Ten thousand kilowatt hours of electricity per day requires 66,667 kilowatt hours of photovoltaic energy. The specific calculation method is to calculate the amount of photovoltaic energy needed per day. You need to know the amount of electrical energy consumed per day. day, as well as the efficiency of the electricity production of the photovoltaic plant. Assume that the electricity consumed per day is 10,000 kWh and the electricity generation efficiency of the photovoltaic plant is 15%. The photovoltaic energy production required is: 10,000 kWh/15% = 66,667 kWh. In other words, a photovoltaic plant that produces 66,667 kWh of electricity per day is needed to meet the consumption demand of 10,000 kWh of electricity per day. Of course, this figure is only a rough estimate. The actual situation must also take into account the influence of factors such as the operating time of the centerphotovoltaics and weather conditions.
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 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.
