How Great Harwood compares
Small towns rarely get published solar figures, so here are the numbers for Great Harwood. It is one of 109 Lancashire towns we track, and it ranks 90th of 109 for solar yield, a town of 11,468 people in the House of Commons Library settlement data. PVGIS gives its roofs 872 kWh per kWp a year, 2.39 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £800 of year one benefit, £247 of it from your own generation and £553 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 Great Harwood's own yield.
Great Harwood sits within Hyndburn, 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 Great Harwood network
Great Harwood is served by Electricity North West: the town's centre falls inside its North West England licence area on NESO's boundary map.
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.
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.

Beyond the panels: heating and car charging in Great Harwood
A heat pump in Great Harwood
Solar and a heat pump pull in opposite directions through the year: Great Harwood's roofs make 810 kWh from November to February on a 12-panel system, and 2,740 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 Great Harwood
A 12-panel roof in Great Harwood makes about 740 kWh in May. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
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).

Solar in Great Harwood: your questions answered
What could a roof in Great Harwood generate?
PVGIS puts a roof in Great Harwood at 872 kWh per kWp a year, 2.39 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 5,550 kWh a year, most of it between April and September.
How much are solar panels in Great Harwood?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Great Harwood before a battery. What Great Harwood changes is the return, about 5,550 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Great Harwood?
Usually not in advance. Electricity North West, the network operator for Great Harwood, 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 Great Harwood?
With typical use and no battery, a 12-panel system in Great Harwood exports about 4,609 kWh a year. At 12p per kWh that is roughly £553; 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 Great Harwood?
Yes, at a lower level. PVGIS gives Great Harwood 22.7 kWh per kWp in December and 24.4 in January, so a 12-panel system makes about 140 kWh and 160 kWh in those months, against 740 kWh in May. Winter output mostly covers daytime use rather than exporting.
