Boulder 15 Mounting Tabs

thingiverse

I used these tabs to secure my Boulder 15 solar panel to the roof of my shed. I screwed #8 screws through the roof and coated them in tar, then slipped the tabs into place under the panel out of sight. The tabs also helped push the panel down the slope of the roof to keep the screws on the underside in their slots. After attaching the tabs to the roof, I applied a layer of tar to ensure they sealed properly. Although I'm not certain what size screws the tabs are designed for, I used some that were already available in my garage and you should be able to find matching ones at Home Depot or Lowes if you want to replicate this setup.
