How Baglan compares
Small towns rarely get published solar figures, so here are the numbers for Baglan. It is one of 32 Glamorgan towns we track, and it ranks 12th of 32 for solar yield, a town of 10,681 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,027 kWh per kWp a year, 2.81 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £918 of year one benefit, £247 of it from your own generation and £671 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 Baglan's own yield.
Any planning application in Baglan sits with Neath Port Talbot, and its official House of Commons Library settlement class is 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 Baglan's own coordinates (51.62739, -3.81418), 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.
The network operator for Baglan
The distribution network operator (DNO) for Baglan is National Grid Electricity Distribution (NGED), which runs the South Wales licence area.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, NGED only has to be told within 28 days after the system is commissioned.
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.

Beyond the panels: heating and car charging in Baglan
A heat pump in Baglan
Heating demand peaks when solar is weakest. In Baglan, a 12-panel system makes about 200 kWh in December and 210 kWh in January, a fraction of its 840 kWh in May, which is why a heat pump here is costed on its tariff first.
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 Baglan
Summer is where a car earns its place. In May, 12 panels in Baglan make about 840 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.
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.

Common questions about solar in Baglan
How much energy would 12 solar panels make in Baglan?
Baglan averages 2.81 peak sun hours a day, which PVGIS turns into 1,027 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,530 kWh, 70% of it between April and September.
What does a typical solar system cost in Baglan?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Baglan, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,530 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Baglan, and do I need a G99 application?
The operator is National Grid Electricity Distribution (NGED). Most home systems use the G98 route, a notification within 28 days of switch-on for up to 3.68kW per phase, so nothing waits on the network. Above that, G99 applies and has to be granted first. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. Your design call checks which route yours needs.
What happens to the solar I do not use in Baglan?
Around £671 a year at 12p per kWh, for the roughly 5,595 kWh a 12-panel system in Baglan exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How does solar perform in Baglan in the winter months?
December is the weakest month in Baglan: about 200 kWh from 12 panels, against 840 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Baglan 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 Baglan |
|---|---|---|
| Baglan | 1,027 | this town |
| Neath | 996 | −31 kWh |
| Port Talbot | 1,026 | −1 kWh |
| Clydach | 981 | −46 kWh |
| Swansea | 1,023 | −4 kWh |
| Maesteg | 954 | −73 kWh |
| North Cornelly and Kenfig Hill | 1,059 | +32 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.
