How much would solar on a commercial building in Doncaster generate?

The model gives 856 kWh for every kWp installed here, so 210 kWp is about 180,000 kWh a year before shading losses. Allow roughly 1,390 m² of roof for it. 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 Doncaster?

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 Doncaster 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 Doncaster 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 Doncaster?

Capacity varies street by street and only Northern Powergrid 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.

Commercial building solar panels in Doncaster

A flat commercial roof in Doncaster 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.

856 kWh per kWp a year at this latitude, so a 210 kWp array models at about 180,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a flat roof in Doncaster generates

Modelled irradiation here is 1,095 kWh per square metre a year on a low-tilt array, which works out at 856 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 3 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 Doncaster

Doncaster has 1,590 office premises and 2,970 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 top quarter of the 318 districts in England and Wales; by retail stock it sits in the top quarter of the 318 districts in England and Wales.

The big roofs are in the 140 large-format retail units, superstores and retail warehouses in the district, about 251,000 square metres of floorspace under largely single storey roofs.

The same list carries 430 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.

The built-up area holds about 87,455 people, large enough for a retail park or two and a cluster of office buildings (ONS Census 2021 built-up areas).

We arrange surveys across the DN postcode area, starting from DN4.

FIG. 1 What a Doncaster roof makes, month by month

May produces 6.3 times what Dec does on the same roof. A 210 kWp array here models at about 180,000 kWh across the year, but it arrives unevenly, which is why we size against your summer daytime load and then look at whether storage is worth adding for the shoulder months.

Doncaster ranks 1 of 6 towns we cover in South Yorkshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 830 to 856, a spread of 26 kWh per kWp. Within South Yorkshire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.

Bars are zero based, so length is proportional to the figure. Where a county is flat, that is the finding: location is not the lever, consumption is. Source: EU PVGIS v5.2, modelled per town

Grid connection through Northern Powergrid

Connections around Doncaster are handled by Northern Powergrid, 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 South Yorkshire the planning database records 93 solar schemes totalling 1624 MW, of which 8 are operational (REPD Q1 2026).
