The only reason installing residential solar makes sense is because you can sell power back to the utility.
That's not the only reason. People I know (about 10-12) that have installed solar on their residence have done so with the primary intent to reduce their electric bill. If they produce excess power and sell some back, then that makes it better. But they didn't install solar with their primary intent being to produce power and sell it back. Some months they do sell some back (typically the winter months here in FL which might be 3 months if you're lucky) and some months they just have a substantially lower bill (Typically the summer months).
