Solar panels for warehouses in Preston
A Preston warehouse roof sits idle through exactly the hours its occupier buys the most expensive electricity. What decides a scheme here is the state of the covering and the load path, which is why the survey starts on the roof rather than in a spreadsheet.

What a roof in Preston actually generates
Modelled irradiation at this latitude is 1028 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 805 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 9 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 Preston clusters on M6 J31, M6 J32 and M55 J1, which is where the large single-let roofs are.
Surveys run across PR postcodes, PR1 outward.
Preston is the planning authority for most sites here, and the built-up area holds a population of about 94,490, the size that tends to be served by mid-box last-mile units rather than national hubs (ONS Census 2021 built-up areas).
Preston ranks 3 of 8 towns we cover in Lancashire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 774 to 888, a spread of 114 kWh per kWp. On a 500 kWp array that is about 57,000 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 Lancashire the planning database records 161 solar schemes totalling 521 MW, of which 25 are operational (REPD Q1 2026).

Questions about solar in Preston
- What would a 500 kWp array produce in Preston?
- Yes, and the number matters more than the sunshine. At 805 kWh per kWp a year, a 500 kWp array on a Preston roof models at around 403,000 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 Preston?
- Applications go to Electricity North West, who run the network across Lancashire. They decide the export limit, and we handle the G99 paperwork alongside the array design.
- What does Preston 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 Preston before the design is finalised.
- Has anyone near PR1 already done this?
- The planning database records 2 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.
