What Does the Work Involve?

Structure designed for solar load. Steel or timber frame. Glass-roofed (transparent or with built-in PV cells). Foundations to take wind and snow load. Wiring through structure to consumer unit. EV charger integration optional. Some councils require planning permission.

  • Planning rejection: Some councils refuse free-standing structures. Pre-application discussion essential.

Frequently Asked Questions

Solar carport vs rooftop solar?

Rooftop: cheaper per kW (no separate structure). Carport: works where rooftop doesn't (north-facing roof), combines with EV. Carport for EV-only optimisation.

EV charger integration?

Yes — most ideal. Charge EV with solar generated on-site. Daytime charging when sun shining.

How much electricity will it generate?

South-facing 5kW carport: ~4,000 kWh/year. Cover ~40-60% of average UK home electricity.

Will it work in winter?

Yes but reduced output. UK winter generation 20-30% of summer. Battery backup helps span low-generation periods.

Planning permission?

Usually required for free-standing structure. Lawful Development Certificate may be sufficient. Listed buildings need consent.

Best for EV owners?

Yes — combines parking, solar generation, and EV charging at once. Pairs with smart tariff for maximum benefit.
