Ground Mount Solar Structures
Overview
What we supply
Ground mount solar structures are the fixed-tilt steel frames that carry PV modules on open land: posts, rafters, purlins and bracing on driven piles, ground screws or concrete foundations. KLY supplies the structure as a documented package — configured to the array layout, soil conditions and wind and snow actions, for utility-scale and commercial ground arrays.
A ground array is a repeating structure, so small decisions multiply: the tilt angle sets the row spacing, the soil report sets the foundation type, and the wind zone sets the post spacing and member sizes. Getting the standard details right once, then repeating them accurately across thousands of posts, is what makes a ground mount package economical.
KLY supplies fixed-tilt ranges in single-post and double-post configurations, manufactured through EN 1090-certified factories and delivered in sequenced loads that match the civils and installation programme.
Specifications
Standard ground mount ranges
Configured per project from the array layout, soil survey and Eurocode actions:
| Parameter | Standard range |
|---|---|
| Configuration | Single-post and double-post fixed-tilt rows |
| Module layout | 2–4 modules high in portrait, or stacked landscape |
| Tilt angle | 15° – 35° fixed (20° – 25° typical in the UK) |
| Foundations | Driven steel piles, ground screws, precast concrete (PHC) piles or concrete — selected from the soil survey |
| Ground clearance | 0.6 – 1.0 m at the leading edge, site-adjustable |
| Post spacing and members | Set per wind and snow zone to Eurocode actions |
Standard ranges shown — the array table, foundation type and member sizes are fixed at design stage from the site data.
Foundations
Foundation options
Selected from the soil survey and site constraints, with the interface agreed before manufacture:
Driven steel piles
Galvanised steel profiles driven directly into the ground — fast and economical where soil conditions allow, with pull-out testing to confirm design values.
Ground screws
Screwed steel foundations with minimal ground disruption — suited to variable soils and sites where removability or speed matters.
Precast concrete (PHC) piles
Precast concrete pile foundations for sites needing higher capacity or specific ground conditions — supplied with the matching post interface.
Concrete foundations
Pad or strip foundations for sites where driven or screwed options are unsuitable — including ballasted above-ground frames where penetration is not permitted.
To quote
What to send for a quotation
Drawings are welcome but not required to start. Whatever you have of the following is enough for a first quotation:
- —Site layout or array drawings — or the site location to start
- —Target capacity (MWp) or module count and module dimensions
- —Soil or geotechnical report, if available
- —Wind zone or site location for Eurocode actions
- —Preferred foundation type, if already decided
- —Required delivery window and site access constraints
Supply
Standards, documentation & supply
Structures are designed to Eurocode wind and snow actions and manufactured through EN 1090-certified factories, with capability up to EXC4 — hot-dip galvanised steel, zinc-magnesium or aluminium rails and stainless fixings. The document pack is defined at quotation, and KLY acts as principal UK importer for imported packages with DDP delivery where agreed.
See how we work for the full process and document pack, or the other solar mounting systems. These ranges are examples, not limits — if your requirement isn't covered, send it through and KLY will confirm the route.
FAQ
Ground Mount questions
Fixed tilt from 15° to 35°, with 20°–25° typical for UK sites. The tilt is fixed at design stage together with the row spacing and module layout.
It follows the soil survey: driven piles where the ground allows, ground screws for variable soils or minimal disruption, precast concrete (PHC) piles where higher capacity is needed, and concrete or ballasted options where penetration is not possible. KLY supplies the structure to suit the chosen foundation interface.
Yes. The ranges cover utility-scale and commercial arrays, with members and spacing set per wind and snow zone and deliveries sequenced in phases to the installation programme.
The package covers the structure: steelwork, purlins, clamps and routing provisions. Installation, PV modules, inverters and electrical works are carried out by your appointed contractors — and if your requirement spans wider, ask: scope is agreed per project.
Every KLY structural package is manufactured through an EN 1090-certified factory, with capability up to EXC4. Material certificates, galvanising records, inspection reports and delivery documentation come as a defined document pack.
