Solar panels for farms in Derby
Farm buildings around Derby carry broad, shallow roofs that were put up for storage and stock, not for generation. The survey starts on the covering: fibre cement or steel, its remaining life, the purlin spacing and what the frame will carry.
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.

Solar for agricultural buildings across Derbyshire
What a farm roof near Derby 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 areas we cover, so what decides the scheme is your own demand pattern rather than the latitude.
4 roof mounted schemes are on record nearby. Roof arrays under a megawatt frequently never reach that database at all, so the real number of farm roofs generating around Derby is higher than the record shows.
Surveys run across DE postcodes, DE1 outward.
Derby is the planning authority for most holdings here, and it is the authority that decides whether an array on an agricultural building falls inside permitted development.
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 farm 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 farm roof near 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 shading losses. A building of roughly 1,485 sqm of clear roof carries it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Will the rural network around Derby take the export?
- 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. Rural supplies are often the binding constraint, so we ask the question before an array is sized.
- Is planning permission needed for panels on a farm building near Derby?
- Usually permitted development covers a roof array. Ground mounted arrays are a different question and are far more likely to need a full application. We put both to Derby before design sign-off.
- Has anyone near DE1 already done this?
- The planning database records 0 ground mounted and 4 roof mounted solar schemes in this postcode district. That matters less as proof it works and more as evidence of how the local network has treated export applications. Roof arrays under a megawatt often never appear in the database, so the real figure is higher. Source: Renewable Energy Planning Database, Q1 2026.
