I found some 167 Watt Sharp (ND-167U1T) solar panels for sale locally at a very good price. The panels measure 52.3" x 39.1"… a near perfect fit for my 53" wide GFC roof. Score! I’ll be using one of these panels to charge an EcoFlow River 2 Pro power station.
I was also looking for a convenient place to mount my Maxtrax and the roof seemed like the best spot; especially if I could place them right above the rear axle of my Gladiator so I can stand on the tires to easily access the boards.
I used extrusions and mounting brackets from 80/20 to create a mounting rack. The front and rear extrusions are 1" x 1" and the center rail is 1" x 2". The length is exactly 53". The solar panels are secured to the extrusions with 10-32 T-nuts from 80/20, and I tapped & drilled (M10x1.5) directly into the 80/20 extrusions so that the Maxtrax Mounting Pins can be screwed into them. I did have to mill counterbores in the back of the brackets to allow clearance for the 1/4" GFC T-nuts.
The total price for all of the 80/20 parts was $217 ( about ⅓ what three Beef Racks would have cost), plus about $60 for the GFC T-nuts.
