The complete UK guide to ground-mounted solar installations
Ground-mounted solar panels are photovoltaic systems installed on frames or structures positioned at ground level rather than on rooftops. These installations provide a practical alternative to traditional rooftop solar, particularly for properties where roof mounting isn't optimal or feasible.
One of the key advantages of ground-mounted systems is the ability to optimise panel positioning. Unlike rooftop installations where angle and orientation are dictated by your roof's characteristics, ground-mounted arrays can be positioned at the perfect angle and oriented precisely south for maximum solar exposure. This flexibility often results in superior energy generation compared to roof-mounted systems.
Ground-mounted solar is growing rapidly in popularity across the UK, particularly among homeowners with large gardens, agricultural properties, and rural estates. These installations range from small residential systems of 3-4kW to substantial agricultural arrays exceeding 50kW. The technology suits various applications, from supplementing household electricity to providing power for farm operations or generating income through energy export.
Whether you're considering ground-mounted solar due to roof limitations, desire for optimal performance, or available land space, understanding the options, costs, and requirements is essential for making an informed decision.
North-facing, shaded, or structurally unsuitable roofs
Avoid restrictions on listed or conservation area properties
Utilise available land space effectively
Perfect for farms and rural properties
Position panels at perfect angle and orientation
Install larger systems than roof allows
The most common residential option. Panels mounted on frames secured with concrete foundations or ground screws. Cost-effective and reliable with minimal maintenance requirements.
Single pole mounting system allowing seasonal angle adjustment. Ideal for smaller gardens where space efficiency is important. Panels can be adjusted throughout the year for optimal performance.
Advanced systems that follow the sun throughout the day. Primarily used for commercial and agricultural installations. Can increase energy generation by 20-30% compared to fixed systems.
Dual-purpose structures providing vehicle shelter whilst generating solar power. Increasingly popular for homes and businesses. Combines practical shelter with renewable energy generation.
Ground-mounted solar panels typically cost 10-20% more than equivalent rooftop installations due to additional materials, foundations, and installation requirements.
| System Size | Typical Cost | Notes |
|---|---|---|
| 4kW System | £7,000-£10,000 | Small residential |
| 6kW System | £9,000-£13,000 | Medium residential |
| 10kW System | £12,000-£18,000 | Large residential |
| 50kW+ Agricultural | Quote-dependent | Commercial/farm scale |
Important: Costs include foundations, fencing where required, electrical connection to property, and DNO notification. Planning permission fees (typically £200-£400) are additional if required.
Unlike rooftop solar installations which typically fall under permitted development rights, ground-mounted solar panels usually require planning permission in England, Scotland, and Wales.
Planning applications are submitted to your local planning authority. The process typically takes 8-12 weeks, though timescales vary by council. Application fees generally range from £200-£400 depending on system size and location.
Some ground-mounted installations may not require planning permission. Standalone solar panels under 9m² may qualify as permitted development in certain circumstances. Agricultural properties may benefit from permitted development rights for farm-scale installations, though specific criteria must be met.
We recommend consulting with your installer and checking with your local planning authority before proceeding with any ground-mounted solar installation.
Ground-mounted solar installation typically takes 2-4 weeks from site survey to final commissioning, depending on planning requirements and system size.
Comprehensive site assessment and soil analysis to determine foundation requirements
Submit planning permission if required and await approval
Install concrete foundations or ground screws based on soil conditions
Construct mounting frames and install solar panels
Run cables and connect system to your property
DNO notification, system testing, and handover
Timeline Note: If planning permission is required, this typically adds 8-12 weeks to the overall timeline. The physical installation work itself usually takes 3-7 days depending on system size and site conditions.
Ground-mounted solar panels offer significant maintenance advantages over rooftop installations, making them easier and more cost-effective to maintain throughout their 25+ year lifespan.
Clean panels without scaffolding or roof access
Simple maintenance of surrounding area
Ground-level access for regular checks
Faster and more cost-effective repairs
We recommend installing fencing around ground-mounted solar arrays to prevent unauthorised access and protect your investment. Costs for appropriate fencing are typically included in professional installation quotes.
| Factor | Ground Mount | Rooftop |
|---|---|---|
| Cost | 10-20% more | Standard |
| Angle Optimisation | Optimal (30-40°) | Fixed by roof pitch |
| Planning Permission | Usually needed | Permitted development |
| Access for Maintenance | Easy ground-level | Scaffolding needed |
| Energy Generation | Higher per panel | Depends on roof |
| Space Required | Garden/land needed | Roof space only |
