Application scenarios of solar power supply system in power communication

1) Power supply guarantee for communication base stations in remote areas
In many remote areas, city electricity is often difficult to reach or the supply is extremely unstable, and the solar power supply system has played a huge advantage here, becoming a key force to ensure the stable operation of communication base stations.

For example, in high-altitude and cold areas such as southern Xinjiang and northern Tibet in China, there are many problems such as no city electricity, low temperature, and poor infrastructure. An off-grid solar power generation system consisting of high-efficiency monocrystalline silicon solar cells and valve-controlled sealed lead-carbon batteries can be used to provide reliable power for 5G base stations. In this case, the photovoltaic panels in the solar power supply system can fully absorb solar energy and convert it into electrical energy, and can operate stably even in a high-altitude and cold environment; the battery can release the stored electrical energy when there is insufficient sunlight, such as on cloudy days or at night, to ensure that the base station equipment continues to obtain power support, thereby ensuring the normal transmission of communication signals and meeting the communication requirements of local businesses such as edge computing, 4K ultra-high-definition real-time video, and telemedicine.

In short, the solar power supply system has shown strong adaptability and reliability in powering communication base stations in remote areas, laying a solid foundation for the development of the communication industry in these areas.

2) New energy-saving options for communication terminals
Communication terminals usually have the characteristics of high energy consumption costs and large power loads, and the application of solar power supply systems has brought new energy-saving ideas and significant benefits.

On the one hand, the solar power supply system can effectively reduce the consumption of city electricity. The roof space of the computer room of the communication terminal is often sufficient, and a large number of solar panels can be installed in a centralized manner, and the comprehensive construction cost is lower than that of the communication base station. For example, Shangqiu Unicom conducted a photovoltaic power generation pilot in a certain terminal, directly introducing photovoltaic power generation into the original communication DC power supply system of the terminal, making full use of solar energy resources, converting light energy into electrical energy for the communication terminal, which significantly reduced the use of city electricity and alleviated the pressure of energy consumption.

On the other hand, the application of solar power supply systems in communication terminals has brought considerable economic and social benefits. From the perspective of economic benefits, as the photovoltaic industry technology becomes more mature, the prices of photovoltaic modules and their supporting equipment are gradually reduced. The application of solar power supply systems in communication terminals can not only reduce electricity costs, but also obtain investment returns on power generation in the long run. From the perspective of social benefits, the use of solar energy as a clean energy can reduce dependence on traditional fossil energy, reduce carbon emissions, meet the current environmental protection concepts and requirements such as carbon peak, and help the sustainable development of society.

Previously, the Xilanwu and Lanxila optical cables built in the 1990s also used photovoltaic power generation systems as the main power supply, solving the power supply problem of unmanned relay stations in high-altitude and desert areas, and providing a good practical reference and experience for the application of solar power supply systems in today's communication terminals. It can be seen that the application of solar power supply systems in communication terminals is a high-quality choice that takes into account energy saving, economic and social benefits, and has broad development prospects.
