How Ashford Common compares
Small towns rarely get published solar figures, so here are the numbers for Ashford Common. It is one of 23 Middlesex towns we track, and it ranks joint 15th of 23 for solar yield, a town of 8,491 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,024 kWh per kWp a year, 2.81 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £916 of year one benefit, £247 of it from your own generation and £669 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Ashford Common's 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 Ashford Common sits with Spelthorne, 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 Ashford Common's own coordinates (51.42157, -0.43935), 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.
SSEN and your Ashford Common connection
The distribution network operator (DNO) for Ashford Common is Scottish and Southern Electricity Networks (SSEN), which runs the Southern England licence area.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, SSEN only has to be told within 28 days after the system is commissioned.
Above that, G99 means applying before the work is booked. 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.

Heat pumps and EV charging in Ashford Common
A heat pump in Ashford Common
Heating demand peaks when solar is weakest. In Ashford Common, a 12-panel system makes about 230 kWh in December and 250 kWh in January, a fraction of its 800 kWh in July, which is why a heat pump here is costed on its tariff first.
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 Ashford Common
Ashford Common's July output, about 800 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.

Solar in Ashford Common: your questions answered
How much energy would 12 solar panels make in Ashford Common?

Is solar more expensive in Ashford Common?

Who is the network operator in Ashford Common, and do I need a G99 application?
The operator is Scottish and Southern Electricity Networks (SSEN). 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. 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. Your design call checks which route yours needs.
What could I earn from exporting in Ashford Common?
On the 12p export scenario, a 12-panel system in Ashford Common sends about 5,576 kWh a year to the grid, worth around £669. The export rates table compares what each supplier pays.
How does solar perform in Ashford Common in the winter months?
December is the weakest month in Ashford Common: about 230 kWh from 12 panels, against 800 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
