How Prescot compares
Among the places we publish figures for, Prescot is one of 109 Lancashire towns we track, and it ranks 25th of 109 for solar yield. It is a medium town in the House of Commons Library classification, with 41,278 residents, and its roofs see 2.59 peak sun hours a day across the year. That drives the standard 12 panel model to 6,004 kWh of generation, of which around 5,067 kWh is exported at 12p for £608 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
These are starting numbers, not a quote. The calculator below opens on Prescot'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.
Knowsley is the planning authority covering Prescot, which the House of Commons Library classes as a 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.

Who runs the grid in Prescot
SP Energy Networks owns and runs the local electricity network in Prescot, as part of its North Wales, Merseyside and Cheshire 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: SP Energy Networks is notified within 28 days of commissioning and nothing has to be approved first.
Anything bigger is a G99 case and is applied for 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.

Adding a heat pump or an EV charger in Prescot
A heat pump in Prescot
A heat pump does most of its work from November to February. Over those four months, 12 panels in Prescot make about 940 kWh, against 2,920 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Prescot
A 12-panel roof in Prescot makes about 780 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).

Prescot solar questions
What does a solar panel system produce in Prescot?
Each kWp of panels in Prescot makes 944 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,000 kWh, from about 180 kWh in December up to 780 kWh in May.
What would 12 solar panels cost in Prescot?
£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 Prescot differs is output: about 6,000 kWh a year from that system.
Would a system in Prescot need approval from the network operator?
Prescot is on SP Energy Networks' network (North Wales, Merseyside and Cheshire licence area). Systems up to 3.68kW per phase of inverter output follow G98: SP Energy Networks is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. 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. Our G98 vs G99 guide explains both routes.
How much would export pay on a system in Prescot?
It is exported. With typical use and no battery, about 5,067 kWh of the 6,000 kWh a 12-panel system makes in Prescot goes to the grid, around £608 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Is solar worth it in Prescot in winter?
It works, but the year is lopsided. 69% of a Prescot roof's output lands between April and September; the four months from November to February give about 940 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.

| Kirkby | 958 | +14 kWh |
| Haydock | 933 | −11 kWh |
