Our projections for this 18-panel solar energy project indicates that this roof, which is 67% efficient when compared to a roof set perfectly south with zero shading, will still produce enough electricity to cover 64% of the homeowner’s electric bill. Better, that 64% of power will cost them a mere $0.10 per kWh over the system’s 25-year life span instead of their current ever-inflating electric rate of $0.21 per kilowatt-hour (kWh) from their utility. And perhaps most importantly, it will reduce this family’s carbon footprint by 8,200 pounds of CO2 per year, the same as taking 0.8 cars off the road.
