Solar electric systems are going in by the hundreds of thousands around the country and the globe...more than 2 gigawatts last year alone...the development of solar has been remarkable but not inside the TVA service areas even though the solar resource is much greater there than in many areas where the bulk of equipment is going...it works very well much further north than Tennessee...if you can calculate past 8-years the cost of solar is a great investment at todays prices and with 40+ year generation life with NO fuel costs to operate...!
