    Do most people go for the full grid independence tho? I think supplemental panels make just as much sense, and utilities forbid disconnecting anyway, so it’s more like if it works it works type dealio

        tbh the shittiest part of residential solar is how unsynced it is to work, aside from like boiler, your car is gone during work, ac should be off, fridge eats like 500w at worst, you can maybe use like 5kw (and that’s what, for 30-60 minutes per day?) with boiler at best on your own, you can’t charge car cause it’s at work, and batteries explode costs. so you either go quarter-hog or full hog

            with some shenanigans and thermally massive sinks (say boilers) heating can be intermittently fed, i don’t think a lot of people (some industries might) are bothering with that for now though. (so not heat pumps but say overtly massive boiler with radiator and a fan attached to central hvac system to provide heat as needed, and heat pump as a backstop). plus winter solar efficiency by default is what 40-60%?
