How Lymm compares
Small towns rarely get published solar figures, so here are the numbers for Lymm. It is one of 45 Cheshire towns we track, and it ranks joint 19th of 45 for solar yield, a town of 12,195 people in the House of Commons Library settlement data. PVGIS gives its roofs 930 kWh per kWp a year, 2.55 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £844 of year one benefit, £247 of it from your own generation and £597 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Lymm'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 Warrington; nationally, the House of Commons Library classes Lymm 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 Lymm connection
Lymm is served by SP Energy Networks: the town's centre falls inside its North Wales, Merseyside and Cheshire licence area on NESO's boundary map.
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.
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 Lymm
A heat pump in Lymm
Heating demand peaks when solar is weakest. In Lymm, a 12-panel system makes about 180 kWh in December and 180 kWh in January, a fraction of its 760 kWh in May, which is why a heat pump here is costed on its tariff first.
In England, the Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump and £2,500 towards an air-to-air one, with £1,500 more until March 2027 for homes heated by oil or LPG with no mains gas (gov.uk, checked 28 September 2026).
Charging an EV in Lymm
Summer is where a car earns its place. In May, 12 panels in Lymm make about 760 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.

Lymm solar questions
How much electricity do solar panels make in Lymm?
About 5,910 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Lymm: 930 kWh per kWp, or 2.55 peak sun hours a day on average. May is the strongest month, at about 760 kWh.
What does a typical solar system cost in Lymm?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Lymm, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 5,910 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Lymm, and what does it need from me?
SP Energy Networks covers Lymm. A home system of up to 3.68kW per phase is notified to SP Energy Networks 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 SP Energy Networks as it does every network operator.
What happens to the solar I do not use in Lymm?
Around £597 a year at 12p per kWh, for the roughly 4,978 kWh a 12-panel system in Lymm exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Lymm get in December?
December is the low point: about 180 kWh from a 12-panel system in Lymm, on PVGIS data, rising to 760 kWh in May. From November to February the same system makes about 930 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Lymm compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Lymm.
| Town | kWh per kWp a year | vs Lymm |
|---|---|---|
| Lymm | 930 | this town |
| Partington | 921 | −9 kWh |
| Irlam | 921 | −9 kWh |
| Warrington | 936 | +6 kWh |
| Altrincham | 922 | −8 kWh |
| Urmston | 913 | −17 kWh |
| Sale | 913 | −17 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.
