Well, the deal you got is no likely longer available and probably will never be.
Also, it is totally unsustainable. The electric providers simply cannot keep paying people to produce electricity and turn a profit.
NOVEC (which the electric cooperative here) has a limit to how many megawatts of net metering generation they will allow to connect to their system.

They aren't even close to hitting the limit for residential capacity.
