This makes installing solar panels a breeze! All solid hardware, none of which is rusting. Easy to assemble. Works great!

I've been using mostly z brackets for my panels so I gave these a try.This set is enough for 4 panels but they must be installed next to each other.The middle clamps is to clamp down 2 panels..I do like these better than the z brackets.They look cleaner and it seems sturdier.I like that the panels very close to each other's vs the z brackets.If you are planning on doing panels in a row, give this a try.

The included instructions are laughably incomplete but it's fairly easy to piece together what they want you to do with the parts. The manufacturer says these can be used to mount up to 4 PV panels to pitched or flat roofs of asphalt shingle, metal, or wood and they include 10 C-channel rails, 6 center clamps, 4 Z-clamps, and a bunch of self-tapping fasteners with which to do it. Everything is Aluminum except the screws, which appear to be steel so the possibility of galvanic corrosion exists even if your grounding system is good.I was skeptical that this system would be strong enough to handle the 46lb panels I needed to move from my ground mount system up to the West facing part of my workshop's roof because the panel clamps didn't seem wide enough to get a good bite on the panel frames and most wind comes from that direction. Additionally, I think 10 clamps is insufficient to adequately secure 4 panels.The manufacturer intends for you to use 2 Z-clamps at each end of the 4-panel array, with two center clamps between each panel in the row, but there is nothing to secure the bottom and top of each panel. If the center clamps loosened over time from wind, vibration, thermal expansion/contraction, or whatever, the panels could slide out of their mounts, dragging the electrical conductors with them. My panels weigh almost 50lbs, and if one got loose on my pitched roof, the results could be disastrous. This system might be adequate for flat roofs with low wind exposure, but I think they would be unsafe for any pitched situation. A minimum of 8 more Z-clamps and rails should be part of this, but 16 of each would be ideal so that each panel would have two mounting anchors on each edge. As such, I can't recommend this system for anything but totally flat, wind-protected roofs.

Summary: There are a few ways to mount solar panels to other frame structures. Z-brackets are by far the simplest version, and lowest cost. There are kits also which include short mounting rails, mainly for metal roofs, but could also be used with a wood (2x4) frame. Will be comparing a few different styles.Discussion: My pV system consists of many 100W/18V panels, and to charge my 24V battery bank, I have about half of my panels on the longer right angle mounting bars, and the larger 200W panels are just unmounted on the ground. Going to use these to attach them to wood structures / frames. While stainless steel Z-brackets would be stronger and more corrosion resistant, aluminum is the same as the frame on a typical solar panel, so the strength is sufficient, and you also don't incur the galvanic corrosion issue (dissimilar metals).Observations: MCOOH offers 1 product, not a specialty nor proven manufacturer.Pros: Complete kit and fasteners for four medium size panels; lower cost than stainless steel brackets.Cons: Non-specialty manufacturer.Conclusion: At $40, for a 4-panel kit, rating this 3-stars (non-specialty).

These solar panel mounting brackets work to mount 4 solar panels, but only all in a row. That is not a problem for me, but it doesn't make that clear in the listing. There just isn't enough hardware to place 2 rows of 2 panels.I think the hardware works good, though. Stainless steel is used for hardware and screws.

I have a few 200W solar panels and I wanted a decent method to mount them to the top of a shed in the backyard. This saved me some money since long runs of Unistrut is expensive and I didn’t really need something that big. These worked out just fine for my smaller application. The locking mechanisms hold the panels securely in place and since they are also electrically bond the panels together. This allow me to run a single ground wire to help with lightning arresting.

The top portion of the clamps which hold the panel look identical to Eco-Worthy clamps. The nut side is a simple slide style. No defects in the material or workmanship. They hold four 100W panels perfectly on a pitched roof. The self taping screws worked fine on thin metal. I had to drill some holes where the mounting interfered with the metal frame of the building. Overall this is a simple solution to mounting solar panels to a barn or well house.
