The annual yield for solar PV electricity generation in the UK is calculated for the installed capacity at the end of 2013 and found to be approximately 950 kWh/kWp. The value is derived by averaging expected PV yield in different regions of the UK, weighted according to the installed PV generating capacity by region from UK government published statistics. The mean generating yield can vary with time as newly deployed PV may change the regional distribution of installed power and the variation over the period 2010-2013 is charted. The installed solar PV generating capacity at the end of 2014 was 5.095 GWp and, based on the above yield, should generate around 4840 GWh of electricity in a typical year or 1.5% of UK consumption.
