A photovoltaic module has a reinforcement beam for strength reinforcement. The photovoltaic module includes a solar panel having one or more solar cells, a frame surrounding an edge of the solar panel, and a reinforcement beam connecting two separate sides of the frame at the rear of the solar panel, which is opposite to a light receiving surface of the solar panel upon which solar light is incident, the reinforcement beam having a hollow space defined therein.
