How Newport compares
Newport is one of 16 Monmouthshire towns we track, and it ranks 2nd of 16 for solar yield. The House of Commons Library settlement data classes it as a large town of 138,615 people. At 1,029 kWh per kWp a year, a typical 12 panel system here pays for itself in around 6.9 years on the 12p scenario: £919 of year one benefit against £6,360 installed, £247 of that benefit from cutting 26.32p imports with your own generation.
These are starting numbers, not a quote. The calculator below opens on Newport'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.
Newport is its own local planning authority area, and its House of Commons Library settlement class is large 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 Newport's own coordinates (51.5808, -2.98198), 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 Newport
Newport sits in National Grid Electricity Distribution's South Wales 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.
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.

Adding a heat pump or an EV charger in Newport
A heat pump in Newport
Heating demand peaks when solar is weakest. In Newport, a 12-panel system makes about 210 kWh in December and 230 kWh in January, a fraction of its 820 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 Newport
Summer is where a car earns its place. In May, 12 panels in Newport make about 820 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.
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.

Common questions about solar in Newport
How much energy would 12 solar panels make in Newport?
Newport averages 2.82 peak sun hours a day, which PVGIS turns into 1,029 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,540 kWh, 69% of it between April and September.
What does a typical solar system cost in Newport?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Newport, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,540 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Newport, 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 Newport?
Around £673 a year at 12p per kWh, for the roughly 5,608 kWh a 12-panel system in Newport 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 Newport in the winter months?
December is the weakest month in Newport: about 210 kWh from 12 panels, against 820 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Newport compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Newport.
| Town | kWh per kWp a year | vs Newport |
|---|---|---|
| Newport | 1,029 | this town |
| Rogerstone | 1,016 | −13 kWh |
| Cwmbrân | 1,022 | −7 kWh |
| Risca | 991 | −38 kWh |
| Pontypool | 993 | −36 kWh |
| Newbridge | 999 | −30 kWh |
| Caldicot | 1,023 | −6 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.
