I have an idea of where you are I think from the temps…. There’s a guy in northern Canada, sells a solar charger kit, wonderful wacky autistic bastard, lives totally on solar. Uses it to heat, and hot water too. Stores the excess as a thermal mass. He ran the number and it’s literally cheaper to do photovoltaic panels ( a ton) than it is to do other methods. Also, panels are cheap. Used $50 each, new $150. With low light high latitude you just over panel by a factor. Double , triple… int he summer you can use the wild excess to run a hot tub.
