Stellio Heliostat

© Filmfabrik Schwaben

Stellio is an innovative heliostat developed by sbp sonne in collaboration with our partners Ingemetal and Masermic. Stellio is a paradigm shift. Its new axis arrangement allows the use of cost-efficient linear actuators for both axes, providing a cost-effective pentagonal structure. Its appropriate size and precise optics at low manufacturing costs result in a significantly improved cost/performance ratio.
