Seems net metering in California is sorta causing a problem . They have all this excess power during the day time around solar noon. I seen a article that one state was incentive's people getting the tesla power wall for around 1k (still the power companies) they could use it if they needed these reserves . Would be a great idea . You could buy one for your own backup . Problems require solutions that would be a good solution that benefits both you and the juice company.
