10,000 square meters, the annual electricity generation is 1,708,900 kilowatt hours, and the average daily electricity generation 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 stupidityPhotovoltaic 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.
50MW photovoltaic. The photovoltaic modules are installed on flat ground with supports at approximately 80 W/square meter. One acre of land is equivalent to 666 square meters, and 1,000 acres of land can probably install a 50MW photovoltaic power plant. The investment cost for installing a photovoltaic plant on 1,000 acres of land is about 600,000 yuan per acre of land, which is about 600 million yuan. cuntsided to the network, the cost can be recovered in approximately 6 to 8 years. Yes, it will be a net profit for about 15 years.
