Wind power and photovoltaic supporting grid connection projects refer to the installation projects of power generation equipment inverters and transformers to grid lines and equipment. According to the relevant information, the grid connection project is the installation project of your power generation equipment inverter, transformer to the grid lines and equipment. The grid connection is actually the grid connection operation project after the grid connection project is completed.
Which one is cheaper, wind power generation or photovoltaic power generation?
Both photovoltaic and wind power are currently recognized as new clean energy sources with little impact on the environment.
However, although it is claimed to be clean energy, strictly speaking, whether it is photovoltaic or wind power, it will have a certain impact on the environment.
For example, photovoltaics will have the following impacts on the environment:
1. The layout of 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 power 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 rainfall zones.
Leaving aside whether the above statement is accurate, the two new energy sources of photovoltaic and wind power themselves have not yet achieved 100% no impact on the environment. ...it will have some impact to some extent.
Of course, compared with traditional energy sources, photovoltaic and wind power have very little impact on the environment and are environmentally friendly enough. This is why these two new energy sources and other new energy sources have such advantages. extensive development.
Which one 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 power generation is also an emerging industry with good prospects.
Photovoltaic power generation equipment takes up less space and is also suitable for use in cities. Wind power generation equipment needs to be used in places with stronger winds, and these places must be far away from big cities.

Advantages and disadvantages of photovoltaic power generation:
1. Advantages of 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, In addition to no pollution emissions, it is absolutely clean (no pollution);
③It is not restricted by the geographical distribution of resources, and can take advantage of the advantages of building roofs; for example, areas without electricity and areas with complex terrain;
④Can generate electricity and supply electricity on site without consuming fuel and erecting transmission lines;
⑤High energy quality;
⑥UsePeople can easily accept it emotionally;
⑦The construction period is short and the time it takes to obtain energy is short.
2. Disadvantages of photovoltaic power generation
① The energy distribution density of irradiation is small, that is, it takes up 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 power generation is high.
④The manufacturing process of photovoltaic panels is not environmentally friendly.
