Commercial building solar panels in Market Harborough
Whether solar pays on a Market Harborough commercial building depends less on the panels than on who owns the roof and who pays the 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.
891 kWh per kWp a year at this latitude, so a 210 kWp array models at about 187,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Solar PV for commercial property across Leicestershire
What a flat roof in Market Harborough generates
Modelled irradiation here is 1,136 kWh per square metre a year on a low-tilt array, which works out at 891 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.
Commercial stock in Harborough
Harborough has 740 office premises and 590 shops and other retail premises on the non-domestic rating list, according to the Valuation Office Agency. By office stock the district sits below the median of the 318 districts in England and Wales; by retail stock it sits in the bottom quarter of the 318 districts in England and Wales.
30 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 200 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 24,165 people, so the stock here runs to high street premises, a supermarket or two and the odd hotel (ONS Census 2021 built-up areas).
Surveys run across LE postcodes, LE16 outward.
Market Harborough ranks 1 of 7 towns we cover in Leicestershire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 863 to 891, a spread of 28 kWh per kWp. Within Leicestershire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.

Grid connection through National Grid Electricity Distribution
National Grid Electricity Distribution operates the distribution network across Leicestershire, 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 Leicestershire the planning database records 165 solar schemes totalling 1259 MW, of which 37 are operational (REPD Q1 2026).

Questions about solar in Market Harborough
- What would a 210 kWp array produce in Market Harborough?
- Yes. At 891 kWh per kWp a year, a 210 kWp array on a Market Harborough roof models at around 187,000 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 Market Harborough 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 Harborough 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 Market Harborough?
- 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 Market Harborough have capacity for export?
- National Grid Electricity Distribution is the distribution network operator for Leicestershire. 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.
