$250 per year for replacing my lead-acid golf cart batteries ... a little gas for the generator ...
Batteries and gas annualize out to something like $40/mo for me ... without the blackouts or surges that come with grid power.
Powerwall is sold out until at least mid-2016
Right back to "theoretical", then. (It also wasn't clear that Powerwall batteries would be sold directly to end-users, so they'd only be available in expensive "officially installed" systems...)
