Commercial building solar panels in Weybridge
For a landlord in Weybridge, a roof array is increasingly a question about the EPC rating as much as the electricity bill. 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.
905 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.

Solar for offices and retail across Surrey
How much sun a Weybridge roof gets
Modelled irradiation here is 1,161 kWh per square metre a year on a low-tilt array, which works out at 905 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 Elmbridge
The Valuation Office Agency's rating list puts 960 office and 1,110 retail properties in Elmbridge, covering about 179,000 and 166,000 square metres of floorspace respectively. By office stock the district sits above the median of the 318 districts in England and Wales; by retail stock it sits below the median of the 318 districts in England and Wales.
10 of those retail properties are superstores, large food stores, large shops or retail warehouses, together about 49,000 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 220 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 Weybridge
The Renewable Energy Planning Database records one roof-mounted scheme on leisure and hospitality buildings in this postcode district. These are other organisations' projects, listed from the public record, not ours.
| Scheme | Applicant | Type | Capacity | Status |
|---|---|---|---|---|
| David Lloyd Leisure, Brooklands Road | David Lloyd Leisure Limited | leisure | n/a | Awaiting Construction |
The built-up area holds about 15,915 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 KT postcodes, KT13 outward.
Weybridge ranks 6 of 10 towns we cover in Surrey on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 900 to 916, a spread of 16 kWh per kWp. Within Surrey that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.

Grid connection through UK Power Networks
Connections around Weybridge are handled by UK Power 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 Surrey the planning database records 74 solar schemes totalling 182 MW, of which 6 are operational (REPD Q1 2026).

Questions about solar in Weybridge
- Is there enough sun in Weybridge for a commercial roof array?
- Modelled at 905 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 Weybridge 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 Elmbridge 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 Weybridge?
- 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 Weybridge have capacity for export?
- UK Power Networks is the distribution network operator for Surrey. 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.
