How Swaffham compares
Small towns rarely get published solar figures, so here are the numbers for Swaffham. It is one of 16 Norfolk towns we track, and it ranks 16th of 16 for solar yield, a town of 9,362 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,016 kWh per kWp a year, 2.78 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £910 of year one benefit, £247 of it from your own generation and £663 from export at 12p.
Every figure here assumes a clear, south-facing roof at 35 degrees. Yours will differ, which is what the free design call is for; until then, the calculator below tests panels, batteries and export rates on Swaffham's own yield.
Planning applications here go through Breckland; nationally, the House of Commons Library classes Swaffham as a 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.

UK Power Networks and your Swaffham connection
UK Power Networks owns and runs the local electricity network in Swaffham, as part of its East England licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means UK Power Networks is notified within 28 days of switch-on rather than asked beforehand.
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 UK Power Networks as it does every network operator.

Beyond the panels: heating and car charging in Swaffham
A heat pump in Swaffham
In December, the darkest month here, 12 panels in Swaffham make about 230 kWh. That is when a heat pump runs hardest, so its running cost in Swaffham 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 Swaffham
Swaffham's July 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.
If you rent, or own a flat, and have private off-street parking, the government chargepoint grant covers 75% of the cost, capped at £500 a socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above prices a 7.4kW smart charger from £1,100 installed.

Solar in Swaffham: your questions answered
How much energy would 12 solar panels make in Swaffham?
Swaffham averages 2.78 peak sun hours a day, which PVGIS turns into 1,016 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,460 kWh, 68% of it between April and September.
Is solar more expensive in Swaffham?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Swaffham, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,460 kWh a year here, which is what drives payback.
Who is the network operator in Swaffham, and do I need a G99 application?
The operator is UK Power Networks. 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 UK Power Networks as it does every network operator. Your design call checks which route yours needs.
What could I earn from exporting in Swaffham?
On the 12p export scenario, a 12-panel system in Swaffham sends about 5,525 kWh a year to the grid, worth around £663. The export rates table compares what each supplier pays.
How does solar perform in Swaffham in the winter months?
December is the weakest month in Swaffham: about 230 kWh from 12 panels, against 780 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.

Do solar panels need direct sunlight? Not really, and here is why
No. Solar cells respond to light hitting them, not to a clear line of sight to the sun.
