Referring to fig. 1, a schematic structural diagram of a photovoltaic system according to an embodiment of the present application is shown; referring to fig. 2, an enlarged schematic view of portion a of fig. 1 is shown. As shown in fig. 1, the photovoltaic system has a first direction x and a second direction y perpendicular to each other, wherein the first direction x is a direction indicated by an arrow x in fig. 1, and the second direction y is a direction indicated by an arrow y in fig. 1. The photovoltaic system may specifically include: support cable assembly 10, support assembly 20, and photovoltaic assembly 30; the supporting component 20 comprises two side plates 21 and a bottom plate 22 which are arranged along a first direction x, wherein the two side plates 21 and the bottom plate 22 are fixedly connected in pairs to form a triangular shape, and the bottom plate 22 is attached to the ground; the multiple groups of support assemblies 20 are arranged at intervals along the second direction y; the second direction y is perpendicular to the first direction x; the supporting cable assembly 10 is arranged along the second direction y and connected to a plurality of groups of supporting assemblies 20; the photovoltaic module 30 is connected to the support cable assembly 10.

In the embodiment of the present application, the supporting component 20 is disposed along the first direction x and is attached to the ground of the installation area of the photovoltaic system for placement, so as to provide basic support for the supporting cable component 10; the support cable assembly 10 is disposed along the second direction y and connected to the top of the support assembly 20; the photovoltaic module 30 is connected to the support cable module 10.

Specifically, the supporting component 20 includes two side plates 21 and a bottom plate 22, the length directions of the two side plates 21 and the bottom plate 22 are set along the north-south direction, the long sides of the two side plates 21 and the bottom plate 22 are fixedly connected in pairs and are enclosed into a triangular shape, wherein the bottom plate 22 is attached to the ground of the installation area of the photovoltaic system to be placed, the connection position of the two side plates 21 forms the top of the supporting component 20, and the supporting cable component 10 is set along the east-west direction and is connected to the top of the supporting component 20.
