What safety features do solar carports have?
What are the safety features of solar carports?
Solar carports in the UK incorporate multiple safety features to protect users, vehicles, and electrical systems. These structures must comply with strict national regulations, including fire safety, wind resistance, and installation standards.
Structural integrity and weather resistance
- Wind load compliance: Designed to withstand UK wind speeds (typically up to 100 mph depending on location), anchored securely to concrete foundations.
- Snow load capacity: Slope designs (e.g., 6° on premium models) prevent accumulation, while tempered glass panels handle added weight safely.
- Galvanised steel frames: Powder-coated anti-corrosion layers ensure durability in wet climates.
Fire and electrical safety
- Class-rated PV panels: Fire-resistant glass-glass modules (PREMIUM models) or framed panels meeting overhead mounting certifications.
- Isolation systems: Automatic shutdown during grid failures prevents backfeeding.
- Cable management: Conduits protect wiring from weather and physical damage.
Installation and usage safeguards
- CDM Regulation 2015 compliance: Mandates professional design/installation, including structural calculations and hazard assessments.
- Work at Height Regulations: Secure access for maintenance, edge protection, and anti-slip surfaces.
- Vehicle protection: Clear headroom (minimum 2.1m), rounded edges, and debris-resistant gutters.
UK-specific considerations
- Planning guidance: Most installations fall under permitted development if under 3m height, excluding conservation areas.
- Insurance compatibility: Structures must have MCS certification for policy validity.
- Theft prevention: Integrated security features like tamper-proof fixings (optional).
Practical advice for buyers
- Choose MCS-certified installers – Ensures compliance with BS 7671 wiring regulations and DNO notification requirements.
- Prioritise fire safety – Opt for Class A-rated panels with fire-resistant backing layers.
- Verify warranty coverage – Look for 10+ year guarantees on both structure and electrical components.
Common mistake: Assuming domestic carports don’t require structural engineering reports – essential for insurance and resale.
Recent development: Updated Building Regulations (2023) now recommend carport-integrated EV charging points, requiring improved electrical safety measures.
Pros vs cons
| Advantages | Challenges |
|---|---|
| Reduces grid reliance with solar generation | Higher upfront cost than traditional carports |
| Weather protection + energy production | Requires periodic electrical inspections |
| Increased property value | Limited design flexibility with PV integration |
For small businesses, solar carports qualify for the Super-Deduction Tax scheme (until April 2025) when installed as part of capital allowances. Homeowners may access Smart Export Guarantee payments for excess energy fed to the grid.
Example application: A Devon hotel installed a 12-space solar carport in 2023 combining EV charging and energy storage, achieving 80% self-sufficiency for its fleet.
Maintenance tip: Schedule professional inspections every 2 years for tension checks on cantilevered structures and PV performance testing.
