Solar tiles, solar glass, solar facades, solar roofs, and in-roof systems are growing in popularity due to their ability to take the place of building elements whilst generating electricity and reducing running costs of the building.

Leading architects are no longer confining themselves to solar tiles and complete solar roofs, they are also specifying solar in atriums, in windows, as solar cladding, on bus stops and in car parks....

Our updated Guide to Building Integrated Photovoltaics will keep you ahead of the game, featuring:
