Southport is one of the North West's best-kept secrets for solar energy. Its position on the Irish Sea coast north of Liverpool gives it some of the highest annual sun hours in the region — comparable to Blackpool and significantly above the national average. The town's substantial Edwardian and Victorian detached housing stock, popular retirement demographic, and growing new-build zones around Birkdale and Churchtown all make it an excellent solar market.
How much solar energy does Southport get?
Southport sees approximately 1,410–1,440 sun hours per year — among the best figures in the North West, benefiting directly from its unobstructed coastal aspect. Lying on the flat Lancashire coast north of Liverpool, it experiences the same irradiance uplift that makes Blackpool and Liverpool among the most productive solar locations in the region.
A south-facing 4kW system in Southport generates approximately 3,550–4,000 kWh per year.
| System size | Typical output (Southport) | Annual bill saving | Approx. payback |
|---|---|---|---|
| 4 kWp | 3,550–4,000 kWh | £960–£1,200 | 6–8 years |
| 6 kWp | 5,325–6,000 kWh | £1,450–£1,750 | 5–7 years |
| 6 kWp + battery | 5,325–6,000 kWh | £1,850–£2,250 | 5–7 years |
Savings based on 28p/kWh unit rate and 5.5p SEG export tariff (2026 figures).

Domestic solar in Southport
Southport's housing character is distinct from most of Merseyside. Its Edwardian and Victorian streetscapes — particularly around Lord Street, Birkdale and Ainsdale — feature substantial detached and semi-detached properties with large, well-pitched roof sections. These are some of the most productive domestic solar sites in the North West.
Birkdale and Ainsdale (PR8) feature large Edwardian detacheds with generous south-facing roof areas. Many accommodate 6–8kWp systems.
Churchtown (PR9) has traditional cottage and semi-detached properties, well-suited to 4–5kW installations.
Crossens and Banks — the rural northern fringe — have detached properties with large unshaded roof areas, ideal for premium solar installations.
Southport town centre properties near Lord Street include flat-conversion opportunities and commercial roof space above retail.
Commercial solar in Southport
Southport's economy is heavily weighted to tourism, hospitality and retail. The town has significant hotel, guesthouse and care home stock along the seafront and in the inner suburbs — sectors where daytime electricity consumption aligns strongly with solar generation hours.
The Plaza Shopping Centre and surrounding retail park, and the Southport Business Park, also offer commercial solar opportunities.
- 5–7 year ROI on 30kWp+ commercial systems
- Zero-upfront PPA for qualifying hospitality and commercial properties
- Full capital allowances in Year 1

FAQs — solar panels in Southport
Is Southport's sea air a problem for solar panels? Not at all. Modern IP67-rated solar panels are fully weatherproof and resistant to coastal salt air. Southport's coastal position is a significant advantage for solar irradiance — more sunlight hours than inland equivalents.
What's the best system for a large Birkdale or Ainsdale property? Large Edwardian detacheds in PR8 typically accommodate 6–8kWp with battery storage — some with 10kW+ on particularly large roofs. Annual savings for a 6kW + battery system run £1,850–£2,250 at current energy prices.
Does Southport get a lot of sunshine? More than most people realise. Southport's coastal position on the Irish Sea gives it approximately 1,410–1,440 sun hours per year — comparable to Blackpool and better than most of Greater Manchester. It's one of the sunniest locations in the North West.
Can Southport guesthouses and hotels get commercial solar? Yes — the hotel and guesthouse sector in Southport is among the strongest commercial solar markets we serve. Daytime electricity consumption (laundry, catering, common areas) aligns with peak solar generation. We offer PPA financing at zero upfront cost.
Southport electricity costs and solar yield
Southport takes its supply from SP Energy Networks Merseyside, with a Q3 2026 capped unit rate of around 25p. The Sefton coast is one of the sunnier corners of the North West at roughly 1,020 kWh/m² annually, thanks to a flat landscape and an unobstructed westerly aspect. Sefton Council has declared a climate emergency with a 2030 borough target, and Warm Homes Local Grant assessments cover PR8 and PR9 households on qualifying benefits or in poorly rated properties.
