Abstract: The present invention provides a solar cell module installation structure that can be installed on a wall surface of a building, and provides a house and a solar cell module. A support member has a support surface that spreads out substantially in a vertical direction. A locking piece of the support member has: a locking part that faces the support surface at an interval and extends upward; and a connection part that connect the locking part and the support surface. A frame member of the solar cell module has: a holding recess that sandwiches a part of a main body panel of the solar cell module and is in contact with a light receiving surface and a back surface of the main body panel; and a mounting part that is provided on a back surface side of the main body panel, has higher rigidity than the main body panel, has a length longer than or equal to ½ of one side of the main body panel, and extends in the vertical direction.

Abstract: The present invention provides a solar cell module installation structure and a house that can reduce manufacturing cost and have good workability as compared with the related art. A support member includes a rail part that extends substantially in a vertical direction and is longer than a length of the solar cell module. The solar cell module includes: a solar cell panel; and a frame member. The solar cell panel includes: a main body panel; a terminal box provided on a back surface of the main body panel; and a wiring part extending from the terminal box. The frame member includes: a holding recess; and a mounting part. The holding recess sandwiches a part of the main body panel and is in contact with a light receiving surface and the back surface of the main body panel. The mounting part is provided on a back surface of the main body panel and is attached to the rail part of the support member.

Abstract: First and second engaging members (15) each including an engaging portion (15n) are attached to a ridge-side end of each of first through third solar cell panels (11) and are disposed with an interval in a beam direction. First and second engaged members (21) each including an engaged portion (21i) are attached to an eaves-side end of each solar cell panel (11) and are disposed with an interval in the beam direction. The engaging portion (15n) of the first engaging member (15) of the first solar cell panel (11) is engaged with the engaged portion (21i) of the first engaged member (21) of the second solar cell panel (11), whereas the engaging portion (15n) of the second engaging member (15) of the first solar cell panel (11) is engaged with the engaged portion (21i) of the second engaged member (21) of the third solar cell panel (11).

Abstract: In an optical receiver, a control unit determines an SOA current set value such that an SOA current becomes a maximum value ISOA_MAXwhen a VOA voltage is smaller than a first threshold value VVOA_LOW, determines the SOA current set value such that the SOA current becomes smaller than the maximum value ISOA_MAX and larger than a minimum value ISOA_MIN when the VOA voltage is equal to or larger than the first threshold value VVOA_LOW and is smaller than a second threshold value VVOA_HIGH, and determines the SOA current set value such that the SOA current is fixed to the minimum value ISOA_MIN when the VOA voltage is equal to or larger than the second threshold value VVOA_HIGH.
