Are Brunton solar panels waterproof?
Brunton solar panels are not completely waterproof, however they are water resistant. You do not want the box where the cables plug into the panel to get wet or submersed. Since this sits on the under side of the panels when they are laid out they are some what protected from rain or moisture while in use. The Brunton Solarflats are weatherproof as well, they are meant to be mounted and left out at all times.
