Solar energy is a natural resource. The system that collects and converts solar energy to turn it into controllable electrical energy is called solar photovoltaic power generation system. This technology was successfully studied by Bell Labs in the United States in the early 1950s. Only used in high-tech fields such as aerospace. The global energy crisis that broke out in the 1970s prompted the rapid promotion of this technology to civilian use. After more than 30 years of continuous improvement and development, a complete and mature technology has been formed. With the implementation of the global sustainable development strategy, the technology has received strong support from many governments. It is currently in the United States, Europe, and Japan. When developed countries have achieved universal application, they have also been widely used in economically developed coastal areas in China.

With the rapid development of the solar energy industry today, photovoltaic systems have the following advantages and characteristics compared with Changgui Energy:

Clean and efficient renewable energy (using the solar energy provided by nature for free)

Energy saving: does not consume conventional energy.

Environmental protection: no pollution to the environment.

Installation is simple, no cables are required.

One-time investment will benefit for life.
