This Tucson family decided to have solar photovoltaic panels installed on their roof for environmental and sustainability reasons.  They enjoyed working with the friendly TFS installers and appreciated the good communication they held with the front office.  According to the family, one of the best parts about the system is that it allows them to save drastically on their electricity bill.  In fact, this home derives 95% of its electricity from the solar panels, and they get credit from TEP for any excess power they produce.
