Since the introduction of feed-in tariffs in April last year, Sheffield has adopted more solar power generation per head than any other city in the UK. Published by the AEA Group, the ‘top 10’ authorities in the UK utilising photovoltaic technology are ranked by total output – showing Cornwall as number one, with 3.09MW capacity. Sheffield places at number five with 2.03MW capacity contributing 1.262% to the total microgeneration in the UK. However if the figures are analysed by installed capacity in relation to the population, they tell a different story.
