Solar panels for warehouses in Wilmslow
The economics of a Wilmslow rooftop array turn on how much of the generation the occupier uses on site. Each survey records the cladding profile, the usable area once rooflights and plant are removed, and the export limit worth applying for.
801 kWh per kWp a year at this latitude, so a 500 kWp array models at about 401,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Warehouse rooftop solar across Cheshire
What a roof in Wilmslow actually generates
Modelled irradiation at this latitude is 1026 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 801 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 leans harder on how much you use on site rather than on raw generation.
Most of the units we look at here sit in the SK postcode area.
Cheshire East is the planning authority for most sites here, and the built-up area holds a population of about 25,725, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Wilmslow ranks 7 of 8 towns we cover in Cheshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 790 to 840, a spread of 50 kWh per kWp. On a 500 kWp array that is about 25,000 kWh a year between the strongest and weakest town in the county.

Grid connection through SP Energy Networks / Electricity North West
SP Energy Networks / Electricity North West operates the distribution network across Cheshire, 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 Cheshire the planning database records 157 solar schemes totalling 582 MW, of which 13 are operational (REPD Q1 2026).

Questions about solar in Wilmslow
- How much does a warehouse roof in Wilmslow generate?
- The model gives 801 kWh for every kWp installed here, so 500 kWp comes out at about 401,000 kWh a year before any shading losses. You need roughly 1,485 sqm of clear roof to fit it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Does the grid around Wilmslow have capacity?
- SP Energy Networks / Electricity North West is the distribution network operator for Cheshire. Anything above 3.68 kW per phase connects under G99, and the application sets the export limit. We submit it as part of the design.
- Is planning permission needed for panels on a Wilmslow unit?
- Usually permitted development covers it. We still put the question to Cheshire East before design sign-off, and we tell you early if a full application is needed rather than discovering it late.
