How Abertillery compares
Small towns rarely get published solar figures, so here are the numbers for Abertillery. It is one of 16 Monmouthshire towns we track, and it ranks 15th of 16 for solar yield, a town of 10,337 people in the House of Commons Library settlement data. PVGIS gives its roofs 947 kWh per kWp a year, 2.59 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £857 of year one benefit, £247 of it from your own generation and £610 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 Abertillery's own yield.
Any planning application in Abertillery sits with Blaenau Gwent, 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.

The network operator for Abertillery
Abertillery 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.
Larger systems go through G99 instead, applied for before installation. On timing: 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 Abertillery
A heat pump in Abertillery
Heating demand peaks when solar is weakest. In Abertillery, a 12-panel system makes about 180 kWh in December and 190 kWh in January, a fraction of its 770 kWh in May, which is why a heat pump here is costed on its tariff first.
Grant support in Wales comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Abertillery
Summer is where a car earns its place. In May, 12 panels in Abertillery make about 770 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Solar in Abertillery: your questions answered
How much electricity do solar panels make in Abertillery?
About 6,020 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Abertillery: 947 kWh per kWp, or 2.59 peak sun hours a day on average. May is the strongest month, at about 770 kWh.
What does a typical solar system cost in Abertillery?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Abertillery, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,020 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Abertillery, and what does it need from me?
National Grid Electricity Distribution (NGED) covers Abertillery. A home system of up to 3.68kW per phase is notified to NGED within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.
What happens to the solar I do not use in Abertillery?
Around £610 a year at 12p per kWh, for the roughly 5,086 kWh a 12-panel system in Abertillery exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Abertillery get in December?
December is the low point: about 180 kWh from a 12-panel system in Abertillery, on PVGIS data, rising to 770 kWh in May. From November to February the same system makes about 910 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Abertillery 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 Abertillery |
|---|---|---|
| Abertillery | 947 | this town |
| Abersychan | 958 | +11 kWh |
| Newbridge | 999 | +52 kWh |
| Pontypool | 993 | +46 kWh |
| Ebbw Vale | 945 | −2 kWh |
| Blackwood | 987 | +40 kWh |
| Bargod | 985 | +38 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.

What the January price cap means for solar, and what it does not
The whole-bill forecast is gas-led. What solar actually competes with is smaller, and mostly unpublished.

No panels means one job: buy cheap, use later. The tariff decides whether it pays.

Three phase buys 22kW charging. Most cars cannot use it, and load balancing usually solves the real problem.
