Photovoltaic cells are panels made from one or two layers of semi-conducting material, like silicon, that you can attach to your roof or walls. When light shines on them it creates an electric field across the layers. Although they work on a cloudy day basically the stronger the sunshine the more electricity is produced.
Solar panels that produce electricity have not proved popular in London so far but this is changing rapidly. Their high relative cost to energy output has meant that they have largely been used on flagship projects or as a means of satisfying planning criteria for new-builds.
However the recently announced proposed feed-in-tariffs (FIT) that are due to begin in April 2010 dramatically improve the economics of putting solar panels on your roof and generating your own electricity.
