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 that allows the use of costefficient linear actuators for both axis, the cost-effective pentagonal structure, its appropriate size and precise optics at low manufacturing costs result in a significantly improved cost/performance ratio.
