The 70MW distributed photovoltaic power generation project in the second phase of the industrial park is the largest distributed photovoltaic power generation project in Fujian Province.
After the full capacity grid connection of the project is put into operation, the average annual power generation for 25 years is 72198.8 MWh. Based on the average coal consumption of 305.5 g standard coal/kWh for power generation, 22056 tons of standard coal can be saved annually, reducing smoke and dust emissions by about 28.2 tons, reducing nitric oxide by about 506.8 tons, carbon dioxide by about 72786.8 tons, and sulfur dioxide by about 163.5 tons. The energy-saving benefits are obvious.
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.
