What the data says about Swansea
Modelled yield is not flat across Swansea. Mumbles comes out at 921 kWh per kWp a year against 881 at Neath, a spread of 40 kWh per kWp. On a 500 kWp array that difference is about 20,000 kWh a year, which is worth checking before you accept a generic saving figure.
The planning database records no solar schemes for Swansea at present, which usually means the local stock has gone in below the reporting threshold rather than that nothing has been built. Roof arrays under 1 MW frequently never appear in it.
Connections across the county run through National Grid Electricity Distribution. Anything above 3.68 kW per phase needs a G99 application, and the export limit they offer shapes the design, so we ask the question before the array is sized rather than after.
- Neath 881 kWh/kWp
- Morriston 899 kWh/kWp
- Mumbles 921 kWh/kWp
- Sa1 Waterfront
- Sketty 921 kWh/kWp
- Swansea City Centre
