How Horwich compares
Small towns rarely get published solar figures, so here are the numbers for Horwich. It is one of 109 Lancashire towns we track, and it ranks 48th of 109 for solar yield, a town of 21,774 people in the House of Commons Library settlement data. PVGIS gives its roofs 920 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 £837 of year one benefit, £247 of it from your own generation and £590 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Horwich'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.
Horwich sits within Bolton, 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.

Generation is modelled from PVGIS satellite data for Horwich's own coordinates (53.59186, -2.54041), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate; the methodology is on our help page.
Connecting solar to the Horwich network
On NESO's licence-area map, Horwich 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.
Anything bigger is a G99 case and is applied for 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.

Heat pumps and EV charging in Horwich
A heat pump in Horwich
Solar and a heat pump pull in opposite directions through the year: Horwich's roofs make 910 kWh from November to February on a 12-panel system, and 2,850 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Horwich
From April to September, 70% of a Horwich roof's yearly output arrives, peaking at about 770 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.
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.

Solar in Horwich: your questions answered
What could a roof in Horwich generate?
PVGIS puts a roof in Horwich at 920 kWh per kWp a year, 2.52 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 5,850 kWh a year, most of it between April and September.
How much are solar panels in Horwich?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Horwich before a battery. What Horwich changes is the return, about 5,850 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Horwich?
Usually not in advance. Electricity North West, the network operator for Horwich, 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 Horwich?
With typical use and no battery, a 12-panel system in Horwich exports about 4,915 kWh a year. At 12p per kWh that is roughly £590; 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 Horwich?
Yes, at a lower level. PVGIS gives Horwich 27.1 kWh per kWp in December and 28.7 in January, so a 12-panel system makes about 170 kWh and 180 kWh in those months, against 770 kWh in May. Winter output mostly covers daytime use rather than exporting.
