How New Mills compares
Small towns rarely get published solar figures, so here are the numbers for New Mills. It is one of 28 Derbyshire towns we track, and it ranks 27th of 28 for solar yield, a town of 9,137 people in the House of Commons Library settlement data. PVGIS gives its roofs 870 kWh per kWp a year, 2.38 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £799 of year one benefit, £247 of it from your own generation and £552 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on New Mills' 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.
New Mills sits within High Peak, its local planning authority, and the House of Commons Library classes it 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.

Connecting solar to the New Mills network
On NESO's licence-area map, New Mills is in North West England, which Electricity North West operates. That makes Electricity North West the network operator for any system fitted here.
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.
A bigger inverter or battery output needs a G99 application in advance. 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.

Heat pumps and EV charging in New Mills
A heat pump in New Mills
Solar and a heat pump pull in opposite directions through the year: New Mills' roofs make 770 kWh from November to February on a 12-panel system, and 2,750 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 New Mills
From April to September, 71% of a New Mills roof's yearly output arrives, peaking at about 730 kWh in May on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
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).

New Mills solar questions
What could a roof in New Mills generate?
PVGIS puts a roof in New Mills at 870 kWh per kWp a year, 2.38 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 5,530 kWh a year, most of it between April and September.
How much are solar panels in New Mills?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in New Mills before a battery. What New Mills changes is the return, about 5,530 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in New Mills?
Usually not in advance. Electricity North West, the network operator for New Mills, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval 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 Electricity North West as it does every network operator. "See our DNO explainer.
How much can I earn from exporting solar in New Mills?
With typical use and no battery, a 12-panel system in New Mills exports about 4,597 kWh a year. At 12p per kWh that is roughly £552; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in New Mills?
Yes, at a lower level. PVGIS gives New Mills 23.3 kWh per kWp in December and 22.3 in January, so a 12-panel system makes about 150 kWh and 140 kWh in those months, against 730 kWh in May. Winter output mostly covers daytime use rather than exporting.
