Renewable Energy From Floating Solar Panels
Avient worked with a progressive customer who designed floating solar panels that float on large bodies of water, and require very demanding weather resistance in harsh environments.
Existing industry solutions failed to protect panels from outdoor exposure and harsh weather conditions.

This coordinated effort resulted in the innovative Modular Protective System (MPS) portable structure, which incorporates an Edwards-designed collapsible truss framework and Avient’s GlasArmor™ ballistic-resistant composite panels.
GlasArmor panels made with fiber-reinforced polymer (FRP) composites provide excellent ballistic stopping power for the MPS while meeting the requirement of being lightweight and portable.
The MPS incorporates Avient’s custom-formulated GlasArmor ballistic panels that meet Level 3 protection under Underwriters Laboratories (UL) 752 standards for ballistic resistance.
