Solar panels for farms in Gainsborough
Around Gainsborough the constraint is rarely the roof. It is the incoming supply and what the network will accept back. What decides a farm scheme here is the state of the roof sheets and the incoming supply, which is why the survey looks at both before anyone sizes an array.

Agricultural rooftop solar across Lincolnshire
What a farm roof near Gainsborough generates
Modelled irradiation at this latitude is 1103 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 861 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 3 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.
The planning record lists 5 ground mounted solar schemes in this postcode district, which is a fair guide to how the local network has treated field arrays. The typical consented scheme in this district is about 500 MW, with the largest at 600 MW. Source: Renewable Energy Planning Database, Q1 2026.
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 Gainsborough is higher than the record shows.
Most of the buildings we look at here sit in the DN postcode area.
West Lindsey 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.
Gainsborough ranks 8 of 8 towns we cover in Lincolnshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 861 to 906, a spread of 45 kWh per kWp. On a 500 kWp array that is about 22,500 kWh a year between the strongest and weakest town in the county.

Grid connection through National Grid Electricity Distribution
National Grid Electricity Distribution operates the distribution network across Lincolnshire, 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 Lincolnshire the planning database records 226 solar schemes totalling 7052 MW, of which 37 are operational (REPD Q1 2026).

Questions about solar in Gainsborough
- Is there enough sun around Gainsborough to make this work?
- Modelled at 861 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 431,000 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 Gainsborough?
- 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 West Lindsey?
- 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 West Lindsey either way.
- Has anyone near DN21 already done this?
- The planning database records 5 ground mounted and 1 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.
