How Longton compares
Small towns rarely get published solar figures, so here are the numbers for Longton. It is one of 109 Lancashire towns we track, and it ranks joint 35th of 109 for solar yield, a town of 11,213 people in the House of Commons Library settlement data. PVGIS gives its roofs 931 kWh per kWp a year, 2.55 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £845 of year one benefit, £247 of it from your own generation and £598 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Longton'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.
Any planning application in Longton sits with South Ribble, and its official House of Commons Library settlement class is small 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 Longton
Electricity North West owns and runs the local electricity network in Longton, as part of its North West England licence area.
What decides the paperwork is the inverter and battery output, not the number of panels. Up to 3.68kW per phase, a system follows G98: Electricity North West is notified within 28 days of commissioning and nothing has to be approved first.
Above that, G99 means applying before the work is booked. 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.

Adding a heat pump or an EV charger in Longton
A heat pump in Longton
Heating demand peaks when solar is weakest. In Longton, a 12-panel system makes about 170 kWh in December and 180 kWh in January, a fraction of its 780 kWh in May, which is why a heat pump here is costed on its tariff first.
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 Longton
Longton's May output, about 780 kWh from 12 panels, is several times the 70 kWh or so a typical home uses in daylight that month on our calculator's settings. Daytime charging turns that surplus into miles.
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).

Longton solar questions
How much energy would 12 solar panels make in Longton?
Longton averages 2.55 peak sun hours a day, which PVGIS turns into 931 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 5,920 kWh, 70% of it between April and September.
Is solar more expensive in Longton?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Longton, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 5,920 kWh a year here, which is what drives payback.
Who is the network operator in Longton, and do I need a G99 application?
The operator is Electricity North West. Most home systems use the G98 route, a notification within 28 days of switch-on for up to 3.68kW per phase, so nothing waits on the network. Above that, G99 applies and has to be granted 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 Electricity North West as it does every network operator. Your design call checks which route yours needs.
What could I earn from exporting in Longton?
On the 12p export scenario, a 12-panel system in Longton sends about 4,984 kWh a year to the grid, worth around £598. The export rates table compares what each supplier pays.
How does solar perform in Longton in the winter months?
December is the weakest month in Longton: about 170 kWh from 12 panels, against 780 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
