Disclosed is a solar panel being divided into a plurality of cells and including: a light transmissive power generation region which is a central region in a diameter direction of a ring-shaped member and in which extending thin line power generators are arranged in parallel in a direction substantially orthogonal to the extending direction; and a periphery power generation region which is a periphery region of the light transmissive power generation region and in which a part of the cells is arranged along a circumferential direction. The cells include a composite cell including at least a part of the periphery power generation region and at least a part of the light transmissive power generation region. A first cell and a second cell different from the first cell are respectively arranged on one end side and on the other end side in the diameter direction of the ring-shaped member.
