Against Great Britain as a whole: Heathfield makes 1,110 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Heathfield is 20% above it.
How Heathfield compares
Small towns rarely get published solar figures, so here are the numbers for Heathfield. It is one of 33 Sussex towns we track, and it ranks 26th of 33 for solar yield, a town of 7,872 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,110 kWh per kWp a year, 3.04 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £982 of year one benefit, £247 of it from your own generation and £735 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 Heathfield's own yield.
Heathfield sits within Wealden, 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.

Generation is modelled from PVGIS satellite data for Heathfield's own coordinates (50.96737, 0.25184), 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.
Connecting solar to the Heathfield network
The distribution network operator (DNO) for Heathfield is UK Power Networks, which runs the South 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.

Beyond the panels: heating and car charging in Heathfield
A heat pump in Heathfield
Solar and a heat pump pull in opposite directions through the year: Heathfield's roofs make 1,190 kWh from November to February on a 12-panel system, and 3,360 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Heathfield
From April to September, 68% of a Heathfield roof's yearly output arrives, peaking at about 880 kWh in July 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.
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.

Common questions about solar in Heathfield
What could a roof in Heathfield generate?
PVGIS puts a roof in Heathfield at 1,110 kWh per kWp a year, 3.04 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 7,060 kWh a year, most of it between April and September.
What would 12 solar panels cost in Heathfield?
£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 Heathfield differs is output: about 7,060 kWh a year from that system.
Do I need permission from the DNO for solar in Heathfield?
Usually not in advance. UK Power Networks, the network operator for Heathfield, 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 would export pay on a system in Heathfield?
It is exported. With typical use and no battery, about 6,123 kWh of the 7,060 kWh a 12-panel system makes in Heathfield goes to the grid, around £735 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Do solar panels work in winter in Heathfield?
Yes, at a lower level. PVGIS gives Heathfield 39.9 kWh per kWp in December and 42 in January, so a 12-panel system makes about 250 kWh and 270 kWh in those months, against 880 kWh in July. Winter output mostly covers daytime use rather than exporting.
How Heathfield compares with its neighbours

| Royal Tunbridge Wells | 1,054 | −56 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.
