Commercial building solar panels in Matlock
A flat commercial roof in Matlock is usually the largest surface a building owns and the one nobody is asked to manage. We check the covering and the lease together, because a roof with eight years of membrane left and a tenant with a break in three changes the answer.
844 kWh per kWp a year at this latitude, so a 210 kWp array models at about 177,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Solar PV for commercial property across Derbyshire
What a flat roof in Matlock generates
Modelled irradiation here is 1,076 kWh per square metre a year on a low-tilt array, 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 rests more on daytime consumption than on raw generation.
Commercial stock in Derbyshire Dales
Derbyshire Dales has 480 office premises and 830 shops and other retail premises on the non-domestic rating list, according to the Valuation Office Agency. By office stock the district sits in the bottom quarter of the 318 districts in England and Wales; by retail stock it sits below the median of the 318 districts in England and Wales.
The big roofs are in the 20 large-format retail units, superstores and retail warehouses in the district, about 20,000 square metres of floorspace under largely single storey roofs.
The same list carries 250 hotel, leisure and assembly properties in the district. Leisure centres and hotels run seven days a week, which puts weekend generation to use that an office would export.

We arrange surveys across the DE postcode area, starting from DE4.
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 210 kWp commercial roof that is about 12,810 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 commercial building 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 for a commercial roof array?
- Modelled at 844 kWh per kWp a year for a low-tilt array at this latitude, a 210 kWp system comes out at roughly 177,000 kWh a year before shading. It needs about 1,390 m² of flat roof once the edge strip, plant and walkways are kept clear. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Do we need planning permission for solar on a commercial building in Derbyshire Dales?
- Usually not a full application. In England, panels on the roof of a non-domestic building are permitted development under Class J of Part 14 of the General Permitted Development Order, with no capacity cap since December 2023. Above 50 kW, which covers most commercial arrays, you must first apply to Derbyshire Dales for a determination on prior approval of the design and appearance, in particular glare on neighbouring land. On a flat roof panels may stand no more than 1 metre above the roof and must sit at least 1 metre from its edge, and listed buildings and scheduled monuments are excluded. See our planning permission guide for the detail.
- Does solar help a Matlock landlord meet MEES?
- It can. A non-domestic EPC is an asset rating, and on-site generation counts in the calculation, so an array usually lifts the score. Let property in England and Wales must be EPC E or better today. The government's interim response of 18 June 2026 proposes EPC B, where cost effective, from 2031 for let buildings over 1,000 m², and drops the EPC C step once planned for 2027. How far solar moves a particular building depends on its fabric and services, which is why the EPC assessor models it before anything is fitted.
- Which network operator handles the connection in Matlock?
- Capacity varies street by street and only National Grid Electricity Distribution can answer it for your connection. We ask early, because an export-limited offer changes the design rather than ending the scheme, and most commercial buildings use most of what they generate anyway.
