With the popularity of wind turbines, many areas with good wind energy resources are installing household wind turbines. How about small domestic wind turbines? Is it cost-effective? Let's compare the data.
1000W household wind turbine
Purchase cost: 1500-1800 yuan, we will calculate it at 1600 yuan
A household consumes more than 10- 20 kWh of electricity per day, and 15 kWh per day
At present, the national one-time electricity consumption is 0.52 yuan, about 7.8 yuan a day, and 2847 yuan a year. We charge 3000 yuan per year
If a 1000W generator works 12 hours a day (actually more than 12 hours), it will generate 12 kWh per day, which is 3 degrees different from 15 kWh per day. Annual power generation is about 2300 yuan
The service life of wind turbines is generally more than 10 years, and normal maintenance can reach 20 years. Calculated by the minimum 10 years, we actually get 23,000 yuan, which is equivalent to the cost of investment in the first year, and the next 6 years are free, not to mention the actual service life is more than 10 years.
In summary, the installation of small wind turbines is very practical and cost-effective. Wind energy is an energy-saving and environmentally-friendly renewable resource, and it also responds to national requirements.
