How Sudbury compares
Among the places we publish figures for, Sudbury is one of 16 Suffolk towns we track, and it ranks 11th of 16 for solar yield. It is a medium town in the House of Commons Library classification, with 25,051 residents, and its roofs see 2.89 peak sun hours a day across the year. That drives the standard 12 panel model to 6,703 kWh of generation, of which around 5,767 kWh is exported at 12p for £692 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Sudbury'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.
Babergh is the planning authority covering Sudbury, which the House of Commons Library classes as a medium 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 Sudbury's own coordinates (52.03824, 0.74001), 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.
Who runs the grid in Sudbury
UK Power Networks owns and runs the local electricity network in Sudbury, 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.
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.

Heat pumps and EV charging in Sudbury
A heat pump in Sudbury
A heat pump does most of its work from November to February. Over those four months, 12 panels in Sudbury make about 1,150 kWh, against 3,130 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
In England, the Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump and £2,500 towards an air-to-air one, with £1,500 more until March 2027 for homes heated by oil or LPG with no mains gas (gov.uk, checked 28 September 2026).
Charging an EV in Sudbury
A 12-panel roof in Sudbury makes about 800 kWh in June. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Solar in Sudbury: your questions answered
What does a solar panel system produce in Sudbury?
Each kWp of panels in Sudbury makes 1,054 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,700 kWh, from about 240 kWh in December up to 800 kWh in June.
What would 12 solar panels cost in Sudbury?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Sudbury differs is output: about 6,700 kWh a year from that system.
Would a system in Sudbury need approval from the network operator?
Sudbury 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 would export pay on a system in Sudbury?
It is exported. With typical use and no battery, about 5,767 kWh of the 6,700 kWh a 12-panel system makes in Sudbury goes to the grid, around £692 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Is solar worth it in Sudbury in winter?
It works, but the year is lopsided. 68% of a Sudbury roof's output lands between April and September; the four months from November to February give about 1,150 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Sudbury compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Sudbury.
| Town | kWh per kWp a year | vs Sudbury |
|---|---|---|
| Sudbury | 1,054 | this town |
| Halstead | 1,062 | +8 kWh |
| Hadleigh | 1,072 | +18 kWh |
| Colchester | 1,082 | +28 kWh |
| Haverhill | 1,043 | −11 kWh |
| Braintree | 1,065 | +11 kWh |
| Berechurch | 1,091 | +37 kWh |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.
