[0076] Please refer to Figure 9 , in some embodiments, the second overlapping base 520 further includes a sixth connecting plate 523. The sixth connecting plate 523 is connected to the side of the fifth connecting plate 522 away from the fourth connecting plate 521, and the sixth connecting plate 523 extends toward the side away from the second water storage tank 530; the sixth connecting plate 523 is spaced from the fourth connecting plate 521 along the second direction; the sixth connecting plate 523 and the fifth connecting plate 522 together form a second accommodating cavity 524; the fifth mounting profile 600 can be at least partially snap-connected into the second accommodating cavity 524 and is snap-connected to the sixth connecting plate 523. By providing the sixth connecting plate 523, the sixth connecting plate 523 and the fifth connecting plate 522 together enclose an open second accommodating cavity 524, so that the fifth mounting profile 600 can be snap-connected into the second accommodating cavity 524 as shown in Figure 8 , thus realizing the snap connection between the fourth mounting profile 500 and the fifth mounting profile 600.

[0077] Please refer to Figure 9 and Figure 10 , in some embodiments, one of the sixth connecting plate 523 and the fifth mounting profile 600 is configured with a third snap projection 525, and the other is configured with a third snap groove 620, and the third snap projection 525 cooperates with the third snap groove 620. By respectively providing the mutually cooperating third snap projection 525 and the third snap groove 620 on the sixth connecting plate 523 and the fifth mounting profile 600, the connection between the sixth connecting plate 523 and the fifth mounting profile 600 forms a self-locking structure through the cooperation of the groove and the projection, which is relatively stable. It should be noted that there is no special limitation on whether to provide the third snap projection 525 or the third snap groove 620 on the sixth connecting plate 523 and the fifth mounting profile 600, and it can be adaptively selected according to the actual situation. For example, it can be as shown in Figure 9As shown, a third clamping projection 525 is provided on the sixth connecting plate 523, and a third clamping groove 620 is also provided on the sixth connecting plate 523; as Figure 10 shown, a third clamping projection 525 is provided on the fifth mounting profile 600, and a third clamping groove 620 is also provided on the fifth mounting profile 600. Of course, only a clamping projection can be provided on one of the sixth connecting plate 523 and the fifth mounting profile 600, and only a clamping groove can be provided on the other.

[0078] Please refer to Figure 2 and combine with Figure 9 , in some embodiments, along the second direction, the height h3 of the first overlapping base 120 ( Figure 2 shown) is less than the height h4 of the second overlapping base 520 ( Figure 9 shown). By setting the height of the first overlapping base 120 to be less than the height of the second overlapping base 520, when the solar cell 700 is clamped in the Figure 11 shown frame, the first mounting profile 100 below the entire frame is lower, which is easy for the water on the surface of the solar cell 700 to flow into the first water storage tank 130 for convenient collection.

[0079] Please refer to Figure 9 and Figure 10 , in some embodiments, along the second direction, the height h5 of the second mounting base 510 ( Figure 9 shown) is less than the height h6 of the fifth mounting profile 600 ( Figure 10 shown). By setting the height of the second mounting base 510 to be less than the height of the fifth mounting profile 600, the water on the surface of the solar cell 700 can flow from the fifth mounting profile 600 to the fifth mounting profile 600 along the Figure 11 yy' direction in

[0080] Please refer to Figure 1 , Figure 4 and Figure 8 , the present application also provides a photovoltaic module, which includes the frame described in any one of the above embodiments, and further includes a solar cell 700; the frame is installed on the outer periphery of the solar cell 700, and can achieve at least one of the above technical effects.

[0081] Please refer to Figure 1 , Figure 4 and Figure 8, this application also provides a photovoltaic system, which includes the photovoltaic module described in any of the above embodiments, and multiple photovoltaic modules are arranged at intervals, and the frames of adjacent two photovoltaic modules are connected. By connecting the frames between multiple photovoltaic modules, a photovoltaic system with a larger size can be formed, thereby meeting different usage size requirements.

[0082] Multiple frames provided in the embodiments of this application are respectively installed on the outer periphery of multiple solar cells 700, thereby forming multiple photovoltaic modules, and the frames of multiple photovoltaic modules are overlapped with each other in the north-south direction of the xx' direction as shown in Figure 1 and Figure 11 and are closely matched with each other to form an integral drainage. When rainwater flows down from the high place x in the xx' direction of Figure 1 and Figure 11 , since the first water storage tank 130 of each photovoltaic module can store water, the possibility of water backflow at the profile lap joint is reduced after the rainwater accumulation at the bottommost photovoltaic module is too high.

[0083] Since the photovoltaic system has an installation inclination when installed, specifically, the installation inclination is the angle between the xx'yy' plane shown in Figure 11 and the horizontal plane. When the photovoltaic system composed of the frames provided in the embodiments of this application as shown in Figure 1 and Figure 4 is in use, the rainwater on each photovoltaic module flows along the inclined direction of the installation inclination, that is, the xx' direction in Figure 1 , from x to x'. After being stored in the first water storage tank 130, the flow rate is slowed down and then flows onto the next photovoltaic module, and flows in the above manner again, and finally flows to the gutter at the lowest x' place, thereby achieving the drainage effect of the photovoltaic module itself and forming a shingle effect.

[0084] When the photovoltaic system composed of the frames provided in the embodiments of this application as shown in Figure 1 , Figure 8 and Figure 11 is in use, the rainwater on each photovoltaic module flows along the inclined direction of the installation inclination, that is, the xx' direction in Figure 1 , from x to x'. When the rain is relatively heavy, there will be a certain amount of water stored on the surface of the solar cell 700. At this time, because the height of the fifth installation profile 600 is greater than the height of the second installation base 510 of the fourth installation profile 500, the water on the surface of the solar cell 700 will flow into the second water storage tank 530 of the fourth installation profile 500, and the water in the second water storage tank 530 flows along Figure 1 and Figure 11In the xx' direction, the water flows from x' towards x. The second water storage tank 530 communicates with the first water storage tank 130, and the water finally flows into the first water storage tank 130. When the height of the water is higher than the depth of the first water storage tank 130, the water flows through the second installation profile 200 of the next photovoltaic module and flows in the above manner on the next photovoltaic module, and finally flows to the gutter edge at the lowest x', thereby achieving the drainage effect of the photovoltaic module itself and forming a shingle effect.

[0085] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0086] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
