Commercial building solar panels in Aldershot
Most commercial roofs around Aldershot already carry plant, a parapet and an access hatch, and the space between them is where the array goes. Each survey records the usable area once edge strips, plant and walkways are taken out, the load the deck can take, and whether the lease lets the occupier alter the roof.
903 kWh per kWp a year at this latitude, so a 210 kWp array models at about 190,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Commercial rooftop solar across Hampshire
Yield on a Aldershot commercial roof
Modelled irradiation here is 1,158 kWh per square metre a year on a low-tilt array, which works out at 903 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.
How many commercial buildings Rushmoor has
On the Valuation Office Agency's count, Rushmoor holds 720 retail and 810 office properties on the rating list. 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.
50 of those retail properties are superstores, large food stores, large shops or retail warehouses, together about 90,000 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 100 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 39,825 people, so the stock here runs to high street premises, a supermarket or two and the odd hotel (ONS Census 2021 built-up areas).

Aldershot ranks 10 of 10 towns we cover in Hampshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 903 to 987, a spread of 84 kWh per kWp. On a 210 kWp commercial roof that is about 17,640 kWh a year between the strongest and weakest town in the county.
Grid connection through Scottish and Southern Electricity Networks
Connections around Aldershot are handled by Scottish and Southern Electricity Networks, 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 Hampshire the planning database records 237 solar schemes totalling 1634 MW, of which 51 are operational (REPD Q1 2026).

Questions about solar in Aldershot
- Is there enough sun in Aldershot for a commercial roof array?
- Modelled at 903 kWh per kWp a year for a low-tilt array at this latitude, a 210 kWp system comes out at roughly 190,000 kWh a year before shading. It needs about 1,390 m² of flat roof once the edge strip, plant and walkways are kept clear. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Is planning permission needed for panels on a Aldershot 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 Rushmoor 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 Aldershot?
- 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 Aldershot have capacity for export?
- Scottish and Southern Electricity Networks is the distribution network operator for Hampshire. 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.
