Solar panels for warehouses in Manchester

The economics of a Manchester rooftop array turn on how much of the generation the occupier uses on site. The survey measures the roof, not the postcode: cladding profile, purlin centres, remaining sheet life and the load the frame can take.

What a roof in Manchester 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 788 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.

Distribution stock around Manchester clusters on M60, M62 J11 and M56, which is where the large single-let roofs are.

Most of the units we look at here sit in the M postcode area.

Manchester is the planning authority for most sites here, and the built-up area holds a population of about 470,405, which is large enough to pull in the regional distribution centres that come with the biggest roofs (ONS Census 2021 built-up areas).

May produces 7.0 times what Dec does on the same roof. A 500 kWp array here models at about 394,000 kWh across the year, but it arrives unevenly, which is why we size against your summer daytime load and then look at whether storage is worth adding for the shoulder months.

Manchester ranks 5 of 10 towns we cover in Greater Manchester on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 769 to 828, a spread of 59 kWh per kWp. On a 500 kWp array that is about 29,500 kWh a year between the strongest and weakest town in the county.

From the government's Renewable Energy Planning Database, Q1 2026. These are the schemes on record in this postcode district, which is a fair guide to how the local network has been treating export applications.

Outer Space Studios Solar Panels Ameresco Limited 0.6 MW Roof Operational

Grid connection through Electricity North West

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 Greater Manchester the planning database records 118 solar schemes totalling 110 MW, of which 11 are operational (REPD Q1 2026).

Questions about solar in Manchester

How much does a warehouse roof in Manchester generate?
The model gives 788 kWh for every kWp installed here, so 500 kWp comes out at about 394,000 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 Manchester have capacity?
Electricity North West is the distribution network operator for Greater Manchester. 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 Manchester unit?
Usually permitted development covers it. We still put the question to Manchester before design sign-off, and we tell you early if a full application is needed rather than discovering it late.
Has anyone near M12 already done this?
The planning database records 2 solar schemes in this postcode district, 2 of them roof mounted. That matters less as proof that it works and more as evidence of how the local network has been treating export applications. Source: Renewable Energy Planning Database, Q1 2026.
