How South Hayling compares
Small towns rarely get published solar figures, so here are the numbers for South Hayling. It is one of 45 Hampshire towns we track, and it ranks 8th of 45 for solar yield, a town of 15,387 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,127 kWh per kWp a year, 3.09 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £995 of year one benefit, £247 of it from your own generation and £748 from export at 12p.
Every figure here assumes a clear, south-facing roof at 35 degrees. Yours will differ, which is what the free design call is for; until then, the calculator below tests panels, batteries and export rates on South Hayling's own yield.
South Hayling sits within Havant, its local planning authority, and the House of Commons Library classes it 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.

Connecting solar to the South Hayling network
Scottish and Southern Electricity Networks (SSEN) owns and runs the local electricity network in South Hayling, as part of its Southern England licence area.
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.
A bigger inverter or battery output needs a G99 application in advance. 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.

Beyond the panels: heating and car charging in South Hayling
A heat pump in South Hayling
Solar and a heat pump pull in opposite directions through the year: South Hayling's roofs make 1,190 kWh from November to February on a 12-panel system, and 3,430 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 South Hayling
From April to September, 68% of a South Hayling roof's yearly output arrives, peaking at about 900 kWh in July on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
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 South Hayling: your questions answered
What could a roof in South Hayling generate?
PVGIS puts a roof in South Hayling at 1,127 kWh per kWp a year, 3.09 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 7,170 kWh a year, most of it between April and September.
How much are solar panels in South Hayling?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in South Hayling before a battery. What South Hayling changes is the return, about 7,170 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in South Hayling?
Usually not in advance. SSEN, the network operator for South Hayling, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval 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. "See our DNO explainer.
How much can I earn from exporting solar in South Hayling?
With typical use and no battery, a 12-panel system in South Hayling exports about 6,231 kWh a year. At 12p per kWh that is roughly £748; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in South Hayling?
Yes, at a lower level. PVGIS gives South Hayling 39 kWh per kWp in December and 41.6 in January, so a 12-panel system makes about 250 kWh and 260 kWh in those months, against 900 kWh in July. Winter output mostly covers daytime use rather than exporting.
