📏 Specifications

ℹ️ Module Loading Considerations

• Semi-rigid and flexible panels can be walked on with anti-slip or flat soft sole shoes.
• Semi-rigid panels and flexible panels can support a concentrated weight (minimum area of 2” x 2”) of up to 180 pounds, with a rigid backing supporting the panel. Avoid sharp objects, chair legs, or high heels on panels — these can crack solar cells. Semi-rigid or flexible panels can support a distributed weight in excess of 180 pounds if the panel has a strong rigid backing.
• Placing heavy objects (such as installation tools) on the surface of the panel during or after installation of the panel is acceptable. Remove all obstructions once panels are installed.
• Do not walk on panels that are installed on uneven surfaces.
• Do not apply excessive loads on the corners of the panel.
