Terracotta-look solar roof tiles to bring renewable energy to historical sites
Called Invisible Solar, the roof tile resembles a real terracotta tile, and consists of a module made from a recyclable non-toxic polymeric material specifically processed to encourage the absorption of photons. Common monocrystalline silicon cells are incorporated inside this module, which has a surface that appears opaque to human eyes but allows sunlight to enter and energise the photovoltaic cells.
