Solar panels for farms in Chesterfield
Around Chesterfield the constraint is rarely the roof. It is the incoming supply and what the network will accept back. The survey starts on the covering: fibre cement or steel, its remaining life, the purlin spacing and what the frame will carry.
843 kWh per kWp a year at this latitude, so a 500 kWp array models at about 422,000 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 Chesterfield generates
Modelled irradiation at this latitude is 1076 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 843 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 5 percent below the mean across the areas we cover, so the case here rests on using the output on the holding rather than exporting it.
1 roof mounted scheme is on record nearby. Roof arrays under a megawatt frequently never reach that database at all, so the real number of farm roofs generating around Chesterfield is higher than the record shows.
Surveys run across S postcodes, S40 outward.
Chesterfield 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.
Chesterfield ranks 7 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 Chesterfield 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 Chesterfield
- Is there enough sun around Chesterfield to make this work?
- Modelled at 843 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 422,000 kWh a year before shading. That array needs about 1,485 sqm of clear roof once ridge vents and walkways are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Who do we apply to for export near Chesterfield?
- Only National Grid Electricity Distribution can answer it for your connection, and on rural feeders the answer varies farm to farm. An export-limited offer usually still works, because a holding with grain drying, cooling or ventilation uses most of what it makes.
- Do we need planning permission in Chesterfield?
- In most cases no, because panels on the roof of an agricultural building usually sit within permitted development. The exceptions are listed buildings, conservation areas, protected landscapes and arrays that stand proud of the roof. We check with Chesterfield either way.
