If you park under a tree or in the shade the solar will not perform as well. Why not get a folding set like these ones

I am trying to work out if I should fix the panels or get a folding set that I can move around the trailer and chase the sun. The little kits look like they are only good for charging a phone.

Interesting, but I purchased he same folding panel kit from Solar Blvd for $235.00. Unfortunately, they no longer seem to carry it.
