Solar panels for farms in Amersham
A Amersham farm buys electricity at the worst rate of the day in exactly the hours its roof could be generating. Each survey records the sheet type and condition, the usable area once rooflights and vents come out, and whether the supply is single or three phase.
890 kWh per kWp a year at this latitude, so a 500 kWp array models at about 445,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Farm building solar PV across Buckinghamshire
What a farm roof near Amersham generates
Modelled irradiation at this latitude is 1143 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 890 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.
We survey holdings across the HP postcode area, starting from HP6.
Buckinghamshire 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.
Amersham ranks 6 of 8 towns we cover in Buckinghamshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 881 to 904, a spread of 23 kWh per kWp. Within Buckinghamshire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.
Grid connection through Scottish and Southern Electricity Networks
Connections around Amersham 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 farm uses most of what the roof makes during the working day.
Across Buckinghamshire the planning database records 127 solar schemes totalling 955 MW, of which 21 are operational (REPD Q1 2026).

Questions about solar in Amersham
- Is there enough sun around Amersham to make this work?
- Modelled at 890 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 445,000 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 Amersham?
- Only Scottish and Southern Electricity 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 Buckinghamshire?
- 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 Buckinghamshire either way.
