How much does a warehouse roof in Workington generate?

The model gives 835 kWh for every kWp installed here, so 500 kWp comes out at about 418,000 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 Workington have capacity?

Electricity North West is the distribution network operator for Cumbria. 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 Workington unit?

Usually permitted development covers it. We still put the question to Allerdale before design sign-off, and we tell you early if a full application is needed rather than discovering it late.

Has anyone near CA14 already done this?

The planning database records 6 solar schemes in this postcode district, 4 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.

Solar panels for warehouses in Workington

The economics of a Workington 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.

835 kWh per kWp a year at this latitude, so a 500 kWp array models at about 418,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Workington actually generates

Modelled irradiation at this latitude is 1061 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 835 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 6 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 CA postcode area.

Allerdale is the planning authority for most sites here, and the built-up area holds a population of about 21,275, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).

FIG. 1 What a Workington roof makes, month by month

May produces 9.8 times what Dec does on the same roof. A 500 kWp array here models at about 418,000 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.

Workington ranks 3 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.

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

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).
