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.
A paradigm shift in the evolution of heliostats
Stellio is sbp sonne’s innovative heliostat developed in collaboration with our partners Ingemetal and Masermic. This heliostat has a pentagonal shape which allows for dense heliostat field layouts with little shading and blocking and reduced atmospheric attenuation compared to rectangular heliostats. Its new axis arrangement allows the use of cost-efficient linear actuators for both axes, while the appropriate size and precise optics at low manufacturing costs result in a significantly improved cost/performance ratio.
Moreover, large structural deformations at the reflector corners do not happen with Stellio due to the equal-stiffness rotational symmetric structural concept. Standard float-glass mirrors are assembled in jigs using a smart technology to compensate steel-work inaccuracies. The result is a very precise concentrator.
