Abstract: A photovoltaic module support, a photovoltaic module supporting assembly and a photovoltaic power station are provided. The photovoltaic module support is a structural member formed by stamping and bending, and comprises a support body which is provided with a reinforcing groove, and/or a reinforcing protrusion, and/or a turning edge. The photovoltaic module support is the structural member formed by stamping and bending, and a raw material thereof is a metal plate or a metal coiled material, such that the material cost and the processing cost are effectively reduced in comparison with existing structural members made by cutting an aluminum profile, thereby reducing the cost of the whole photovoltaic module support.
