Summary

This is a quick mock up I did of a boulder 15 solar panel in order to be able to make mounts which will work with it to mount it to my roof. I'm not 100% sure its correct but it should be pretty close.

The panel is 11 by 18 and 1 inch thick

Also make sure you you check out the mounting tabs which I made for it.
