Against Great Britain as a whole: Littlehampton makes 1,137 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Littlehampton is 23% above it.
How Littlehampton compares
Small towns rarely get published solar figures, so here are the numbers for Littlehampton. It is one of 33 Sussex towns we track, and it ranks joint 19th of 33 for solar yield, a town of 19,216 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,137 kWh per kWp a year, 3.12 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £1,002 of year one benefit, £247 of it from your own generation and £755 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Littlehampton'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.
Planning applications here go through Arun; nationally, the House of Commons Library classes Littlehampton 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.

UK Power Networks and your Littlehampton connection
The distribution network operator (DNO) for Littlehampton is UK Power Networks, which runs the South East England licence area.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, UK Power Networks only has to be told within 28 days after the system is commissioned.
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.

Adding a heat pump or an EV charger in Littlehampton
A heat pump in Littlehampton
Heating demand peaks when solar is weakest. In Littlehampton, a 12-panel system makes about 250 kWh in December and 260 kWh in January, a fraction of its 920 kWh in July, which is why a heat pump here is costed on its tariff first.
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 Littlehampton
Summer is where a car earns its place. In July, 12 panels in Littlehampton make about 920 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.
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.

Littlehampton solar questions
How much electricity do solar panels make in Littlehampton?
About 7,230 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Littlehampton: 1,137 kWh per kWp, or 3.12 peak sun hours a day on average. July is the strongest month, at about 920 kWh.
What does a typical solar system cost in Littlehampton?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Littlehampton, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 7,230 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Littlehampton, and what does it need from me?
UK Power Networks covers Littlehampton. A home system of up to 3.68kW per phase is notified to UK Power Networks within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. 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.
What happens to the solar I do not use in Littlehampton?
Around £755 a year at 12p per kWh, for the roughly 6,295 kWh a 12-panel system in Littlehampton exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Littlehampton get in December?
December is the low point: about 250 kWh from a 12-panel system in Littlehampton, on PVGIS data, rising to 920 kWh in July. From November to February the same system makes about 1,180 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Littlehampton 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 Littlehampton |
|---|---|---|
| Littlehampton | 1,137 | this town |
| Wick | 1,137 | level |
| Rustington | 1,140 | +3 kWh |
| Barnham | 1,148 | +11 kWh |
| Worthing | 1,143 | +6 kWh |
| Bognor Regis | 1,141 | +4 kWh |
| Storrington | 1,126 | −11 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.
