Solar panels for warehouses in Dewsbury
Roof space is the one asset a Dewsbury unit already owns and rarely uses. 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.

Warehouse rooftop solar across West Yorkshire
What a roof in Dewsbury actually generates
Modelled irradiation at this latitude is 1064 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 835 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 6 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 WF postcode area.
Leeds is the planning authority for most sites here, and the built-up area holds a population of about 63,720, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Dewsbury ranks 3 of 8 towns we cover in West Yorkshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 811 to 846, a spread of 35 kWh per kWp. Within West Yorkshire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.
Grid connection through Northern Powergrid
Northern Powergrid 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 West Yorkshire the planning database records 170 solar schemes totalling 550 MW, of which 8 are operational (REPD Q1 2026).

Questions about solar in Dewsbury
- What would a 500 kWp array produce in Dewsbury?
- Yes, and the number matters more than the sunshine. At 835 kWh per kWp a year, a 500 kWp array on a Dewsbury roof models at around 418,000 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 Dewsbury?
- Applications go to Northern Powergrid, who run the network across West Yorkshire. They decide the export limit, and we handle the G99 paperwork alongside the array design.
- What does Leeds 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 Leeds before the design is finalised.
- Has anyone near WF12 already done this?
- The planning database records 4 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.
