The invention discloses a storing box for transferring photovoltaic assemblies. The storing box comprises a box body, the photovoltaic assemblies, roller shafts, rollers, a box door, hoops and pullingrods, wherein a plurality of layers of storing platforms which are uniformly distributed at intervals on the top and at the bottom are arranged at the inner side of the box body; the storing platformat each layer comprises a plurality of roller shafts which are distributed at intervals in the front and at the back; and the photovoltaic assemblies are arranged on the positioning platform at eachlayer. According to the storing box for transferring the photovoltaic assemblies, a first clamping block, a second clamping block, a movable clamping block and an adjustable moving plate are arrangedand used for clamping the photovoltaic assemblies, and a moving plate is synchronously adjusted to drive the movable clamping block to compress the photovoltaic assembly, thus the stability of the photovoltaic assemblies is ensured, and the photovoltaic assemblies are prevented from damage caused by shaking during transportation; and meanwhile, the rollers and the pulling rods are arranged on thebox body and facilitate moving and loading of the storing box; the pulling rods can be contracted and clamped through the hoops, so that the occupied area of the photovoltaic storing box can be reduced; and the transportation management is conveniently carried out.
