Commercial building solar panels in Peterborough
For a landlord in Peterborough, a roof array is increasingly a question about the EPC rating as much as the electricity bill. The survey starts with the membrane and the deck: how many years the covering has left, what the roof can carry in ballast, and where plant and its shade rule panels out.
898 kWh per kWp a year at this latitude, so a 210 kWp array models at about 189,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Solar for offices and retail across Cambridgeshire
How much sun a Peterborough roof gets
Modelled irradiation here is 1,149 kWh per square metre a year on a low-tilt array, which works out at 898 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is within a few percent of the mean across the towns we cover, so the weather is not what decides the case here. Opening hours are.
The rating list for Peterborough
The Valuation Office Agency's rating list puts 1,370 office and 1,420 retail properties in Peterborough, covering about 328,000 and 382,000 square metres of floorspace respectively. By office stock the district sits above the median of the 318 districts in England and Wales; by retail stock it sits above the median of the 318 districts in England and Wales.
70 of those retail properties are superstores, large food stores, large shops or retail warehouses, together about 196,000 square metres. Single storey boxes of that size are where most commercial rooftop solar actually gets built, because the roof is big, flat or shallow, and uninterrupted.
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.

Commercial rooftop solar already planned near Peterborough
The Renewable Energy Planning Database records 2 roof-mounted schemes on dealership and leisure and hospitality buildings in this postcode district. These are other organisations' projects, listed from the public record, not ours.
| Scheme | Applicant | Type | Capacity | Status |

The built-up area holds about 190,605 people, large enough for a retail park or two and a cluster of office buildings (ONS Census 2021 built-up areas).
Surveys run across PE postcodes, PE3 outward.
Peterborough ranks 7 of 8 towns we cover in Cambridgeshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 898 to 908, a spread of 10 kWh per kWp. Within Cambridgeshire 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
Connections around Peterborough 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 commercial building uses most of what the roof makes during the working day.
Across Cambridgeshire the planning database records 172 solar schemes totalling 2422 MW, of which 46 are operational (REPD Q1 2026).

Questions about solar in Peterborough
- What would a 210 kWp array produce in Peterborough?
- Yes. At 898 kWh per kWp a year, a 210 kWp array on a Peterborough roof models at around 189,000 kWh. What changes the answer is how much of that the building uses during opening hours rather than exports. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Is planning permission needed for panels on a Peterborough office or shop?
- 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 Peterborough 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.
- Will rooftop solar improve the EPC rating of a let building in Peterborough?
- 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.
- Does the grid around Peterborough have capacity for export?
- UK Power Networks is the distribution network operator for Cambridgeshire. Arrays above 3.68 kW per phase connect under G99, and the application sets the export limit. It is part of the design work we arrange.
