The utility model discloses a solar module's packing plant, including packing box and a plurality of plastic steel areas, a plurality of even pre -buried the fixing in the packing box of length direction that the back -porch packing box was handled through buckling in the plastic steel area for solar module to placing in the packing box fastens, every plastic steel area position of buckling in the packing box is located the long limit of box and box top surface and cabinet bottom surface's juncture, and the both ends in every plastic steel area are the free end. Owing to pre -buriedly in the packing box be fixed with a plurality of plastic steel areas after handling through buckling, therefore can realize that it fastens through the plastic steel area solar module in to the packing box to accomplish the vanning back at solar module to make all solar module in the packing box form as one, the inside of having avoided solar module to produce is in transit effectively concealed and is split.
