How Selsey compares
Small towns rarely get published solar figures, so here are the numbers for Selsey. It is one of 33 Sussex towns we track, and it ranks 9th of 33 for solar yield, a town of 10,723 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,155 kWh per kWp a year, 3.17 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £1,016 of year one benefit, £247 of it from your own generation and £769 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Selsey'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 Selsey sits with Chichester, 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 Selsey's own coordinates (50.73423, -0.78943), 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.
SSEN and your Selsey connection
On NESO's licence-area map, Selsey is in Southern England, which Scottish and Southern Electricity Networks (SSEN) operates. That makes SSEN the network operator for any system fitted here.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to SSEN within 28 days of commissioning, with no prior approval.
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 Selsey
A heat pump in Selsey
In December, the darkest month here, 12 panels in Selsey make about 250 kWh. That is when a heat pump runs hardest, so its running cost in Selsey 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 Selsey
Summer is where a car earns its place. In July, 12 panels in Selsey make about 930 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.
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).

Selsey solar questions
How much electricity do solar panels make in Selsey?
About 7,350 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Selsey: 1,155 kWh per kWp, or 3.17 peak sun hours a day on average. July is the strongest month, at about 930 kWh.
What does a typical solar system cost in Selsey?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Selsey, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 7,350 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Selsey, and what does it need from me?
Scottish and Southern Electricity Networks (SSEN) covers Selsey. 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 happens to the solar I do not use in Selsey?
Around £769 a year at 12p per kWh, for the roughly 6,409 kWh a 12-panel system in Selsey exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Selsey get in December?
December is the low point: about 250 kWh from a 12-panel system in Selsey, on PVGIS data, rising to 930 kWh in July. From November to February the same system makes about 1,210 kWh in total, which is why a battery charged off-peak does more of the work in winter.
