How Addlestone compares
Small towns rarely get published solar figures, so here are the numbers for Addlestone. It is one of 47 Surrey towns we track, and it ranks joint 24th of 47 for solar yield, a town of 14,349 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.
These are starting numbers, not a quote. The calculator below opens on Addlestone'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 Addlestone sits with Runnymede, 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 Addlestone's own coordinates (51.37216, -0.48881), 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 Addlestone connection
UK Power Networks owns and runs the local electricity network in Addlestone, as part of its South 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.

Adding a heat pump or an EV charger in Addlestone
A heat pump in Addlestone
In December, the darkest month here, 12 panels in Addlestone make about 220 kWh. That is when a heat pump runs hardest, so its running cost in Addlestone comes down to the tariff and the flow temperature rather than the roof.
Grant support in England comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Addlestone
Addlestone's July output, about 810 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.

Common questions about solar in Addlestone
How much electricity do solar panels make in Addlestone?
About 6,510 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Addlestone: 1,024 kWh per kWp, or 2.81 peak sun hours a day on average. July is the strongest month, at about 810 kWh.
Is solar more expensive in Addlestone?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Addlestone, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,510 kWh a year here, which is what drives payback.
Which DNO covers Addlestone, and what does it need from me?
UK Power Networks covers Addlestone. A home system of up to 3.68kW per phase is notified to UK Power Networks within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. 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.
What could I earn from exporting in Addlestone?
On the 12p export scenario, a 12-panel system in Addlestone sends about 5,576 kWh a year to the grid, worth around £669. The export rates table compares what each supplier pays.
How much solar does Addlestone get in December?
December is the low point: about 220 kWh from a 12-panel system in Addlestone, on PVGIS data, rising to 810 kWh in July. From November to February the same system makes about 1,100 kWh in total, which is why a battery charged off-peak does more of the work in winter.

DNO application timescales, network by network: from a G98 notification to a G99 approval
Fit and notify within 28 days, or wait ten working days to 45 for a yes. System size decides which.
Read the guide →Does a standalone battery actually pay back?
No panels means one job: buy cheap, use later. The tariff decides whether it pays.
Read the guide →Charging an EV from your own solar
Every surplus kWh is 3.6 to 5 miles. Whether that beats a 7p overnight rate is arithmetic.
Read the guide →How much does a heat pump cost? The 2026 numbers, before and after the grant
UK median installed cost around £12,908, before the up to £7,500 grant comes off.

Identical kit, five times the export income. The tariff decision worked through with August 2026 rates.
