Sunlight in Leigh, in numbers

Our GB average is 925 kWh per kWp a year, the mean of the 85 county PVGIS estimates we publish; at 926, Leigh is level with it.
How Leigh compares
Among the places we publish figures for, Leigh is one of 109 Lancashire towns we track, and it ranks 43rd of 109 for solar yield. It is a medium town in the House of Commons Library classification, with 49,673 residents, and its roofs see 2.54 peak sun hours a day across the year. That drives the standard 12 panel model to 5,889 kWh of generation, of which around 4,953 kWh is exported at 12p for £594 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Leigh's own yield, and prices a 12 panel system at £6,360 installed before any battery. Your free design call reworks every number for your actual roof, its shading and your usage.
Any planning application in Leigh sits with Wigan, and its official House of Commons Library settlement class is medium town.
The charger is in the installed price but left out of payback: charging savings depend on your mileage and tariff, which the design call models properly.

The network operator for Leigh
On NESO's licence-area map, Leigh is in North West England, which Electricity North West operates. That makes Electricity North West the network operator for any system fitted here.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to Electricity North West within 28 days of commissioning, with no prior approval.
Larger systems go through G99 instead, applied for before installation. On timing: Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds Electricity North West as it does every network operator.

Heat pumps and EV charging in Leigh
A heat pump in Leigh
In January, the darkest month here, 12 panels in Leigh make about 180 kWh. That is when a heat pump runs hardest, so its running cost in Leigh comes down to the tariff and the flow temperature rather than the roof.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Leigh
Summer is where a car earns its place. In May, 12 panels in Leigh make about 760 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Solar in Leigh: your questions answered
How much electricity do solar panels make in Leigh?
About 5,890 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Leigh: 926 kWh per kWp, or 2.54 peak sun hours a day on average. May is the strongest month, at about 760 kWh.
What does a typical solar system cost in Leigh?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Leigh, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 5,890 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Leigh, and what does it need from me?
Electricity North West covers Leigh. A home system of up to 3.68kW per phase is notified to Electricity North West within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds Electricity North West as it does every network operator.
What happens to the solar I do not use in Leigh?
Around £594 a year at 12p per kWh, for the roughly 4,953 kWh a 12-panel system in Leigh exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Leigh get in December?
December is the low point: about 180 kWh from a 12-panel system in Leigh, on PVGIS data, rising to 760 kWh in May. From November to February the same system makes about 920 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Leigh compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Leigh.
| Town | kWh per kWp a year | vs Leigh |
|---|---|---|
| Leigh | 926 | this town |
| Atherton | 923 | −3 kWh |
| Tyldesley | 923 | −3 kWh |
| Golborne | 929 | +3 kWh |
| Hindley | 930 | +4 kWh |
| Westhoughton | 928 | +2 kWh |
| Platt Bridge and Abram | 930 | +4 kWh |
PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.
