Solar panels for warehouses in Towcester
Most of the industrial stock around Towcester carries a large, shallow-pitched roof that was never asked to do anything. The survey measures the roof, not the postcode: cladding profile, purlin centres, remaining sheet life and the load the frame can take.
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.

What a roof in Towcester actually 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 towns we cover, so the case rests on your consumption pattern rather than on the weather.
We survey across the NN postcode area, starting from NN12.
West Northamptonshire is the planning authority for most sites here, and the built-up area holds a population of about 11,330, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
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 in 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 walkways and setbacks are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Who do we apply to for export in Towcester?
- Capacity varies street by street, and only National Grid Electricity Distribution can answer it for your connection. We ask the question early, because an export-limited offer changes the design rather than killing the scheme.
- Do we need planning permission in West Northamptonshire?
- In most cases no, because roof-mounted panels on commercial buildings sit within permitted development. The exceptions are listed buildings, conservation areas and arrays that stand proud of the roof plane. We check with West Northamptonshire first either way.
- Has anyone near NN12 already done this?
- The planning database records 5 solar schemes in this postcode district, 4 of them roof mounted. That matters less as proof that it works and more as evidence of how the local network has been treating export applications. Source: Renewable Energy Planning Database, Q1 2026.
