10,000 square meters, the annual power generation is 1,708,900 kilowatt-hours, and the average daily power generation is 349 kilowatt-hours.
Generally, the area of a 250w solar photovoltaic panel is 1.65×0.992=1.6368m?, which is 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 must 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 an average of 6 hours of effective sunshine per day.
The annual power generation is approximately 24436×6×365=53514840 kilowatt-hours of electricity. At a 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 needs to be negotiated with the local government.
1. Calculate the power generation according to the following formula: W (kilowatt hour or degree) = power P (kilowatt) * time T (hour).
2. Known conditions for this question:
Power P=10,000 kilowatts=1*10000 kilowatts=10000 kilowatts;
Time T=365*24 hours=8760 hours (assuming there are 365 days of power generation in a year and 24 hours of power generation every day);
Therefore, the annual power generation of a one-kilowatt generator set is:
W=P*T=10000*8760=87600000 kilowatt hours or degrees.
The unit of measurement of the power generation W of the generator set is kilowatt hours or degrees (1 kilowatt hour = 1 kilowatt hour of electricity). When the power of the generator set is larger and the power generation time is longer, the power generation can also be converted into 10,000 kilowatt hours or 10,000 kilowatt hours (10,000 kilowatt hours = 10,000 kilowatt hours = 10,000 kilowatt hours). In this way, the result of this question can also be expressed as: 87600000/100 million kilowatt hours = 87.6 million kilowatt hours (10,000 degrees).
