Wigan is one of Greater Manchester's largest and most underserved solar markets. With a population of over 320,000, significant new-build development around Wigan town, Leigh and Atherton, and a substantial commercial base including logistics and distribution along the M6 corridor, Wigan represents both a strong residential and commercial solar opportunity. Energy costs hit harder in post-industrial towns, making the economics of solar panels particularly compelling here.
How much solar energy does Wigan get?
Wigan sees approximately 1,340–1,360 sun hours per year — in line with the Greater Manchester average and sufficient for a productive solar installation. Being slightly west of the main Manchester conurbation, Wigan can benefit from marginally better coastal airflow than central Manchester.
A south-facing 4kW system in Wigan generates approximately 3,300–3,700 kWh per year.
| System size | Typical output (Wigan) | 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 | £1,280–£1,560 | 6–8 years |
| 6 kWp + battery | 4,950–5,550 kWh | £1,650–£2,050 | 6–8 years |
Savings based on 28p/kWh unit rate and 5.5p SEG export tariff (2026 figures).

Domestic solar in Wigan
Wigan borough's housing stock spans Victorian terraces in the town centre through to large inter-war semis in Standish and Shevington, and extensive newer estates around Hindley, Leigh and Tyldesley.
Standish, Shevington and Appley Bridge — the more prosperous northern villages — feature a high proportion of detached and large semi-detached homes ideal for 5–6kW systems.
Leigh and Atherton have significant amounts of post-war residential development with east-west oriented streets — properties here often benefit from split-array installations covering both roof slopes.
Wigan town and Ince have older Victorian and Edwardian stock where 3–4kW systems on south-facing rear roof sections deliver strong returns.
Commercial solar in Wigan
The M6 corridor through Wigan hosts a significant logistics and distribution cluster, including major warehousing operations at Wigan Investment Centre, Martland Park and Robin Park. These large flat-roof assets are ideal commercial solar candidates.
Wigan's healthcare estate (Wrightington, Wigan and Leigh NHS Trust), retail parks and the growing leisure sector also offer strong commercial solar opportunities.
- 4–6 year ROI on large logistics installations (100kWp+)
- Zero-upfront PPA available for qualifying commercial roof space
- Full capital allowances deductible in Year 1
- Strong fit for logistics, healthcare, retail and leisure

Is Wigan a good location for solar panels? Yes. With around 1,340–1,360 annual sun hours, Wigan is consistent with the Greater Manchester average — well within the productive range for modern solar panels. The financial case is particularly strong in Wigan given current energy costs in the region.
