How Altrincham compares
Among the places we publish figures for, Altrincham is one of 45 Cheshire towns we track, and it ranks 22nd of 45 for solar yield. It is a medium town in the House of Commons Library classification, with 50,024 residents, and its roofs see 2.52 peak sun hours a day across the year. That drives the standard 12 panel model to 5,864 kWh of generation, of which around 4,927 kWh is exported at 12p for £591 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
These are starting numbers, not a quote. The calculator below opens on Altrincham'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 Trafford; nationally, the House of Commons Library classes Altrincham as a medium 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.

The network operator for Altrincham
On NESO's licence-area map, Altrincham is in North West England, which Electricity North West operates. That makes Electricity North West 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 Electricity North West within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
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.

Adding a heat pump or an EV charger in Altrincham
A heat pump in Altrincham
Heating demand peaks when solar is weakest. In Altrincham, a 12-panel system makes about 180 kWh in December and 180 kWh in January, a fraction of its 750 kWh in May, which is why a heat pump here is costed on its tariff first.
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 Altrincham
Altrincham's May output, about 750 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.
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 Altrincham
How much electricity do solar panels make in Altrincham?
About 5,860 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Altrincham: 922 kWh per kWp, or 2.52 peak sun hours a day on average. May is the strongest month, at about 750 kWh.
Is solar more expensive in Altrincham?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Altrincham, 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 Altrincham, and what does it need from me?
Electricity North West covers Altrincham. 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 Altrincham?
On the 12p export scenario, a 12-panel system in Altrincham sends about 4,927 kWh a year to the grid, worth around £591. The export rates table compares what each supplier pays.
How much solar does Altrincham get in December?
December is the low point: about 180 kWh from a 12-panel system in Altrincham, on PVGIS data, rising to 750 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 Altrincham compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Altrincham.
| Town | kWh per kWp a year | vs Altrincham |
|---|---|---|
| Altrincham | 922 | this town |
| Sale | 913 | −9 kWh |
| Hale | 921 | −1 kWh |
| Wythenshawe | 912 | −10 kWh |
| Partington | 921 | −1 kWh |
| Stretford | 908 | −14 kWh |
| Urmston | 913 | −9 kWh |
PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.
