Solar panels for warehouses in Barnstaple
The economics of a Barnstaple 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.
908 kWh per kWp a year at this latitude, so a 500 kWp array models at about 454,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Barnstaple actually generates
Modelled irradiation at this latitude is 1155 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 908 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 Barnstaple clusters on A361 and A39, which is where the large single-let roofs are.
Most of the units we look at here sit in the EX postcode area.
North Devon is the planning authority for most sites here, and the built-up area holds a population of about 31,275, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Barnstaple ranks 7 of 8 towns we cover in Devon on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 903 to 961, a spread of 58 kWh per kWp. On a 500 kWp array that is about 29,000 kWh a year between the strongest and weakest town in the county.

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.

Grid connection through National Grid Electricity Distribution
National Grid Electricity Distribution is the network operator here, and their answer on export capacity shapes the design. Any commercial array above 3.68 kW per phase connects under G99 rather than G98, and the application fixes what you are allowed to push back onto the network. If the local network is tight, limiting export rarely breaks the case here: most of the generation is consumed on site while the building is working.
Across Devon the planning database records 248 solar schemes totalling 1451 MW, of which 90 are operational (REPD Q1 2026).

Questions about solar in Barnstaple
- Is there enough sun in Barnstaple to make this work?
- Modelled at 908 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 454,000 kWh a year before shading. That array needs about 1,485 sqm of clear roof once walkways and setbacks are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Who do we apply to for export in Barnstaple?
- Capacity varies street by street, and only National Grid Electricity Distribution can answer it for your connection. We ask the question early, because an export-limited offer changes the design rather than killing the scheme.
- Do we need planning permission in North Devon?
- In most cases no, because roof-mounted panels on commercial buildings sit within permitted development. The exceptions are listed buildings, conservation areas and arrays that stand proud of the roof plane. We check with North Devon first either way.
- Has anyone near EX32 already done this?
- The planning database records 2 solar schemes in this postcode district. 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.
