Against Great Britain as a whole: Peacehaven makes 1,158 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Peacehaven is 25% above it.
How Peacehaven compares
Small towns rarely get published solar figures, so here are the numbers for Peacehaven. It is one of 33 Sussex towns we track, and it ranks joint 7th of 33 for solar yield, a town of 16,350 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,158 kWh per kWp a year, 3.17 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £1,018 of year one benefit, £247 of it from your own generation and £771 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Peacehaven'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.
Lewes is the planning authority covering Peacehaven, 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 Peacehaven
UK Power Networks owns and runs the local electricity network in Peacehaven, as part of its South East England licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means UK Power Networks is notified within 28 days of switch-on rather than asked beforehand.
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 Peacehaven
A heat pump in Peacehaven
A heat pump does most of its work from November to February. Over those four months, 12 panels in Peacehaven make about 1,200 kWh, against 3,560 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 Peacehaven
From April to September, 69% of a Peacehaven roof's yearly output arrives, peaking at about 930 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.
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 Peacehaven
What does a solar panel system produce in Peacehaven?
Each kWp of panels in Peacehaven makes 1,158 kWh a year on PVGIS figures, so a typical 12-panel system produces around 7,360 kWh, from about 260 kWh in December up to 930 kWh in July.
What would 12 solar panels cost in Peacehaven?
£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 Peacehaven differs is output: about 7,360 kWh a year from that system.
Would a system in Peacehaven need approval from the network operator?
Peacehaven 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 would export pay on a system in Peacehaven?
It is exported. With typical use and no battery, about 6,428 kWh of the 7,360 kWh a 12-panel system makes in Peacehaven goes to the grid, around £771 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 Peacehaven in winter?
It works, but the year is lopsided. 69% of a Peacehaven roof's output lands between April and September; the four months from November to February give about 1,200 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Peacehaven 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 Peacehaven |
|---|---|---|
| Peacehaven | 1,158 | this town |
| Newhaven | 1,162 | +4 kWh |
| Seaford | 1,166 | +8 kWh |
| Lewes | 1,177 | +19 kWh |
| Brighton and Hove | 1,159 | +1 kWh |
| Polegate | 1,153 | −5 kWh |
| Southwick | 1,146 | −12 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.
