Solar Design Considerations

Home » Solar Toolkit: For Affiliates » Solar Design Considerations

Habitat affiliates that are interested in implementing solar on Habitat homes should take into account the following design considerations.  These recommendations will optimize the efficiency of the solar system, maximize the benefit to Habitat homeowners, and control costs.

Besides solar design considerations, Habitat affiliates are encouraged to consider “demand-side” design principles such as efficient windows and appliances, use of overhangs, passive solar, and other steps to reduce electricity demand. A good resource for these considerations can be found here.
