How Lancing and Sompting compares
Among the places we publish figures for, Lancing and Sompting is one of 33 Sussex towns we track, and it ranks 14th of 33 for solar yield. It is a medium town in the House of Commons Library classification, with 28,309 residents, and its roofs see 3.14 peak sun hours a day across the year. That drives the standard 12 panel model to 7,276 kWh of generation, of which around 6,339 kWh is exported at 12p for £761 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
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 Lancing and Sompting's own yield.

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.

Who runs the grid in Lancing and Sompting
The distribution network operator (DNO) for Lancing and Sompting is UK Power Networks, which runs the South East England licence area.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, UK Power Networks only has to be told within 28 days after the system is commissioned.
A bigger inverter or battery output needs a G99 application in advance. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds UK Power Networks as it does every network operator.

Beyond the panels: heating and car charging in Lancing and Sompting
A heat pump in Lancing and Sompting
A heat pump does most of its work from November to February. Over those four months, 12 panels in Lancing and Sompting make about 1,170 kWh, against 3,520 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Lancing and Sompting
From April to September, 69% of a Lancing and Sompting roof's yearly output arrives, peaking at about 920 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).

Common questions about solar in Lancing and Sompting
What does a solar panel system produce in Lancing and Sompting?
Each kWp of panels in Lancing and Sompting makes 1,144 kWh a year on PVGIS figures, so a typical 12-panel system produces around 7,280 kWh, from about 250 kWh in December up to 920 kWh in July.
What would 12 solar panels cost in Lancing and Sompting?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Lancing and Sompting differs is output: about 7,280 kWh a year from that system.
Would a system in Lancing and Sompting need approval from the network operator?
Lancing and Sompting is on UK Power Networks' network (South East England licence area). Systems up to 3.68kW per phase of inverter output follow G98: UK Power Networks is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds UK Power Networks as it does every network operator. Our G98 vs G99 guide explains both routes.
How much would export pay on a system in Lancing and Sompting?
It is exported. With typical use and no battery, about 6,339 kWh of the 7,280 kWh a 12-panel system makes in Lancing and Sompting goes to the grid, around £761 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Is solar worth it in Lancing and Sompting in winter?
It works, but the year is lopsided. 69% of a Lancing and Sompting roof's output lands between April and September; the four months from November to February give about 1,170 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
