The 3kw PV system donated by ReVision Energy for this Habitat for Humanity home consists of 12 Q-Cell 260watt panels, and should produce around 3,100 kilowatt-hours of electricity each year. If used for heating, those 3,100 kilowatt-hours will provide the equivalent of roughly 300 gallons of oil each year, cost and carbon free, for the Umble family, for 25+ years.
