Solar panels for farms in Henley-on-Thames
The case for solar on a Henley-on-Thames holding turns on how much of the output the farm uses itself, not on how much the roof makes. The survey starts on the covering: fibre cement or steel, its remaining life, the purlin spacing and what the frame will carry.
899 kWh per kWp a year at this latitude, so a 500 kWp array models at about 450,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Solar for agricultural buildings across Oxfordshire
What a farm roof near Henley-on-Thames generates
Modelled irradiation at this latitude is 1153 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 899 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.
The planning record lists 1 ground mounted solar scheme in this postcode district, which is a fair guide to how the local network has treated field arrays. The typical consented scheme in this district is about 0.2 MW. Source: Renewable Energy Planning Database, Q1 2026.
Surveys run across RG postcodes, RG9 outward.
Wokingham 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.
Henley-on-Thames ranks 4 of 8 towns we cover in Oxfordshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 891 to 913, a spread of 22 kWh per kWp. Within Oxfordshire 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 Henley-on-Thames 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 Oxfordshire the planning database records 149 solar schemes totalling 2544 MW, of which 31 are operational (REPD Q1 2026).

Questions about solar in Henley-on-Thames
- How much does a farm roof near Henley-on-Thames generate?
- The model gives 899 kWh for every kWp installed here, so 500 kWp comes out at about 450,000 kWh a year before shading losses. A building of roughly 1,485 sqm of clear roof carries it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Will the rural network around Henley-on-Thames take the export?
- Scottish and Southern Electricity Networks is the distribution network operator for Oxfordshire. Anything above 3.68 kW per phase connects under G99, and the application sets the export limit. Rural supplies are often the binding constraint, so we ask the question before an array is sized.
- Is planning permission needed for panels on a farm building near Henley-on-Thames?
- Usually permitted development covers a roof array. Ground mounted arrays are a different question and are far more likely to need a full application. We put both to Wokingham before design sign-off.
