Solar panels for warehouses in Wellingborough
Most of the industrial stock around Wellingborough carries a large, shallow-pitched roof that was never asked to do anything. Each survey records the cladding profile, the usable area once rooflights and plant are removed, and the export limit worth applying for.
896 kWh per kWp a year at this latitude, so a 500 kWp array models at about 448,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Wellingborough actually generates
Modelled irradiation at this latitude is 1145 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 896 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.
Distribution stock around Wellingborough clusters on A45, A509 and A510, which is where the large single-let roofs are.
We survey across the NN postcode area, starting from NN8.
North Northamptonshire is the planning authority for most sites here, and the built-up area holds a population of about 54,425, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Wellingborough ranks 3 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
Connections around Wellingborough 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 warehouse uses most of what the roof makes during the working day.
Across Northamptonshire the planning database records 133 solar schemes totalling 1932 MW, of which 25 are operational (REPD Q1 2026).

Questions about solar in Wellingborough
- Is there enough sun in Wellingborough to make this work?
- Modelled at 896 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 448,000 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 Wellingborough?
- 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 North 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 North Northamptonshire first either way.
- Has anyone near NN8 already done this?
- The planning database records 4 solar schemes in this postcode district, 3 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.
