The development of PV cells is gathering pace as indicated by the fact that the manufacturing capacity for PVs increased by 56 per cent in Europe and 46 per cent in Japan alone between 2001 and 2002. The greatest potential growth area is with building integrated PVs within facade and roof components. Examples of PV integrated cladding include the adaptation of rain screens, roof tiles and windows.
