1) Expansion opportunities brought by technological progress
With the continuous development of photovoltaic industry technology, solar power supply systems are facing unprecedented expansion opportunities in the field of power communications. In terms of efficiency improvement, the photoelectric conversion efficiency of photovoltaic panels has been significantly improved. For example, the photoelectric conversion efficiency of monocrystalline silicon photovoltaic panels can reach about 24% at most, and is still moving towards a higher level. At the same time, new photovoltaic materials and battery structures are constantly emerging. Materials such as perovskite have shown excellent photoelectric performance in the laboratory stage, which is expected to further improve the efficiency of converting solar energy into electrical energy, so that under the same lighting conditions, more electricity can be generated to meet the power demand of power communication equipment.

In terms of the reduction of supporting equipment costs, the prices of photovoltaic modules and related supporting equipment are gradually decreasing. In the past, the high equipment costs made many communication operators have concerns about the large-scale application of solar power supply systems, but now the situation has changed greatly. Taking the communication terminal as an example, as the cost decreases, its comprehensive construction cost is lower than that of the communication base station, and the roof space of the computer room is often sufficient, and a large number of solar panels can be installed in a centralized manner, which makes the application of solar power supply systems in communication terminals more economical and feasible.

In addition, energy storage technology has also made great progress. The energy density of batteries has been continuously increased, the charging and discharging efficiency has been improved, the service life has been extended, and the cost has been reduced. This means that in the power communication system, even if there is insufficient light such as continuous cloudy days, the battery can better store electricity and continuously and stably supply power to the communication equipment. The functions of intelligent controllers are also becoming more powerful. They can not only adjust the distribution and storage of electricity more accurately, but also realize complex functions such as remote monitoring and fault warning, and fully guarantee the stable operation of the system.

These technological advances have combined to expand the application scope of solar power supply systems in the field of power communication. Whether it is communication base stations in remote areas, communication terminals with large power loads, or even more communication scenarios in the future, they can play a better role and provide strong power support for the stable development of the communication industry.

II) Effective means to cope with energy consumption pressure in the communication industry
At present, the communication industry is facing severe challenges of energy consumption pressure, especially with the rapid development of 5G network construction, this problem has become more prominent. According to relevant data, in the past year since 5G was put into commercial use, the power consumption of my country's communication network has increased by 14.6%, and the total energy consumption of 5G may be about 4-9 times that of 4G. Communication operators are in urgent need of finding effective solutions to reduce energy consumption and improve their operating capabilities.

Solar power supply system has become an effective means to cope with this energy consumption pressure by virtue of its many advantages. First of all, as a clean energy, solar energy is inexhaustible. In the process of converting solar energy into electricity and applying it to power communication, it will not produce greenhouse gases such as carbon dioxide like traditional fossil fuel power generation, nor will it emit harmful substances such as dust and waste residue, which reduces the impact on the environment from the root, conforms to the current environmental protection concepts and requirements such as carbon peak and carbon neutrality, helps the communication industry to transform towards a green and low-carbon direction, and is also in line with the general trend of global sustainable development.

Secondly, the solar power supply system can significantly reduce the dependence of the communication industry on the mains and reduce the consumption of mains. For example, Shangqiu Unicom conducted a pilot project of photovoltaic power generation in a certain terminal office, directly introducing photovoltaic power generation into the original communication DC power supply system of the terminal office, making full use of solar energy resources, converting light energy into electrical energy for use by the communication terminal office, which significantly reduced the use of city electricity and alleviated the pressure of energy consumption. In the long run, with the cost reduction brought about by the maturity of photovoltaic industry technology, the application of solar power supply system can not only reduce electricity costs, but also obtain investment returns on power generation in the long run, which is also a great benefit to operators from the perspective of economic benefits.
