The panels are ready, the roof is waiting, and the choice of what holds them up matters as much as the watts. That mounting choice is what aluminum vs stainless steel solar panel mount comes down to. The short verdict: pick the aluminum side for panel mounting itself, like the Oungy tilt brackets for flat roofs, RVs and boats, or the Anbte end clamps for unistrut and metal roofs. Pick the stainless steel side for small panels and cameras on gutters, like the WiTi no-drill gutter mount. We compared the three listings on fit, materials, installation and stated terms.

Specifications are manufacturer rated as listed, collected 22 October 2026.
Fit and adjustment
The aluminum side mounts full panels. The Oungy states adjustable tilt brackets for panels from 50W to 400W, with a 15-30 degree tilt and arms that extend from 14 to 27 inches, for flat roofs, RVs, boats, garage floors and sturdy walls. The kit includes 2 bases with extendable arms, L-brackets, swivel brackets, screws and pads, with stainless steel screws to attach to the panel’s existing mounting holes. The Anbte states 10 end clamps for standard unistrut in black aluminum alloy, with a two-hole design: the shorter side for 30 mm (1.18 inch) panel thickness and the longer side for 35 mm (1.38 inch) thickness, including groove nuts and M8x44mm screws plus a wrench. The stainless steel side mounts small gear: the WiTi is a no-drill gutter mount with a 1/4″-20 thread for Wyze, Eufy and Arlo cameras, solar panels and LEDs on standard rain gutters.
Materials and corrosion
Both sides claim corrosion resistance in different words. The Oungy states corrosion-resistant aluminum alloy, lightweight and durable, that withstands outdoor weather for seasonal or permanent installs. The Anbte states aluminum alloy brackets with light weight, large load capacity and strong corrosion resistance, with mounting screws in 304 stainless steel for rust resistance, powder coated black. The WiTi states an all stainless steel mount and butterfly screws that are anti-rust and rust-resistant for various weather conditions, polished silver, at 0.2 kg and 2.99 by 2.36 by 1.26 inches.
What the listings leave unclear
The Anbte spec table lists Material Type as aluminum, carbon steel and stainless steel together, so the bracket body and the hardware are mixed in one field. The WiTi title names cameras and LED devices alongside solar panels, so it is a small-device mount rather than a panel array mount. The Oungy title lists panel sizes up to 400W while the spec table gives a 400 watts maximum power; the two agree. None of the three listings states a warranty term, and none states a wind or snow load figure.

How we scored them
The Solar Score weighs performance, build, value, safety and warranty. For mounts, safety means stated certifications or protection features the listing names; none of the three states any, so the safety line is empty for all. None of the three states a warranty term either. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Oungy tilt mount brackets | 9.5 | 30 | 21 | 21 | 0 | 0 |

| WiTi gutter mount stainless | 9.4 | 28 | 20 | 19 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
aluminum vs stainless steel solar panel mount: which should you choose?
Choose aluminum when the job is mounting panels. The Oungy suits flat roofs, RVs and boats with adjustable tilt for 50-400W panels; the Anbte suits unistrut and metal, tin, flat and sheet roofs with its 10 clamp kit. Choose stainless steel when the job is a gutter: the WiTi suits small solar panels and cameras with no drilling.
