The head of the bolt can press against the end face of the purlin 6 away from the water guide channel 5, thereby pressing the photovoltaic module frame 7 and the water guide channel 5 against the purlin 6. It is understood that fastener 4 can also be other types of structures, as long as it meets the above functions.

The window structure 11 is located in the vertical direction (see attached diagram).
