Solar panels for warehouses in Leamington Spa

Sheds around Leamington Spa tend to have more roof than the business has any other use for. We start with the covering and the structure, because a roof with five years left in it changes the answer entirely.

What a roof in Leamington Spa actually generates

Modelled irradiation at this latitude is 1127 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 880 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 Leamington Spa clusters on M40 J13, M40 J14 and A46, which is where the large single-let roofs are.

Jul produces 6.2 times what Dec does on the same roof. A 500 kWp array here models at about 440,000 kWh across the year, but it arrives unevenly, which is why we size against your summer daytime load and then look at whether storage is worth adding for the shoulder months.

Leamington Spa ranks 4 of 7 towns we cover in Warwickshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 866 to 893, a spread of 27 kWh per kWp. Within Warwickshire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.

Bars are zero based, so length is proportional to the figure. Where a county is flat, that is the finding: location is not the lever, consumption is. Source: EU PVGIS v5.2, modelled per town

Grid connection through National Grid Electricity Distribution

Connections around Leamington Spa 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 Warwickshire the planning database records 94 solar schemes totalling 1201 MW, of which 18 are operational (REPD Q1 2026).

Questions about solar in Leamington Spa

What would a 500 kWp array produce in Leamington Spa?
Yes, and the number matters more than the sunshine. At 880 kWh per kWp a year, a 500 kWp array on a Leamington Spa roof models at around 440,000 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 Leamington Spa?
Applications go to National Grid Electricity Distribution, who run the network across Warwickshire. They decide the export limit, and we handle the G99 paperwork alongside the array design.
