Against Great Britain as a whole: Wellington makes 1,008 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Wellington is 9% above it.
How Wellington compares
Small towns rarely get published solar figures, so here are the numbers for Wellington. It is one of 21 Somerset towns we track, and it ranks joint 18th of 21 for solar yield, a town of 14,561 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,008 kWh per kWp a year, 2.76 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £904 of year one benefit, £247 of it from your own generation and £657 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Wellington'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.
Any planning application in Wellington sits with Somerset, and its official House of Commons Library settlement class is 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 Wellington's own coordinates (50.97898, -3.2288), 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.
The network operator for Wellington
Wellington sits in National Grid Electricity Distribution's South West England licence area, so NGED 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, NGED only has to be told within 28 days after the system is commissioned.
Above that, G99 means applying before the work is booked. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Heat pumps and EV charging in Wellington
A heat pump in Wellington
Heating demand peaks when solar is weakest. In Wellington, a 12-panel system makes about 220 kWh in December and 240 kWh in January, a fraction of its 790 kWh in May, which is why a heat pump here is costed on its tariff first.
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 Wellington
Wellington's May output, about 790 kWh from 12 panels, is several times the 70 kWh or so a typical home uses in daylight that month on our calculator's settings. Daytime charging turns that surplus into miles.
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.

If a system in Wellington is underperforming, start with the guides below: repair benchmarks, service scope, and the inverter question.
Solar in Wellington: your questions answered
How much energy would 12 solar panels make in Wellington?
Wellington averages 2.76 peak sun hours a day, which PVGIS turns into 1,008 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,410 kWh, 68% of it between April and September.
Is solar more expensive in Wellington?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Wellington, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,410 kWh a year here, which is what drives payback.
Who is the network operator in Wellington, and do I need a G99 application?
The operator is National Grid Electricity Distribution (NGED). Most home systems use the G98 route, a notification within 28 days of switch-on for up to 3.68kW per phase, so nothing waits on the network. Above that, G99 applies and has to be granted first. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. Your design call checks which route yours needs.
What could I earn from exporting in Wellington?
On the 12p export scenario, a 12-panel system in Wellington sends about 5,474 kWh a year to the grid, worth around £657. The export rates table compares what each supplier pays.
How does solar perform in Wellington in the winter months?
December is the weakest month in Wellington: about 220 kWh from 12 panels, against 790 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Wellington compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Wellington.
| Town | kWh per kWp a year | vs Wellington |
|---|---|---|
| Wellington | 1,008 | this town |
| Taunton | 1,026 | +18 kWh |
| Cullompton | 1,026 | +18 kWh |
| Tiverton | 1,017 | +9 kWh |
| Honiton | 1,060 | +52 kWh |
| Chard | 1,050 | +42 kWh |
| Bridgwater | 1,047 | +39 kWh |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.
