I have a 20x40' area of solar panels on my shop roof, 9KW worth the airspace between the mounting and roof makes a significant drop in roof temperature. And generates 70 to 80 percent of our power for the shop and house. If I was not using the shop we would generate more power than we use at the house annually.
