How Newhaven compares
Small towns rarely get published solar figures, so here are the numbers for Newhaven. It is one of 33 Sussex towns we track, and it ranks 4th of 33 for solar yield, a town of 13,583 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,162 kWh per kWp a year, 3.18 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £1,021 of year one benefit, £247 of it from your own generation and £774 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Newhaven'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.
Newhaven sits within Lewes, its local planning authority, and the House of Commons Library classes it 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.

Generation is modelled from PVGIS satellite data for Newhaven's own coordinates (50.79455, 0.05152), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate; the methodology is on our help page.
Connecting solar to the Newhaven network
UK Power Networks owns and runs the local electricity network in Newhaven, 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.
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.

Adding a heat pump or an EV charger in Newhaven
A heat pump in Newhaven
Solar and a heat pump pull in opposite directions through the year: Newhaven's roofs make 1,200 kWh from November to February on a 12-panel system, and 3,570 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Newhaven
From April to September, 69% of a Newhaven 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.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Common questions about solar in Newhaven
What could a roof in Newhaven generate?
PVGIS puts a roof in Newhaven at 1,162 kWh per kWp a year, 3.18 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 7,390 kWh a year, most of it between April and September.
How much are solar panels in Newhaven?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Newhaven before a battery. What Newhaven changes is the return, about 7,390 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Newhaven?
Usually not in advance. UK Power Networks, the network operator for Newhaven, 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 can I earn from exporting solar in Newhaven?
With typical use and no battery, a 12-panel system in Newhaven exports about 6,454 kWh a year. At 12p per kWh that is roughly £774; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in Newhaven?
Yes, at a lower level. PVGIS gives Newhaven 39.6 kWh per kWp in December and 42.3 in January, so a 12-panel system makes about 250 kWh and 270 kWh in those months, against 930 kWh in July. Winter output mostly covers daytime use rather than exporting.
How Newhaven compares with its neighbours
How the towns nearest Newhaven compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Newhaven |
|---|---|---|
| Newhaven | 1,162 | this town |
| Peacehaven | 1,158 | −4 kWh |
| Seaford | 1,166 | +4 kWh |
| Lewes | 1,177 | +15 kWh |
| Polegate | 1,153 | −9 kWh |
| Brighton and Hove | 1,159 | −3 kWh |
| Eastbourne | 1,160 | −2 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.
