I want to build a backing for solar panels to go on a roof rack...
Am thinking that an ideal material would be unwanted plastic signs (approx 5mm thick) that the solar panels can be attached to (they are self adhesive) ??
The total area required is 1.4m x 2.0m
Can you help ?? I can collect if you do...
Or any similar material you may have that would be suitable... Thanks
Thanks
