Comparison of wind power generation and polycrystalline silicon photovoltaic power generation:
Wind power generation and polycrystalline silicon photovoltaic power generation have the advantages of green energy power generation, but wind power generation does not have to be like the high energy consumption and environmental pollution of polycrystalline silicon manufacturing. Therefore, Relatively more environmentally friendly.
Both wind power generation and polysilicon photovoltaic power generation have the disadvantages of high cost, insufficient power generation reliability, and low annual effective utilization hours. Generally, the cost of conventional thermal power generation equipment systems is about 5,000 yuan per kilowatt, while the cost of wind power generation and polycrystalline silicon photovoltaic power generation systems is about 10,000 yuan per kilowatt. At the same time, the annual effective utilization hours of wind power generation and polycrystalline silicon photovoltaic power generation are They are all about 2,000 hours, but the annual power generation hours of conventional thermal power stations are mostly 6,000 hours to 7,000 hours, and their stability and reliability are much higher than those of wind or photovoltaic power generation systems.
Wind power generation systems do not occupy as large an area as photovoltaic power generation systems. Photovoltaic power generation systems often occupy hundreds of acres, which is not as good as wind power generation systems. However, wind turbines make a lot of noise and cannot be installed in residential areas. However, photovoltaic systems can be installed on the roof of a home at will.
Therefore, both types of green power generation facilities have their own advantages and disadvantages. If we must compare multiple indicators, it seems that the photovoltaic system is better in the north where the sunshine resources are better, while in the south where there is more rain and rain, the wind power generation system seems to be slightly better. a little.
?I have wondered before, what is that. After all, I was quite curious when I saw a small fan spinning on a telephone pole. So I asked my brother, who was older than me at the time.
?He told me that it was used to generate wind power. In fact, I have seen news about wind power generation a long time ago. Energy saving and new energy are more popular now. Solar energy and wind energy are relatively clean energy sources that we currently know.
?In fact, clean means that it has no pollution. According to my observation, when I took 212 to the school, I found that there were many street lights on the road close to the school, and there was something like a small fan on each of these street lights. It has three leaves, and there is a solar panel at its lower part. Sometimes it keeps turning, and sometimes it stays there quietly.
? We are located in the middle of the Yangtze River, and there are no other buildings around our school except our school. The wind here is still relatively strong. There is also plenty of sunlight, so the street lights are on every day, and the brightness is pretty good, except on rainy days.
? When I didn’t know about it before, I thought it was a decoration. When I went to Shandong before, I saw a wind power generation base somewhere.
?There is a relatively large fan-like thing about one or five meters away. It is the same as the one on the telephone pole, but it is bigger than the one on the telephone pole. It was in the car at that time. Yes, I saw the three big leaves whirring and whirring. At that time, I knew for the first time that the windPower generation uses fan-like blades that rotate whirringly.
? So, I am now very sure that the fan-like thing on the telephone pole is used to generate wind power and convert wind energy.
