How Irlam compares
Small towns rarely get published solar figures, so here are the numbers for Irlam. It is one of 109 Lancashire towns we track, and it ranks 47th of 109 for solar yield, a town of 19,785 people in the House of Commons Library settlement data. PVGIS gives its roofs 921 kWh per kWp a year, 2.52 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £838 of year one benefit, £247 of it from your own generation and £591 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 Irlam's own yield.
Any planning application in Irlam sits with Salford, and its official House of Commons Library settlement class is 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.

Electricity North West and your Irlam connection
Irlam sits in Electricity North West's North West England licence area, so Electricity North West is the network operator (DNO) any solar panels or battery here are registered with.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to Electricity North West within 28 days of commissioning, with no prior approval.
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 Electricity North West as it does every network operator.

Beyond the panels: heating and car charging in Irlam
A heat pump in Irlam
In December, the darkest month here, 12 panels in Irlam make about 180 kWh. That is when a heat pump runs hardest, so its running cost in Irlam comes down to the tariff and the flow temperature rather than the roof.
Grant support in England comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Irlam
Irlam's May output, about 760 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.
If you rent, or own a flat, and have private off-street parking, the government chargepoint grant covers 75% of the cost, capped at £500 a socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above prices a 7.4kW smart charger from £1,100 installed.

Common questions about solar in Irlam
How much electricity do solar panels make in Irlam?
About 5,860 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Irlam: 921 kWh per kWp, or 2.52 peak sun hours a day on average. May is the strongest month, at about 760 kWh.
Is solar more expensive in Irlam?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Irlam, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 5,860 kWh a year here, which is what drives payback.
Which DNO covers Irlam, and what does it need from me?
Electricity North West covers Irlam. A home system of up to 3.68kW per phase is notified to Electricity North West within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. 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 Electricity North West as it does every network operator.
What could I earn from exporting in Irlam?
On the 12p export scenario, a 12-panel system in Irlam sends about 4,921 kWh a year to the grid, worth around £591. The export rates table compares what each supplier pays.
How much solar does Irlam get in December?
December is the low point: about 180 kWh from a 12-panel system in Irlam, on PVGIS data, rising to 760 kWh in May. From November to February the same system makes about 920 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Irlam compares with its neighbours
How the towns nearest Irlam compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Irlam |
|---|---|---|
| Irlam | 921 | this town |
| Partington | 921 | level |
| Urmston | 913 | −8 kWh |
| Eccles | 913 | −8 kWh |
| Sale | 913 | −8 kWh |
| Lymm | 930 | +9 kWh |
| Altrincham | 922 | +1 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.
