[0002] Photovoltaic, or photovoltaic power generation system, is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. With the development of new energy technology and the country's emphasis on new energy, the application of photovoltaic power generation in the distributed field has grown rapidly. For example, distributed photovoltaic power generation projects have grown rapidly in counties. Such projects follow the principles of adapting measures to local conditions, clean and efficient, decentralized layout, and nearby utilization, effectively increasing the power generation of photovoltaic power stations of the same size and solving the problem of power loss in boosting and long-distance transportation.

[0003] Based on the above, the inventors have discovered the following problems: photovoltaic power supply is widely used on the roofs of rural and urban buildings, but when adding photovoltaics to already built houses, due to the different styles of house buildings, some roofs have larger slopes, and some roofs are flat. Therefore, when adding photovoltaics to existing roofs, different styles of components are needed to install photovoltaic panels, and the widths of photovoltaic panels are also different, which greatly increases the difficulty of adding photovoltaics.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a node structure for adding photovoltaics to the existing roof is provided, in order to achieve a more practical purpose. Utility Model Content

[0015] Furthermore, a servo motor is fixedly mounted on one side of the connecting rod, and an output end of the servo motor is transmission-connected to the mounting plate.

[0016] The beneficial effect of adopting the above further solution is that by installing a servo motor, the servo motor can drive the mounting plate to rotate when it is working, thereby adjusting the angle of the photovoltaic panel to adapt to the slope of the existing roof.
