How Rogerstone compares
Small towns rarely get published solar figures, so here are the numbers for Rogerstone. It is one of 16 Monmouthshire towns we track, and it ranks 5th of 16 for solar yield, a town of 7,652 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,016 kWh per kWp a year, 2.78 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £910 of year one benefit, £247 of it from your own generation and £663 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 Rogerstone's own yield.
Rogerstone sits within Newport, its local planning authority, and the House of Commons Library classes it 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.

Connecting solar to the Rogerstone network
On NESO's licence-area map, Rogerstone 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.
Anything bigger is a G99 case and is applied for first. 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 Rogerstone
A heat pump in Rogerstone
Solar and a heat pump pull in opposite directions through the year: Rogerstone's roofs make 1,060 kWh from November to February on a 12-panel system, and 3,110 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Rogerstone
From April to September, 69% of a Rogerstone roof's yearly output arrives, peaking at about 810 kWh in May on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
If you rent, or own a flat, and have private off-street parking, the government chargepoint grant covers 75% of the cost, capped at £500 a socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above prices a 7.4kW smart charger from £1,100 installed.

Common questions about solar in Rogerstone
What could a roof in Rogerstone generate?
PVGIS puts a roof in Rogerstone at 1,016 kWh per kWp a year, 2.78 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,460 kWh a year, most of it between April and September.
What would 12 solar panels cost in Rogerstone?
£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 Rogerstone differs is output: about 6,460 kWh a year from that system.
Do I need permission from the DNO for solar in Rogerstone?
Usually not in advance. NGED, the network operator for Rogerstone, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval first. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. "See our DNO explainer.
How much would export pay on a system in Rogerstone?
It is exported. With typical use and no battery, about 5,525 kWh of the 6,460 kWh a 12-panel system makes in Rogerstone goes to the grid, around £663 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Do solar panels work in winter in Rogerstone?
Yes, at a lower level. PVGIS gives Rogerstone 33.7 kWh per kWp in December and 36.5 in January, so a 12-panel system makes about 210 kWh and 230 kWh in those months, against 810 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Rogerstone compares with its neighbours
How the towns nearest Rogerstone compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Rogerstone |
|---|---|---|
| Rogerstone | 1,016 | this town |
| Risca | 991 | −25 kWh |
| Newport | 1,029 | +13 kWh |
| Cwmbrân | 1,022 | +6 kWh |
| Newbridge | 999 | −17 kWh |
| Pontllanfraith | 988 | −28 kWh |
| Pontypool | 993 | −23 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.
