Against Great Britain as a whole: Tadley makes 1,032 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Tadley is 12% above it.
How Tadley compares
Small towns rarely get published solar figures, so here are the numbers for Tadley. It is one of 45 Hampshire towns we track, and it ranks 39th of 45 for solar yield, a town of 14,985 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,032 kWh per kWp a year, 2.83 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £922 of year one benefit, £247 of it from your own generation and £675 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Tadley'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 Tadley sits with Basingstoke and Deane, 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 Tadley
Tadley 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.
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.
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.

Heat pumps and EV charging in Tadley
A heat pump in Tadley
In December, the darkest month here, 12 panels in Tadley make about 230 kWh. That is when a heat pump runs hardest, so its running cost in Tadley 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 Tadley
Summer is where a car earns its place. In July, 12 panels in Tadley 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.
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.

Tadley solar questions
How much energy would 12 solar panels make in Tadley?
Tadley averages 2.83 peak sun hours a day, which PVGIS turns into 1,032 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,560 kWh, 68% of it between April and September.
What does a typical solar system cost in Tadley?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Tadley, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,560 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Tadley, 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 happens to the solar I do not use in Tadley?
Around £675 a year at 12p per kWh, for the roughly 5,627 kWh a 12-panel system in Tadley exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How does solar perform in Tadley in the winter months?
December is the weakest month in Tadley: 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.
How Tadley compares with its neighbours
Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.
| Town | kWh per kWp a year | vs Tadley |
|---|---|---|
| Tadley | 1,032 | this town |
| Thatcham | 1,025 | −7 kWh |
| Basingstoke | 1,031 | −1 kWh |
| Newbury | 1,034 | +2 kWh |
| Reading | 1,028 | −4 kWh |
| Hook | 1,036 | +4 kWh |
| Caversham | 1,025 | −7 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.
