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.
