The green power project in Quangang District, Quanzhou City, which implements the national carbon peak and carbon neutrality strategic goal, has a total investment of 123 million yuan, a planned construction capacity of 21.05 megawatts, and a designed service life of 25 years.

After the project is completed, the average annual power generation can reach 21.98 million kilowatt hours. Calculated based on power generation and coal consumption, it can save 6700 tons of standard coal usage per year, reduce dust emissions by 1.98 tons per year, reduce carbon dioxide emissions by about 14000 tons, sulfur dioxide emissions by about 10.33 tons, and nitrogen oxide emissions by about 9.45 tons. This is of great significance for achieving environmental protection and promoting energy conservation and emission reduction in the Quangang area.

The project covers an area of 160000 square meters and has a maximum span of 50 meters. It adopts a new patented flexible support system, which solves the problem of traditional structural design not being able to achieve large spans. It is the first in the domestic petrochemical industry.

The sunlight shines on the semiconductor p-n junction, forming new hole electron pairs. Under the action of the built-in electric field in the p-n junction, holes flow from the n region to the p region, and electrons flow from the p region to the n region. After the circuit is connected, a current is formed.
