How Godalming compares
Small towns rarely get published solar figures, so here are the numbers for Godalming. It is one of 47 Surrey towns we track, and it ranks joint 17th of 47 for solar yield, a town of 11,432 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,025 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 £917 of year one benefit, £247 of it from your own generation and £670 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Godalming'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.
Waverley is the planning authority covering Godalming, which the House of Commons Library classes as a 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 Godalming's own coordinates (51.18244, -0.6093), 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.
Who runs the grid in Godalming
Godalming is served by Scottish and Southern Electricity Networks (SSEN): the town's centre falls inside its Southern England licence area on NESO's boundary map.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to SSEN within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
Anything bigger is a G99 case and is applied for 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.

Adding a heat pump or an EV charger in Godalming
A heat pump in Godalming
A heat pump does most of its work from November to February. Over those four months, 12 panels in Godalming make about 1,080 kWh, against 3,110 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more 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 Godalming
A 12-panel roof in Godalming makes about 810 kWh in July. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
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.

Common questions about solar in Godalming
What does a solar panel system produce in Godalming?
Each kWp of panels in Godalming makes 1,025 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,520 kWh, from about 220 kWh in December up to 810 kWh in July.
What would 12 solar panels cost in Godalming?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Godalming differs is output: about 6,520 kWh a year from that system.
Would a system in Godalming need approval from the network operator?
Godalming is on Scottish and Southern Electricity Networks' network (Southern England licence area). Systems up to 3.68kW per phase of inverter output follow G98: SSEN is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. 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. Our G98 vs G99 guide explains both routes.
How much would export pay on a system in Godalming?
It is exported. With typical use and no battery, about 5,582 kWh of the 6,520 kWh a 12-panel system makes in Godalming goes to the grid, around £670 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Is solar worth it in Godalming in winter?
It works, but the year is lopsided. 68% of a Godalming roof's output lands between April and September; the four months from November to February give about 1,080 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Godalming compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Godalming.

| Farncombe | 1,034 | +9 kWh |
| Guildford | 1,028 | +3 kWh |
| Cranleigh | 1,050 | +25 kWh |
| Ash and Ash Vale | 1,024 | −1 kWh |
| Aldershot | 1,021 | −4 kWh |
| Farnham | 1,020 | −5 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.
