How Pembroke compares
Small towns rarely get published solar figures, so here are the numbers for Pembroke. It is one of 4 Pembrokeshire towns we track, and it ranks 2nd of 4 for solar yield, a town of 7,854 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,086 kWh per kWp a year, 2.97 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £963 of year one benefit, £247 of it from your own generation and £716 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 Pembroke's own yield.
Any planning application in Pembroke sits with Pembrokeshire, 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.

The network operator for Pembroke
The distribution network operator (DNO) for Pembroke is National Grid Electricity Distribution (NGED), which runs the South Wales licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means NGED is notified within 28 days of switch-on rather than asked beforehand.
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 Pembroke
A heat pump in Pembroke
In December, the darkest month here, 12 panels in Pembroke make about 200 kWh. That is when a heat pump runs hardest, so its running cost in Pembroke comes down to the tariff and the flow temperature rather 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 Pembroke
Summer is where a car earns its place. In May, 12 panels in Pembroke make about 890 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.
If you rent, or own a flat, and have private off-street parking, the government chargepoint grant covers 75% of the cost, capped at £500 a socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above prices a 7.4kW smart charger from £1,100 installed.

Common questions about solar in Pembroke
How much electricity do solar panels make in Pembroke?
About 6,910 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Pembroke: 1,086 kWh per kWp, or 2.97 peak sun hours a day on average. May is the strongest month, at about 890 kWh.
What does a typical solar system cost in Pembroke?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Pembroke, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,910 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Pembroke, and what does it need from me?
National Grid Electricity Distribution (NGED) covers Pembroke. 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 Pembroke?
Around £716 a year at 12p per kWh, for the roughly 5,970 kWh a 12-panel system in Pembroke 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 Pembroke get in December?
December is the low point: about 200 kWh from a 12-panel system in Pembroke, on PVGIS data, rising to 890 kWh in May. From November to February the same system makes about 1,050 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Pembroke compares with its neighbours
How the towns nearest Pembroke compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Pembroke |

| Pembroke | 1,086 | this town |
| Pembroke Dock | 1,080 | −6 kWh |
| Milford Haven | 1,095 | +9 kWh |
| Haverfordwest | 1,023 | −63 kWh |
| Carmarthen | 980 | −106 kWh |
| Llanelli | 1,064 | −22 kWh |
| Gorseinon | 1,040 | −46 kWh |
PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.
