How Penwortham compares
Small towns rarely get published solar figures, so here are the numbers for Penwortham. It is one of 109 Lancashire towns we track, and it ranks joint 55th of 109 for solar yield, a town of 20,842 people in the House of Commons Library settlement data. PVGIS gives its roofs 909 kWh per kWp a year, 2.49 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £828 of year one benefit, £247 of it from your own generation and £581 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Penwortham'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 Penwortham 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 Penwortham
Penwortham sits in Electricity North West's North West England licence area, so Electricity North West is the network operator (DNO) any solar panels or battery here are registered with.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, Electricity North West only has to be told within 28 days after the system is commissioned.
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 Penwortham
A heat pump in Penwortham
In December, the darkest month here, 12 panels in Penwortham make about 170 kWh. That is when a heat pump runs hardest, so its running cost in Penwortham comes down to the tariff and the flow temperature rather 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 Penwortham
Summer is where a car earns its place. In May, 12 panels in Penwortham 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.
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).

Solar in Penwortham: your questions answered
How much electricity do solar panels make in Penwortham?
About 5,780 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Penwortham: 909 kWh per kWp, or 2.49 peak sun hours a day on average. May is the strongest month, at about 760 kWh.
What does a typical solar system cost in Penwortham?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Penwortham, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 5,780 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Penwortham, and what does it need from me?
Electricity North West covers Penwortham. 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 Penwortham?
Around £581 a year at 12p per kWh, for the roughly 4,845 kWh a 12-panel system in Penwortham 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 Penwortham get in December?
December is the low point: about 170 kWh from a 12-panel system in Penwortham, on PVGIS data, rising to 760 kWh in May. From November to February the same system makes about 890 kWh in total, which is why a battery charged off-peak does more of the work in winter.
