How Wymondham compares
Small towns rarely get published solar figures, so here are the numbers for Wymondham. It is one of 16 Norfolk towns we track, and it ranks joint 5th of 16 for solar yield, a town of 18,290 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,036 kWh per kWp a year, 2.84 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £925 of year one benefit, £247 of it from your own generation and £678 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Wymondham'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.
Wymondham sits within South Norfolk, its local planning authority, and the House of Commons Library classes it 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.

Connecting solar to the Wymondham network
Wymondham is served by UK Power Networks: the town's centre falls inside its East England licence area on NESO's boundary map.
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: UK Power 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 UK Power Networks as it does every network operator.

Adding a heat pump or an EV charger in Wymondham
A heat pump in Wymondham
Solar and a heat pump pull in opposite directions through the year: Wymondham's roofs make 1,100 kWh from November to February on a 12-panel system, and 3,110 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Wymondham
From April to September, 68% of a Wymondham roof's yearly output arrives, peaking at about 800 kWh in May on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
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).

Common questions about solar in Wymondham
What could a roof in Wymondham generate?
PVGIS puts a roof in Wymondham at 1,036 kWh per kWp a year, 2.84 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,590 kWh a year, most of it between April and September.
How much are solar panels in Wymondham?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Wymondham before a battery. What Wymondham changes is the return, about 6,590 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Wymondham?
Usually not in advance. UK Power Networks, the network operator for Wymondham, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval 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. "See our DNO explainer.
How much can I earn from exporting solar in Wymondham?
With typical use and no battery, a 12-panel system in Wymondham exports about 5,652 kWh a year. At 12p per kWh that is roughly £678; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in Wymondham?
Yes, at a lower level. PVGIS gives Wymondham 35.8 kWh per kWp in December and 38.6 in January, so a 12-panel system makes about 230 kWh and 250 kWh in those months, against 800 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Wymondham compares with its neighbours
Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.
| Town | kWh per kWp a year | vs Wymondham |
|---|---|---|
| Wymondham | 1,036 | this town |
| Hethersett | 1,034 | −2 kWh |
| Attleborough | 1,036 | level |
| Taverham and Drayton | 1,026 | −10 kWh |
| Norwich | 1,033 | −3 kWh |
| Dereham | 1,028 | −8 kWh |
| Watton | 1,017 | −19 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.
