Preston is one of Lancashire's fastest-growing cities — and one of the most practical locations for solar PV investment in the North West. With a diverse mix of residential properties, significant commercial and industrial footprint around the Docks and Walton Summit, and a local authority committed to net-zero targets, Preston homeowners and businesses have every incentive to act now while 0% VAT on solar remains in place.
How much solar energy does Preston get?
Preston sees approximately 1,350 sun hours per year — very close to the UK average and more than sufficient for a productive solar installation. Being slightly inland, Preston doesn't benefit from Liverpool's coastal effect, but the difference in annual generation is modest: a well-designed south-facing system here performs comparably to most of England.
A south-facing 4kW system in Preston generates approximately 3,300–3,700 kWh per year.
| System size | Typical output (Preston) | Annual bill saving | Approx. payback |
|---|---|---|---|
| 4 kWp | 3,300–3,700 kWh | £880–£1,080 | 7–9 years |
| 6 kWp | 4,950–5,550 kWh | £1,300–£1,600 | 6–8 years |
| 6 kWp + battery | 4,950–5,550 kWh | £1,700–£2,050 | 6–8 years |
Savings based on 28p/kWh unit rate and 5.5p SEG export tariff (2026 figures).

Domestic solar in Preston
Preston's residential areas cover a wide range of property types, from Victorian terraces in Ribbleton and Plungington to larger semis and detacheds in Fulwood and Penwortham, and newer estates around Ingol and Cottam.
Fulwood and Penwortham properties tend to have larger roof footprints and good south-facing aspect — ideal for 5–6kW systems with battery storage.
Victorian terraces in the PR1 and PR2 inner-city areas are well-suited to 3–4kW systems. South-facing rear roof sections are often the productive face — we assess this during the free survey.
New-build estates around Cottam, Longridge Road and the northern fringes of the city are seeing strong uptake as residents look to offset rising energy costs from day one.
Commercial solar in Preston
Preston's commercial base includes a significant logistics, distribution and public sector footprint. Preston Docks, Walton Summit Industrial Estate and Cuerden Valley are all established commercial zones where large flat-roof and pitched-roof installations are viable.
The University of Central Lancashire (UCLan) campus and the associated supply chain of student accommodation and commercial operators around the city centre also represent strong solar candidates.
Key commercial solar facts for Preston businesses:
- 5–7 year ROI on systems from 30kWp upwards
- Zero-upfront PPA options for qualifying commercial rooftops
- 100% capital allowance on commercial solar in Year 1 under current HMRC rules
