10,000 to 20,000 square meters.
Photovoltaic power generation is a power generation method that uses the solar photoelectric effect to directly convert solar radiation energy into electrical energy. The capacity of photovoltaic power plants is generally measured in megawatts (MW). Due to the different structures and material properties of photovoltaic panels, the required floor area per unit capacity of different types of photovoltaic power plants will also be different.
A one-megawatt photovoltaic plant requires an area of approximately 10,000 to 20,000 square meters. This area is linked to many factors, such as the intensity of solar radiation, the efficiency of photovoltaic panels, the layout of power plants, etc.
10,000 square meters, the annual electricity production is 1,708,900 kilowatt hours and the electricity productionAverage daily rate is 349 kilowatt hours.
Generally, the area of a 250w photovoltaic solar panel is 1.65×0.992=1.6368m?, or 250÷1.6368=152.73w/m?, and 1 mu of land converted into meters is 666.67m? , 300×666.67=200001m?, if it is tiled, it is:
200001×152.73=30546152.73w Of course, it is impossible to install it tiled, and 20 %. maintenance space needs to be reserved, then it is 200001×152.73×0.8÷1000=24436.92218kw If calculated based on the sunshine time in the northwest desert area, there can be have on average 6 hours of effective sunshine per day.
The annual electricity production is approximately 24436×6×365=53514840 kilowatt hours of electricity. At the parity rate of 0.48, the annual income is: 53514840×0.48=25687123.2 yuan.
The cost of photovoltaic construction is about 3 yuan/w, which requires an investment of 24436922×3=73310766 yuan. If the operating costtation is not included, the cost can be recovered in 3 to 4 years. Of course, the operating cost cannot be ignored. In fact, it is almost 10. The cost can only be recovered in 10 years, and the net profit will be 20 million yuan/year in the next 10 years.
This is only theoretical. The actual situation must be negotiated with the local government.
