What do you guys have have for solar power systems for a permanent ? My head hurts when I see 400 watt systems anywhere from $ 35 to $ 2700. I'd like a 12 volt system to run camera , tv and diesel heater. For now I have a couple 12V -110 converters and I'm ok to run gen or bring batteries to shore at night once in a while when needed but looking for the biggest bang for my buck.
