How Flint compares
Small towns rarely get published solar figures, so here are the numbers for Flint. It is one of 8 Flintshire towns we track, and it ranks joint 3rd of 8 for solar yield, a town of 13,075 people in the House of Commons Library settlement data. PVGIS gives its roofs 962 kWh per kWp a year, 2.63 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.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Flint's own yield, and prices a 12 panel system at £6,360 installed before any battery. Your free design call reworks every number for your actual roof, its shading and your usage.
Planning applications here go through Flintshire; nationally, the House of Commons Library classes Flint 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 Flint's own coordinates (53.24503, -3.13497), 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 Flint
Flint sits in SP Energy Networks' North Wales, Merseyside and Cheshire licence area, so SP Energy Networks is the network operator (DNO) any solar panels or battery here are registered with.
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.
Larger systems go through G99 instead, applied for before installation. On timing: 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.

Heat pumps and EV charging in Flint
A heat pump in Flint
In December, the darkest month here, 12 panels in Flint make about 200 kWh. That is when a heat pump runs hardest, so its running cost in Flint comes down to the tariff and the flow temperature rather than the roof.
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 Flint
Summer is where a car earns its place. In May, 12 panels in Flint make about 790 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.

Flint solar questions
How much energy would 12 solar panels make in Flint?
Flint averages 2.63 peak sun hours a day, which PVGIS turns into 962 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,120 kWh, 69% of it between April and September.
What does a typical solar system cost in Flint?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Flint, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,120 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Flint, and do I need a G99 application?
The operator is SP Energy Networks. 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. 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. Your design call checks which route yours needs.
What happens to the solar I do not use in Flint?
Around £622 a year at 12p per kWh, for the roughly 5,182 kWh a 12-panel system in Flint 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 Flint in the winter months?
December is the weakest month in Flint: about 200 kWh from 12 panels, against 790 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Flint compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Flint.
| Town | kWh per kWp a year | vs Flint |
|---|---|---|
| Flint | 962 | this town |
| Connah's Quay | 967 | +5 kWh |
| Holywell | 952 | −10 kWh |
| Neston | 969 | +7 kWh |
| Mold | 944 | −18 kWh |
| Buckley | 958 | −4 kWh |
| Hawarden | 962 | level |
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.
