Against Great Britain as a whole: Montgomeryshire makes 935 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Montgomeryshire is 1% above it.
How Montgomeryshire compares
Montgomeryshire ranks joint 43rd of the 85 counties we track for solar yield. Self use does the heavy lifting here: of the £848 year one benefit on a typical 12 panel system, £247 comes from replacing 26.32p imports with your own generation, which is why battery sizing matters more than panel count.
These are county-level starting numbers. A town page gives the figure for its own centroid, and your design call replaces both with your roof, its shading and your bills.
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.

Import valued at 26.32p/kWh (Ofgem price cap average, Oct to Dec 2026); off-peak charging at 8.5p/kWh where used (a supplier's published off-peak rate, checked September 2026); export at the scenario you pick, from the dated tariff table. Prices are installed pricing, August 2026, standard installations; 530W LONGi panels at £1,000 per kWp. Estimates for illustration, not a quote: your free design call prices your actual roof.
Who runs the grid in Montgomeryshire
SP Energy Networks is the distribution network operator (DNO) for Montgomeryshire, running its North Wales, Merseyside and Cheshire licence area.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to SP Energy Networks within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
A bigger inverter or battery output needs a G99 application in advance. 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.

Adding a heat pump or an EV charger in Montgomeryshire
A heat pump in Montgomeryshire
A heat pump does most of its work from November to February. Over those four months, 12 panels in Montgomeryshire make about 930 kWh, against 2,890 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Montgomeryshire
A 12-panel roof in Montgomeryshire makes about 760 kWh in May. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
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).

Common questions about solar in Montgomeryshire
What does a solar panel system produce in Montgomeryshire?
Each kWp of panels in Montgomeryshire makes 935 kWh a year on PVGIS figures, so a typical 12-panel system produces around 5,950 kWh, from about 180 kWh in December up to 760 kWh in May.
What would 12 solar panels cost in Montgomeryshire?
£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 Montgomeryshire differs is output: about 5,950 kWh a year from that system.
Would a system in Montgomeryshire need approval from the network operator?
Montgomeryshire is on SP Energy Networks' network (North Wales, Merseyside and Cheshire licence area). Systems up to 3.68kW per phase of inverter output follow G98: SP Energy Networks is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. 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. Our G98 vs G99 guide explains both routes.
How much would export pay on a system in Montgomeryshire?
It is exported. With typical use and no battery, about 5,010 kWh of the 5,950 kWh a 12-panel system makes in Montgomeryshire goes to the grid, around £601 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Is solar worth it in Montgomeryshire in winter?
It works, but the year is lopsided. 70% of a Montgomeryshire roof's output lands between April and September; the four months from November to February give about 930 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
