The operating temperature of the Bifacial Solar Panel is -20°C–85°C (-4°F–185°F). The panel should be folded into its original shape and stored in its Protective Case (Kickstand), which provides sufficient protection for the product. To extend the service life of the panel, ensure that the product is not exposed to external forces/impacts when not in use. The solar panel itself is made of glass and must not be dropped, pierced, bent, or sat on. These actions may break the glass and render the panel unusable. Any such damage will not be covered by the free warranty.
