How Chinnor compares
Small towns rarely get published solar figures, so here are the numbers for Chinnor. It is one of 10 Oxfordshire towns we track, and it ranks 10th of 10 for solar yield, a town of 7,666 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,005 kWh per kWp a year, 2.75 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £902 of year one benefit, £247 of it from your own generation and £655 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Chinnor'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.
Any planning application in Chinnor sits with South Oxfordshire, and its official House of Commons Library settlement class is 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.

UK Power Networks and your Chinnor connection
UK Power Networks owns and runs the local electricity network in Chinnor, as part of its East England licence area.
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.
Above that, G99 means applying before the work is booked. 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 Chinnor
A heat pump in Chinnor
In December, the darkest month here, 12 panels in Chinnor make about 220 kWh. That is when a heat pump runs hardest, so its running cost in Chinnor comes down to the tariff and the flow temperature rather 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 Chinnor
Chinnor's July output, about 790 kWh from 12 panels, is several times the 70 kWh or so a typical home uses in daylight that month on our calculator's settings. Daytime charging turns that surplus into miles.
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 Chinnor
How much energy would 12 solar panels make in Chinnor?
Chinnor averages 2.75 peak sun hours a day, which PVGIS turns into 1,005 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,390 kWh, 68% of it between April and September.
Is solar more expensive in Chinnor?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Chinnor, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,390 kWh a year here, which is what drives payback.
Who is the network operator in Chinnor, and do I need a G99 application?
The operator is UK Power Networks. Most home systems use the G98 route, a notification within 28 days of switch-on for up to 3.68kW per phase, so nothing waits on the network. Above that, G99 applies and has to be granted 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. Your design call checks which route yours needs.
What could I earn from exporting in Chinnor?
On the 12p export scenario, a 12-panel system in Chinnor sends about 5,455 kWh a year to the grid, worth around £655. The export rates table compares what each supplier pays.
How does solar perform in Chinnor in the winter months?
December is the weakest month in Chinnor: about 220 kWh from 12 panels, against 790 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Chinnor compares with its neighbours

| Princes Risborough | 997 | −8 kWh |
| Thame | 1,009 | +4 kWh |
| Prestwood and Great Missenden | 1,002 | −3 kWh |
| High Wycombe | 1,012 | +7 kWh |
| Wendover | 1,000 | −5 kWh |
| Aylesbury | 995 | −10 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.
