I do support the green energy and everything, but I see an important issue. You depend on the state to purchase the energy from you and the price might changed, beware of that it had happend in the past.

Another point, much more money might be made, in connection with solar pannels, on two things. First the land lots, getting a good lot that is enlighted for whole day might cost zero to nothing compared to what you can actually sell it for when someone decided to start a solar panel plant in that spot. Second is that the panels cannot be destroyed normally but must be recycled, starting a company to recylce those is actually more profitable. I have experience as I have done few legal advices in regard of those plants.
