Against Great Britain as a whole: Gowerton makes 1,063 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Gowerton is 15% above it.
How Gowerton compares
Small towns rarely get published solar figures, so here are the numbers for Gowerton. It is one of 32 Glamorgan towns we track, and it ranks 1st of 32 for solar yield, a town of 7,643 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,063 kWh per kWp a year, 2.91 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £946 of year one benefit, £247 of it from your own generation and £699 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Gowerton'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 Swansea; nationally, the House of Commons Library classes Gowerton 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.

NGED and your Gowerton connection
Gowerton is served by National Grid Electricity Distribution (NGED): the town's centre falls inside its South Wales licence area on NESO's boundary map.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to NGED within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
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.

Adding a heat pump or an EV charger in Gowerton
A heat pump in Gowerton
In December, the darkest month here, 12 panels in Gowerton make about 210 kWh. That is when a heat pump runs hardest, so its running cost in Gowerton comes down to the tariff and the flow temperature rather 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 Gowerton
Gowerton's May output, about 860 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.
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.

Solar panel servicing and repair in Gowerton
If a system in Gowerton is underperforming, start with the guides below: repair benchmarks, service scope, and the inverter question.
Gowerton solar questions
How much energy would 12 solar panels make in Gowerton?
Gowerton averages 2.91 peak sun hours a day, which PVGIS turns into 1,063 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,760 kWh, 69% of it between April and September.
Is solar more expensive in Gowerton?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Gowerton, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,760 kWh a year here, which is what drives payback.
Who is the network operator in Gowerton, 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 Gowerton?
On the 12p export scenario, a 12-panel system in Gowerton sends about 5,824 kWh a year to the grid, worth around £699. The export rates table compares what each supplier pays.
How does solar perform in Gowerton in the winter months?
December is the weakest month in Gowerton: about 210 kWh from 12 panels, against 860 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Gowerton 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 Gowerton |
|---|---|---|
| Gowerton | 1,063 | this town |
| Gorseinon | 1,040 | −23 kWh |
| Swansea | 1,023 | −40 kWh |
| Llanelli | 1,064 | +1 kWh |
| Clydach | 981 | −82 kWh |
| Neath | 996 | −67 kWh |
| Baglan | 1,027 | −36 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.
