1. Disadvantages of traditional power supply

      Solar power and solar power technology are increasingly entering the occasion of civilian applications. In communication or audio and video electronic equipment applications such as forests, roads, rivers, mountains, etc., grid power supply and battery power supply are mainly adopted. Battery power supply can often only solve temporary needs and cannot be used as a long-term power supply; instead, it adopts grid power supply. Many disadvantages:

　　A. The power supply method is cable transmission, which is difficult to construct and expensive;

　　B. The system is inconvenient to maintain, high-pressure transmission has potential safety hazards and high operating costs;

　　C. Difficulty in installation and networking.

　　2. Advantage of solar power supply

      The solar power supply system does not need water, oil, gas, or fuel when it works. It can generate electricity as long as there is light. It is a clean, pollution-free renewable energy source. It is simple to install and maintain, has a long service life, and can be unattended. Favored by people, it is the leader of new energy. In recent years, the application of solar energy has become more and more widespread in the world, especially in the field. Solar power systems are gradually replacing some traditional power equipment and are getting more and more common applications.
