Circulation type space-based solar power system

A circulation type space-based solar power system, the system comprising:

• one or more solar modules;
• a body having at least two module attaching surfaces on which the solar modules are attached;
• a turning device whereby the module attaching surfaces loaded with the solar modules move between a solar power generating position and a recovery position by turning of the body, the solar modules of the module attaching surfaces receiving sunlight to generate solar power in the solar power generating position, and not receiving the sunlight in the recovery position;
• and
• an openable protective plate provided on each of the module attaching surfaces,
• wherein when the openable protective plate is closed, cosmic rays incident to the solar modules located in the recovery position are blocked by the openable protective plate, and when the openable protective plate is opened, the sunlight is incident to the solar modules located in the solar power generating position.
