    Abstract: According to one embodiment, a solar cell module includes a solar cell panel and a concentrator. The solar cell panel includes a solar cell. The concentrator reflects light incident from the outside and irradiates the light onto the solar cell. The concentrator has a first surface and a second surface. The first surface reflects light incident at a first incident angle and irradiates the light incident at the first incident angle onto a first portion within the area of the solar cell. The second surface reflects light incident at a second incident angle and irradiates the light incident at the second incident angle onto a second portion within the area of the solar cell. The second incident angle is different from the first incident angle. The second portion is different from the first portion. The first surface and the second surface are asymmetric as viewed from the solar cell.
