Flat-roof photovoltaic mounting system eliminate the need for roof penetrations and ballast the photovoltaic system helps reduce home energy bills by 60 percent.
In Sacramento, Calif., home owners can generate their own electricity on cloudy and cold winter days. On sunny days, these same home owners generate nearly all the power needed to meet their home energy needs.
