Guardian: Solar power almost doubled in the last year, with 650,000 installations ranging from solar farms to panels on homes, figures showed.
By the end of 2014 there was almost five gigawatts (5GW) of solar photovoltaic panels installed, up from 2.8GW at the end of 2013, the Department of Energy and Climate Change figures showed.
The solar industry said there were now enough panels installed in the UK to supply the equivalent of 1.5m homes.
