No roof constraints
Ground-mount systems are not limited by roof pitch, orientation or structural load. Arrays can be positioned and angled for maximum solar yield.
Ground-mounted commercial solar systems
When roof space is limited or unsuitable, a ground-mounted solar array turns underused land into a long-term energy and income-generating asset.
The case for ground-mounted solar
Ground-mounted solar removes the limits of roof size, structure and orientation, creating room for a larger system designed around your site and energy demand.
Scalable capacity
Without roof dimensions to work around, ground-mounted systems can be scaled to exactly match your energy demand, from 50kWp to several megawatts.
Land productivity
Agrivoltaic designs allow continued agricultural activity beneath and between panel rows, your land keeps working in two ways simultaneously.
Stronger yield potential
Ground-mounted arrays can be precisely angled and oriented for maximum solar output, outperforming constrained rooftop installations on the same site.
New income stream
Surplus generation from a ground-mounted array can be sold back to the grid via the Smart Export Guarantee, turning unused land into a recurring revenue source.

Indicative system sizes and returns
Every system is bespoke, but the table below gives a guide to typical sizes, costs and returns for commercial ground-mounted solar in the UK.
| System size | Typical setting | Indicative installed cost | Illustrative annual saving | Indicative payback |
|---|---|---|---|---|
| 50–100 kWp | Farms, small commercial sites | £35,000–£75,000 | £14,000–£30,000 | 5–7 years |
| 100–250 kWp | Larger farms, estates, warehouses | £70,000–£187,500 | £28,000–£68,000 | 5–7 years |
| 250–500 kWp | Estates, manufacturing, large industrial | £175,000–£375,000 | £65,000–£135,000 | 5–8 years |
| 500 kWp+ | Large estates, multi-hectare sites | £350,000+ | £135,000+ | 5–8 years |
Figures are illustrative estimates, not quotations or guaranteed returns. They use broad UK commercial assumptions, including UK average grid electricity costs of 23p/kWh and a south-facing, unshaded ground-mounted array, and will vary with ground conditions, planning and DNO grid connection requirements, electricity tariff, on-site consumption, export value, finance and system design. A site-specific proposal will set out the assumptions used for your business. Tax treatment depends on your circumstances; seek advice from your accountant.
Is ground-mounted solar right for your site?
Ideal for
- Farms and agricultural estates with unused grassland or marginal land
- Industrial and commercial sites with limited or unsuitable roof space
- Businesses that want larger capacity than their roof allows
- Sites where roof lease or ownership is complicated
- Organisations with sustainability or net-zero land use targets
Key considerations
- Utilises otherwise dead ground
- DNO grid connection assessment required, we manage this
- Planning permission is required for all ground-mounted systems
- South or south-west facing, unshaded land produces the strongest yields
- We advise on planning, ecology surveys and any land classification requirements

Frequently asked questions
Do I need planning permission for a ground-mounted solar array?
Yes. All ground-mounted solar systems require planning permission. We manage the planning process on your behalf, including any ecological or heritage assessments.
How much land do I need for a commercial ground-mount system?
A 100kWp system requires approximately 0.5–0.75 acres of usable south-facing land. A 500kWp system requires approximately 2.5–3.5 acres. Exact land requirements depend on panel specification, mounting angle and row spacing.
Can I still use the land for farming beneath the panels?
Yes. Agrivoltaic designs are increasingly common, allowing grazing, wildflower planting or low-growing crops to continue beneath and between panel rows. This also supports biodiversity net gain requirements in planning applications.
What is the grid connection process for a ground-mounted system?
Larger ground-mounted systems require a formal connection application to your local Distribution Network Operator (DNO). Connection timescales vary from 3 to 18 months depending on local grid capacity. We submit and manage this process from the outset.
