Solar cell module

A solar cell module, comprising:

• a solar cell panel including a solar cell;
• and
• a concentrator reflecting light incident from the outside and irradiating the light onto the solar cell,
• the concentrator having
• a first surface reflecting light incident at a first incident angle and irradiating the light incident at the first incident angle onto a first portion within the area of the solar cell, and
• a second surface reflecting light incident at a second incident angle and irradiating the light incident at the second incident angle onto a second portion within the area of the solar cell, the second incident angle being different from the first incident angle, the second portion being different from the first portion,
• the first surface and the second surface being asymmetric as viewed from the solar cell,
• wherein the solar cell panel is located at an opposite back side of the concentrator to an incident side of the concentrator, the incident side being an entire front surface of the concentrator that receives incident light.
