What the data says about Cardiff
Modelled yield is not flat across Cardiff. Canton comes out at 936 kWh per kWp a year against 908 at Splott, a spread of 28 kWh per kWp. On a 500 kWp array that difference is about 14,000 kWh a year, which is worth checking before you accept a generic saving figure.
The planning database records no solar schemes for Cardiff 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.
