Solar panels for farms in Mumbles
A Mumbles farm buys electricity at the worst rate of the day in exactly the hours its roof could be generating. What decides a farm scheme here is the state of the roof sheets and the incoming supply, which is why the survey looks at both before anyone sizes an array.
921 kWh per kWp a year at this latitude, so a 500 kWp array models at about 461,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Agricultural rooftop solar across Swansea
What a farm roof near Mumbles generates
Modelled irradiation at this latitude is 1169 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 921 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 4 percent above the mean across the areas we cover, which is as strong as UK farm rooftop gets outside the south coast.
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.
Mumbles ranks 1 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 Mumbles
- Is there enough sun around Mumbles to make this work?
- Modelled at 921 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 461,000 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 Mumbles?
- Only National Grid Electricity Distribution 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.
