How Tonypandy compares
Small towns rarely get published solar figures, so here are the numbers for Tonypandy. It is one of 32 Glamorgan towns we track, and it ranks 25th of 32 for solar yield, a town of 17,237 people in the House of Commons Library settlement data. PVGIS gives its roofs 956 kWh per kWp a year, 2.62 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £864 of year one benefit, £247 of it from your own generation and £617 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Tonypandy'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.
Rhondda Cynon Taf is the planning authority covering Tonypandy, which the House of Commons Library classes 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.

Generation is modelled from PVGIS satellite data for Tonypandy's own coordinates (51.61722, -3.45082), 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.
Who runs the grid in Tonypandy
National Grid Electricity Distribution (NGED) owns and runs the local electricity network in Tonypandy, as part of its South Wales licence area.
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.
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.

Heat pumps and EV charging in Tonypandy
A heat pump in Tonypandy
A heat pump does most of its work from November to February. Over those four months, 12 panels in Tonypandy make about 950 kWh, against 2,930 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Tonypandy
A 12-panel roof in Tonypandy makes about 780 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).

Tonypandy solar questions
What does a solar panel system produce in Tonypandy?
Each kWp of panels in Tonypandy makes 956 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,080 kWh, from about 190 kWh in December up to 780 kWh in May.
How much are solar panels in Tonypandy?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Tonypandy before a battery. What Tonypandy changes is the return, about 6,080 kWh a year from that system, and your design call prices your actual roof.
Would a system in Tonypandy need approval from the network operator?
Tonypandy is on National Grid Electricity Distribution's network (South Wales licence area). Systems up to 3.68kW per phase of inverter output follow G98: NGED is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. Our G98 vs G99 guide explains both routes.
How much can I earn from exporting solar in Tonypandy?
With typical use and no battery, a 12-panel system in Tonypandy exports about 5,143 kWh a year. At 12p per kWh that is roughly £617; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Is solar worth it in Tonypandy in winter?
It works, but the year is lopsided. 69% of a Tonypandy roof's output lands between April and September; the four months from November to February give about 950 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Tonypandy 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 Tonypandy |
|---|---|---|
| Tonypandy | 956 | this town |
| Porth | 961 | +5 kWh |
| Rhondda | 882 | −74 kWh |
| Tonyrefail | 991 | +35 kWh |
| Treorchy | 925 | −31 kWh |
| Mountain Ash | 948 | −8 kWh |
| Pontypridd | 997 | +41 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.
