Solar photovoltaic module mounting structure for roof

The utility model relates to the technical field of solar energy installation. The utility model further discloses a solar photovoltaic module mounting structure for the roof. The device comprises a photovoltaic module, a stretching device and a supporting device, the lower end of the photovoltaic module is fixedly connected with a stretching device, a supporting device is fixedly installed at thelower end of the stretching device, a roller is arranged at the lower left end of the solar panel, shaft rods are movably installed on the two sides of the roller, a clamping groove is formed in thesurface of the lower end of the solar panel, and a rectangular block is arranged at the bottom of the solar panel. The solar photovoltaic module mounting structure for the roof is simple in structure;in hot weather, water in the sponge pipe is absorbed by the sponge block in the rectangular block; the small holes can allow outside air to enter, then moisture in the sponge block is evaporated, surrounding heat is absorbed,
