Renogy 4 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.

These were bought to fit my Renogy solar panels. The price is fair on these as you get all the mounting hardware you need and they are made to exact fit their panels. They are perfect for keeping the panels an inch off the roof to allow for proper air flow keeping your panels cooler.They are made of aluminum so they are nice and light. The aluminum is also ideal as you won't get the corrosion caused by using a steel bracket on an aluminum frame. The hardware included is also nice and solid.Overall, I'm very happy I got these. I could easily have saved a few bucks by making my own brackets, but the time saved and nice finished look are well worth the extra few dollars. I would highly recommend these if you have their solar panels.Pros:exact fitall hardware includedvery lightCons:None

These brackets are great for solar panels. The self tapping screws work great when mounting panels to super strut. None of the screws broke !I have ordered at least 10 or more of these kits. Would definitely order more if the need arises.

Very well thought out brackets made of quality metal. Includes all hardware for installation, No weak parts with the hardware that will need to be replaced down the road. The only downside point I would have liked to see is a few examples of how they actually attached to the solar panels. Yes, I did figure it out but not without making a couple of mistakes.

These are quite large, and heavy weight aluminium. There were other generic brands available, but I chose the Renogy set because I assumed they would be better quality. I was very happy with my decision.
