Abstract: An object of the present invention is to provide a manufacturing apparatus for a solar cell group that is likely to be recognized as having a good color balance when viewed by humans. The manufacturing apparatus for a solar cell group of the present invention includes an arrangement operation unit (12) that arranges solar cells and a machine learning unit (20). The solar cell group is formed by planarly arranging the solar cells. The solar cells have a light receiving surface and include an antireflection material on the light receiving surface side. Some of the solar cells have a variation in color element due to a difference in thickness of the antireflection material or a difference in refractive index of the antireflection material. The machine learning unit (20) performs machine learning using a correlation between an arrangement of the solar cells and a determination result by humans on color balance of the solar cell group as training data.

A value computed from a measured value of the color of reflected light combining positive reflected light and diffused reflected light which are based on light that has become incident on an object to be measured, and a measured value of the color only of the diffused reflected light based on the light that has become incident on the object to be measured, satisfies a specific condition.
