How Farnham compares
Small towns rarely get published solar figures, so here are the numbers for Farnham. It is one of 47 Surrey towns we track, and it ranks joint 31st of 47 for solar yield, a town of 21,597 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,020 kWh per kWp a year, 2.79 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £913 of year one benefit, £247 of it from your own generation and £666 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Farnham's own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Any planning application in Farnham sits with Waverley, 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.

SSEN and your Farnham connection
Farnham sits in Scottish and Southern Electricity Networks' Southern England licence area, so SSEN is the network operator (DNO) any solar panels or battery here are registered with.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to SSEN within 28 days of commissioning, with no prior approval.
Larger systems go through G99 instead, applied for before installation. On timing: 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.

Adding a heat pump or an EV charger in Farnham
A heat pump in Farnham
Heating demand peaks when solar is weakest. In Farnham, 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 Farnham
Summer is where a car earns its place. In July, 12 panels in Farnham make about 800 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
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.

Farnham solar questions
How much electricity do solar panels make in Farnham?
About 6,490 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Farnham: 1,020 kWh per kWp, or 2.79 peak sun hours a day on average. July is the strongest month, at about 800 kWh.
What does a typical solar system cost in Farnham?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Farnham, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,490 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Farnham, and what does it need from me?
Scottish and Southern Electricity Networks (SSEN) covers Farnham. 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 happens to the solar I do not use in Farnham?
Around £666 a year at 12p per kWh, for the roughly 5,551 kWh a 12-panel system in Farnham exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Farnham get in December?
December is the low point: about 230 kWh from a 12-panel system in Farnham, on PVGIS data, rising to 800 kWh in July. From November to February the same system makes about 1,110 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Farnham compares with its neighbours
How the towns nearest Farnham compare on the same PVGIS settings, closest first.
