How Northfleet compares
Among the places we publish figures for, Northfleet is one of 44 Kent towns we track, and it ranks 27th of 44 for solar yield. It is a medium town in the House of Commons Library classification, with 31,997 residents, and its roofs see 2.88 peak sun hours a day across the year. That drives the standard 12 panel model to 6,691 kWh of generation, of which around 5,754 kWh is exported at 12p for £690 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 Northfleet's own yield.
Any planning application in Northfleet sits with Gravesham, 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 Northfleet's own coordinates (51.43706, 0.34076), 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 Northfleet connection
Northfleet is served by UK Power Networks: the town's centre falls inside its South East England licence area on NESO's boundary map.
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: UK Power Networks is notified within 28 days of commissioning and nothing has to be approved first.
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 Northfleet
A heat pump in Northfleet
In December, the darkest month here, 12 panels in Northfleet make about 240 kWh. That is when a heat pump runs hardest, so its running cost in Northfleet comes down to the tariff and the flow temperature rather 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 Northfleet
Summer is where a car earns its place. In July, 12 panels in Northfleet make about 830 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).

Solar panel servicing and repair in Northfleet
If a system in Northfleet is underperforming, start with the guides below: repair benchmarks, service scope, and the inverter question.
Common questions about solar in Northfleet
How much energy would 12 solar panels make in Northfleet?
Northfleet averages 2.88 peak sun hours a day, which PVGIS turns into 1,052 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,690 kWh, 68% of it between April and September.
What does a typical solar system cost in Northfleet?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Northfleet, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,690 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Northfleet, 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 Northfleet?
Around £690 a year at 12p per kWh, for the roughly 5,754 kWh a 12-panel system in Northfleet 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 Northfleet in the winter months?
December is the weakest month in Northfleet: about 240 kWh from 12 panels, against 830 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Northfleet compares with its neighbours

| Longfield, New Ash Green and Hartley | 1,049 | −3 kWh |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.

Do solar panels need direct sunlight? Not really, and here is why
No. Solar cells respond to light hitting them, not to a clear line of sight to the sun.
