As is well known, China is a developing country and also a resource consuming country, with relatively low per capita resource reserves. Therefore, the rapid industrialization process and huge consumer demand have made China highly dependent on external resources. Environmental pollution and energy shortage have directly threatened China's sustainable development. At the same time, many people living in remote areas of our country have not yet had access to electricity. These objective conditions force us to work harder to find and develop new energy, and solar photovoltaic power generation is one of them.

After entering the 1970s, due to the impact of the second oil crisis, people objectively realized that the existing energy structure must be completely changed and the transition to the future energy structure should be accelerated. As a result, many countries, especially industrialized nations, have strengthened their support for the development of solar energy and other renewable energy technologies.

The advantages of photovoltaic power generation are fully reflected in the following aspects:

1. Solar energy resources are inexhaustible and inexhaustible. The solar energy shining on the Earth is 6000 times greater than the energy currently consumed by humans. Furthermore, based on the nuclear energy generated by the sun, it is estimated that the sun will illuminate the Earth for over 60 billion years.

2. Green and environmentally friendly. Photovoltaic power generation itself does not require fuel, does not emit carbon dioxide, does not pollute the air, and does not produce noise.

3. Wide range of applications. Photovoltaic power generation systems can be used wherever there is light.

4. Long service life, simple maintenance, and high reliability. Crystalline silicon solar cells have a lifespan of up to 20-35 years; Due to the absence of mechanical rotating parts, operation and maintenance are simple, and reliability is high. In addition, automatic control technology is now used, which basically does not require manual operation.

5. Solar cell modules have a simple structure, small and light size, are easy to transport and install, have a short construction period for photovoltaic power generation systems, and are easy to combine.
