holy shit, mine was $15 here in Australia so that’s about 50c in US dollars (some sarcasm) AND that includes charging my ecar. i have 8.4kW of solar on the roof and I get paid a grid feed in tariff for the extra kW I don’t use. We are conscious about doing electric intensive things when the suns shining though eg oven for baking, charging the ecar and ebikes, hot water on from 11-5 only etc
