Marley Roofing is a major UK manufacturer of many kinds of roofing products. They have introduced a solar tile system. “The Marley SolarTile™ was designed to integrate with the Marley Modern interlocking tile and is easily installed by fixing to standard batterns. .. Each tile has a PV laminate comprising of 10 BP Solar Saturn cells generating an output of 23Wp. Over the year a suitably orientated installation of 100 Marley Solar Tiles will generate enough electricity for a typical 3 bedroom household (excluding central heating and water heating).
Marley SolarTiles™ are easy to install, use standard battening and are completely modular to meet the requirements of any roofing application. The Solar Tile has just two parts, a Top and a Base. The tile top fits onto the base and contains the photovoltaic elements which generate electricity. The tile base fits onto the roof and provides the electrical connectors to the house wiring.” This would allow the substitution of new PV cells as they are developed.
