The optical reflection of the module changes depending on the material of the front protection of the cell (glass, plastic) or any processing of the glass. For the manufacturer is very important to minimize the optical reflection in order to capture the maximum solar radiation.
Each photovoltaic module reflects light differently. Some of them do not reflect the image, while others reflect the shape even if not clearly visible, still others reflect the image as a mirror.

The reflection is also a function of the angle of incidence. For a glass has the following curve.
