How Southport compares
Southport is one of 109 Lancashire towns we track, and it ranks 10th of 109 for solar yield. The House of Commons Library settlement data classes it as a large town of 96,394 people. At 1,001 kWh per kWp a year, a typical 12 panel system here pays for itself in around 7.1 years on the 12p scenario: £898 of year one benefit against £6,360 installed, £247 of that benefit from cutting 26.32p imports with your own generation.
These are starting numbers, not a quote. The calculator below opens on Southport's own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Southport sits within Sefton, its local planning authority, and the House of Commons Library classes it as a large 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.

Connecting solar to the Southport network
On NESO's licence-area map, Southport is in North Wales, Merseyside and Cheshire, which SP Energy Networks operates. That makes SP Energy Networks 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 SP Energy Networks within 28 days of commissioning, with no prior approval.
A bigger inverter or battery output needs a G99 application in advance. 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 SP Energy Networks as it does every network operator.

Adding a heat pump or an EV charger in Southport
A heat pump in Southport
Solar and a heat pump pull in opposite directions through the year: Southport's roofs make 980 kWh from November to February on a 12-panel system, and 3,100 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
Grant support in England comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Southport
A 12-panel roof in Southport makes about 830 kWh in May. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Common questions about solar in Southport
What could a roof in Southport generate?
PVGIS puts a roof in Southport at 1,001 kWh per kWp a year, 2.74 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,370 kWh a year, most of it between April and September.
What would 12 solar panels cost in Southport?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Southport differs is output: about 6,370 kWh a year from that system.
Do I need permission from the DNO for solar in Southport?
Usually not in advance. SP Energy Networks, the network operator for Southport, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval first. 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 SP Energy Networks as it does every network operator. "See our DNO explainer.
How much would export pay on a system in Southport?
It is exported. With typical use and no battery, about 5,430 kWh of the 6,370 kWh a 12-panel system makes in Southport goes to the grid, around £652 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Do solar panels work in winter in Southport?
Yes, at a lower level. PVGIS gives Southport 29.1 kWh per kWp in December and 31.4 in January, so a 12-panel system makes about 190 kWh and 200 kWh in those months, against 830 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Southport compares with its neighbours
How the towns nearest Southport compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Southport |
|---|---|---|
| Southport | 1,001 | this town |
| Formby | 1,017 | +16 kWh |
| Burscough | 958 | −43 kWh |
| Ormskirk | 958 | −43 kWh |
| Tarleton and Hesketh Bank | 963 | −38 kWh |
| Lytham St Anne's | 1,015 | +14 kWh |
| Maghull | 973 | −28 kWh |
Each row is a PVGIS v5.2 run at that town's centre with the same settings. Treat gaps of a few kWh as noise and gaps over about 30 kWh per kWp as real differences in sunshine.
