It depends on how well you lower your electrical consumption, then you can get by for less. Sunsaver gets by on very little, but he's very frugal with every watt. Check out his blog, he talks about it on there.Pirtykitty said:How expensive is it really to go completly solar???? We live in town so not sure it its feasable .... plus don't know it the roof of our house would take it. My step son worked for a company a few years ago in Austin installing solar panels when the goverment was giving money for it.. But the work ran out... I think then he said it was at least 30 thousand.. maybe more.
