How Chatteris compares
Small towns rarely get published solar figures, so here are the numbers for Chatteris. It is one of 11 Cambridgeshire towns we track, and it ranks 8th of 11 for solar yield, a town of 10,951 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,033 kWh per kWp a year, 2.83 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £923 of year one benefit, £247 of it from your own generation and £676 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Chatteris' own yield, and prices a 12 panel system at £6,360 installed before any battery. Your free design call reworks every number for your actual roof, its shading and your usage.
Any planning application in Chatteris sits with Fenland, 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.

Generation is modelled from PVGIS satellite data for Chatteris' own coordinates (52.45459, 0.04739), 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.
UK Power Networks and your Chatteris connection
The distribution network operator (DNO) for Chatteris is UK Power Networks, which runs the East England licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means UK Power Networks is notified within 28 days of switch-on rather than asked beforehand.
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 Chatteris
A heat pump in Chatteris
In December, the darkest month here, 12 panels in Chatteris make about 240 kWh. That is when a heat pump runs hardest, so its running cost in Chatteris 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 Chatteris
Chatteris' May 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.
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 panel servicing and repair in Chatteris
If a system in Chatteris is underperforming, start with the guides below: repair benchmarks, service scope, and the inverter question.
Solar in Chatteris: your questions answered
How much energy would 12 solar panels make in Chatteris?
Chatteris averages 2.83 peak sun hours a day, which PVGIS turns into 1,033 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,570 kWh, 67% of it between April and September.
Is solar more expensive in Chatteris?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Chatteris, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,570 kWh a year here, which is what drives payback.
Who is the network operator in Chatteris, 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 Chatteris?
On the 12p export scenario, a 12-panel system in Chatteris sends about 5,633 kWh a year to the grid, worth around £676. The export rates table compares what each supplier pays.
How does solar perform in Chatteris in the winter months?
December is the weakest month in Chatteris: about 240 kWh from 12 panels, against 790 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Chatteris compares with its neighbours
Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.
| Town | kWh per kWp a year | vs Chatteris |
|---|---|---|
| Chatteris | 1,033 | this town |
| March | 1,032 | −1 kWh |
| Ely | 1,029 | −4 kWh |
| St Ives | 1,038 | +5 kWh |
| Whittlesey | 1,035 | +2 kWh |
| Littleport | 1,029 | −4 kWh |
| Huntingdon | 1,039 | +6 kWh |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.
