[0002] Photovoltaic power generation is a kind of technology that utilizes the photovoltaic effect of semiconductor interface to convert light energy into electric energy directly. It is mainly composed of solar panel (component), controller and inverter three parts, and main components are composed of electronic components. Solar cell is encapsulated after series connection to form large-area solar cell component, and then cooperate with power controller and other components to form photovoltaic power generation device.

[0003] The height of the existing guardrail is fixed. For example, the common metal guardrail, the vertical column and the horizontal rod are fixedly connected by welding or riveting, forming a unified height specification, and once the installation is completed, the height cannot be adjusted. The design of fixed height exposes obvious defects when facing different construction environments: in some photovoltaic power stations near residential areas or roads, the guardrail near the area with frequent human activities needs higher height to prevent unauthorized personnel from climbing over to avoid electric shock and other safety accidents, and in relatively remote areas with few personnel, there is no need for too high guardrail, and appropriately reducing the height can save material cost and facilitate daily inspection and maintenance. However, the existing fixed-height guardrail cannot flexibly adapt to the differentiated requirements of different areas for the height of the guardrail, which greatly reduces its practicability in actual use and makes it difficult to meet the complex and changeable construction and operation requirements of photovoltaic power stations.
