How Cambourne compares
Small towns rarely get published solar figures, so here are the numbers for Cambourne. It is one of 11 Cambridgeshire towns we track, and it ranks 6th of 11 for solar yield, a town of 12,143 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,036 kWh per kWp a year, 2.84 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £925 of year one benefit, £247 of it from your own generation and £678 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 Cambourne's own yield.
South Cambridgeshire is the planning authority covering Cambourne, 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.

Generation is modelled from PVGIS satellite data for Cambourne's own coordinates (52.21779, -0.06822), 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 Cambourne
On NESO's licence-area map, Cambourne is in 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 Cambourne
A heat pump in Cambourne
A heat pump does most of its work from November to February. Over those four months, 12 panels in Cambourne make about 1,150 kWh, against 3,070 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 Cambourne
A 12-panel roof in Cambourne makes about 790 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.
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 Cambourne
What does a solar panel system produce in Cambourne?
Each kWp of panels in Cambourne makes 1,036 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,590 kWh, from about 240 kWh in December up to 790 kWh in July.
What would 12 solar panels cost in Cambourne?
£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 Cambourne differs is output: about 6,590 kWh a year from that system.
Would a system in Cambourne need approval from the network operator?
Cambourne 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 Cambourne?
It is exported. With typical use and no battery, about 5,652 kWh of the 6,590 kWh a 12-panel system makes in Cambourne goes to the grid, around £678 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 Cambourne in winter?
It works, but the year is lopsided. 67% of a Cambourne 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 Cambourne compares with its neighbours
How the towns nearest Cambourne compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Cambourne |
|---|---|---|
| Cambourne | 1,036 | this town |
| Histon and Impington | 1,037 | +1 kWh |
| Godmanchester | 1,039 | +3 kWh |
| St Ives | 1,038 | +2 kWh |
| St Neots | 1,026 | −10 kWh |
| Cambridge | 1,037 | +1 kWh |
| Huntingdon | 1,039 | +3 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.
