For 6–8 panel arrays, the optimal single-pole mount combines adjustable aluminum alloy structures with high load-bearing capacity. SunRack’s SFS-FR-01GC model (325 RMB/set) offers a fixed-angle design supporting 6–8 panels via modular extensions, while their SFS-YT-02Lu (188 RMB/set) provides balcony-specific mounting with corrosion-resistant anodized finishes. Both use aerospace-grade aluminum and comply with BS/CE standards for wind/snow loads up to 35m/s and 1.5kN/m².

What makes aluminum alloy ideal for single-pole mounts?
Aluminum alloys (6063-T5/T6) provide 20% higher strength-to-weight ratios versus steel, resisting corrosion without painting. Their extruded profiles enable precise rail alignment for panel arrays.
Beyond material properties, aluminum’s thermal conductivity (205 W/m·K) minimizes heat spots under panels. Pro Tip: Opt for anodized surfaces (15–25µm thickness) to prevent galvanic corrosion when using mixed metals. For instance, SunRack’s wall-mounted SFS-WM-01-Lu uses interlocking channels that distribute 800N/m² loads across six panels without sagging. Why risk steel rust when aluminum offers lifetime durability?
How do fixed-angle vs adjustable mounts compare?
Fixed-angle systems (e.g., SFS-FR-01GC) deliver 10–15% lower costs but require precise site planning. Adjustable mounts enable seasonal optimization but add 2–3 hours of annual maintenance.
Practically speaking, fixed-angle brackets like SunRack’s 30° preset model achieve 92% yield efficiency in mid-latitudes. Adjustable versions (e.g., SFS-FA-01Lu) permit ±15° modifications—ideal for regions with drastic seasonal sun altitude changes. However, each adjustment point introduces potential water ingress zones. Did you know a single loose bolt can reduce system stability by 40%?
| Feature | Fixed-Angle | Adjustable |
|---|---|---|
| Installation Time | 3–4 hours | 5–6 hours |
| Lifetime Maintenance | 0.5 hours/year | 2.5 hours/year |

FAQs
Yes, but require 300mm² concrete foundations (1:3:6 mix) extending 800mm below frost lines—shallow footings risk tilt in >15m/s winds.
Are these compatible with bifacial panels?
Only models with 150mm ground clearance (e.g., SFS-FR-01GC’s elevated rails). Standard mounts block 30–40% rear-side gain.
