What would a 210 kWp array produce in Hessle?

Yes. At 868 kWh per kWp a year, a 210 kWp array on a Hessle roof models at around 182,000 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 Hessle 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 East Riding of Yorkshire 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 Hessle?

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 Hessle have capacity for export?

Northern Powergrid is the distribution network operator for East Riding of Yorkshire. 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 Hessle

For a landlord in Hessle, 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.

868 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 East Riding of Yorkshire

How much sun a Hessle roof gets

Modelled irradiation here is 1,108 kWh per square metre a year on a low-tilt array, which works out at 868 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 East Riding of Yorkshire

The Valuation Office Agency's rating list puts 1,630 office and 2,880 retail properties in East Riding of Yorkshire, covering about 217,000 and 474,000 square metres of floorspace respectively. 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.

60 of those retail properties are superstores, large food stores, large shops or retail warehouses, together about 133,000 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 690 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 Renewable Energy Planning Database records one roof-mounted scheme on office and business park buildings in this postcode district. These are other organisations' projects, listed from the public record, not ours.

The built-up area holds about 15,485 people, so the stock here runs to high street premises, a supermarket or two and the odd hotel (ONS Census 2021 built-up areas).

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

May produces 6.8 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.

Hessle ranks 2 of 6 towns we cover in East Riding of Yorkshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 858 to 870, a spread of 12 kWh per kWp. Within East Riding of 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

Northern Powergrid is the network operator here, and their answer on export capacity shapes the design. Any commercial array above 3.68 kW per phase connects under G99 rather than G98, and the application fixes what you are allowed to push back onto the network. If the local network is tight, limiting export rarely breaks the case here: most of the generation is consumed on site while the building is working.

Across East Riding of Yorkshire the planning database records 86 solar schemes totalling 1439 MW, of which 2 are operational (REPD Q1 2026).
