Agricultural Land Solar
Protecting the Land Beneath the Solar Farm
Solar farms on agricultural land are approved as temporary infrastructure. The expectation is that the land returns to farming, grazing or crop rotation after 25 to 40 years. The mounting system plays a direct role in whether that actually happens cleanly.
Galvanised steel introduces a corrosion pathway into soil that FRP does not. Stainless steel avoids that pathway but at a cost premium that is difficult to justify at scale. Aluminium is poorly suited to soil contact due to galvanic corrosion risk. FRP is the only material in common use that is non-metallic, corrosion-resistant in soil, and cost-competitive.
ADAS research commissioned by the Welsh Government identifies pile corrosion and fracture as decommissioning risks that can complicate agricultural land restoration after solar projects.
Year 0 - Construction
Steel piles driven into agricultural soil. Galvanised coating intact but immediately begins interacting with moisture, pH, chlorides and sulphates.
Year 1 to 20 - Operational period
Zinc coating degrades progressively in aggressive soil conditions depending on drainage, organic content and ground chemistry.
Years 20 to 40 — Late lifecycle
Steel piles in aggressive soils may have lost significant coating protection. Fracture risk during extraction increases.
Decommissioning — Corroded piles are harder to remove
Corroded or fractured pile sections can break during extraction, delaying land restoration and increasing contractor costs.
FRP removes this pathway entirely. It does not rust, does not require galvanising and does not depend on sacrificial zinc coating protection — removing the risk at material level rather than managing it.
No rust or galvanising
Non-metallic and corrosion-resistant in soil contact applications.
Cleaner decommissioning
Supports land recovery for crop rotation, grazing or future farming.
Agrivoltaic ready
Suited to projects where agricultural activity continues beneath the array.
Built for long asset lifecycles and large-scale deployment
Utility-scale solar projects demand structural materials that perform across decades without costly intervention. FRP delivers corrosion resistance, electrical insulation and significant weight savings — all of which translate directly into lower whole-life cost at scale.
At utility scale, the weight advantage compounds. Lower handling weight reduces crane and lifting requirements, accelerates installation across large arrays and reduces ground disturbance. The non-conductive property simplifies cable management and reduces earthing complexity across large frame systems.
Ground-mounted utility-scale arrays
FRP mounting frames and support structures for large ground-mounted solar installations. Supplied to project specification and load requirements.
Coastal and corrosive environments
FRP performs where steel and aluminium struggle — salt air, high humidity and aggressive ground conditions common on coastal utility sites.
Cable management systems
FRP cable tray and management systems across the solar array. Non-conductive, corrosion-resistant and compatible with all module layouts.
Ground-mounted utility-scale arrays
No repainting, no recoating, no rust remediation. FRP removes the recurring maintenance cost associated with steel systems across a 30-plus year asset life.
