How Maesteg compares
Small towns rarely get published solar figures, so here are the numbers for Maesteg. It is one of 32 Glamorgan towns we track, and it ranks 26th of 32 for solar yield, a town of 18,278 people in the House of Commons Library settlement data. PVGIS gives its roofs 954 kWh per kWp a year, 2.61 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £863 of year one benefit, £247 of it from your own generation and £616 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Maesteg's own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Bridgend is the planning authority covering Maesteg, 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 Maesteg's own coordinates (51.61143, -3.65381), 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 Maesteg
Maesteg 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.
A bigger inverter or battery output needs a G99 application in advance. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Adding a heat pump or an EV charger in Maesteg
A heat pump in Maesteg
A heat pump does most of its work from November to February. Over those four months, 12 panels in Maesteg make about 980 kWh, against 2,900 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
In Wales, the Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump and £2,500 towards an air-to-air one, with £1,500 more until March 2027 for homes heated by oil or LPG with no mains gas (gov.uk, checked 28 September 2026).
Charging an EV in Maesteg
From April to September, 69% of a Maesteg roof's yearly output arrives, peaking at about 780 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.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Maesteg solar questions
What does a solar panel system produce in Maesteg?
Each kWp of panels in Maesteg makes 954 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,070 kWh, from about 200 kWh in December up to 780 kWh in May.
How much are solar panels in Maesteg?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Maesteg before a battery. What Maesteg changes is the return, about 6,070 kWh a year from that system, and your design call prices your actual roof.
Would a system in Maesteg need approval from the network operator?
Maesteg 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 Maesteg?
With typical use and no battery, a 12-panel system in Maesteg exports about 5,131 kWh a year. At 12p per kWh that is roughly £616; 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 Maesteg in winter?
It works, but the year is lopsided. 69% of a Maesteg roof's output lands between April and September; the four months from November to February give about 980 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Maesteg compares with its neighbours
How the towns nearest Maesteg compare on the same PVGIS settings, closest first.

| Treorchy | 925 | −29 kWh |
| Baglan | 1,027 | +73 kWh |
| Neath | 996 | +42 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.
