How Worthing compares
Worthing is one of 33 Sussex towns we track, and it ranks 15th of 33 for solar yield. The House of Commons Library settlement data classes it as a large town of 113,497 people. At 1,143 kWh per kWp a year, a typical 12 panel system here pays for itself in around 6.3 years on the 12p scenario: £1,006 of year one benefit against £6,360 installed, £247 of that benefit from cutting 26.32p imports with your own generation.
These are starting numbers, not a quote. The calculator below opens on Worthing'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 in Worthing go to its own council, and the House of Commons Library classes it as a large 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 Worthing's own coordinates (50.82522, -0.39582), 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.
Who runs the grid in Worthing
Worthing sits in UK Power Networks' South East England licence area, so UK Power Networks is the network operator (DNO) any solar panels or battery here are registered with.
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.
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 Worthing
A heat pump in Worthing
A heat pump does most of its work from November to February. Over those four months, 12 panels in Worthing make about 1,180 kWh, against 3,510 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 Worthing
A 12-panel roof in Worthing makes about 920 kWh in July. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
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.

Worthing solar questions
What does a solar panel system produce in Worthing?
Each kWp of panels in Worthing makes 1,143 kWh a year on PVGIS figures, so a typical 12-panel system produces around 7,270 kWh, from about 250 kWh in December up to 920 kWh in July.
How much are solar panels in Worthing?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Worthing before a battery. What Worthing changes is the return, about 7,270 kWh a year from that system, and your design call prices your actual roof.
Would a system in Worthing need approval from the network operator?
Worthing 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 can I earn from exporting solar in Worthing?
With typical use and no battery, a 12-panel system in Worthing exports about 6,333 kWh a year. At 12p per kWh that is roughly £760; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Is solar worth it in Worthing in winter?
It works, but the year is lopsided. 69% of a Worthing roof's output lands between April and September; the four months from November to February give about 1,180 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Worthing compares with its neighbours
How the towns nearest Worthing compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Worthing |
|---|---|---|
| Worthing | 1,143 | this town |
| Lancing and Sompting | 1,144 | +1 kWh |
| Rustington | 1,140 | −3 kWh |
| Shoreham-by-Sea | 1,145 | +2 kWh |
| Littlehampton | 1,137 | −6 kWh |
| Wick | 1,137 | −6 kWh |
| Storrington | 1,126 | −17 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.
