Want to invest in a 50kw power station? Choose between wind power generation and photovoltaic power generation? invest? Payback?
According to my experience working in a design institute, for a 50kw power station, it seems that you can only choose photovoltaic power generation. Because the size of a single wind turbine is mostly above 1000kw (1MW). To use photovoltaic power generation, more than 20 photovoltaic panels are enough. flexible.
According to the current average cost, the investment per kilowatt of wind power generation and photovoltaic power generation is similar, about 10,000 yuan (including all equipment, installation, and boosting the Internet).
The return on investment is also similar. But if you are in an area with better wind resources, the return rate of wind power generation should be higher.
But with such a small scale, you can only choose photovoltaic power generation, and it will take 10 years to recover the investment.
Wind power generation, photovoltaic power generation, wave power generation development prospects, employment direction
To give the poster another idea, in terms of cost, wind power is indeed low, but it also depends on where you are. use.
The place you are using has no wind all day long but the sun is strong. Then you might as well install solar energy, which can produce more energy.
If you can’t see the sun all day long, use wind energy.
You can also consider the complementarity of wind and solar energy, which can make the proportion of wind energy larger.
It shouldn’t be necessary. If you install it at home, you are responsible for any safety issues. If you buy it, the manufacturer or seller should be responsible for this matter.
PS: If your home cannot consume this 3000W of electric energy, it will be sent to the power grid; I can tell you that the number on your home appliance meter will not decrease if power is sent to the power grid, but will only increase.
First of all, wind power and photovoltaic power generation are now new energy industries and are industries supported by the national government. It is developing faster now. But if you study now, you don’t know whether the state will still support this industry in a few years, and whether the industry will be reshuffled. (I am engaged in wind power generation and photovoltaic power generation. I am not familiar with the wave power generation industry. I wonder how the state supports this industry?)
Secondly, the general principles of these industries are the same, which is to use other The energy is converted into electricity, which is then fed into the national grid. Specific design includes metropolitan engineering design, system design, equipment research and development, power monitoring and display systems, and performance materials research and development.
The industries are all good industries. It also depends on the specific work department in the relevant industry and the specific nature of your work.
