Dazhai Town, Kongtong District, Pingliang City, Gansu Province. According to Baidu map query, Dazhai Kongtong District photovoltaic power station is located in Dazhai Town, Kongtong District, Pingliang City, Gansu Province, China. The power plant covers an area of approximately 1,000 acres and has a total installed capacity of 200 megawatts. It is one of the largest photovoltaic power generation projects in Gansu province. Construction began in 2016 and was officially put into operation in 2018. It can provide local supplies every year. About 250 million kilowatt hours of clean electricity have effectively promoted local economic development and environmental protection.
What is the photovoltaic power generation capacity of 100 acres?
10,000 square meters, the annual electricity generation is 1,708,900 kWh and the average daily electricity production is 349 kWh.
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 cost 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.
Approximately 6 million degrees. 100 acres of land can be used to produce 6 megawatts of photovoltaic power. One megawatt of energy can generate 1,000 kilowatt hours of electricity per hour. 100 acres of land can generate 6 megawatts of photovoltaic power, which can generate 6,000 kilowatt hours of electricity per hour. hour. The cost of building a photovoltaic project on 1 mu of land is about 300,000 yuan, and the cost of building a photovoltaic project on 100 acres of land is about 30 million yuan.
