Solar panels for farms in Neath
Around Neath the constraint is rarely the roof. It is the incoming supply and what the network will accept back. 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.
881 kWh per kWp a year at this latitude, so a 500 kWp array models at about 441,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Farm building solar PV across Swansea
What a farm roof near Neath generates
Modelled irradiation at this latitude is 1127 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 881 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 1.3 MW. Source: Renewable Energy Planning Database, Q1 2026.
We survey holdings across the SA postcode area, starting from SA10.
Neath Port Talbot 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.
Neath ranks 4 of 4 towns we cover in Swansea on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 881 to 921, a spread of 40 kWh per kWp. Within Swansea that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.

Grid connection through National Grid Electricity Distribution
National Grid Electricity Distribution operates the distribution network across Swansea, 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.

Questions about solar in Neath
- What would a 500 kWp array produce on a farm near Neath?
- Yes, and the figure matters more than the sunshine. At 881 kWh per kWp a year, a 500 kWp array on a Neath holding models at around 441,000 kWh. What changes the answer is how much of that the farm uses itself. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Which network operator handles the connection around Neath?
- Applications go to National Grid Electricity Distribution, who run the network across Swansea. On a farm the incoming supply matters as much as their answer: a single phase supply caps what can be installed whatever the roof would take.
- What does Neath Port Talbot require for solar on an agricultural building?
- Roof-mounted panels on an agricultural building often fall under permitted development, subject to limits on projection above the roof plane and to the building not being listed or in a conservation area or National Park. We confirm the position with Neath Port Talbot before the design is finalised.
