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. A mounting-side engagement part of the mounting part is a notch that is provided in a lower end part and has a depth extending upward in the vertical direction. The support member is configured to support the solar cell module such that the locking part is inserted in the mounting-side engagement part and such that the solar cell module can be inclined with an inclination angle more than or equal to 10 degrees with respect to the support surface.
