The Solar Panel Bracket is sold as a pair and are constructed from 2.5mm thick stainless steel with a black powder-coat finish. The brackets are mounted to the rails on the roof of the tent using the laser cut mounting holes and supplied stainless steel bolts. The solar panel can be secured to the brackets using the supplied rivets through the pre-drilled holes in the bracket| you will need to drill the holes in the edge of the solar panel frame as required. The solar panel mounting brackets ensure that there is still airflow underneath the panel which helps to maintain the output efficiency of the panel.
