How Whiteley compares
Small towns rarely get published solar figures, so here are the numbers for Whiteley. It is one of 45 Hampshire towns we track, and it ranks joint 25th of 45 for solar yield, a town of 9,919 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,090 kWh per kWp a year, 2.99 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £966 of year one benefit, £247 of it from your own generation and £719 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Whiteley'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.
Planning applications here go through Winchester; nationally, the House of Commons Library classes Whiteley 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.

The network operator for Whiteley
The distribution network operator (DNO) for Whiteley is Scottish and Southern Electricity Networks (SSEN), which runs the Southern 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 SSEN is notified within 28 days of switch-on rather than asked beforehand.
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.

Heat pumps and EV charging in Whiteley
A heat pump in Whiteley
In December, the darkest month here, 12 panels in Whiteley make about 240 kWh. That is when a heat pump runs hardest, so its running cost in Whiteley 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 Whiteley
Whiteley's July output, about 860 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.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Solar in Whiteley: your questions answered
How much electricity do solar panels make in Whiteley?
About 6,930 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Whiteley: 1,090 kWh per kWp, or 2.99 peak sun hours a day on average. July is the strongest month, at about 860 kWh.
Is solar more expensive in Whiteley?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Whiteley, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,930 kWh a year here, which is what drives payback.
Which DNO covers Whiteley, and what does it need from me?
Scottish and Southern Electricity Networks (SSEN) covers Whiteley. 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 Whiteley?
On the 12p export scenario, a 12-panel system in Whiteley sends about 5,996 kWh a year to the grid, worth around £719. The export rates table compares what each supplier pays.
How much solar does Whiteley get in December?
December is the low point: about 240 kWh from a 12-panel system in Whiteley, on PVGIS data, rising to 860 kWh in July. From November to February the same system makes about 1,160 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Whiteley 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 Whiteley |
|---|---|---|
| Whiteley | 1,090 | this town |
| Locks Heath | 1,090 | level |
| Bursledon | 1,092 | +2 kWh |
| Hedge End | 1,084 | −6 kWh |
| Fareham | 1,117 | +27 kWh |
| West End | 1,085 | −5 kWh |
| Lee-on-the-Solent | 1,104 | +14 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.
