Solar panels for warehouses in Yeovil
The economics of a Yeovil rooftop array turn on how much of the generation the occupier uses on site. The survey measures the roof, not the postcode: cladding profile, purlin centres, remaining sheet life and the load the frame can take.
923 kWh per kWp a year at this latitude, so a 500 kWp array models at about 462,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Warehouse rooftop solar across Somerset
What a roof in Yeovil actually generates
Modelled irradiation at this latitude is 1180 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 923 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 4 percent above the mean across the towns we cover, which is as good as UK rooftop gets outside the south coast.
Distribution stock around Yeovil clusters on A30, A37 and A303, which is where the large single-let roofs are.
Most of the units we look at here sit in the BA postcode area.
Dorset is the planning authority for most sites here, and the built-up area holds a population of about 50,170, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Yeovil ranks 3 of 8 towns we cover in Somerset on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 894 to 934, a spread of 40 kWh per kWp. Within Somerset that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.

From the government's Renewable Energy Planning Database, Q1 2026. These are the schemes on record in this postcode district, which is a fair guide to how the local network has been treating export applications.
| Scheme | Operator | Capacity | Mounting | Status |
|---|---|---|---|---|
| Tesco Queensway Place | Push Energy | 0.3 MW | Roof | Operational |
| Westland Leisure Complex | Engie | 0.22 MW | Roof | Operational |
| Morrisons, Lysander Road - Solar Panels | Gondola Pro | 0.37 MW | Roof | Application Refused |
Grid connection through National Grid Electricity Distribution
Connections around Yeovil 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 Somerset the planning database records 223 solar schemes totalling 1574 MW, of which 79 are operational (REPD Q1 2026).

Questions about solar in Yeovil
- What would a 500 kWp array produce in Yeovil?
- Yes, and the number matters more than the sunshine. At 923 kWh per kWp a year, a 500 kWp array on a Yeovil roof models at around 462,000 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 Yeovil?
- Applications go to National Grid Electricity Distribution, who run the network across Somerset. They decide the export limit, and we handle the G99 paperwork alongside the array design.
- What does Dorset 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 Dorset before the design is finalised.
- Has anyone near BA20 already done this?
- The planning database records 3 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.
