What would a 210 kWp array produce in Bodmin?

Yes. At 929 kWh per kWp a year, a 210 kWp array on a Bodmin roof models at around 195,000 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.

Do we need planning permission for solar on a commercial building in Cornwall?

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 Cornwall 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 Bodmin 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 Bodmin?

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.

Commercial building solar panels in Bodmin

A flat commercial roof in Bodmin 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.

929 kWh per kWp a year at this latitude, so a 210 kWp array models at about 195,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a flat roof in Bodmin generates

Modelled irradiation here is 1,183 kWh per square metre a year on a low-tilt array, which works out at 929 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 5 percent above the mean across the towns we cover.

Commercial stock in Cornwall

Cornwall has 2,980 office premises and 5,750 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 tenth of the 318 districts in England and Wales; by retail stock it sits in the top tenth of the 318 districts in England and Wales.

The big roofs are in the 160 large-format retail units, superstores and retail warehouses in the district, about 418,000 square metres of floorspace under largely single storey roofs.

The same list carries 1,890 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 Bodmin

The Renewable Energy Planning Database records one roof-mounted scheme on supermarket and retail buildings in this postcode district. These are other organisations' projects, listed from the public record, not ours.

Scheme	Applicant	Type	Capacity	Status
Morrisons, Priory Road	Morrisons	retail	0.27 MW	Awaiting Construction

The built-up area holds about 16,910 people, so the stock here runs to high street premises, a supermarket or two and the odd hotel (ONS Census 2021 built-up areas).

We arrange surveys across the PL postcode area, starting from PL31.

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

Jun produces 5.8 times what Dec does on the same roof. A 210 kWp array here models at about 195,000 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.

Bodmin ranks 6 of 8 towns we cover in Cornwall on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 921 to 979, a spread of 58 kWh per kWp. On a 210 kWp commercial roof that is about 12,180 kWh a year between the strongest and weakest town in the county.

Grid connection through National Grid Electricity Distribution

National Grid Electricity Distribution operates the distribution network across Cornwall, 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 Cornwall the planning database records 174 solar schemes totalling 1116 MW, of which 88 are operational (REPD Q1 2026).
