How Emsworth compares
Small towns rarely get published solar figures, so here are the numbers for Emsworth. It is one of 45 Hampshire towns we track, and it ranks 3rd of 45 for solar yield, a town of 12,111 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,146 kWh per kWp a year, 3.14 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £1,009 of year one benefit, £247 of it from your own generation and £762 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Emsworth'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.
Planning applications here go through Havant; nationally, the House of Commons Library classes Emsworth 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.

SSEN and your Emsworth connection
The distribution network operator (DNO) for Emsworth 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 Emsworth
A heat pump in Emsworth
Heating demand peaks when solar is weakest. In Emsworth, a 12-panel system makes about 260 kWh in December and 270 kWh in January, a fraction of its 910 kWh in July, which is why a heat pump here is costed on its tariff first.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Emsworth
Emsworth's July output, about 910 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.
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 Emsworth
How much electricity do solar panels make in Emsworth?
About 7,290 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Emsworth: 1,146 kWh per kWp, or 3.14 peak sun hours a day on average. July is the strongest month, at about 910 kWh.
Is solar more expensive in Emsworth?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Emsworth, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 7,290 kWh a year here, which is what drives payback.
Which DNO covers Emsworth, and what does it need from me?
Scottish and Southern Electricity Networks (SSEN) covers Emsworth. 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 Emsworth?
On the 12p export scenario, a 12-panel system in Emsworth sends about 6,352 kWh a year to the grid, worth around £762. The export rates table compares what each supplier pays.
How much solar does Emsworth get in December?
December is the low point: about 260 kWh from a 12-panel system in Emsworth, on PVGIS data, rising to 910 kWh in July. From November to February the same system makes about 1,230 kWh in total, which is why a battery charged off-peak does more of the work in winter.
