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

I used these to mount the solar panel for the fan on my storage shed. Worked perfectly and easily. Only used three on the sloped roof. Also purchased a silicone caulking, but didn't need it with the way the foam washers in this kit worked. Nice product.

Well made…easy to install!…. A good buy!

Excellent finish and product work awesome

Solid, lightweight, and practical mounting solution for solar panel installations on RVs, boats, trailers, and off-grid rooftops. Made from corrosion-resistant aluminum, these brackets hold up well in harsh weather conditions while keeping the overall setup light. The kit includes all necessary hardware for installation, making the process straightforward even for DIYers.

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

I install these brackets ( Renogy Solar Panel Mounting Z Bracket 4 Units ) directly to the roof and so far I have not seen any issues. Note that regardless of how you try to install solar panels on your shingle type roof there are going to be some type of penetration through shingle and roof. You can install these brackets directly onto the roof; however, there are some precautions you must take to prevent leakage. You can't use the included bolts, as they are sheet metal screws. I used ¼" x 1½" steel bolts with nuts and washers. Drill the holes just big enough where you must use a wrench to drive the bolts through the roof...this way they'll be tight, which will lessen the chances of water leakage. Drive the bolts through the roof just far enough to allow a small gap between the bracket and the shingle surface. Using a caulking gun, apply roof sealant under the bracket...making sure the sealant does indeed completely covers area under the bracket. Next, drive the bolts all the way down until brackets are tight against shingles. The next step is to get inside the attic and install the washers and nuts. This task is easier with two people, one on the roof to hold or turn the bolts and one inside the attic to install and tighten the nuts, but one person can do it with a little creativity. Note that tightening the bolts/nuts will squeeze some sealant from under the bracket. Just go back on the roof and spread the sealant evenly around the brackets and around the bolt heads...the main goal is to make sure the area around bracket is completely seal. Apply as much sealant as needed to ensure everything is completely seal. I had mine installed about a week ago here in South Florida. It's been raining almost in a daily basis and so far I have not seen a leak. The one thing I can say for sure is whether or not the brackets leave enough space between the solar panel and roof for cooling purposes. Perhaps someone else here can clarify that point.

Worked well, good quality

Work great. Have had them for some time and they hold up very well.

These are perfect

Lätta och stabila fästen med skruv

Musste 2 Stück Solarmodule ( 50 W 510mmx600mm ca 5 kg Stück ) senkrecht an einer Wand montieren. Hatte zuerst geplant mir im Baumarkt einen Alu -Winkel eloxiert 40x40x2 zu besorgen . Dann zuschneiden bohren , entgraten an Solarpanel annieten usw. Mit Fahr und Wartezeiten sicher eine Aufgabe die 2-3 Stunden Zeit gekostet hätte und das Material ist ja auch nicht umsonst. Da man aber für 6,99€ auch ein Set Renogy MTS-zb Solar Panel Montage Z Halterung bekommt habe ich diesen Weg gewählt. Die Winkel sind sauber gearbeitet , ich musste nur die Wand-seitigen Befestigungslöcher aufbohren , die Winkel mit den Mitgelieferten VA ! Gewinde-schrauben an die Solarmodule montieren und die Module waren zur Wandmontage bereit. Einziger Kritikpunkt wären die mitgelieferten selbst schneidenden Blechschrauben , welche in den meisten fällen wohl nicht passend wären und außerdem nicht dauerhaft rostfrei sind. Ansonsten bin ich sehr zufrieden , hat Zeit und Arbeit gespart , sieht professionell aus , ist stabil und zumindest für kleinere Solarmodule sehr zu empfehlen .
