Solar cell module

A solar cell module that holds a solar cell panel using a plurality of pairs of members, each pair constituted from a main frame member that holds one side of the solar cell panel and a sub-frame member that holds an adjoining side that adjoins the one side, wherein

• the main frame member is formed comprising a main outer wall that is formed along one side of the solar cell panel, a main holding upper piece and a main holding lower piece that are provided projecting inward, above and below, to an inner side of an upper part of the main outer wall, and hold the solar cell panel fitted therebetween, and a main bottom piece that is formed on an inner side of the main outer wall below the main holding lower piece along the main outer wall, projecting further inward than the main holding upper piece and the main holding lower piece,
• the sub-frame member is formed comprising a sub-outer wall that is formed along the adjoining side of the solar cell panel, a sub-holding upper piece and a sub-holding lower piece that are provided projecting inward, above and below, to an inner side of an upper part of the sub-outer wall, and hold the solar cell panel fitted therebetween, and a sub-bottom piece that is formed on an inner side of the sub-outer wall below the sub-holding lower piece along the sub-outer wall, projecting further inward than the sub-holding upper piece and the sub-holding lower piece,
• in the main outer wall of the main frame member, the main holding upper piece and the main holding lower piece are spaced from an end edge of the main outer wall, for substantially a same width as a projecting length of the sub-holding upper piece and the sub-holding lower piece of the sub-frame member along a length direction of the main outer wall, a flat main outer wall edge portion inner side surface is provided on an inner side of an edge portion of the main outer wall, and an end surface of each edge portion of the sub-outer wall, the sub-holding upper piece, the sub-holding lower piece and the sub-bottom piece of the sub-frame member is abutted against the main outer wall edge portion inner side surface, connecting the main frame member and the sub-frame member, and
• the main bottom piece and the sub-bottom piece extend substantially along a length of the main outer wall and the sub-outer wall, respectively, and are formed so as not to collide with each other, such that projecting position heights of the main bottom piece and the sub-bottom piece are different.

A solar cell module that holds a solar cell panel using a plurality of pairs of members, each pair constituted from a main frame member that holds one side of the solar cell panel and a sub-frame member that holds an adjoining side that adjoins the one side, wherein

• the main frame member is formed comprising a main outer wall that is formed along one side of the solar cell panel, a main holding upper piece and a main holding lower piece that are provided projecting inward, above and below, to an inner side of an upper part of the main outer wall, and hold the solar cell panel fitted therebetween, a main base piece that is formed projecting inward on an inner side of a lower edge of the main outer wall along the main outer wall, a main inner wall that is formed parallel to the main outer wall connecting the main base piece and the main holding lower piece, and a main bottom piece that is formed on an inner side of a lower edge of the main inner wall along the main inner wall, projecting further inward than the main holding upper piece and the main holding lower piece,
• the sub-frame member is formed comprising a sub-outer wall that is formed along the adjoining side of the solar cell panel, a sub-holding upper piece and a sub-holding lower piece that are provided projecting inward, above and below, to an inner side of an upper part of the sub-outer wall, and hold the solar cell panel fitted therebetween, a sub-base piece that is formed projecting inward on an inner side of a lower edge of the sub-outer wall along the sub-outer wall, a sub-inner wall that is formed parallel to the sub-outer wall connecting the sub-base piece and the sub-holding lower piece, and a sub-bottom piece that is formed on an inner side of the sub-inner wall along the sub-inner wall, projecting further inward than the sub-holding upper piece and the sub-holding lower piece,
• the solar cell module is fixed using the main bottom piece when installed,
• in the main outer wall of the main frame member, the main holding upper piece, the main holding lower piece, the main inner wall, the main base piece, and the main bottom piece are spaced from an end edge of the main outer wall, for substantially a same width as a projecting length of the sub-holding upper piece and the sub-holding lower piece of the sub-frame member along a length direction of the main outer wall, a flat main outer wall edge portion inner side surface is provided on an inner side of an the edge portion of the main outer wall, an end surface of each edge portion of sub-outer wall, the sub-holding upper piece, the sub-holding lower piece, the sub-base piece and the sub-inner wall of the sub-frame member is abutted against the main outer wall edge portion inner side surface, an end surface of edge portion of the sub-bottom piece is abutted against an inner side surface of the main outer wall except for the main outer wall edge portion inner side surface, connecting the main frame member and the sub-frame member,
• the sub-bottom piece of the sub-frame member is formed projecting on the inner side of the sub-inner wall, so as to be positioned above the main bottom piece of the main frame member, and
• in the main inner wall, a slit that has an open end and has a same length as a projecting length of the sub-bottom piece is formed, in a same height position as a projecting position of the sub-bottom piece, and when the main frame member and the sub-frame member are connected, the sub-bottom piece is inserted in the slit.
