Wherein, the flow guide opening 340 is arranged at the lower end of the auxiliary groove 330, so that a small amount of water seeping from the auxiliary hole 440 can be drained to the adjacent lower photovoltaic tile for drainage. Wherein, the auxiliary hole 440 is located at the lower end of the tile body 100.

[0084] Referring to Figure 3 , Figure 4 is a side view of the photovoltaic tile provided in one embodiment of the utility model. In another embodiment, the connecting part 600 is detachably connected to the connecting protrusion 630 arranged on the tile body 100.

[0085] Specifically, the tile body 100 is provided with the connecting protrusion 630, the connecting protrusion 630 is an integral structure with the tile body 100, and the connecting part 600 is connected to the connecting protrusion 630 in a manner that the connecting part 600 is stably connected to the tile body 100 while the waterproof performance of the tile body 100 is ensured, and water leakage of the tile body 100 is prevented.
