Renogy 2 Sets Solar Panel Mounting Z Brackets Lightweight Aluminum Corrosion-Free Construction for RVs, Trailers, Boats, Yachts, Wall and Other Off Gird Roof Installation, 2 Count

Made mounting the solar panels easy.

Worked perfectly for my renogy solar panels, easy to install

Being a devout DIY person I thought about making my own RV roof panel brackets. I ran out of time and got these. I'm glad I did. They would be difficult to improve upon. I used red thread locker on the single bolt joining the bracket and panel frame. I used Eternabond rubber roof repair between the brackets and the 1/8" plywood roof to cushion the contact and "level" the joint. I used plenty of Sika Sikaflex 221 on the non-sticky side of the Eternabond and the bracket and over the screws. The screws come with a silicon gasket, so the Sikaflex is just insurance. To be sure the screws got a good bite in the 1/8" plywood, I pre-drilled holes rather than trust the self-tapping screw end. I've hit 70 mph a few times since installing the panels and they are still securely fastened to the roof.

These 'Z' brackets make it easy to mount your solar panels to almost any roof. The brackets are pre-drilled to mount to the roof (2-self tapping screws) and attach to the under-side of each panel (2-bolts). I my case I don't use the hardware thats included with the brackets, here's why and how do the install. I use bytul-rolled-putty and put a piece under each bracket and scew directly to the roof (1/4" x 1.25" screws) which provides a water tight seal where the screws go into the roof. I don't want to remove this bracket from the roof to 'lift' a panel for any kind of service. Therefore, I use self-tapping screws and mount into the side/end of the solar panels. This way all I have to do is remove the self tapping screws and NOT the screws from the roof breaking the water tight seal. Yes, I lifted panels again in this installation where I tied into the wiring hidden under the panel to add 2 more panels to our truck camper roof. Another benefit of self-tapping screws, you can mount the "Z" brackets on any side/end of the panels that match with your roof structure and ease of access. The brackets are aluminum, strudy and won't rust on your roof. I'd rather see self-tapping screws provided versus the bolts supplied to attach to the bottom of the panels; then I'd give this product a 5-star rating...my opinion only.

2 Sets of Renogy Solar Panel Mounting Z Bracket...I would add that a person buff-up on mounting glue's when not attaching with screws. I know I don't want any more holes in the roof than absolutely necessary, knowledge that was learned from past experiences. Even factory roof entrances. Eventually they too will leak if not routinely maintained (which is pretty much need for success" Those big ole trailers shake and flex a lot, just ride in one for a minute (Only a 5 wheel, and follow the laws of riding in the 5th wheel while going down the road) and you, as I was, will be shocked what those trailer have to endure, also, it enlightened me how well things really need to be secured for travel. Point is, they move around so much the glue has to be very strong, durable, and durable in sunlight, and at the same time flexiable. That thinking also helps prevent tearing the panels apart, and the roof caused from being mounted toooo rigid. I try to design things of duty with a failure spot so it doesn't damage more things, things more expensive, or harder to replace, or larger parts that wouldn't have broke if it had broke somewhere else sooner. Most recent example....I brushed the fender off on a road sign after a tire blew out, and trying to gain control getting off the road....... thank goodness it easily tore the fender off and away vs tearing the fiberglass siding of the trailer off, if the fender had been to well fastened to the siding......That's just smart. Also, Experience. Original point and case, avoid putting new holes in your RV roof if at all possible. Ever had a sun roof? Moon roof? if so then you probably already know about the leak proof design..... more like leak proof for a while.... at best.

I used these for placing solar panels on top of my RV and the roof of a metal patio cover as well as other conventional surfaces like a composition roof. The ears on the brackets keep the panels in place without movement which is important when you're on the highway. The brackets are aluminum and the bolts that hold the panels to the brackets are stainless with a lock washer. The screws that screw the panels to the mounting surface seem to be some type of brass alloy and are intended for use with metal strip mounts for an array of panels. In this application they work fine. I would not use these on wood or fiberglass, such as the roof of an RV or boat. I used a coarser threaded stainless wood screw with a rubber washer and Dicor sealant for the RV. I have installed multiple panels for different uses including my house others in my family and as such have used different brackets. These are the best ones I've used.

Very appropriate. Enough to mount a panel perfectly and firmly and no rust.

Exactly whatvi needed to install my pannels, worked great.
