How Staines-upon-Thames compares
Small towns rarely get published solar figures, so here are the numbers for Staines-upon-Thames. It is one of 23 Middlesex towns we track, and it ranks joint 15th of 23 for solar yield, a town of 22,249 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.
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 Staines-upon-Thames' own yield.
Any planning application in Staines-upon-Thames 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.

The network operator for Staines-upon-Thames
Scottish and Southern Electricity Networks (SSEN) owns and runs the local electricity network in Staines-upon-Thames, as part of its Southern 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: SSEN is notified within 28 days of commissioning and nothing has to be approved first.
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.

Beyond the panels: heating and car charging in Staines-upon-Thames
A heat pump in Staines-upon-Thames
Heating demand peaks when solar is weakest. In Staines-upon-Thames, 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 Staines-upon-Thames
Staines-upon-Thames' 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.

Which DNO covers Staines-upon-Thames, and what does it need from me?
Scottish and Southern Electricity Networks (SSEN) covers Staines-upon-Thames. A home system of up to 3.68kW per phase is notified to SSEN within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. 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.
What could I earn from exporting in Staines-upon-Thames?

How much solar does Staines-upon-Thames get in December?
December is the low point: about 230 kWh from a 12-panel system in Staines-upon-Thames, on PVGIS data, rising to 800 kWh in July. From November to February the same system makes about 1,120 kWh in total, which is why a battery charged off-peak does more of the work in winter.
