Solar panels for warehouses in Newquay
The economics of a Newquay rooftop array turn on how much of the generation the occupier uses on site. Each survey records the cladding profile, the usable area once rooflights and plant are removed, and the export limit worth applying for.
940 kWh per kWp a year at this latitude, so a 500 kWp array models at about 470,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Warehouse rooftop solar across Cornwall
What a roof in Newquay actually generates
Modelled irradiation at this latitude is 1194 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 940 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 6 percent above the mean across the towns we cover, which is as good as UK rooftop gets outside the south coast.
Most of the units we look at here sit in the TR postcode area.
Cornwall is the planning authority for most sites here, and the built-up area holds a population of about 24,545, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Newquay ranks 3 of 8 towns we cover in Cornwall on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 921 to 979, 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.

| Scheme | Operator | Capacity | Mounting | Status |
|---|---|---|---|---|
| Treloggan Road - Solar Panels | WM Morrisons Supermarkets Plc | 0.37 MW | Roof | Awaiting Construction |
| Headland Hotel, Headland Road - Solar Panels | The Headland Hotel | 0.18 MW | Ground | Application Refused |
Grid connection through National Grid Electricity Distribution
National Grid Electricity Distribution operates the distribution network across Cornwall, 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 Cornwall the planning database records 174 solar schemes totalling 1116 MW, of which 88 are operational (REPD Q1 2026).

Questions about solar in Newquay
- How much does a warehouse roof in Newquay generate?
- The model gives 940 kWh for every kWp installed here, so 500 kWp comes out at about 470,000 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 Newquay have capacity?
- National Grid Electricity Distribution is the distribution network operator for Cornwall. 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 Newquay unit?
- Usually permitted development covers it. We still put the question to Cornwall before design sign-off, and we tell you early if a full application is needed rather than discovering it late.
- Has anyone near TR7 already done this?
- The planning database records 2 solar schemes in this postcode district, 1 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.
