Commercial building solar panels in Kendal
A flat commercial roof in Kendal is usually the largest surface a building owns and the one nobody is asked to manage. 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.
793 kWh per kWp a year at this latitude, so a 210 kWp array models at about 167,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Solar PV for commercial property across Cumbria
What a flat roof in Kendal generates
Modelled irradiation here is 1,014 kWh per square metre a year on a low-tilt array, which works out at 793 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 10 percent below the mean across the towns we cover, so the case here rests more on daytime consumption than on raw generation.
Commercial stock in Westmorland and Furness
Westmorland and Furness has 1,480 office premises and 2,710 shops and other retail premises on the non-domestic rating list, according to the Valuation Office Agency. By office stock the district sits in the top quarter of the 318 districts in England and Wales; by retail stock it sits in the top quarter of the 318 districts in England and Wales.
The big roofs are in the 70 large-format retail units, superstores and retail warehouses in the district, about 182,000 square metres of floorspace under largely single storey roofs.
The same list carries 870 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 28,940 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 LA postcode area, starting from LA9.
Kendal ranks 6 of 6 towns we cover in Cumbria on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 793 to 893, a spread of 100 kWh per kWp. On a 210 kWp commercial roof that is about 21,000 kWh a year between the strongest and weakest town in the county.
Grid connection through Electricity North West
Electricity North West operates the distribution network across Cumbria, so the export application goes to them. Anything larger than 3.68 kW per phase falls under G99, which means an application before commissioning rather than a notification afterwards. A constrained network is not the end of a scheme. Capping export costs little when the building already absorbs most of what the roof produces.
Across Cumbria the planning database records 86 solar schemes totalling 574 MW, of which 17 are operational (REPD Q1 2026).

Questions about solar in Kendal
- What would a 210 kWp array produce in Kendal?
- Yes. At 793 kWh per kWp a year, a 210 kWp array on a Kendal roof models at around 167,000 kWh. What changes the answer is how much of that the building uses during opening hours rather than exports. 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 Westmorland and Furness?
- 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 Westmorland and Furness 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 Kendal 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 Kendal?
- 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.
