How Greenhill compares
Small towns rarely get published solar figures, so here are the numbers for Greenhill. It is one of 44 Kent towns we track, and it ranks joint 9th of 44 for solar yield, a town of 7,890 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,111 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 £983 of year one benefit, £247 of it from your own generation and £736 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 Greenhill's own yield.
Canterbury is the planning authority covering Greenhill, 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 Greenhill
On NESO's licence-area map, Greenhill is in South East England, which UK Power Networks operates. That makes UK Power Networks the network operator for any system fitted here.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to UK Power Networks within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
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 Greenhill
A heat pump in Greenhill
A heat pump does most of its work from November to February. Over those four months, 12 panels in Greenhill make about 1,180 kWh, against 3,330 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more 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 Greenhill
A 12-panel roof in Greenhill makes about 870 kWh in July. 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.
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 Greenhill: your questions answered
What does a solar panel system produce in Greenhill?
Each kWp of panels in Greenhill makes 1,111 kWh a year on PVGIS figures, so a typical 12-panel system produces around 7,070 kWh, from about 250 kWh in December up to 870 kWh in July.
How much are solar panels in Greenhill?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Greenhill before a battery. What Greenhill changes is the return, about 7,070 kWh a year from that system, and your design call prices your actual roof.
Would a system in Greenhill need approval from the network operator?
Greenhill is on UK Power Networks' network (South 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 Greenhill?
With typical use and no battery, a 12-panel system in Greenhill exports about 6,129 kWh a year. At 12p per kWh that is roughly £736; 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 Greenhill in winter?
It works, but the year is lopsided. 68% of a Greenhill roof's output lands between April and September; the four months from November to February give about 1,180 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Greenhill compares with its neighbours
How the towns nearest Greenhill compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Greenhill |
|---|---|---|
| Greenhill | 1,111 | this town |
| Herne Bay | 1,111 | level |
| Whitstable | 1,092 | −19 kWh |
| Canterbury | 1,094 | −17 kWh |
| Faversham | 1,082 | −29 kWh |
| Margate | 1,131 | +20 kWh |
| Ramsgate | 1,125 | +14 kWh |
PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.
