Is intended to provide.

  In order to achieve this object, the present invention provides an anti-snow retaining member for attaching an anti-snow member that restricts snow falling on a solar panel on an inclined roof surface member to slide on the roof surface member. A mounting portion that is directly mounted on the roof surface member, and a snow stop support protrusion that is protruded to the same height as the solar cell panel so that the snow stop member disposed on the solar cell panel can be mounted and supported. It is characterized by providing.

  Moreover, the solar cell roof structure according to the present invention is provided with a solar cell panel having a panel support frame mounted around the solar cell panel body, and is provided on the upper surface portion of the roof surface member on which the solar cell panel is inclined. In addition, the above-described snow retaining member is directly attached to the roof surface member, and the snow retaining member that restricts the snow that accumulates on the solar cell panel from moving downward in the inclination direction of the roof surface member is the snow retaining member. It is attached to the member.

  According to this configuration, the snow retaining member can be easily attached onto the roof surface member in a state where the snow retaining member is disposed on the solar cell panel.
