Solar panels for warehouses in Derby
What makes a Derby scheme work is rarely the panels. It is the condition of the roof underneath them. Each survey records the cladding profile, the usable area once rooflights and plant are removed, and the export limit worth applying for.
862 kWh per kWp a year at this latitude, so a 500 kWp array models at about 431,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Derby actually generates
Modelled irradiation at this latitude is 1100 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 862 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That sits within a few percent of the mean across the towns we cover, so the case rests on your consumption pattern rather than on the weather.
Distribution stock around Derby clusters on A50, A38 and A52, which is where the large single-let roofs are.
Surveys run across DE postcodes, DE1 outward.
Derby is the planning authority for most sites here, and the built-up area holds a population of about 275,575, which is large enough to pull in the regional distribution centres that come with the biggest roofs (ONS Census 2021 built-up areas).
Derby ranks 2 of 8 towns we cover in Derbyshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 805 to 866, a spread of 61 kWh per kWp. On a 500 kWp array that is about 30,500 kWh a year between the strongest and weakest town in the county.

Grid connection through National Grid Electricity Distribution
Connections around Derby are handled by National Grid Electricity Distribution, 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 Derbyshire the planning database records 144 solar schemes totalling 904 MW, of which 27 are operational (REPD Q1 2026).

Questions about solar in Derby
- How much does a warehouse roof in Derby generate?
- The model gives 862 kWh for every kWp installed here, so 500 kWp comes out at about 431,000 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 Derby have capacity?
- National Grid Electricity Distribution is the distribution network operator for Derbyshire. 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 Derby unit?
- Usually permitted development covers it. We still put the question to Derby before design sign-off, and we tell you early if a full application is needed rather than discovering it late.
- Has anyone near DE1 already done this?
- The planning database records 4 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.
