This family chose to go solar because they "live in Tucson!"  Also, the SunPower lease allowed them to install a system with a single up-front payment and no future monthly payments.  Their favorite part of the new solar panels is simply "that (TFS) made it happen for us, and we never thought we could (go solar)."  The family has long been dedicated to sustainability and in addition to their solar power, they also have a cistern which allows them to harvest rainwater.
