How Petersfield compares
Small towns rarely get published solar figures, so here are the numbers for Petersfield. It is one of 45 Hampshire towns we track, and it ranks 34th of 45 for solar yield, a town of 15,420 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,056 kWh per kWp a year, 2.89 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £941 of year one benefit, £247 of it from your own generation and £694 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Petersfield'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 Petersfield sits with East Hampshire, 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 Petersfield connection
The distribution network operator (DNO) for Petersfield 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.

Adding a heat pump or an EV charger in Petersfield
A heat pump in Petersfield
Heating demand peaks when solar is weakest. In Petersfield, a 12-panel system makes about 230 kWh in December and 260 kWh in January, a fraction of its 820 kWh in June, 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 Petersfield
Petersfield's June output, about 820 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.

Petersfield solar questions
How much energy would 12 solar panels make in Petersfield?
Petersfield averages 2.89 peak sun hours a day, which PVGIS turns into 1,056 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,720 kWh, 68% of it between April and September.
Is solar more expensive in Petersfield?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Petersfield, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,720 kWh a year here, which is what drives payback.
Who is the network operator in Petersfield, 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 could I earn from exporting in Petersfield?
On the 12p export scenario, a 12-panel system in Petersfield sends about 5,779 kWh a year to the grid, worth around £694. The export rates table compares what each supplier pays.
How does solar perform in Petersfield in the winter months?
December is the weakest month in Petersfield: about 230 kWh from 12 panels, against 820 kWh in June. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Petersfield 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 Petersfield |
|---|---|---|
| Petersfield | 1,056 | this town |
| Horndean | 1,111 | +55 kWh |
| Bordon | 1,025 | −31 kWh |
| Waterlooville | 1,125 | +69 kWh |
| Alton | 1,043 | −13 kWh |
| Havant | 1,133 | +77 kWh |
| Emsworth | 1,146 | +90 kWh |
Each row is a PVGIS v5.2 run at that town's centre with the same settings. Treat gaps of a few kWh as noise and gaps over about 30 kWh per kWp as real differences in sunshine.
