Enough Solar for conservative boondocking?

Hey Guys, I looked for the "Dumb Questions" thread, but didn't see it, so I'll post my question here.
I want to be able to boondock for 3-4 nights with my family of five on our 28 foot TT. I don't plan to need a lot electricity. I was thinking we would only need the furnace fan, a few lights at night, and water pump. The fridge, water heater and furnace all run on propane, so just their control panels would need some current as I understand it. I was thinking of adding a second battery, but for the same price I could get a small 50-100 watt solar panel to charge the one battery during the day. Wouldn't that be enough to keep us going based on our conservative power usage? What am I not considering?

Also, with just one small solar panel, I could just hook it directly to the battery to charge it, right? I wouldn't need a charge controller or whatever, right?
Thanks

  • Thanks for that. I am not going to do LED lights as I don't think we'll use lights enough to make a difference. I don't like the idea of worrying during the day if I'm overcharging the battery, while I'm out on a hike or something. So overcharging is a thing? Is there a charge controller or something I should put between the panel and the battery?
  • If you have LED lighting, heater fan runs less than 25% of the time through the night and none during the day, you should make it. Under the conditions you describe, a solar panel right to the battery during daytime hours should work. Keep a meter on the battery just to be sure you don't go over 14 volts just in case you didn't use much battery the first night or so.
