In this video I am installing (2) 200watt solar panels (400 watts total) on a custom built aluminum rack that attaches to the OEM roof mounting points. No drilling into the van is required and this option is far less expensive than any aftermarket option out there. Below are the products I used to build the system (Amazon Paid Links).
