required space between parallel rows to avoid shading is decided by the height of the array immediately in front, the slope of the roof and the lattitude of the installation site. The table below is only for illustration, different row spacings will be required for different panel sizes, array pitches, roof pitches and locations.

FlatFix Flat Roof: Parallel Row Spacing

Spacing illustrations are based upon mounting solar panels measuring 1675x1001x31, using two FlatFix frames secured directly to a completely flat roof (0°) in two parallel rows both facing due south. Contact us for accurate row spacing calculations for different sizes of panels and locations.
