What Is a Solar FRP Walkway?
A solar FRP (fiberglass reinforced plastic) walkway is a modular access platform designed for PV installations, constructed from resin and glass fiber reinforcement. Unlike steel or wood, it withstands outdoor harsh conditions while providing safe maintenance access. Its lightweight yet durable structure makes it ideal for rooftop and ground-mount solar farms where corrosion and roof protection are critical.
Key Benefits for Solar Applications
- Corrosion & UV Resistance: Resists rust, rot, and chemical damage—essential for long-term exposure to rain, salt, and sunlight. UV-protected variants maintain color and structural integrity without fading.
- Lightweight & Easy Installation: Weighs 1/4 of steel (11-19.5 kg/㎡ typical) for easy transport; modular design reduces labor costs by 20-40% vs. steel. No heavy lifting equipment is needed—cuts with basic tools.
- Safety Features: Non-slip gritted surface minimizes accidents in wet conditions, while insulation (withstands 10kV voltage) protects workers near electrical components.
- Cost-Efficiency: Though initial cost is 1.4-1.8x steel, zero maintenance and 5-10 year lifespan deliver 4-5x higher long-term value.
Installation & Components
– Clips: M-clips secure walkways to rails; C-clips connect adjacent panels; L-clips for edge reinforcement. Calculate M-clips as: (Total Walkway Length ÷ Grid Length) × 4.
– Rails: Parallel/vertical guides (square tube or FRP angle bar) support grating; spacing dictates thickness (e.g., 80cm spacing requires 30mm grating).
– Compatibility: Integrates with solar mounting systems using stainless steel fasteners—no damage to roof membranes.
Applications in Solar Industry
– Rooftop PV: Protects roof surfaces while enabling panel inspections; 0-60° installation angle flexibility.
– Ground-Mount Farms: Provides safe access between arrays without damaging wiring or foundations.
– Marine/Coastal Sites: Resists saltwater corrosion where steel fails.
