How Pencoed compares
Small towns rarely get published solar figures, so here are the numbers for Pencoed. It is one of 32 Glamorgan towns we track, and it ranks 9th of 32 for solar yield, a town of 9,047 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,051 kWh per kWp a year, 2.88 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £937 of year one benefit, £247 of it from your own generation and £690 from export at 12p.
Every figure here assumes a clear, south-facing roof at 35 degrees. Yours will differ, which is what the free design call is for; until then, the calculator below tests panels, batteries and export rates on Pencoed's own yield.
Bridgend is the planning authority covering Pencoed, which the House of Commons Library classes 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.

Who runs the grid in Pencoed
On NESO's licence-area map, Pencoed is in South Wales, which National Grid Electricity Distribution (NGED) operates. That makes NGED the network operator for any system fitted here.
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.
A bigger inverter or battery output needs a G99 application in advance. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Beyond the panels: heating and car charging in Pencoed
A heat pump in Pencoed
A heat pump does most of its work from November to February. Over those four months, 12 panels in Pencoed make about 1,080 kWh, against 3,210 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
In Wales, 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 Pencoed
A 12-panel roof in Pencoed makes about 850 kWh in May. 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.

Solar in Pencoed: your questions answered
What does a solar panel system produce in Pencoed?
Each kWp of panels in Pencoed makes 1,051 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,680 kWh, from about 210 kWh in December up to 850 kWh in May.
What would 12 solar panels cost in Pencoed?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Pencoed differs is output: about 6,680 kWh a year from that system.
Would a system in Pencoed need approval from the network operator?
Pencoed is on National Grid Electricity Distribution's network (South Wales licence area). Systems up to 3.68kW per phase of inverter output follow G98: NGED is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. Our G98 vs G99 guide explains both routes.
How much would export pay on a system in Pencoed?
It is exported. With typical use and no battery, about 5,748 kWh of the 6,680 kWh a 12-panel system makes in Pencoed goes to the grid, around £690 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Is solar worth it in Pencoed in winter?
It works, but the year is lopsided. 69% of a Pencoed roof's output lands between April and September; the four months from November to February give about 1,080 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Pencoed 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 Pencoed |
|---|---|---|
| Pencoed | 1,051 | this town |
| Llanharan and Brynna | 1,044 | −7 kWh |
| Bridgend | 1,057 | +6 kWh |
| Sarn, Tondu and Bryncethin | 1,058 | +7 kWh |
| Tonyrefail | 991 | −60 kWh |
| Tonypandy | 956 | −95 kWh |
| Porth | 961 | −90 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.
