Review on 🌞 BougeRV 8 Units Solar Panel Mounting Bracket Set - Optimized for RV, Roof, Boat, Off Grid - Z-Bracket Style for Secure Solar Panel Installation (2 Sets of 8 Units) by James Hova

I liked that I could attach them to the sides of the solar panel and then just screw them to the roof. They hold the panel high enough for me to install on a metal roof and clean out the ledges. I have yet to use the solar panel where I could use the long screws that come with the kit to attach the bracket to the panel (hence the 4 stars) - I used some small short sheet metal screws I already had.
