How Mold compares
Small towns rarely get published solar figures, so here are the numbers for Mold. It is one of 8 Flintshire towns we track, and it ranks 7th of 8 for solar yield, a town of 10,039 people in the House of Commons Library settlement data. PVGIS gives its roofs 944 kWh per kWp a year, 2.59 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £855 of year one benefit, £247 of it from your own generation and £608 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 Mold's own yield.
Mold sits within Flintshire, its local planning authority, and the House of Commons Library classes it 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.

Connecting solar to the Mold network
The distribution network operator (DNO) for Mold is SP Energy Networks, which runs the North Wales, Merseyside and Cheshire licence area.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, SP Energy Networks only has to be told within 28 days after the system is commissioned.
Anything bigger is a G99 case and is applied for first. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds SP Energy Networks as it does every network operator.

Beyond the panels: heating and car charging in Mold
A heat pump in Mold
Solar and a heat pump pull in opposite directions through the year: Mold's roofs make 960 kWh from November to February on a 12-panel system, and 2,910 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Mold
From April to September, 69% of a Mold roof's yearly output arrives, peaking at about 770 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.
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).

Solar in Mold: your questions answered
What could a roof in Mold generate?
PVGIS puts a roof in Mold at 944 kWh per kWp a year, 2.59 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,000 kWh a year, most of it between April and September.
What would 12 solar panels cost in Mold?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Mold differs is output: about 6,000 kWh a year from that system.
Do I need permission from the DNO for solar in Mold?
Usually not in advance. SP Energy Networks, the network operator for Mold, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval first. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds SP Energy Networks as it does every network operator. "See our DNO explainer.
How much would export pay on a system in Mold?
It is exported. With typical use and no battery, about 5,067 kWh of the 6,000 kWh a 12-panel system makes in Mold goes to the grid, around £608 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Do solar panels work in winter in Mold?
Yes, at a lower level. PVGIS gives Mold 30.6 kWh per kWp in December and 31.4 in January, so a 12-panel system makes about 190 kWh and 200 kWh in those months, against 770 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Mold compares with its neighbours
How the towns nearest Mold compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Mold |
|---|---|---|
| Mold | 944 | this town |
| Buckley | 958 | +14 kWh |
| Connah's Quay | 967 | +23 kWh |
| Hawarden | 962 | +18 kWh |
| Flint | 962 | +18 kWh |
| Brynteg | 955 | +11 kWh |
| Gwersyllt | 956 | +12 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.
