How Pembroke Dock compares
Small towns rarely get published solar figures, so here are the numbers for Pembroke Dock. It is one of 4 Pembrokeshire towns we track, and it ranks 3rd of 4 for solar yield, a town of 9,782 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,080 kWh per kWp a year, 2.96 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £959 of year one benefit, £247 of it from your own generation and £712 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Pembroke Dock'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.
Planning applications here go through Pembrokeshire; nationally, the House of Commons Library classes Pembroke Dock 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.

NGED and your Pembroke Dock connection
National Grid Electricity Distribution (NGED) owns and runs the local electricity network in Pembroke Dock, as part of its 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.
Above that, G99 means applying before the work is booked. 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 Pembroke Dock
A heat pump in Pembroke Dock
Heating demand peaks when solar is weakest. In Pembroke Dock, a 12-panel system makes about 180 kWh in December and 220 kWh in January, a fraction of its 890 kWh in May, which is why a heat pump here is costed on its tariff first.
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 Pembroke Dock
Pembroke Dock's May output, about 890 kWh from 12 panels, is several times the 70 kWh or so a typical home uses in daylight that month on our calculator's settings. Daytime charging turns that surplus into miles.
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).

Is solar more expensive in Pembroke Dock?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Pembroke Dock, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,870 kWh a year here, which is what drives payback.
Which DNO covers Pembroke Dock, and what does it need from me?
National Grid Electricity Distribution (NGED) covers Pembroke Dock. 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 could I earn from exporting in Pembroke Dock?
On the 12p export scenario, a 12-panel system in Pembroke Dock sends about 5,932 kWh a year to the grid, worth around £712. The export rates table compares what each supplier pays.
How much solar does Pembroke Dock get in December?
December is the low point: about 180 kWh from a 12-panel system in Pembroke Dock, on PVGIS data, rising to 890 kWh in May. From November to February the same system makes about 1,020 kWh in total, which is why a battery charged off-peak does more of the work in winter.
