They plan to be on the grid at some point, there’s 4/10 of a mile through neighboring property to deal with and I’m not up and all those details. There will be a generator involved in the set up and the solar panels will not be mounted on the roof of the camper, some type of stand to keep them off the ground. The biggest issue is going to be when the camper is not occupied in below freezing temps to keep anything from freezing (like keeping the t-stat on 35-45) and having enough battery reserve to keep the fan running for what could be a couple of days between visits to the property. Obviously outside temps will play a factor in any situation, just looking for ideas on how much solar will be best, there’s room for a few more batteries as they aren’t mounted on the trailer but in a box right next to it.
