Solar panels for warehouses in Tewkesbury
Roof space is the one asset a Tewkesbury unit already owns and rarely uses. What decides a scheme here is the state of the covering and the load path, which is why the survey starts on the roof rather than in a spreadsheet.
878 kWh per kWp a year at this latitude, so a 500 kWp array models at about 439,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Warehouse rooftop solar across Gloucestershire
What a roof in Tewkesbury actually generates
Modelled irradiation at this latitude is 1125 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 878 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 Tewkesbury clusters on M5 J9, M50 J1 and A38, which is where the large single-let roofs are.
Most of the units we look at here sit in the GL postcode area.
Tewkesbury is the planning authority for most sites here, and the built-up area holds a population of about 14,390, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Tewkesbury ranks 5 of 6 towns we cover in Gloucestershire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 870 to 905, a spread of 35 kWh per kWp. Within Gloucestershire 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 Gloucestershire, 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 Gloucestershire the planning database records 207 solar schemes totalling 1592 MW, of which 39 are operational (REPD Q1 2026).

Questions about solar in Tewkesbury
- What would a 500 kWp array produce in Tewkesbury?
- Yes, and the number matters more than the sunshine. At 878 kWh per kWp a year, a 500 kWp array on a Tewkesbury roof models at around 439,000 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 Tewkesbury?
- Applications go to National Grid Electricity Distribution, who run the network across Gloucestershire. They decide the export limit, and we handle the G99 paperwork alongside the array design.
- What does Tewkesbury 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 Tewkesbury before the design is finalised.
- Has anyone near GL20 already done this?
- The planning database records 6 solar schemes in this postcode district, 2 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.
