The difference between photovoltaic construction files and wind files lies in the different reflow methods. At present, domestic photovoltaic power generation and wind power generation are developing at full speed. They have many similarities and many differences. The return method is often different. The input voltage and average current are often relatively high. while wind power generation has many similarities. The current is very high, the voltage is medium, and the energy of wind farm is much higher than that of photovoltaics, so the testing standards for wind power are very strict.
Which photovoltaic or wind energy is less harmful to the environment?
In general, wind power plants benefit from relatively sufficient sunlight for reasons of location. To better use energyclean, they will. simultaneously The production of photovoltaic energy is carried out simultaneously with the production of wind energy. Simply put, photovoltaic power generation is the use of solar energy to produce electricity. Photovoltaic wind power refers to the simultaneous use of wind energy and solar energy to produce electricity.
Which is cheaper: wind power generation or photovoltaic power generation?
Photovoltaic power and energy wind power are currently recognized as new sources of clean energy with little impact on the environment.
However, even if it is claimed that it is clean energy strictly speaking, whether it is photovoltaic or wind energy, it will have a certain impact on the environment .
For example, photovoltaics will have the following impacts on the environment:
1. Installing photovoltaic panels will take up a lot of space.
2. During the production process of photovoltaic panels, trichlorosilane and silicon tetrachloride will be produced, which are substances that have an impact on the environment and human health.
For example, wind energy will also have an impact on the environment during the deployment process.
It is said that large-scale deployment of wind power will affect atmospheric circulation and cause changes in ambient temperature.
It is also said that large-scale deployment of wind power will affect the circulation of water vapor in the atmosphere and affect the distribution of precipitation areas.
Even if the above statement is accurate, the two new energy sources of photovoltaic power and wind power themselves have not yet achieved 100% impact on the environically. ...it will have some impact to some extent.
Of course, compared to traditional energy sources, photovoltaic and wind energy have very little impact on the environment and are sufficiently environmentally friendly. This is why these two new sources of energy and other new sources of energy have such advantages. extensive development.
Which is cheaper: wind power generation or photovoltaic power generation? Wind power is low, wind power costs about 4-5 yuan per watt, and photovoltaic power costs about 7-8 yuan per watt. Low-light photovoltaic panels are cheaper. As photovoltaic power generation technology, especially photovoltaic panels, continues to mature, the application of photovoltaic power generation continues to expand. Photovoltaic energy productionIt is also an emerging industry with good prospects.
Photovoltaic energy production equipment takes up less space and is also suitable for use in cities. Wind power generation equipment should be used in places subject to strong winds, and these places should be far from large cities.

Advantages and disadvantages of photovoltaic power generation:
1 . photovoltaic power generation
Compared with commonly used thermal power generation systems, the advantages of photovoltaic power generation are mainly reflected in:
①No risk of depletion
②Safe and reliable, no noise, no polluting emissions, absolutely clean (no pollution);< /p >
③ It is not limited by the geographical distribution of resources and can take advantage of the roofs of buildings, forexample, areas without electricity and areas with complex terrain
④ It can be used on; -site without fuel consumption or construction of transmission lines;
⑤ High energy quality
⑥ Easy to accept emotionally;
⑦ Short construction period and little time to obtain energy.
2. Disadvantages of photovoltaic power generation
① The energy distribution density of irradiation is low, that is, it occupies a huge area
② The energy obtained is the same as that of the four seasons, day and night, and it is related to weather conditions such as cloudy and sunny conditions.
③ At present, compared with thermal power generation, the cost of electricity generation is high.
④The manufacturing process of photovoltaic panels is not environmentally friendly.
