Solar panels for warehouses in Dereham
What makes a Dereham scheme work is rarely the panels. It is the condition of the roof underneath them. Each survey records the cladding profile, the usable area once rooflights and plant are removed, and the export limit worth applying for.
898 kWh per kWp a year at this latitude, so a 500 kWp array models at about 449,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Dereham actually generates
Modelled irradiation at this latitude is 1151 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 898 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.
Surveys run across NR postcodes, NR19 outward.
Breckland is the planning authority for most sites here, and the built-up area holds a population of about 20,785, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Dereham ranks 6 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.

| Scheme | Operator | Capacity | Mounting | Status |
|---|---|---|---|---|

| Dereham Leisure Centre, Station Road - Solar Panels | Parkwood Leisure Ltd | 0.17 MW | Roof | Awaiting Construction |
Grid connection through UK Power Networks
Connections around Dereham are handled by UK Power Networks, which sets the export limit for the site. Above 3.68 kW per phase the connection runs under G99, so the export limit is agreed in advance rather than assumed. Where the local network is constrained, an export-limited connection usually still makes the scheme work, because a warehouse uses most of what the roof makes during the working day.
Across Norfolk the planning database records 179 solar schemes totalling 1490 MW, of which 43 are operational (REPD Q1 2026).

Questions about solar in Dereham
- How much does a warehouse roof in Dereham generate?
- The model gives 898 kWh for every kWp installed here, so 500 kWp comes out at about 449,000 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 Dereham have capacity?
- UK Power Networks is the distribution network operator for Norfolk. 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 Dereham unit?
- Usually permitted development covers it. We still put the question to Breckland before design sign-off, and we tell you early if a full application is needed rather than discovering it late.
- Has anyone near NR19 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.
