Detailed Review
The listing states an 8-pack of black aluminum Z brackets for 40W to 700W solar panels, with a powder-coated finish, screws, nuts, washers and instructions, plus a 24-month warranty.

How we scored them
The Solar Score weighs performance, build, value, safety and warranty. For a mount, safety means the corrosion and weather protection the listing actually states, such as anodized or powder-coated finishes and stainless hardware; a mount that states none scores lower on that line. Only the Callsun states a warranty term, and it is the only pick with a stated panel range up to 700W. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Callsun 8-Pack Z Brackets | 9.6 | 29 | 21 | 21 | 5 | 3 |
| ECO-WORTHY 16-Unit Z Brackets | 9.6 | 29 | 21 | 21 | 5 | 0 |
| IRONDIY 16-Pc Z Brackets | 9.5 | 28 | 20 | 20 | 5 | 0 |
| Spartan Power 4-Pack Z Brackets | 9.5 | 27 | 20 | 20 | 5 | 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.
How to choose the best solar panel mounts for trailer
Start from your panel’s watts and size
Two listings state a panel range. The Callsun covers 40W to 700W panels, and the IRONDIY covers 50W to 150W panels. The ECO-WORTHY and Spartan listings state no watt range, so check your panel’s dimensions against the bracket size before ordering. See our mounts, cables and connectors guides for related hardware.
Z brackets, corner kits or tilt mounts
The four main picks are Z brackets, which lift the panel slightly off the roof and suit uneven surfaces per the listings. The 2012 more-option kit uses corner and side brackets for flat roofs only, with a 0.79-inch elevation and an IP68 cable gland for the cable entry. The PFCTART more-option mount tilts from 15 to 30 degrees with extendable arms from 14 to 27 inches for seasonal angle changes. Campervan owners can compare best solar panel kit for campervan for the panel side.
Material and hardware
All four main picks are aluminum alloy. The Spartan and IRONDIY are anodized, and the ECO-WORTHY and Callsun are powder coated, all for corrosion resistance. The ECO-WORTHY includes stainless steel M6 screws, and the Spartan includes stainless steel screws, bolts and nuts. Check that the box lists every fastener you need for your roof type.
| Mount | Finish | Hardware |
|---|---|---|
| Callsun 8-Pack Z Brackets | Powder coated | Screws, nuts, washers |
| ECO-WORTHY 16-Unit Z Brackets | Powder coated | Stainless steel M6 screws |
| IRONDIY 16-Pc Z Brackets | Anodized | Not stated |
| Spartan Power 4-Pack Z Brackets | Anodized | Stainless screws, bolts, nuts |
Check the warranty line
Only the Callsun states a warranty term here: 24 months. The ECO-WORTHY, IRONDIY and Spartan listings state no term, so compare their material and hardware detail instead. For the ground-mount side of the question, see pole mount vs ground mount solar panel.
Sizing Notes
- Match the bracket count to your panels: the sets here run from 4 to 16 brackets.
- Check the stated panel watt range against your panels: 40W to 700W on the Callsun, 50W to 150W on the IRONDIY.
- Match the mount style to your roof: Z brackets suit uneven surfaces per the listings, while the corner kit is flat-roof only.
- Roof mounting is a job for a qualified installer; confirm the fasteners suit your trailer roof material.
