Highly reflecting The highly reflecting specular surfaces are a key component of concentrating solar specular surfaces ­ ystems. They concentrate the solar radiation precisely to achieve extreme energy densites. s By using mirrors with their outstanding reflecting properties the performance can be increased significantly in concentrating parabolic systems (CSP) for the generation of solar thermal electricity, or process heat for industrial applications, air conditioning or sea water desalination. Performance improvements can also be reached by using mirrors in combinations with flat plate...

Photovoltaic installations can benefit from enhanced sunlight exposure by incorporating in their Photovoltaic systems, design mirrors to re-direct energy onto the cell surfaces. A number of designs have been solar thermal and developed to improve PV array output, ranging from full parabolic systems and tracking modules to secondary reflectors simple side reflectors on fixed arrays. , For large parabolic reflectors for process heat generation demanding high performance, with 90% solar reflectance, is the right choice. For smaller reflectors, for instance concentrators for vacuum tube arrays...
