Taking to use PE,PU materials as the backside board, the super-thin solar mirror with pretty high reflectivity is directly sticked or laminated with this backside board by means of special processing. This finished formed heliostat can be installed on site efficiently. This so-called Sandwich structure will greatly enhance the rigidness and stability of heliostat, and improve the wind-resistance property. Also as the protection of this backside material, this heliostat can significantly resist the sandstorm and corrosion impact. It's front facet with super-thin solar mirror, will greatly improves the concentration efficiency for entire solar filed. Sandwich structure heliostat can be also customized according to client's design, to form certain curvature or radius, enabling to realize much higher concentrating effect. ★ Specification in optimization and customization ★ Pre-assembled backside fixing parts (Ceramic Pad, Al Pad, Stainless steel etc.) ★ Excellent performance to resist strong wind with stability ★ Excellent durability performance resisting sandstorm,corrosion ★ Safety, hard-to-break, remaining working even it’s breakage no big effect of its performance ★ Specially designed packaging, easy logistic and transportation, availability for on site installation directly ★ Improving on-site installation efficiency, substantially saving the cost of construction and installation
