These homeowners had TFS install a solar photovoltaic (PV) system on their roof to help offset their electricity bill.  For them, going solar was a "good idea to save money."  Their favorite thing about the system is the data monitoring feature which allows them to remotely view the production of their system.  Even while on vacation, they can check on their solar energy and see how much is being produced at any point in the day.  The data monitoring also allows them to monitor solar trends and easily compare the production from one day, month or year to another.
