Solar panels for farms in Leatherhead
Around Leatherhead the constraint is rarely the roof. It is the incoming supply and what the network will accept back. The survey starts on the covering: fibre cement or steel, its remaining life, the purlin spacing and what the frame will carry.
910 kWh per kWp a year at this latitude, so a 500 kWp array models at about 455,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Solar for agricultural buildings across Surrey
What a farm roof near Leatherhead generates
Modelled irradiation at this latitude is 1167 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 910 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 areas we cover, so what decides the scheme is your own demand pattern rather than the latitude.
No solar scheme is recorded in this postcode district in the planning database. On a farm that usually means nothing has been built above the reporting threshold rather than that nothing has been built, because a roof array on a shed rarely appears in it.
Surveys run across KT postcodes, KT22 outward.
Mole Valley is the planning authority for most holdings here, and it is the authority that decides whether an array on an agricultural building falls inside permitted development.
Leatherhead ranks 3 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 Leatherhead
- Is there enough sun around Leatherhead to make this work?
- Modelled at 910 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 455,000 kWh a year before shading. That array needs about 1,485 sqm of clear roof once ridge vents and walkways are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Who do we apply to for export near Leatherhead?
- Only UK Power Networks can answer it for your connection, and on rural feeders the answer varies farm to farm. An export-limited offer usually still works, because a holding with grain drying, cooling or ventilation uses most of what it makes.
- Do we need planning permission in Mole Valley?
- In most cases no, because panels on the roof of an agricultural building usually sit within permitted development. The exceptions are listed buildings, conservation areas, protected landscapes and arrays that stand proud of the roof. We check with Mole Valley either way.
