How Brecon compares
Small towns rarely get published solar figures, so here are the numbers for Brecon. It is the only Brecknockshire town we track so far, with county rankings to follow as its neighbours land, a town of 8,350 people in the House of Commons Library settlement data. PVGIS gives its roofs 922 kWh per kWp a year, 2.53 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £838 of year one benefit, £247 of it from your own generation and £591 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Brecon'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.
Planning applications here go through Powys; nationally, the House of Commons Library classes Brecon 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.

The network operator for Brecon
Brecon is served by National Grid Electricity Distribution (NGED): the town's centre falls inside its South Wales licence area on NESO's boundary map.
What decides the paperwork is the inverter and battery output, not the number of panels. Up to 3.68kW per phase, a system follows G98: NGED is notified within 28 days of commissioning and nothing has to be approved first.
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 Brecon
A heat pump in Brecon
In December, the darkest month here, 12 panels in Brecon make about 180 kWh. That is when a heat pump runs hardest, so its running cost in Brecon comes down to the tariff and the flow temperature rather 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 Brecon
Summer is where a car earns its place. In May, 12 panels in Brecon make about 740 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).

Brecon solar questions
How much electricity do solar panels make in Brecon?
About 5,860 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Brecon: 922 kWh per kWp, or 2.53 peak sun hours a day on average. May is the strongest month, at about 740 kWh.
What does a typical solar system cost in Brecon?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Brecon, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 5,860 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Brecon, and what does it need from me?
National Grid Electricity Distribution (NGED) covers Brecon. A home system of up to 3.68kW per phase is notified to NGED within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.
What happens to the solar I do not use in Brecon?
Around £591 a year at 12p per kWh, for the roughly 4,927 kWh a 12-panel system in Brecon exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Brecon get in December?
December is the low point: about 180 kWh from a 12-panel system in Brecon, on PVGIS data, rising to 740 kWh in May. From November to February the same system makes about 910 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Brecon compares with its neighbours
