How Hayle compares
Small towns rarely get published solar figures, so here are the numbers for Hayle. It is one of 14 Cornwall towns we track, and it ranks 2nd of 14 for solar yield, a town of 9,461 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,102 kWh per kWp a year, 3.02 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £976 of year one benefit, £247 of it from your own generation and £729 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Hayle'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 Cornwall; nationally, the House of Commons Library classes Hayle 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 Hayle's own coordinates (50.18853, -5.41168), 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.
NGED and your Hayle connection
On NESO's licence-area map, Hayle is in South West England, which National Grid Electricity Distribution (NGED) operates. That makes NGED 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 NGED within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
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.

Adding a heat pump or an EV charger in Hayle
A heat pump in Hayle
Heating demand peaks when solar is weakest. In Hayle, a 12-panel system makes about 220 kWh in December and 260 kWh in January, a fraction of its 860 kWh in May, which is why a heat pump here is costed on its tariff first.
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 Hayle
Summer is where a car earns its place. In May, 12 panels in Hayle make about 860 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.
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).

Common questions about solar in Hayle
How much energy would 12 solar panels make in Hayle?
Hayle averages 3.02 peak sun hours a day, which PVGIS turns into 1,102 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 7,010 kWh, 69% of it between April and September.
What does a typical solar system cost in Hayle?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Hayle, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 7,010 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Hayle, and do I need a G99 application?
The operator is National Grid Electricity Distribution (NGED). 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. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. Your design call checks which route yours needs.
What happens to the solar I do not use in Hayle?
Around £729 a year at 12p per kWh, for the roughly 6,072 kWh a 12-panel system in Hayle 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 Hayle in the winter months?
December is the weakest month in Hayle: about 220 kWh from 12 panels, against 860 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Hayle compares with its neighbours
How the towns nearest Hayle compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Hayle |
|---|---|---|
| Hayle | 1,102 | this town |
| Camborne | 1,026 | −76 kWh |
| Penzance | 1,099 | −3 kWh |
| Helston | 1,110 | +8 kWh |
| Redruth | 1,038 | −64 kWh |
| Penryn | 1,062 | −40 kWh |
| Falmouth | 1,056 | −46 kWh |
Each row is a PVGIS v5.2 run at that town's centre with the same settings. Treat gaps of a few kWh as noise and gaps over about 30 kWh per kWp as real differences in sunshine.
