Solar panels for farms in Grantham
A Grantham farm buys electricity at the worst rate of the day in exactly the hours its roof could be generating. 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.
886 kWh per kWp a year at this latitude, so a 500 kWp array models at about 443,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Agricultural rooftop solar across Lincolnshire
What a farm roof near Grantham generates
Modelled irradiation at this latitude is 1130 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 886 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.
The planning record lists 2 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 49.9 MW, with the largest at 49.99 MW. Source: Renewable Energy Planning Database, Q1 2026.
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 Grantham is higher than the record shows.
Most of the buildings we look at here sit in the NG postcode area.
South Kesteven 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.
Grantham ranks 6 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 Grantham
- What would a 500 kWp array produce on a farm near Grantham?
- Yes, and the figure matters more than the sunshine. At 886 kWh per kWp a year, a 500 kWp array on a Grantham holding models at around 443,000 kWh. What changes the answer is how much of that the farm uses itself. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Which network operator handles the connection around Grantham?
- Applications go to National Grid Electricity Distribution, who run the network across Lincolnshire. On a farm the incoming supply matters as much as their answer: a single phase supply caps what can be installed whatever the roof would take.
- What does South Kesteven require for solar on an agricultural building?
- Roof-mounted panels on an agricultural building often fall under permitted development, subject to limits on projection above the roof plane and to the building not being listed or in a conservation area or National Park. We confirm the position with South Kesteven before the design is finalised.
- Has anyone near NG31 already done this?
- The planning database records 2 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.
