When to Consider Ground-Mounted Solar
Ground-mounted systems are ideal when roof space is limited, structurally unsuitable, or when businesses have available land. They can also achieve optimal orientation regardless of building layout.
Key Advantages
- Optimal positioning: Panels face ideal direction regardless of building
- Easier maintenance: Ground-level access simplifies cleaning and repairs
- Scalability: Systems can expand as land allows
- No roof loading: Avoids structural concerns with older buildings
Planning Requirements
Ground-mounted systems typically require planning permission:
- Systems under 0.5 hectares may qualify for permitted development
- Agricultural land may have different rules
- Green Belt and AONB locations face stricter scrutiny
- Applications typically take 8-12 weeks
Cost Comparison
| System Type | Cost per kW | Notes |
|---|---|---|
| Roof-mounted | £700-900 | Lower installation cost |
| Ground-mounted | £900-1,200 | Additional mounting and civil works |
Land Requirements
Typical space requirements:
- 50kW system: ~400 sqm
- 100kW system: ~800 sqm
- 250kW system: ~2,000 sqm
