If you can generate your own electricity why bother with mining?  I thought about adding solar Panels to my home too compensate for the mining rigs, then thought why not just add more panels and sell electricity back to  the power company?  No reason to bother with a mining rig right?  turns out eh cost of a decently large solar installation, say 5Kw is a lot of money even if the tax rebate is included and the Florida incentives are added in.
