Adjustable Solar Panel Mount Mounting Rack Bracket Set Rack Folding Tilt Legs, Boat, RV, Roof Off Grid (28-inch Length)

Would these have worked straight from the box. the answer is Yes.
But,,,,As a about to retire Journeyman Toolmaker, I might not be the right person to ask to write a review about these Tilt Brackets.
One would expect these to be easily mounted by normal person with average skill, to not be cut by Burrs(razor sharp edges from machining), & to have a nicely aligned appearance when complete.
This is not the case. I had to deburr holes and sharp edges on ends of Bracket Material.
The Holes & Slots are not equidistant from the ends of the Bracket Material. I actually took the Bracket Angle Bars to work and milled the ends to achieve getting the tilting holes on the ends of the bars the same dimension to the bar ends. The mounting slots have all the room you need.
After doing this, everything mounted nice, even, & pretty.

1. The pieces all fit, and the kit was complete.
2. While the panels are held in place, I would not consider these frames to rise to the level of “sturdy.” I *do* believe they will do the job, but I wish they held the panels in place more rigidly/ firmly/solidly.
3. Case in point, the nuts and bolts appear to be quite soft metal, and I will likely need to frequently tighten them until they approach failure over time, and then I will replace them with stronger stainless/ grade 8 bolts and nuts. Not a big deal, just expect that you will need to inspect your frames and tighten them, regularly.
4. These kits ought to be priced about $29.95, not $49.95 because the cost of goods sold here was probably under $7. Six pieces of formed and drilled metal bar, various screws and nuts. The box to ship it in probably added $1.50. Now in fairness, had I made the frames myself by purchasing and drilling the frame pieces, procuring grade 8 nuts and bolts, I probably would have met or passed the $50 limit, but the frames would be strong, sturdy and durable, and NOT require me to check them once a week to see if they are still tightly fastened.
5. Since my installation, by design and need, is small and static, I had wanted to mount the panels horizontally (think landscape mode), but the panel frames are not drilled for mounting in that orientation. Not an issue for these brackets, just an FYI (Renogy 100W mono-crystalline panels).

NET: would I buy these again? probably. I will likely replace all nuts and bolts with grade 8 hardware to reduce preventative maint checks.

What it is: A mounting bracket system for solar panels.

Why I like it: I used this mounting bracket set to install a 50 watt mono-crystalline panel on the wall of my shed. The brackets are certainly sturdy enough, and the holes in the brackets lined up with the holes in my panel perfectly.

Others have complained that the brackets are very sharp. This is typical of machined parts, and easily remedied with a Dremel with a drum sander attachment or a file. It took about 10 minutes to de-burr the ends of all 6 brackets.

What I don’t like about it: The hardware is not stainless steel, so a bit of anti-seize is in order if you plan on re-positioning the panels throughout the seasons. That was probably the most disappointing aspect of the bracket set. The aluminum brackets are of high quality and can hold larger panels. For those mounting these on motor homes or boats, I would replace the wingnuts and lock washers with nylock nuts so they don’t vibrate apart. If the hardware were actually stainless steel, I would give the bracket set 4 stars.

Why you need it: Makes mounting a solar panel on a roof or wall very easy, and easy to adjust the panels for optimum sun exposure throughout the seasons.

These would get a five star rating if they had a more convenient method of tilting. Fumbling with washers and thumb screws while on your roof is no fun. I am going to retro-fit mine with clip pins on the angle pieces. The aluminum is a heavy gauge and the drilled holes are well machined, they won’t slice you up. There are enough holes and slots that you can make any tilt/ mount combination you can think of. The hardware/ thumb screws are not stainless steel, so expect them to rust after awhile. When I replace the two tilt screws with stainless pins that will be less to rust. I like the increase in distance under the panels when they are in the down position. This will help with cooling air underneath and prevent so much heat on my rubber roof as the original mounts with my panels only has around 3/4 inch from the roof, you could barely get tools under them to tighten. I did an experiment, measured the output from my panels lying flat with original mounts, clear day 11am, second week of Feb. was measuring 4.2 amps total into the converter. Next day after installing the tilting mounts, 11am clear day, now getting 11.2 amps into the convertor. I am sold on tilting. There are probably multiple reasons for the increase in power output, first is angle to the sun, the second and also important is the cooling effect of having the back of panels exposed to free circulation of air. Solar output suffers greatly when the panels are hot. Now with my semi flex panels on plastic pipe mounts, located on the ground, I can get all the morning and evening sun. I will be buying more of these mounts when I expand my battery bank and get more panels. If you had a good drill press and lots of time you could make these for half what they cost, but it is not worth my time to make my own.
