ECO-WORTHY Upgraded 45in Solar Panel Mount Brackets, with Foldable Tilt Legs, Suitable for 2pcs 100W/1pcs 200W 300W 400W Solar Panels,Adjustable Mounting Brackets Kits for RV, Roof, Boat, and Off-Grid

I was fortunate to snag four boxes of these for my vehicle solar. I have 4 - 400 watt residential panels on my custom conversion and wanted something to A. Help increase solar production at larger equatorial distances (the further away from the equator, the more angle you would want) and B. Help water from pooling on the flatly mounted panels when the vehicle is static for longer periods of time. Here are my observations: Pros: > Well packaged and protected hardware. > Appropriately selected and sized bolt hardware (not cheap rusting/easily bendable hardware). > Strong Angle Brackets, I was impressed at how sturdy they are. > Clear instructions which helped aid installation (my install was a bit different than some. Cons: > None so far. Recommendations: > Especially for vehicles - thread lock permanent connections to prevent loosening from vibration. > Plan out your install, I at one point accidentally installed one panel backwards not paying attention - panels should generally all tilt the same direction for most installs. > Temporarily disconnect any active arrays to avoid shock on accidental disconnect. > Plan for extra panel wire length so that as the panel rises, the wire has slack to not pull to hard.

Great sturdy solar panel mounting brackets. Easily holds large 400W solar panels! Easy to assemble, adjustable to many sun angles.

As advertised, no issues, easy to assemble, Not "heavy duty" but seems strong enough. All parts needed are supplied. It's parts, cut properly with adequate instructions and everything fits with no struggles.

This kit exceeded my expectations. High quality aluminum angle pieces, with pre - punched holes, and slots. The complete hardware kit was enclosed in the package. The included bolts are 5/16 X 1", and fit the holes in the angle pieces perfectly. Each kit also included 6 knob bolts, for easy adjustment of the panel angle. No instructions were included, but I had no difficulty in assembling the bracket kits to the panels. Lay the pieces out, next to the panel(s); and think it through, before putting the bolts in. My particular solar panels were from HQST, which required 4 mounting bolts 3/4" X 1/4". I did not mind supplying those 4 bolts, and lock nuts. I recommend this kit, and would buy it again. Update: 3-11-20 The hardware is Metric, not SAE. I think it is stainless steel, also. I found that in some configurations, it may be necessary to trim the corners off the slotted angles. to have adequate movement for use of the slots for fine adjustment. I still like the kit, and recommend it. Having checked prices for aluminum angles available locaslly, I could not find slotted aluminum angle, but what they did have locally, was pricey, confirming to me, that this kit seems to be a good value. adjustment slots

Nice light weight and strong ground mount. Worked good with my 200 watt panel. Ready to put together, would be nice if the adjustment was easier to change.

Love it

Attached this solar panel holder to a children's mattress bed frame with wheels. Bed frame cost 20 bucks at a Salvation Army type store. Then added M-D Building Products 58297 1-1/2-Inch by 1-1/2-Inch by 1/8-Inch by 72-Inch Angle sold by Amazon. Cut this 72-inch aluminum bar to size with tabs for bolt holes to keep the 41-inch arms apart. Placed the bar horizontally between the 41-inch arms on the solar panel in the middle of the Eco Flow 110w folding solar panels to make a solar panel holder for folding type solar panels. Also used; POWERTEC 71483 T-Track Knob Kit w/ 7-Star 5/16 Threaded Knob Set of 4, Black, also from Amazon to speed up install/uninstall mattress bed from solar panel holder. Used 1/4-inch threaded knobs for solar panels so I could quickly bring panels in from being, "walked away". Turned out great! Very sturdy. Disassembly time less than 2 minutes. Have to use folding solar panels because I keep them in EMP Bags when not in use. Good price, excellent quality!

Beware, will work great for a perminate install but not at all practicle for RV install. You can not easily change the angle. They are not made to be mounted flat.

Installed 2 No. 100W panels onto the mounting brackets and they work well and are easy to assemble with and operated nut and bolt. The solar panel mounting brackets are supplied with the panels. I've got the whole setup on the ground and it wobbles a bit but nothing concerning. If the brackets are fixed to something on the bottom rail it would be very solid. Very good system.

good sturdy and great for off grid RV and camping. Easy to set up and move and great for portable foldable solar blankets.

Le concept est très bon mais les cornières de mauvaise qualité et personnellement la taille n'est pas adaptée à celle de mes panneaux. Autant acheter des cornières et boulons de qualité directement en magasin.

we used it to support a box we made to house a garden hose rolled and filled with water for our solar heater for the hot tub. It is heavy, and the wheels are useful.

Trèd fragile. vendu pour de gros panneaux mais un gros coup de vent m a tordu une des barre et 2 se fendaient deja.
