Solar panels for warehouses in Farnham
Roof space is the one asset a Farnham unit already owns and rarely uses. We start with the covering and the structure, because a roof with five years left in it changes the answer entirely.
903 kWh per kWp a year at this latitude, so a 500 kWp array models at about 452,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Warehouse rooftop solar across Surrey
What a roof in Farnham actually generates
Modelled irradiation at this latitude is 1158 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 903 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That sits within a few percent of the mean across the towns we cover, so the case rests on your consumption pattern rather than on the weather.
Most of the units we look at here sit in the GU postcode area.
Waverley is the planning authority for most sites here, and the built-up area holds a population of about 20,500, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Farnham ranks 7 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
UK Power Networks operates the distribution network across Surrey, 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 Surrey the planning database records 74 solar schemes totalling 182 MW, of which 6 are operational (REPD Q1 2026).

Questions about solar in Farnham
- How much does a warehouse roof in Farnham generate?
- The model gives 903 kWh for every kWp installed here, so 500 kWp comes out at about 452,000 kWh a year before any shading losses. You need roughly 1,485 sqm of clear roof to fit it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Does the grid around Farnham have capacity?
- UK Power Networks is the distribution network operator for Surrey. Anything above 3.68 kW per phase connects under G99, and the application sets the export limit. We submit it as part of the design.
- Is planning permission needed for panels on a Farnham unit?
- Usually permitted development covers it. We still put the question to Waverley before design sign-off, and we tell you early if a full application is needed rather than discovering it late.
- Has anyone near GU9 already done this?
- The planning database records 5 solar schemes in this postcode district, 5 of them roof mounted. That matters less as proof that it works and more as evidence of how the local network has been treating export applications. Source: Renewable Energy Planning Database, Q1 2026.
