This selling back to the grid is a ridiculous concept to begin with and the utility companies are ignorant in exploring other ways to tap into this renewal resource whether it was paid for by a homeowner or put up by the utility company. They of course are hesitant to invest in other means of providing electricity and of course are scared to death that for once their consumer base has an alternative to reducing their utility cost to minimal or even free. Personally I believe every new home built should have solar panels installed on the roof as part of the building process even if the life expectancy of the panels are only 20-30 years.
