How Hethersett compares
Small towns rarely get published solar figures, so here are the numbers for Hethersett. It is one of 16 Norfolk towns we track, and it ranks 8th of 16 for solar yield, a town of 7,873 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,034 kWh per kWp a year, 2.83 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £924 of year one benefit, £247 of it from your own generation and £677 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 Hethersett's own yield.
South Norfolk is the planning authority covering Hethersett, which the House of Commons Library classes 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.

Who runs the grid in Hethersett
Hethersett sits in UK Power Networks' East England licence area, so UK Power Networks is the network operator (DNO) any solar panels or battery here are registered with.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to UK Power Networks within 28 days of commissioning, with no prior approval.
A bigger inverter or battery output needs a G99 application in advance. 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 Hethersett
A heat pump in Hethersett
A heat pump does most of its work from November to February. Over those four months, 12 panels in Hethersett make about 1,100 kWh, against 3,110 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Hethersett
From April to September, 68% of a Hethersett 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).

Solar in Hethersett: your questions answered
What does a solar panel system produce in Hethersett?
Each kWp of panels in Hethersett makes 1,034 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,580 kWh, from about 230 kWh in December up to 800 kWh in May.
How much are solar panels in Hethersett?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Hethersett before a battery. What Hethersett changes is the return, about 6,580 kWh a year from that system, and your design call prices your actual roof.
Would a system in Hethersett need approval from the network operator?
Hethersett is on UK Power Networks' network (East England licence area). Systems up to 3.68kW per phase of inverter output follow G98: UK Power 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 UK Power Networks as it does every network operator. Our G98 vs G99 guide explains both routes.
How much can I earn from exporting solar in Hethersett?
With typical use and no battery, a 12-panel system in Hethersett exports about 5,640 kWh a year. At 12p per kWh that is roughly £677; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Is solar worth it in Hethersett in winter?
It works, but the year is lopsided. 68% of a Hethersett roof's output lands between April and September; the four months from November to February give about 1,100 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
