Solar panels for farms in Towcester
The case for solar on a Towcester holding turns on how much of the output the farm uses itself, not on how much the roof makes. Each survey records the sheet type and condition, the usable area once rooflights and vents come out, and whether the supply is single or three phase.
897 kWh per kWp a year at this latitude, so a 500 kWp array models at about 449,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Farm building solar PV across Northamptonshire
What a farm roof near Towcester generates
Modelled irradiation at this latitude is 1147 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 897 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 1 ground mounted solar scheme 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 40 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 Towcester is higher than the record shows.
We survey holdings across the NN postcode area, starting from NN12.
West Northamptonshire 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.
Towcester ranks 2 of 7 towns we cover in Northamptonshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 890 to 900, a spread of 10 kWh per kWp. Within Northamptonshire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.

Grid connection through National Grid Electricity Distribution
National Grid Electricity Distribution is the network operator here, and their answer on export capacity shapes the design. Any commercial array above 3.68 kW per phase connects under G99 rather than G98, and the application fixes what you are allowed to push back onto the network. If the local network is tight, limiting export rarely breaks the case here: most of the generation is consumed on site while the building is working.
Across Northamptonshire the planning database records 133 solar schemes totalling 1932 MW, of which 25 are operational (REPD Q1 2026).

Questions about solar in Towcester
- Is there enough sun around Towcester to make this work?
- Modelled at 897 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 449,000 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 Towcester?
- 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 Northamptonshire?
- 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 Northamptonshire either way.
- Has anyone near NN12 already done this?
- The planning database records 1 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.
