A holding frame includes a main frame member extending along a first side of the light-receiving surface, and a sub-frame member extending along a second side adjacent to the first side, wherein the main frame member includes a main outer wall extending along the first side, main holding units formed on the main outer wall to hold the solar cell panel from the first-side side, and a main bottom piece formed on the main outer wall protruding towards inside of the holding frame. The sub-frame member includes a sub-outer wall extending along the second side, sub-holding units formed on the sub-outer wall to hold the solar cell panel from the second-side side, and a cylindrical part formed to include the sub-outer wall, extending along the second side on the back surface side of the solar cell panel. |

1. A holding frame surrounding the periphery of a solar cell panel that has a light-receiving surface of a substantially rectangular shape, the holding frame comprising:
a main frame member that is provided to extend along each of first sides facing each other out of all sides constituting the light-receiving surface; and a sub-frame member that is provided to extend along second sides, each being adjacent respectively to the first sides and facing each other, wherein the main frame member includes a main outer wall that is formed to be upright in a substantially vertical manner to the light-receiving surface and is formed to extend along the first side, a main holding unit that is formed on the main outer wall and holds the solar cell panel from the first-side side, and a main bottom piece that is formed on the main outer wall and protrudes towards inside of the holding frame on the back surface side of the light-receiving surface, the sub-frame member includes a sub-outer wall that is formed to be upright in a substantially vertical manner to the light-receiving surface and is formed to extend along the second side, a sub-holding unit that is formed on the sub-outer wall and holds the solar cell panel from the second-side side, and a cylindrical part that is formed to include the sub-outer wall and extends along the second side on the back surface side of the solar cell panel, the sub-frame member is coupled to the main frame member by abutting an end of the cylindrical part against an inner surface of the main outer wall, and a notch that is bored through the main outer wall from the outer-side surface to the inner-side surface and allows the outside of the holding frame to communicate with the inside of the cylindrical part is formed on the main outer wall. |
