So how much sun do we get in the UK? Using this tool [1] I created graphics for the average mid-day intensity of sunlight month-by-month and also the total monthly sunlight received
The sunlight intensity around noon averaged 700 W/m² over May 2016 making it the sunniest month that year although individual day had more intense noon sunshine. Sunlight intensity exceeded 1,000 W per square metre on 36 days; but on no day did it reach 1,100 W. Note that the rated power of a solar PV panel is based on it receiving 1,000 W of sunlight. So for example RS Components Model 9046156[2] measuring 1.49m x 0.67m (area of 1 square metre) is rated 150 Wp (p standing for 'peak') with an implied efficiency of 15%
