To provide a sprinkling system for a solar cell panel having excellent durability, and a sprinkling roof tile for use in the same.

A sprinkling roof tile 10 comprises a sprinkling nozzle 13 which sprinkles water toward a solar cell panel 3, a water supply pipe 11 which is connected to the sprinkle nozzle 13, and a body member 12 which is installed on a roof. The body member 12 includes a through-hole 121 which is bent at a midway part. The through-hole 12 includes a first opening 121a facing the solar cell panel 3 and a second opening 121b facing downward. The sprinkling nozzle 13 is accommodated in the through-hole 121 such that a nozzle face 13a is exposed from the first opening 121a. The water supply pipe 11 is accommodated in the through-hole 121, extending outward of the body member 12 through the second opening 121b. The body member 12 has a planar contour shape substantially equal to the shape a roof tile 25, allowing to be installed on a roof as replacement for the roof tile 25.
