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

The model gives 866 kWh for every kWp installed here, so 210 kWp is about 182,000 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.

Is planning permission needed for panels on a Nuneaton 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 Nuneaton and Bedworth 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 Nuneaton?

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 Nuneaton have capacity for export?

National Grid Electricity Distribution is the distribution network operator for Warwickshire. 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.

Commercial building solar panels in Nuneaton

For a landlord in Nuneaton, 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.

866 kWh per kWp a year at this latitude, so a 210 kWp array models at about 182,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Solar for offices and retail across Warwickshire

How much sun a Nuneaton roof gets

Modelled irradiation here is 1,107 kWh per square metre a year on a low-tilt array, which works out at 866 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 Nuneaton and Bedworth

The Valuation Office Agency's rating list puts 350 office and 900 retail properties in Nuneaton and Bedworth, covering about 63,000 and 144,000 square metres of floorspace respectively. 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.

40 of those retail properties are superstores, large food stores, large shops or retail warehouses, together about 31,000 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 130 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 88,815 people, large enough for a retail park or two and a cluster of office buildings (ONS Census 2021 built-up areas).

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

Jul produces 6.0 times what Dec does on the same roof. A 210 kWp array here models at about 182,000 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.

Nuneaton ranks 6 of 7 towns we cover in Warwickshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 866 to 893, a spread of 27 kWh per kWp. Within Warwickshire 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

Every scheme in this postcode district in the government's Renewable Energy Planning Database, Q1 2026, ground and roof mounted, commercial or not. None of them is ours. Together they are a fair guide to how the local network has been treating export applications.

Grid connection through National Grid Electricity Distribution

National Grid Electricity Distribution operates the distribution network across Warwickshire, so the export application goes to them. Anything larger than 3.68 kW per phase falls under G99, which means an application before commissioning rather than a notification afterwards. A constrained network is not the end of a scheme. Capping export costs little when the building already absorbs most of what the roof produces.

Across Warwickshire the planning database records 94 solar schemes totalling 1201 MW, of which 18 are operational (REPD Q1 2026).
