How Newtown compares
Small towns rarely get published solar figures, so here are the numbers for Newtown. It is the only Montgomeryshire town we track so far, with county rankings to follow as its neighbours land, a town of 11,087 people in the House of Commons Library settlement data. PVGIS gives its roofs 912 kWh per kWp a year, 2.50 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £831 of year one benefit, £247 of it from your own generation and £584 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 Newtown's own yield.
Newtown sits within Powys, 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 Newtown network
SP Energy Networks owns and runs the local electricity network in Newtown, as part of its North Wales, Merseyside and Cheshire licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means SP Energy Networks is notified within 28 days of switch-on rather than asked beforehand.
Anything bigger is a G99 case and is applied for first. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds SP Energy Networks as it does every network operator.

Beyond the panels: heating and car charging in Newtown
A heat pump in Newtown
Solar and a heat pump pull in opposite directions through the year: Newtown's roofs make 850 kWh from November to February on a 12-panel system, and 2,840 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 Newtown
From April to September, 70% of a Newtown roof's yearly output arrives, peaking at about 740 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.

Solar in Newtown: your questions answered
What could a roof in Newtown generate?
PVGIS puts a roof in Newtown at 912 kWh per kWp a year, 2.50 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 5,800 kWh a year, most of it between April and September.
How much are solar panels in Newtown?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Newtown before a battery. What Newtown changes is the return, about 5,800 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Newtown?
Usually not in advance. SP Energy Networks, the network operator for Newtown, 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. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds SP Energy Networks as it does every network operator. "See our DNO explainer.
How much can I earn from exporting solar in Newtown?
With typical use and no battery, a 12-panel system in Newtown exports about 4,864 kWh a year. At 12p per kWh that is roughly £584; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in Newtown?
Yes, at a lower level. PVGIS gives Newtown 24.2 kWh per kWp in December and 27.1 in January, so a 12-panel system makes about 150 kWh and 170 kWh in those months, against 740 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Newtown 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 Newtown |
|---|---|---|
| Newtown | 912 | this town |
| Croesoswallt | 968 | +56 kWh |
| Ludlow | 970 | +58 kWh |
| Shrewsbury | 969 | +57 kWh |
| Leominster | 984 | +72 kWh |
| Aberystwyth | 947 | +35 kWh |
| Rhosllannerchrugog | 957 | +45 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.
