Solar panels for farms in Cwmbrân
Around Cwmbrân 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.
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.

Solar for agricultural buildings across Newport
What a farm roof near Cwmbrân generates
Modelled irradiation at this latitude is 1159 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 areas we cover, so what decides the scheme is your own demand pattern rather than the latitude.
The planning record lists 4 ground mounted solar schemes 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 4 MW, with the largest at 20 MW. Source: Renewable Energy Planning Database, Q1 2026.
1 roof mounted scheme is on record nearby. Roof arrays under a megawatt frequently never reach that database at all, so the real number of farm roofs generating around Cwmbrân is higher than the record shows.
Surveys run across NP postcodes, NP44 outward.
Torfaen 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.
Cwmbrân ranks 3 of 4 towns we cover in Newport on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 887 to 910, a spread of 23 kWh per kWp. Within Newport that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.

Questions about solar in Cwmbrân
- Is there enough sun around Cwmbrân to make this work?
- Modelled at 903 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 452,000 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.
- Do we need planning permission in Torfaen?
- 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 Torfaen either way.
- Has anyone near NP44 already done this?
- The planning database records 4 ground mounted and 1 roof mounted solar schemes in this postcode district. That matters less as proof it works and more as evidence of how the local network has treated export applications. Roof arrays under a megawatt often never appear in the database, so the real figure is higher. Source: Renewable Energy Planning Database, Q1 2026.
