Solar panels for warehouses in Carlisle
Sheds around Carlisle tend to have more roof than the business has any other use for. What decides a scheme here is the state of the covering and the load path, which is why the survey starts on the roof rather than in a spreadsheet.
806 kWh per kWp a year at this latitude, so a 500 kWp array models at about 403,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Distribution centre solar across Cumbria
What a roof in Carlisle actually generates
Modelled irradiation at this latitude is 1027 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 806 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 9 percent below the mean across the towns we cover, so the case here leans harder on how much you use on site rather than on raw generation.
Distribution stock around Carlisle clusters on M6 J42, M6 J44 and A69, which is where the large single-let roofs are.
We survey across the CA postcode area, starting from CA2.
Carlisle is the planning authority for most sites here, and the built-up area holds a population of about 77,730, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Carlisle ranks 4 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 500 kWp array that is about 50,000 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 Carlisle
- What would a 500 kWp array produce in Carlisle?
- Yes, and the number matters more than the sunshine. At 806 kWh per kWp a year, a 500 kWp array on a Carlisle roof models at around 403,000 kWh. What changes the answer is how much of that you use on site rather than export. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Which network operator handles the connection in Carlisle?
- Applications go to Electricity North West, who run the network across Cumbria. They decide the export limit, and we handle the G99 paperwork alongside the array design.
- What does Carlisle require for rooftop solar?
- Roof-mounted panels on a commercial building usually fall under permitted development, subject to the limits on projection above the roof plane and to the building not being listed or in a conservation area. We confirm the position with Carlisle before the design is finalised.
