I dont get to sell it at retail, only offset power used at night, as I called it, a free battery. The only power I can sell is excess generation at the end of the year true up. Sure, its a good deal. I added $120/mo to a 15 yr mortgage to replace $500+/mo electricity bill. $380+/mo in my pocket every month. I wouldnt tell my tax preparer to skip all the deductions, I want to pay more. Nor would I bend over to the tune of $500+ every month when I dont have to. Almost $25k in savings since installed.
Sure, its a good deal.
For you. Not for your neighbors. Often in the suburbs it's part of the "Stick it to the power company" attitude. In my rural cooperative we become informed and quickly lose that attitude.
