Solar panels for warehouses in Northampton
Most of the industrial stock around Northampton 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.
893 kWh per kWp a year at this latitude, so a 500 kWp array models at about 447,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Northampton actually generates
Modelled irradiation at this latitude is 1142 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 893 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 Northampton clusters on M1 J15, M1 J15a and M1 J16, which is where the large single-let roofs are.
We survey across the NN postcode area, starting from NN1.
North Northamptonshire is the planning authority for most sites here, and the built-up area holds a population of about 243,520, the size that tends to be served by mid-box last-mile units rather than national hubs (ONS Census 2021 built-up areas).
Northampton ranks 5 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 operates the distribution network across Northamptonshire, 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 Northamptonshire the planning database records 133 solar schemes totalling 1932 MW, of which 25 are operational (REPD Q1 2026).

Questions about solar in Northampton
- What would a 500 kWp array produce in Northampton?
- Yes, and the number matters more than the sunshine. At 893 kWh per kWp a year, a 500 kWp array on a Northampton roof models at around 447,000 kWh. What changes the answer is how much of that you use on site rather than export. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Which network operator handles the connection in Northampton?
- Applications go to National Grid Electricity Distribution, who run the network across Northamptonshire. They decide the export limit, and we handle the G99 paperwork alongside the array design.
- What does North Northamptonshire require for rooftop solar?
- Roof-mounted panels on a commercial building usually fall under permitted development, subject to the limits on projection above the roof plane and to the building not being listed or in a conservation area. We confirm the position with North Northamptonshire before the design is finalised.
