Oxford's solar year
From 36.5 kWh per kWp in December to 125.3 in July: a roof in Oxford makes 3.4 times as much in its best month as in its darkest, and 1,022 kWh per kWp across the year.

How Oxford compares
Oxford is one of 10 Oxfordshire towns we track, and it ranks 4th of 10 for solar yield. The House of Commons Library settlement data classes it as a large town of 173,292 people. At 1,022 kWh per kWp a year, a typical 12 panel system here pays for itself in around 7.0 years on the 12p scenario: £914 of year one benefit against £6,360 installed, £247 of that benefit from cutting 26.32p imports with your own generation.
These are starting numbers, not a quote. The calculator below opens on Oxford'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.
Planning applications in Oxford go to its own council, and the House of Commons Library classes it as a large 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 Oxford's own coordinates (51.74969, -1.23601), 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 Oxford
Oxford sits in Scottish and Southern Electricity Networks' Southern England licence area, so SSEN 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 SSEN within 28 days of commissioning, with no prior approval.
A bigger inverter or battery output needs a G99 application in advance. SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW.

Adding a heat pump or an EV charger in Oxford
A heat pump in Oxford
A heat pump does most of its work from November to February. Over those four months, 12 panels in Oxford make about 1,140 kWh, against 3,050 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 Oxford
From April to September, 67% of a Oxford roof's yearly output arrives, peaking at about 800 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.
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).

Common questions about solar in Oxford
What does a solar panel system produce in Oxford?
Each kWp of panels in Oxford makes 1,022 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,500 kWh, from about 230 kWh in December up to 800 kWh in July.
How much are solar panels in Oxford?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Oxford before a battery. What Oxford changes is the return, about 6,500 kWh a year from that system, and your design call prices your actual roof.
Would a system in Oxford need approval from the network operator?
Oxford is on Scottish and Southern Electricity Networks' network (Southern England licence area). Systems up to 3.68kW per phase of inverter output follow G98: SSEN is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW. Our G98 vs G99 guide explains both routes.
How much can I earn from exporting solar in Oxford?
With typical use and no battery, a 12-panel system in Oxford exports about 5,563 kWh a year. At 12p per kWh that is roughly £668; 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 Oxford in winter?
It works, but the year is lopsided. 67% of a Oxford roof's output lands between April and September; the four months from November to February give about 1,140 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Oxford compares with its neighbours
How the towns nearest Oxford compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Oxford |
|---|---|---|
| Oxford | 1,022 | this town |
| Abingdon-on-Thames | 1,027 | +5 kWh |
| Kidlington | 1,014 | −8 kWh |
| Didcot | 1,040 | +18 kWh |
| Bicester | 1,020 | −2 kWh |
| Thame | 1,009 | −13 kWh |
| Wallingford | 1,017 | −5 kWh |
Each row is a PVGIS v5.2 run at that town's centre with the same settings. Treat gaps of a few kWh as noise and gaps over about 30 kWh per kWp as real differences in sunshine.
