Against Great Britain as a whole: Greasby makes 990 kWh per kWp a year, and the mean of our 85 county PVGIS estimates (our GB average) is 925, so Greasby is 7% above it.
How Greasby compares
Small towns rarely get published solar figures, so here are the numbers for Greasby. It is one of 45 Cheshire towns we track, and it ranks 2nd of 45 for solar yield, a town of 9,179 people in the House of Commons Library settlement data. PVGIS gives its roofs 990 kWh per kWp a year, 2.71 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £890 of year one benefit, £247 of it from your own generation and £643 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Greasby'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 Wirral; nationally, the House of Commons Library classes Greasby 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.

SP Energy Networks and your Greasby connection
SP Energy Networks owns and runs the local electricity network in Greasby, as part of its North Wales, Merseyside and Cheshire licence area.
What decides the paperwork is the inverter and battery output, not the number of panels. Up to 3.68kW per phase, a system follows G98: SP Energy Networks is notified within 28 days of commissioning and nothing has to be approved first.
Above that, G99 means applying before the work is booked. 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.

Adding a heat pump or an EV charger in Greasby
A heat pump in Greasby
In December, the darkest month here, 12 panels in Greasby make about 190 kWh. That is when a heat pump runs hardest, so its running cost in Greasby 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 Greasby
Greasby's May output, about 830 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.
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 Greasby
How much energy would 12 solar panels make in Greasby?
Greasby averages 2.71 peak sun hours a day, which PVGIS turns into 990 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,300 kWh, 69% of it between April and September.
Is solar more expensive in Greasby?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Greasby, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,300 kWh a year here, which is what drives payback.
Who is the network operator in Greasby, 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 could I earn from exporting in Greasby?
On the 12p export scenario, a 12-panel system in Greasby sends about 5,360 kWh a year to the grid, worth around £643. The export rates table compares what each supplier pays.
How does solar perform in Greasby in the winter months?
December is the weakest month in Greasby: about 190 kWh from 12 panels, against 830 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Greasby 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 Greasby |
|---|---|---|
| Greasby | 990 | this town |
| West Kirby | 991 | +1 kWh |
| Birkenhead | 974 | −16 kWh |
| Heswall | 985 | −5 kWh |
| Wallasey | 982 | −8 kWh |
| Bebington | 959 | −31 kWh |
| Neston | 969 | −21 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.
