Against Great Britain as a whole: Cambridgeshire makes 1,036 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Cambridgeshire is 12% above it.
How Cambridgeshire compares
Cambridgeshire ranks 10th of the 85 counties we track for solar yield, which puts export income near the top of the country. On the 12p scenario a 12 panel system here sends about 5,652 kWh to the grid a year on top of the £247 it saves you directly, so oversizing the array is usually the right call.
Treat these as calibration rather than a quote. The calculator below opens on Cambridgeshire's own PVGIS yield and prices a 12 panel system at £6,360 installed before any battery; your free design call reworks every number for your roof.
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 from PVGIS v5.2 (European Commission JRC, SARAH3), retrieved August 2026 for a representative point in Cambridgeshire (52.3393, 0.1322), assuming 1 kWp, 14% system loss, 35 degree pitch, due south. Import valued at 26.32p/kWh (Ofgem price cap average, Oct to Dec 2026); off-peak charging at 8.5p/kWh where used (a supplier's published off-peak rate, checked September 2026); export at the scenario you pick, from the dated tariff table. Prices are installed pricing, August 2026, standard installations; 530W LONGi panels at £1,000 per kWp. Estimates for illustration, not a quote: your free design call prices your actual roof.
UK Power Networks and your Cambridgeshire connection
UK Power Networks is the distribution network operator (DNO) for Cambridgeshire, running 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.

Heat pumps and EV charging in Cambridgeshire
A heat pump in Cambridgeshire
Heating demand peaks when solar is weakest. In Cambridgeshire, a 12-panel system makes about 240 kWh in December and 250 kWh in January, a fraction of its 790 kWh in July, which is why a heat pump here is costed on its tariff first.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Cambridgeshire
Cambridgeshire'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.
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).

Cambridgeshire solar questions
How much electricity do solar panels make in Cambridgeshire?
About 6,590 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Cambridgeshire: 1,036 kWh per kWp, or 2.84 peak sun hours a day on average. July is the strongest month, at about 790 kWh.
Is solar more expensive in Cambridgeshire?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Cambridgeshire, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,590 kWh a year here, which is what drives payback.
Which DNO covers Cambridgeshire, and what does it need from me?
UK Power Networks covers Cambridgeshire. A home system of up to 3.68kW per phase is notified to UK Power Networks within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. 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.
What could I earn from exporting in Cambridgeshire?
On the 12p export scenario, a 12-panel system in Cambridgeshire sends about 5,652 kWh a year to the grid, worth around £678. The export rates table compares what each supplier pays.
How much solar does Cambridgeshire get in December?
December is the low point: about 240 kWh from a 12-panel system in Cambridgeshire, on PVGIS data, rising to 790 kWh in July. From November to February the same system makes about 1,160 kWh in total, which is why a battery charged off-peak does more of the work in winter.
