Ground Mount Solar

An Alternative to Roof Solar

Not all Habitat homes are appropriate for installing solar on the roof. Some are shaded by trees, neighboring buildings, or other obstructions. Some may not have a roof orientation that faces the right direction. The optimal direction is due South, but SE and SW are also acceptable.

In the case of an unacceptable roof orientation, Habitat for Humanity affiliates can consider building a simple structure to accommodate a solar system. A garden shed, picnic shelter, or carport are a few options for installing solar systems OR, if there is an adequate yard, a ground mounted system may be possible.

A Solar System has the Following Approximate Footprint

Size of Solar SystemSize Needed
3kW (7-8 solar panels)180 ft²
4kW (10-11 solar panels)240 ft²
5 kW (13-14 solar panels)300 ft²
6kW (15-16 solar panels)360 ft²

If constructing a structure that does not include walls, it is important to consider the longevity of the materials being used. Materials should be chosen according to their ability to withstand the elements for at least 25 years. Pressure treated lumber may not be adequate to achieve this longevity.
