If you are actually tying the solar-panel into your house's "grid" couldn't you also make additional mods between your electrical-panel and the meter to prevent backfeed?

Or, maybe an inline battery that the solar panel tops off.

It's a solved problem because this is a feature of most hybrid inverters. The only reason it's not as easy as pie is because of lack of information, and "Scare" tactics promoted by electricity-generation companies.
