What the figures show
Capacity in Chorley has grown by 103% since the end of 2020, faster than the UK as a whole (69%). In 2025 alone it rose from 14.8 MW to 16.9 MW.
There are 92.6 installations for every 1,000 households, above the North West median of 52.1 and above the UK median of 67.0. That is 90th of 361 council areas, and 3rd of 35 in North West.
At 3.6 kW on average, most installations here are home-sized, so business roofs make up a small share of what is installed so far.
What a business roof in Chorley could generate
Modelled with PVGIS for the centre of Chorley, a south-facing roof at 30 degrees produces about 880 kWh per kWp a year. That is 318th of 361 council areas; the UK median is 998 kWh.
| Item | Illustrative figure |
|---|---|
| System | 100 kWp, south facing at 30 degrees |
| Installed cost | £900 per kWp, so £90,000 excluding VAT |
| Generation | 880 kWh per kWp, about 88,000 kWh a year |
| Used on site | 70%, so 61,600 kWh at 24p = £14,784 saved |
| Exported | 30%, so 26,400 kWh at 5p = £1,320 earned |
| Total a year | About £16,104 |
| Simple payback | About 5.6 years before tax relief |
Same sums as our commercial solar calculator: illustrative, not a quote. East- or west-facing roofs, shading and how much power you use in daylight all move these figures, and a company paying corporation tax can usually shorten the payback with capital allowances. See the cost guide for price ranges by system size.
Planning and grid connection
Chorley follows the national planning rules for England. Permitted development rights for non-domestic rooftop solar were widened in December 2023, including removal of the old 1 MW limit, but conditions still apply, especially for listed buildings and conservation areas. Ground-mounted arrays and carports usually need an application to the council, or to a national park authority inside a national park. Our planning permission guide sets out the conditions.
Most commercial systems need G99 approval from the local network operator before they are switched on. The operator follows the postcode rather than the council boundary: our North West page covers the operators in the region, and the Energy Networks Association postcode tool confirms yours. See G99 and DNO applications.

Where these figures come from
Installations, capacity, generation and households: Department for Energy Security and Net Zero, Regional Renewable Statistics, renewable electricity by local authority 2014 to 2025 (workbook). They cover all solar PV, homes and businesses, including ground-mounted schemes. Yield: PVGIS 5.3 (European Commission Joint Research Centre), SARAH3 data and 14% system losses, for the council area's centre point (ONS boundaries, December 2024), modelled 4 November 2026. Distances are between centre points.
Frequently asked questions
How much solar is installed in Chorley?
At the end of 2025, Chorley had 4,638 solar PV installations with a combined capacity of 16.9 MW, which generated about 15 GWh in 2025, according to government figures. That covers homes, businesses and ground-mounted schemes.
How much would solar on a business roof in Chorley generate?
About 880 kWh per kWp a year for a south-facing roof at 30 degrees, modelled with PVGIS for the centre of Chorley. A 100 kWp system would make roughly 88,000 kWh a year. Orientation, pitch and shading change this, and a site survey models your own roof.
Can a business in Chorley get a free solar survey?
Yes. Answer six short questions and we match the site with one MCS certified installer, who surveys it on site or by video call. The survey is free and there is no obligation to go ahead. Get a free survey.
