How Newbridge compares
Small towns rarely get published solar figures, so here are the numbers for Newbridge. It is one of 16 Monmouthshire towns we track, and it ranks 6th of 16 for solar yield, a town of 7,704 people in the House of Commons Library settlement data. PVGIS gives its roofs 999 kWh per kWp a year, 2.74 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £897 of year one benefit, £247 of it from your own generation and £650 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Newbridge'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 Newbridge sits with Caerphilly, 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 figures use PVGIS for the centre of Newbridge (51.67008, -3.14407), a 26.32p/kWh import price and £1,000 per kWp installed; see the help page for the full method.
NGED and your Newbridge connection
Newbridge 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.

Heat pumps and EV charging in Newbridge
A heat pump in Newbridge
Heating demand peaks when solar is weakest. In Newbridge, a 12-panel system makes about 200 kWh in December and 220 kWh in January, a fraction of its 800 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 Newbridge
Summer is where a car earns its place. In May, 12 panels in Newbridge make about 800 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 Newbridge: your questions answered
How much energy would 12 solar panels make in Newbridge?
Newbridge averages 2.74 peak sun hours a day, which PVGIS turns into 999 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,350 kWh, 69% of it between April and September.
What does a typical solar system cost in Newbridge?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Newbridge, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,350 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Newbridge, 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 happens to the solar I do not use in Newbridge?
Around £650 a year at 12p per kWh, for the roughly 5,417 kWh a 12-panel system in Newbridge exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How does solar perform in Newbridge in the winter months?
December is the weakest month in Newbridge: about 200 kWh from 12 panels, against 800 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Newbridge 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 Newbridge |
|---|---|---|
| Newbridge | 999 | this town |
| Pontllanfraith | 988 | −11 kWh |
| Blackwood | 987 | −12 kWh |
| Bargod | 985 | −14 kWh |
| Ystrad Mynach | 991 | −8 kWh |
| Abertillery | 947 | −52 kWh |
| Risca | 991 | −8 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.
