My dad was telling me that they are projected to pay for themselves in 3.5 years- and then start selling back to the grid/powering our facilites- and this is coming from the chairman- who when he asked me about going to school for environmental law called me a tree hugger- so this isnt some overhyped bs
anywho the whole company is expected to produce well over 75 megawatts of solar power by 2014 when they are all up-
heres a link to a write up on them
think of how many warehouses/massive buildings/walmarts and malls there are- I can see this taking off as more and more companies start this and prices go down
