Solar panels for warehouses in Macclesfield
What makes a Macclesfield scheme work is rarely the panels. It is the condition of the roof underneath them. The survey measures the roof, not the postcode: cladding profile, purlin centres, remaining sheet life and the load the frame can take.
790 kWh per kWp a year at this latitude, so a 500 kWp array models at about 395,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Macclesfield actually generates
Modelled irradiation at this latitude is 1010 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 790 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 11 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.
Surveys run across SK postcodes, SK11 outward.
Cheshire East is the planning authority for most sites here, and the built-up area holds a population of about 54,345, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Macclesfield ranks 8 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 is the network operator here, and their answer on export capacity shapes the design. Any commercial array above 3.68 kW per phase connects under G99 rather than G98, and the application fixes what you are allowed to push back onto the network. If the local network is tight, limiting export rarely breaks the case here: most of the generation is consumed on site while the building is working.
Across Cheshire the planning database records 157 solar schemes totalling 582 MW, of which 13 are operational (REPD Q1 2026).

Questions about solar in Macclesfield
- How much does a warehouse roof in Macclesfield generate?
- The model gives 790 kWh for every kWp installed here, so 500 kWp comes out at about 395,000 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 Macclesfield 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 Macclesfield 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.
