How Felixstowe compares
Small towns rarely get published solar figures, so here are the numbers for Felixstowe. It is one of 16 Suffolk towns we track, and it ranks 5th of 16 for solar yield, a town of 24,951 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,074 kWh per kWp a year, 2.94 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £954 of year one benefit, £247 of it from your own generation and £707 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Felixstowe's own yield, and prices a 12 panel system at £6,360 installed before any battery. Your free design call reworks every number for your actual roof, its shading and your usage.
East Suffolk is the planning authority covering Felixstowe, which the House of Commons Library classes 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.

Who runs the grid in Felixstowe
On NESO's licence-area map, Felixstowe is in East England, which UK Power Networks operates. That makes UK Power Networks the network operator for any system fitted here.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to UK Power Networks within 28 days of commissioning, with no prior approval.
Anything bigger is a G99 case and is applied for 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.

Heat pumps and EV charging in Felixstowe
A heat pump in Felixstowe
A heat pump does most of its work from November to February. Over those four months, 12 panels in Felixstowe make about 1,110 kWh, against 3,280 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
In England, the Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump and £2,500 towards an air-to-air one, with £1,500 more until March 2027 for homes heated by oil or LPG with no mains gas (gov.uk, checked 28 September 2026).
Charging an EV in Felixstowe
From April to September, 69% of a Felixstowe roof's yearly output arrives, peaking at about 850 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.
If you rent, or own a flat, and have private off-street parking, the government chargepoint grant covers 75% of the cost, capped at £500 a socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above prices a 7.4kW smart charger from £1,100 installed.

Felixstowe solar questions
What does a solar panel system produce in Felixstowe?
Each kWp of panels in Felixstowe makes 1,074 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,830 kWh, from about 230 kWh in December up to 850 kWh in July.
What would 12 solar panels cost in Felixstowe?
£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 Felixstowe differs is output: about 6,830 kWh a year from that system.
Would a system in Felixstowe need approval from the network operator?
Felixstowe is on UK Power Networks' network (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 Felixstowe?
It is exported. With typical use and no battery, about 5,894 kWh of the 6,830 kWh a 12-panel system makes in Felixstowe goes to the grid, around £707 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 Felixstowe in winter?
It works, but the year is lopsided. 69% of a Felixstowe roof's output lands between April and September; the four months from November to February give about 1,110 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Felixstowe compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Felixstowe.

| Kesgrave | 1,090 | +16 kWh |
| Woodbridge | 1,095 | +21 kWh |
| Ipswich | 1,079 | +5 kWh |
| Clacton-on-Sea | 1,110 | +36 kWh |
| Brightlingsea | 1,109 | +35 kWh |
PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.

An east west split gives up about a fifth of the annual total, and can still be worth more than south.
