How Folkestone compares
Among the places we publish figures for, Folkestone is one of 44 Kent towns we track, and it ranks 1st of 44 for solar yield. It is a medium town in the House of Commons Library classification, with 53,744 residents, and its roofs see 3.10 peak sun hours a day across the year. That drives the standard 12 panel model to 7,200 kWh of generation, of which around 6,263 kWh is exported at 12p for £752 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
These are starting numbers, not a quote. The calculator below opens on Folkestone's own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Folkestone and Hythe is the planning authority covering Folkestone, which the House of Commons Library classes as a 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.

Who runs the grid in Folkestone
Folkestone 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.
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.

Adding a heat pump or an EV charger in Folkestone
A heat pump in Folkestone
A heat pump does most of its work from November to February. Over those four months, 12 panels in Folkestone make about 1,130 kWh, against 3,490 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 Folkestone
A 12-panel roof in Folkestone makes about 910 kWh in July. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
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).

Folkestone solar questions
What does a solar panel system produce in Folkestone?
Each kWp of panels in Folkestone makes 1,132 kWh a year on PVGIS figures, so a typical 12-panel system produces around 7,200 kWh, from about 240 kWh in December up to 910 kWh in July.
How much are solar panels in Folkestone?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Folkestone before a battery. What Folkestone changes is the return, about 7,200 kWh a year from that system, and your design call prices your actual roof.
Would a system in Folkestone need approval from the network operator?
Folkestone 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 can I earn from exporting solar in Folkestone?
With typical use and no battery, a 12-panel system in Folkestone exports about 6,263 kWh a year. At 12p per kWh that is roughly £752; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Is solar worth it in Folkestone in winter?
It works, but the year is lopsided. 70% of a Folkestone roof's output lands between April and September; the four months from November to February give about 1,130 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Folkestone compares with its neighbours
Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.
| Town | kWh per kWp a year | vs Folkestone |
|---|---|---|
| Folkestone | 1,132 | this town |
| Hawkinge | 1,126 | −6 kWh |
| Hythe | 1,109 | −23 kWh |
| Dover | 1,112 | −20 kWh |
| Ashford | 1,120 | −12 kWh |
| Deal | 1,127 | −5 kWh |
| Canterbury | 1,094 | −38 kWh |
Each row is a PVGIS v5.2 run at that town's centre with the same settings. Treat gaps of a few kWh as noise and gaps over about 30 kWh per kWp as real differences in sunshine.
