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.
8,760,000 yuan.
The installed solar power capacity per acre is approximately 60 kW and the daily electricity generation is approximately 240 degrees. One-year electricity generation profit = 240 kilowatt hours of electricity * 365 days * 1 yuan / kilowatt hour of electricity = 8,760,000 yuan. This is the theoretical electricity production benefit of an acre of solar energy. However, solar energy cannot produce electricitycited in rainy weather, if the influence of rainy weather is removed, the profit of solar power generation per acre of land will not reach 87,600 yuan per year.
Solar panels are devices that absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy via photoelectric or photochemical effects. The main material of most solar panels is "silicon", but due to the cost of production. relatively high, its widespread use therefore still has certain limitations.
