Solar Panel mounting bracket

Bracket that I made to mount solar panels to the rails on a pontoon boat.  My boat lists the pipe size at 1 inch but measures closer to 23 mm so the hole diameter is 23 mm.  I attached the pieces and attached panels to them with drywall screws. 3 different versions to account for different mounting issues, ultimately I used the “thin” version to mount 2 Harbor Freight 25 watt panels (one to port and one to starboard).
