SolTech’s innovative solution combines an aesthetically pleasing, durable roof with a solar thermal system that works with all central heating types. Made of highly transparent glass, Sigma tiles mimic the size and shape of traditional clay tiles. A solar array comprised of SolTech’s interconnected, liquid-based absorber modules can be installed underneath a roof of these tiles. Harvested solar energy is routed to a storage tank, which connects to the building’s central heating system.
