Is the foldable solar panel soft or hard?

Soft board Traditional silicon-based solar panels are mostly hard silicon materials and cannot be folded and bent. Foldable solar panels are made of flexible materials, such as flexible and efficient thin-film solar cells and organic solar cells, which are flexible and foldable. The flexible characteristics of foldable solar panels make them more portable and easy to store when used outdoors, and can be unfolded to collect solar energy when needed, and can be folded compactly when not used, which is suitable for camping, traveling, outdoor adventure and emergency standby power supply.
