• Not sure if asking here or the van thread is best (possibly some cross over); looking to keep an out of house office/workshop warm over winter. It’s got electric, it’s well insulated but also gets full sun on the roof. Only really need a low level of heat to keep the damp/condensation out and protects the batteries/electrics etc of the things that are in there.

    Does such a thing as a solar powered storage heater exist? Or, failing that was thinking about the small space heater type things that campervans use but apart from solar panels, car battery and inverter as some of the parts have no idea if that’s feasible or realistic! Don’t want to spend a ton, would only be used in winter/when it gets properly cold to keep the temperature always above 5C ish so outright power isn’t needed, but quick, easy and mostly painless to install would be.

    Even for small loads, solar power is variable-to-useless in winter. For big loads like space heating it's not going to happen.

    Camper van heaters are diesel powered, or sometimes LPG on proper motorhomes. There's a few Youtube videos out there of people fitting diesel heaters to the outside of their sheds etc. I don't think they're particularly complicated. You just need to connect the bits in the kit and supply 12V power for the control electronics, and work out a nice way of mounting it all.

    Not solar, but there are things call greenhouse heaters. They are little electric bar rads that give of a small amount of heat to combat low temps.

    People also use them to prevent damp and condensation in sheds.

  • Lots of chat about solar and powering stuff here

    I didn't really follow it but my gut from looking at cheap heaters for home use would be that you'd get nowhere near enough power from solar without spending a lot of money.
