Against Great Britain as a whole: Preston makes 889 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Preston is 4% below it.
How Preston compares
Preston is one of 109 Lancashire towns we track, and it ranks 76th of 109 for solar yield. The House of Commons Library settlement data classes it as a large town of 100,502 people. At 889 kWh per kWp a year, a typical 12 panel system here pays for itself in around 7.8 years on the 12p scenario: £813 of year one benefit against £6,360 installed, £247 of that benefit from cutting 26.32p imports with your own generation.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Preston'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.
Preston is its own local planning authority area, and its House of Commons Library settlement class is 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.

Generation is modelled from PVGIS satellite data for Preston's own coordinates (53.77105, -2.69579), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate; the methodology is on our help page.
The network operator for Preston
Electricity North West owns and runs the local electricity network in Preston, 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.

Heat pumps and EV charging in Preston
A heat pump in Preston
Heating demand peaks when solar is weakest. In Preston, a 12-panel system makes about 160 kWh in December and 170 kWh in January, a fraction of its 750 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 Preston
Preston's May output, about 750 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).

Solar panel servicing and repair in Preston
If a system in Preston is underperforming, start with the guides below: repair benchmarks, service scope, and the inverter question.
Solar in Preston: your questions answered
How much energy would 12 solar panels make in Preston?
Preston averages 2.44 peak sun hours a day, which PVGIS turns into 889 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 5,650 kWh, 70% of it between April and September.
Is solar more expensive in Preston?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Preston, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 5,650 kWh a year here, which is what drives payback.
Who is the network operator in Preston, 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 Preston?
On the 12p export scenario, a 12-panel system in Preston sends about 4,717 kWh a year to the grid, worth around £566. The export rates table compares what each supplier pays.
How does solar perform in Preston in the winter months?
December is the weakest month in Preston: about 160 kWh from 12 panels, against 750 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Preston compares with its neighbours
How the towns nearest Preston compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Preston |
|---|---|---|
| Preston | 889 | this town |
| Fulwood | 909 | +20 kWh |
| Penwortham | 909 | +20 kWh |
| Cottam | 931 | +42 kWh |
| Bamber Bridge | 890 | +1 kWh |
| Longton | 931 | +42 kWh |
| Leyland | 896 | +7 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.
