Solar Panels and Whole House Exhaust / by Michael Hall

DC row house where we installed solar panels. Produces about 1/3 of the power needs of this residence with a payback if 3 - 5 years. Note the whole house exhaust fan in the background - moves about 5 air exchanges in 10 minutes for the entire house - creates a great soft breeze for those warm days with cool nights in the Spring and Fall. Takes the load off the AC system with significantly less energy use.
