Storage bag and combined solar device

A combined solar device, comprising a bifacial solar panel and a storage bag, wherein

• the bifacial solar panel comprises a panel assembly and a support, an upper end of the support is connected to an upper side of the panel assembly, and a lower end of the support abuts against a second bag body;
• and
• the storage bag is used for storing the bifacial solar panel and comprises:
• a first bag body, wherein a first reflective layer is disposed on an inner side of the first bag body;
• and
• the second bag body connected to the first bag body, wherein a second reflective layer is disposed on an inner side of the second bag body, wherein
• the storage bag has a first state in which the bifacial solar panel is stored in the storage bag, and the storage bag has a second state in which the storage bag reflects sunlight to a back of the bifacial solar panel,
• wherein the first bag body is movably connected to the second bag body, the second bag body is laid flat, and the storage bag further comprises a position maintaining assembly for maintaining an included angle between the first bag body and the second bag body,
• wherein the position maintaining assembly comprises a first end and a second end that are opposite to each other, wherein the first end is connected to the first bag body, and the second end is connected to the bifacial solar panel,
• wherein a distance between the second end and the first end is adjustable,
• wherein the position maintaining assembly is configured to be a flexible structure and further comprises a body, wherein the first end and the second end are disposed at two opposite ends of the body, the second end is connectable to the body so that the second end and the body form an annular structure, the annular structure is configured to be sleeved on the bifacial solar panel, and a position where the second end is connected to the body is adjustable.
