Spartan Power Black Solar Panel Z Bracket Mount - Lightweight Anodized Aluminum Mounting Brackets for RVs, Trailers, Vans, Campers, Boats, Walls, Roof - Set of 4

I give these a 5 Star because they are exactly what I ordered at a good price. However delivery was a day later than it was supposed to be. It was at the location very early that morning but was not loaded and delivered. It wasn't until this morning that I was notified it was delayed. I ordered this item because it said next day delivery and I needed them to finish my installation.

Worked perfectly for my use. I used these to attach a 200watt Eco-Worthy panel to my factory Roofnest Falcon 2 RTT rack. This places the panel in plane with the rack, lowering wind drag when driving. I did have to drill out the holes to make them larger so that the rack's t-channel bolts would fit through, but that was simply due to my specific application needs. These were easy to install, solid aluminum that should hold for many years to come. They easily solved a mounting issue for me, preventing me from having to custom build a solution. Definitely worth the money.

Easy to install. Came with all the hardware to install to the roof on my shed.

I thought they would be a bit flimsy from the description photo, but... They are strong and of good quality. I haven't put them in my 400watt solar panel yet... will be mounting on my backyard fence.

These z brackets are very economical compared to the adjustable angle aluminum brackets. A fraction of the cost. The only problem is, there is no adjustment. I use these on several panels facing east, where adjustments during the year wouldnt help. An expensive mounting bracket might take a year or more, to pay off the extra money, depending on panel size. I do have the more expensive adjustable brackets for easy to reach, south facing panels. Twice a year adjustment can add 10% to your total electric production. Four times a year can add 15%.

Supported a 510W solar panel on to RV roof

Perfect

Love these brackets. Lightweight but substantial enough to handle most modern panels. Excellent initial finish (black) although I expect that to fade over time; non-issue for my installation. No visible branding. Stainless steel hardware resists corrosion (unlike some others). Supplied screws/bolts worked fine for me but obviously depends on panel specs. Tough to find any negatives; will purchase again.

Worked great to attach our solar panels onto the roof of our camper van

Simple and robust. Super easy to install on my roof solar panels.
