How Hawarden compares
Small towns rarely get published solar figures, so here are the numbers for Hawarden. It is one of 8 Flintshire towns we track, and it ranks joint 3rd of 8 for solar yield, a town of 12,532 people in the House of Commons Library settlement data. PVGIS gives its roofs 962 kWh per kWp a year, 2.64 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £869 of year one benefit, £247 of it from your own generation and £622 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 Hawarden's own yield.
Hawarden 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.

Generation is modelled from PVGIS satellite data for Hawarden's own coordinates (53.19475, -3.02491), 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.
Connecting solar to the Hawarden network
On NESO's licence-area map, Hawarden is in North Wales, Merseyside and Cheshire, which SP Energy Networks operates. That makes SP Energy Networks the network operator for any system fitted here.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to SP Energy Networks within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
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 Hawarden
A heat pump in Hawarden
Solar and a heat pump pull in opposite directions through the year: Hawarden's roofs make 1,010 kWh from November to February on a 12-panel system, and 2,930 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Hawarden
A 12-panel roof in Hawarden makes about 780 kWh in May. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
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 Hawarden
What could a roof in Hawarden generate?
PVGIS puts a roof in Hawarden at 962 kWh per kWp a year, 2.64 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,120 kWh a year, most of it between April and September.
What would 12 solar panels cost in Hawarden?
£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 Hawarden differs is output: about 6,120 kWh a year from that system.
Do I need permission from the DNO for solar in Hawarden?
Usually not in advance. SP Energy Networks, the network operator for Hawarden, 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 Hawarden?
It is exported. With typical use and no battery, about 5,182 kWh of the 6,120 kWh a 12-panel system makes in Hawarden goes to the grid, around £622 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 Hawarden?
Yes, at a lower level. PVGIS gives Hawarden 31.7 kWh per kWp in December and 33.5 in January, so a 12-panel system makes about 200 kWh and 210 kWh in those months, against 780 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Hawarden 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 Hawarden |
|---|---|---|
| Hawarden | 962 | this town |
| Connah's Quay | 967 | +5 kWh |
| Buckley | 958 | −4 kWh |
| Mold | 944 | −18 kWh |
| Chester | 948 | −14 kWh |
| Flint | 962 | level |
| Neston | 969 | +7 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.
