Solar Roof Rail R10 – 2.4M (2400mm) Anodized Aluminum PV Mounting Rail | Sunpal

Solar Roof Rail Profile R10 — 2.4 M (2400 mm) | Aluminum PV Mounting Rail

Build a rock-solid solar array in less time.
The Sunpal R10 Solar Roof Rail is a precision-extruded
anodized aluminum mounting rail engineered for residential and commercial
rooftop PV systems. At 2.4 meters (2400 mm), it gives installers the ideal
span for 1–2 panel widths per rail segment — reducing splice joints, saving labor hours,
and keeping your array perfectly aligned.

Why Installers Choose the R10

• ✅ Precision Extrusion — Tight tolerances (±0.2 mm) ensure clamps seat flush every time; no wobble, no rework.
• ✅ Anodized AL6005-T5 Aluminum — Marine-grade corrosion resistance rated for 25+ year outdoor service life.
• ✅ Integrated Grounding Channel — Ribbed side slot doubles as a continuous grounding path; eliminates separate grounding clips on most installs.
• ✅ Universal Clamp Compatibility — Works with all standard 30–50 mm mid clamps and end clamps (T-bolt or slide-in).
• ✅ Lightweight yet Strong — ~1.2 kg/m linear weight; supports panel loads up to 5400 Pa snow / 2400 Pa wind (per IEC 61215 test conditions when properly anchored).
• ✅ Clean Cut Ends — Factory-deburred edges protect installer hands and prevent coating damage during handling.

Quick Installation Tips

1. Plan rail spacing based on your panel width + clamp overlap (typically 20–30 mm per side).
2. Attach L-feet or roof hooks at ≤1.2 m intervals along each rail for full load compliance.
3. Use splice connectors to join rails end-to-end for arrays longer than 2.4 m.
4. Slide mid/end clamps into the top channel; torque to manufacturer spec (usually 8–12 Nm).
5. Connect grounding wire to the ribbed side channel at one end of each rail run.

Frequently Asked Questions

Q: Is this rail suitable for coastal/salty environments?
A: Yes. The AL6005-T5 anodized finish provides excellent salt-spray resistance. For extreme marine zones, we recommend pairing with stainless steel (A2-70) fasteners.

Q: Can I cut the rail to a shorter length on-site?
A: Absolutely. Use a fine-tooth metal-cutting blade or portable band saw. Deburr the cut edge with a file before installing clamps.

Q: How many panels fit on one 2.4 m rail?
A: Typically 1 landscape-oriented panel (~1.7–2.0 m wide) with room for clamps, or 2 portrait-oriented half-cuts depending on your layout.

Q: Do you offer bulk/wholesale pricing?
A: Yes — contact us for project quotes on orders of 50+ rails. Pallet shipping available.

Q: What’s the difference between R10 and other rail profiles?
A: The R10 is our mid-range profile — strong enough for most residential/commercial roofs while staying lightweight and cost-effective. Heavier profiles (R20, R30) are available for high-wind or large-format panel applications.
