The principle of solar photovoltaic system power generation: the sun shines on the semiconductor p-n junction, forming a new hole electron pair. Under the effect of the electric field of the p-n junction, holes flow from the n-area to the p-area, and electrons flow from the p-area to the n-area. After the circuit is connected, a current is formed. This is the working principle of photoelectric effect solar cells.

With the increasing variety of solar cells, the use scale of solar photovoltaic system is increasingly broad, and the market scale is gradually expanding. In the early stage, the use of solar energy was mainly used in military and aerospace fields. Now, solar energy has entered industry, commerce, agriculture, communication, household appliances and public facilities. The use of solar power generation can be divided into several aspects: small household solar power plants, large grid connected power plants, building integrated photovoltaic glass curtain walls, solar street lamps, landscape complementary street lamps, landscape complementary power supply system, etc., such as solar garden lamps; Solar photovoltaic system power generation user system; In particular, the independent system of village power supply can be used in remote areas, mountains, deserts, islands and villages to save expensive transmission lines; There are also photovoltaic water pumps (drinking water or irrigation); Communication power supply; Cathodic protection of oil pipeline; Power supply for optical cable communication station; Seawater desalination system; Road sign in town; Highway road signs, etc.

The following aspects must be improved for the solar photovoltaic system:

1. Increase production scale, improve technical level and product quality;

2. Improve the conversion of solar photovoltaic power and reduce the production cost of products;

3. Truly complete the grid connected operation of solar power generation and the existing power grid. It is the strategic requirement of China's future power development to vigorously develop new power. Because of the increasing tension of power and the continuous development of photovoltaic technology, the development and use of solar energy will be the scientific and technological development direction of human new power use. As long as we rely on more advanced science and technology, it is possible to use solar energy on a large scale to pioneer a broad prospect for mankind in the future.
