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 power generation 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 energy production:
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 exhaustion
②Safe; and reliable, no noise, In addition to not emitting pollution, it is absolutely clean (no pollution);
③It is not limited by the geographical distribution of resources, and can take advantage of roofs of buildings for example; , areas without electricity and areas with complex terrain;
④Can generate electricity and provide electricity on site without consuming fuel or erecting transmission lines;
⑤High energy quality;
⑥Easy for users to accept emotionally;
⑦The construction period is short and the time spent on obtaining energyie is short.
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.
