Solar panels for warehouses in Norwich
The economics of a Norwich 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.
904 kWh per kWp a year at this latitude, so a 500 kWp array models at about 452,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Warehouse rooftop solar across Norfolk
What a roof in Norwich actually generates
Modelled irradiation at this latitude is 1156 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 904 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 Norwich clusters on A11, A47 and A140, which is where the large single-let roofs are.
Most of the units we look at here sit in the NR postcode area.
Norwich is the planning authority for most sites here, and the built-up area holds a population of about 200,770, the size that tends to be served by mid-box last-mile units rather than national hubs (ONS Census 2021 built-up areas).
Norwich ranks 5 of 8 towns we cover in Norfolk on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 897 to 923, a spread of 26 kWh per kWp. Within Norfolk that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.
Grid connection through UK Power Networks
UK Power Networks 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 Norfolk the planning database records 179 solar schemes totalling 1490 MW, of which 43 are operational (REPD Q1 2026).

Lenzie Consulting Ltd arranges the survey and passes your details to our MCS-certified installation partner so they can quote.
Questions about solar in Norwich
- What would a 500 kWp array produce in Norwich?
- Yes, and the number matters more than the sunshine. At 904 kWh per kWp a year, a 500 kWp array on a Norwich roof models at around 452,000 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 Norwich?
- Applications go to UK Power Networks, who run the network across Norfolk. They decide the export limit, and we handle the G99 paperwork alongside the array design.
- What does Norwich 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 Norwich before the design is finalised.
