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 are built well and out of aluminum so will last a lifetime.

These performed as advertised for pennies compared to most other systems used to install solar panels.

I’ve used these on my wood shop roof. One Cat 1 Hurricane and multiple tropical storms later, they’re still solid. Warning. Although the mounting screws have a rubber washer, I would NOT put them directly through roof sheathing alone. Guaranteed leaks in my humble opinion and likely not as solid. I first put down 1x6 PCV boards (stacked 2 high) that I screwed directly into rafters with 3” deck screws, caulked and flex sealed the leading edge. THEN attached these brackets to the PVC boards with screws provided.

Was able to attach to an all weather wood frame. Avoid all the work and cost of unistrut.

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.

Worked well, good quality

Universal fit. I've used these to mount Renology and Newpowa panels. For reasons not worth noting, I had to mount the panels on wooden frames made from pressure-treated 2x4s. Once the frame was assembled, I could just put it on a pair of sawhorses and mount the panels using these brackets. First, I firmly attached the brackets to the panels. Then I attached the panels - via the brackets - to the frame. Now they are standing up, 2 panels to a frame, against the sunny side of the garage. The brackets come with all the hardware you need.

Since they are made by Renogy, they are of course perfect for Renogy panels. Install is easy, though they need to be installed on the panels before they are screwed down to the mounting surface. Not much clearance between bottom of panel and surface when installed. For slightly curved surfaces like an RV roof, putting two on opposite sides near one end and then two on the other end (instead of the sides) enables the flat surfaces of the brackets to lay flat on the mounting surface.

These are perfect

High quality, would buy again and recommended.

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 fit all hardware included very light Cons: None

I was hesitant to purchase these, but I read the other reviews and everyone seemed happy so what the heck, I ordered 4. They are terrific, a perfect fit and well priced. They fit renogy solar panels and Coleman 100watt panels as well. I recommend them.

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.
