This home produces around 7 million watts of electricity every year. If you live in the area, it is certain that some of this power was used in your home. During much of the year, we do not receive an energy bill at all. When the sun is at it's hottest, panels do not work as well (they get really hot!), and we are air conditioning. The highest electric bill this house has seen since 2013 was for $74.00 in August.
