Solar panels for warehouses in Shrewsbury
The economics of a Shrewsbury 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.
852 kWh per kWp a year at this latitude, so a 500 kWp array models at about 426,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Warehouse rooftop solar across Shropshire
What a roof in Shrewsbury actually generates
Modelled irradiation at this latitude is 1091 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 852 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 4 percent below the mean across the towns we cover, so the case here leans harder on how much you use on site rather than on raw generation.
Distribution stock around Shrewsbury clusters on A5, A49 and A458, which is where the large single-let roofs are.
Most of the units we look at here sit in the SY postcode area.
Shropshire is the planning authority for most sites here, and the built-up area holds a population of about 76,015, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Shrewsbury ranks 4 of 5 towns we cover in Shropshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 842 to 860, a spread of 18 kWh per kWp. Within Shropshire 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 |
|---|---|---|---|---|
| Sundorne Grove | Elgin Energy EsCo | 20 MW | Ground | Operational |
| Benbow Business Park - Roof Monted Solar PV System | Furrows Group | 0.2 MW | Roof | Awaiting Construction |
| Caterpillar Factory, Lancaster Road - Solar Panels | Caterpillar Shrewsbury Limited | 0.37 MW | Roof | Awaiting Construction |
Grid connection through National Grid Electricity Distribution
National Grid Electricity Distribution operates the distribution network across Shropshire, 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 Shropshire the planning database records 110 solar schemes totalling 813 MW, of which 27 are operational (REPD Q1 2026).

Questions about solar in Shrewsbury
- How much does a warehouse roof in Shrewsbury generate?
- The model gives 852 kWh for every kWp installed here, so 500 kWp comes out at about 426,000 kWh a year before any shading losses. You need roughly 1,485 sqm of clear roof to fit it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Does the grid around Shrewsbury have capacity?
- National Grid Electricity Distribution is the distribution network operator for Shropshire. Anything above 3.68 kW per phase connects under G99, and the application sets the export limit. We submit it as part of the design.
- Is planning permission needed for panels on a Shrewsbury unit?
- Usually permitted development covers it. We still put the question to Shropshire before design sign-off, and we tell you early if a full application is needed rather than discovering it late.
- Has anyone near SY1 already done this?
- The planning database records 3 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.
