Solar panels for warehouses in Ashton-under-Lyne

Sheds around Ashton-under-Lyne 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.

769 kWh per kWp a year at this latitude, so a 500 kWp array models at about 385,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Ashton-under-Lyne actually generates

Modelled irradiation at this latitude is 983 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 769 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 13 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.

We survey across the OL postcode area, starting from OL6.

Oldham is the planning authority for most sites here, and the built-up area holds a population of about 48,600, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).

May produces 7.3 times what Jan does on the same roof. A 500 kWp array here models at about 385,000 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.

Ashton-under-Lyne ranks 10 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.

Bars are zero based, so length is proportional to the figure. Where a county is flat, that is the finding: location is not the lever, consumption is. Source: EU PVGIS v5.2, modelled per town

Grid connection through Electricity North West

Connections around Ashton-under-Lyne are handled by Electricity North West, which sets the export limit for the site. Above 3.68 kW per phase the connection runs under G99, so the export limit is agreed in advance rather than assumed. Where the local network is constrained, an export-limited connection usually still makes the scheme work, because a warehouse uses most of what the roof makes during the working day.

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

Solar already consented near OL6

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.

Questions about solar in Ashton-under-Lyne

How much does a warehouse roof in Ashton-under-Lyne generate?
The model gives 769 kWh for every kWp installed here, so 500 kWp comes out at about 385,000 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 Ashton-under-Lyne 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 Ashton-under-Lyne unit?
Usually permitted development covers it. We still put the question to Oldham before design sign-off, and we tell you early if a full application is needed rather than discovering it late.
