Against Great Britain as a whole: Clacton-on-Sea makes 1,110 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Clacton-on-Sea is 20% above it.
How Clacton-on-Sea compares
Among the places we publish figures for, Clacton-on-Sea is one of 46 Essex towns we track, and it ranks 2nd of 46 for solar yield. It is a medium town in the House of Commons Library classification, with 55,568 residents, and its roofs see 3.04 peak sun hours a day across the year. That drives the standard 12 panel model to 7,060 kWh of generation, of which around 6,123 kWh is exported at 12p for £735 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Clacton-on-Sea'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.
Clacton-on-Sea sits within Tendring, its local planning authority, and the House of Commons Library classes it 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.

The figures use PVGIS for the centre of Clacton-on-Sea (51.80185, 1.15476), a 26.32p/kWh import price and £1,000 per kWp installed; see the help page for the full method.
Connecting solar to the Clacton-on-Sea network
Clacton-on-Sea is served by UK Power Networks: the town's centre falls inside its 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.
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 Clacton-on-Sea
A heat pump in Clacton-on-Sea
Solar and a heat pump pull in opposite directions through the year: Clacton-on-Sea's roofs make 1,160 kWh from November to February on a 12-panel system, and 3,390 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Clacton-on-Sea
From April to September, 69% of a Clacton-on-Sea roof's yearly output arrives, peaking at about 880 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.

Clacton-on-Sea solar questions
What could a roof in Clacton-on-Sea generate?
PVGIS puts a roof in Clacton-on-Sea at 1,110 kWh per kWp a year, 3.04 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 7,060 kWh a year, most of it between April and September.
What would 12 solar panels cost in Clacton-on-Sea?
£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 Clacton-on-Sea differs is output: about 7,060 kWh a year from that system.
Do I need permission from the DNO for solar in Clacton-on-Sea?
Usually not in advance. UK Power Networks, the network operator for Clacton-on-Sea, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval 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. "See our DNO explainer.
How much would export pay on a system in Clacton-on-Sea?
It is exported. With typical use and no battery, about 6,123 kWh of the 7,060 kWh a 12-panel system makes in Clacton-on-Sea goes to the grid, around £735 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Do solar panels work in winter in Clacton-on-Sea?
Yes, at a lower level. PVGIS gives Clacton-on-Sea 37.7 kWh per kWp in December and 39.6 in January, so a 12-panel system makes about 240 kWh and 250 kWh in those months, against 880 kWh in July. Winter output mostly covers daytime use rather than exporting.
How Clacton-on-Sea 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 Clacton-on-Sea |
|---|---|---|
| Clacton-on-Sea | 1,110 | this town |
| Brightlingsea | 1,109 | −1 kWh |
| Harwich | 1,092 | −18 kWh |
| Berechurch | 1,091 | −19 kWh |
| Colchester | 1,082 | −28 kWh |
| Felixstowe | 1,074 | −36 kWh |
| Ipswich | 1,079 | −31 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.
