How Sittingbourne compares
Among the places we publish figures for, Sittingbourne is one of 44 Kent towns we track, and it ranks 18th of 44 for solar yield. It is a medium town in the House of Commons Library classification, with 56,933 residents, and its roofs see 2.94 peak sun hours a day across the year. That drives the standard 12 panel model to 6,824 kWh of generation, of which around 5,888 kWh is exported at 12p for £707 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 Sittingbourne's own yield.
Any planning application in Sittingbourne sits with Swale, and its official House of Commons Library settlement class is medium 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 Sittingbourne's own coordinates (51.34663, 0.73956), 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.
UK Power Networks and your Sittingbourne connection
Sittingbourne is served by UK Power Networks: the town's centre falls inside its South East England licence area on NESO's boundary map.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to UK Power Networks within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
Larger systems go through G99 instead, applied for before installation. On timing: 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 Sittingbourne
A heat pump in Sittingbourne
Heating demand peaks when solar is weakest. In Sittingbourne, a 12-panel system makes about 250 kWh in December and 260 kWh in January, a fraction of its 840 kWh in July, which is why a heat pump here is costed on its tariff first.
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 Sittingbourne
Summer is where a car earns its place. In July, 12 panels in Sittingbourne make about 840 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).

Common questions about solar in Sittingbourne
How much energy would 12 solar panels make in Sittingbourne?
Sittingbourne averages 2.94 peak sun hours a day, which PVGIS turns into 1,073 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,820 kWh, 68% of it between April and September.
What does a typical solar system cost in Sittingbourne?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Sittingbourne, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,820 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Sittingbourne, and do I need a G99 application?
The operator is UK Power Networks. 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. 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. Your design call checks which route yours needs.
What happens to the solar I do not use in Sittingbourne?
Around £707 a year at 12p per kWh, for the roughly 5,888 kWh a 12-panel system in Sittingbourne exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How does solar perform in Sittingbourne in the winter months?
December is the weakest month in Sittingbourne: about 250 kWh from 12 panels, against 840 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
