Renogy4 Sets of Solar Panel Mounting Z Brackets Lightweight Aluminum Corrosion-Free Construction for RVs, Trailers, Boats, Yachts, Wall and Other Off Gird Roof Installation, 4 Count

These might not be the cheapest set you'll find, but they are sturdy and comprehensive. They appear to be corrosion-resistant, which is definitely needed for outdoor panels.Most impressive was that they came with real roofing screws and a sealant. If you are looking to install your panels on a roof, here's how you do it: install the brackets on your panels FIRST and tighten them well. Then put the whole panel on the roof and screw them in place. Unscrew them and squeeze in the sealant, then screw them back in tightly. This will give you a water-tight seal.

The brackets are working well as Renogy solar panel brackets after 4 years on the van roof
