Solar panels for warehouses in Matlock
Roof space is the one asset a Matlock unit already owns and rarely uses. We start with the covering and the structure, because a roof with five years left in it changes the answer entirely.
844 kWh per kWp a year at this latitude, so a 500 kWp array models at about 422,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Warehouse rooftop solar across Derbyshire
What a roof in Matlock actually generates
Modelled irradiation at this latitude is 1076 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 844 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 5 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 DE postcode area.
Derbyshire Dales is the planning authority for most sites here, and the built-up area holds a population of about 11,990, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Matlock ranks 6 of 8 towns we cover in Derbyshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 805 to 866, a spread of 61 kWh per kWp. On a 500 kWp array that is about 30,500 kWh a year between the strongest and weakest town in the county.
Grid connection through National Grid Electricity Distribution
Connections around Matlock are handled by National Grid Electricity Distribution, 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 Derbyshire the planning database records 144 solar schemes totalling 904 MW, of which 27 are operational (REPD Q1 2026).

Questions about solar in Matlock
- Is there enough sun in Matlock to make this work?
- Modelled at 844 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 422,000 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 Matlock?
- Capacity varies street by street, and only National Grid Electricity Distribution 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 Derbyshire Dales?
- 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 Derbyshire Dales first either way.
- Has anyone near DE4 already done this?
- The planning database records 6 solar schemes in this postcode district, 3 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.
