Claim 0:
1. A corner piece for palletization of solar cell panels, the corner piece comprising:
a right-angled corner part configured to cover a right-angled corner of a frame of a solar cell panel;
a support piece enabling the frame to be laid thereon, at a corner of a bottom surface of an inner side of the right-angled corner part;
a pressing piece extending inward from a top of the right-angled corner part in an integrated manner so as to press a top of the frame, and provided with a first locking protrusion placed at a lower side of a pressing piece distal end of the pressing piece so as to be locked to an inner side of the frame, wherein the inner side of the frame extends between the top and a bottom of the frame;
a fixing protrusion part protruding upward from the top of the right-angled corner part; and
a concave hole formed in a lower surface of the right-angled corner part and enabling the fixing protrusion part formed on the top of the right-angled corner part of another corner piece to be inserted into the concave hole for combination of the corner pieces,
wherein when stacking a solar cell panel which has a frame fabricated with two types of sides differing in width, in order to be locked to the inner side of the frame regardless of the two types of sides of the frame differing in width, the lower side of the pressing piece having the first locking protrusion at the pressing piece distal end is also provided with a second locking protrusion configured for being engaged and locked to the inner side of the frame having a narrow one of the different widths; and
the second locking protrusion is formed at a lower side of a tension piece and depends downwardly substantially at a right angle from the lower side of the tension piece, wherein the tension piece is elastic, wherein the tension piece has a proximal end and a tension piece distal end and side ends between the proximal end and the tension piece distal end, wherein the proximal end is attached to the pressing piece, wherein the tension piece distal end and side ends are spaced from the pressing piece to define a gap located between the pressing piece and the tension piece distal end and the side ends of the tension piece, wherein the gap and the tension piece are configured to enable the tension piece to bend upwardly relative to the pressing piece so that when the first locking protrusion formed at the distal end of the lower side of the pressing piece is locked to the inner side of the frame, the tension piece is bent by the tension force to allow the pressing piece to be in contact with a top of the frame without being disturbed by the second locking protrusion placed at the lower side of the pressing piece.
