Solar panels for warehouses in Penrith
The economics of a Penrith 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.
794 kWh per kWp a year at this latitude, so a 500 kWp array models at about 397,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Warehouse rooftop solar across Cumbria
What a roof in Penrith actually generates
Modelled irradiation at this latitude is 1010 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 794 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 10 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.
Most of the units we look at here sit in the CA postcode area.
Eden is the planning authority for most sites here, and the built-up area holds a population of about 16,700, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Penrith ranks 5 of 6 towns we cover in Cumbria on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 793 to 893, a spread of 100 kWh per kWp. On a 500 kWp array that is about 50,000 kWh a year between the strongest and weakest town in the county.

Grid connection through Electricity North West
Electricity North West 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 Cumbria the planning database records 86 solar schemes totalling 574 MW, of which 17 are operational (REPD Q1 2026).

Questions about solar in Penrith
- Is there enough sun in Penrith to make this work?
- Modelled at 794 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 397,000 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 Penrith?
- Capacity varies street by street, and only Electricity North West 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 Eden?
- 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 Eden first either way.
- Has anyone near CA11 already done this?
- The planning database records 6 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.
