Commercial building solar panels in Burnley
An office or store in Burnley buys most of its electricity between eight in the morning and six at night, which is when a roof array generates. We check the covering and the lease together, because a roof with eight years of membrane left and a tenant with a break in three changes the answer.
774 kWh per kWp a year at this latitude, so a 210 kWp array models at about 163,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Solar for offices and retail across Lancashire
How much sun a Burnley roof gets
Modelled irradiation here is 987 kWh per square metre a year on a low-tilt array, which works out at 774 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 13 percent below the mean across the towns we cover, so the case here rests more on daytime consumption than on raw generation.
The rating list for Burnley
The Valuation Office Agency's rating list puts 770 office and 1,190 retail properties in Burnley, covering about 90,000 and 190,000 square metres of floorspace respectively. By office stock the district sits below the median of the 318 districts in England and Wales; by retail stock it sits above the median of the 318 districts in England and Wales.
The big roofs are in the 40 large-format retail units, superstores and retail warehouses in the district, about 44,000 square metres of floorspace under largely single storey roofs.
The same list carries 110 hotel, leisure and assembly properties in the district. Leisure centres and hotels run seven days a week, which puts weekend generation to use that an office would export.

The built-up area holds about 78,255 people, so the stock here runs to high street premises, a supermarket or two and the odd hotel (ONS Census 2021 built-up areas).
We arrange surveys across the BB postcode area, starting from BB11.
Burnley ranks 8 of 8 towns we cover in Lancashire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 774 to 888, a spread of 114 kWh per kWp. On a 210 kWp commercial roof that is about 23,940 kWh a year between the strongest and weakest town in the county.
Grid connection through Electricity North West
Connections around Burnley are handled by Electricity North West, which sets the export limit for the site. Above 3.68 kW per phase the connection runs under G99, so the export limit is agreed in advance rather than assumed. Where the local network is constrained, an export-limited connection usually still makes the scheme work, because a commercial building uses most of what the roof makes during the working day.
Across Lancashire the planning database records 161 solar schemes totalling 521 MW, of which 25 are operational (REPD Q1 2026).

Questions about solar in Burnley
- How much would solar on a commercial building in Burnley generate?
- The model gives 774 kWh for every kWp installed here, so 210 kWp is about 163,000 kWh a year before shading losses. Allow roughly 1,390 m² of roof for it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Do we need planning permission for solar on a commercial building in Burnley?
- Usually not a full application. In England, panels on the roof of a non-domestic building are permitted development under Class J of Part 14 of the General Permitted Development Order, with no capacity cap since December 2023. Above 50 kW, which covers most commercial arrays, you must first apply to Burnley for a determination on prior approval of the design and appearance, in particular glare on neighbouring land. On a flat roof panels may stand no more than 1 metre above the roof and must sit at least 1 metre from its edge, and listed buildings and scheduled monuments are excluded. See our planning permission guide for the detail.
- Does solar help a Burnley landlord meet MEES?
- It can. A non-domestic EPC is an asset rating, and on-site generation counts in the calculation, so an array usually lifts the score. Let property in England and Wales must be EPC E or better today. The government's interim response of 18 June 2026 proposes EPC B, where cost effective, from 2031 for let buildings over 1,000 m², and drops the EPC C step once planned for 2027. How far solar moves a particular building depends on its fabric and services, which is why the EPC assessor models it before anything is fitted.
- Which network operator handles the connection in Burnley?
- Capacity varies street by street and only Electricity North West can answer it for your connection. We ask early, because an export-limited offer changes the design rather than ending the scheme, and most commercial buildings use most of what they generate anyway.
