These aluminium mounts are an affordable alternative for mounting a single solar panel onto the roof of a small cabin or campervan when it would be un-economical to installl a full mounting array with rails and clamps.

Comes with 2 x M5.5*38mm tek screws for mounting the bracket onto a roof and 1 x M6*20mm Bolt with flange nut for securing the solar panel to the bracket.
