Renogy 28in Adjustable Solar Panel Mount Brackets, with Foldable Tilt Legs on Any Flat Surface for RV, Roof, Boat, Any Off-Grid Systems

A panel mounted directly to a surface can't be adjusted. This allows you to easily change the vertical angle of a rigid panel, and help keep it perpendicular to the sun, up and down. Keeping a panel perpendicular to the sun increases panel output.My mounted panels will use 2 settings, A summer and winter setting.My location has a 50 degree difference between highest sun, Jun 21 and lowest sun, Dec 21. The middle of that 50 deg range is the middle angle between winter and summer.One panel angle setting will be midway between the shortest day of the year angle, and the middle angle. The panel gets set at that position Sept 21. The winter setting.The second panel angle will be midway between the longest day of the year angle, and the middle angle. The panel gets set at that position on Mar 21. The summer setting.At any time of the year, the panel will be within 12 1/2 degrees of the high point of the sun..These panels can be adjusted throughout the day. Just remove 4 thumbnuts, and move the tilt bracket.Put a piece of pvc pipe on the panel, and check the shadow for being perpendicular.My first one was installed several months ago. We've had 70 mph winds. No problem with a 100 watt panel. The brackets are aluminum. They will not rust. I've ordered several more since then.

These brackets are an absolute must-have for any solar enthusiast, no question. The metal is very nice, light but insanely strong, and brushed smooth and coated to prevent rust. Putting these together was really easy, all the hardware is included, it took maybe 10 minutes tops. I love that these can fit big 100 watt panels sideways, or smaller ones standing up, and bolt down to a roof, floor or even the side of a wall- anywhere you need them to go! The handy knobs make adjusting the angle very easy, though you do have to carefully screw the knobs back through the washers and hex nuts on the reverse side when doing adjustments. I tried three different angles and measured them with my voltmeter until I was sure I had the panels adjusted perfectly, the degree of angle these offer is fantastic.The only challenge I had was that one of my panels has a *very* thin frame, with almost no room for the bolts to mount it to fit. I had to hold the hex nut the bolt goes through in place underneath the frame edge with a pair of pliers, then carefully screw the bolt down through the hole into it from the top, with both washers and spacer on the top side to hold the bolt out a little so it couldn't screw down into the panel surface itself. On my panel with a decent-sized frame width it was super easy, and on the really thin-framed one still very doable, so I can't imagine this not working with virtually any panel size or type, if you are willing to make adjustments.These brackets are really necessary to get the most from your solar setup, they offer so much stability and ease of adjustment. I can't believe how long I put off getting them, now that I have them I can't imagine doing without. So useful, easy to adjust, and really excellent quality. I'll be bolting them up in a few weeks when everything else for my new installation arrives, but really these make pretty great standalone brackets too, in the meantime. I'm so pleased with these I've gone back and ordered two more- no complaints at all. A true 5-star product!!

Overall, I really like this solar panel mount. I have ordered two already. However, as others have mentioned, be prepared for missing (or extra) hardware. My first solar mount set that I received was missing a split washer and the second solar mount set had two extra bolts.

works great for 2 100 watt panels sturdy enough with little bracing

A nice stands I got six stands they're easy to put together and there strong.

My set have lasted 3 years so far without any problems.

Worked well with lots of adjustability and reasonable weight.

I’ve bought a lot of Renogy products and have been disappointed with every one. This is no different. It holds a solar panel, but it has no substantial strength for wind loading.
