These homeowners decided to purchase a photovoltaic system because of their growing concern with issues pertaining to environmental sustainability.  They love getting electricity from a  renewable energy system, which doesn’t use a fuel source, like coal, that has so many negative implications associated with it.  These East Tucson residents appreciated that the TFS staff was exceptionally friendly and took their time to educate them at every step of the way.  They said that TFS “inspired confidence in recommendation.”  This family is looking forward to researching and using more renewable energy technologies in the future.
