What is the difference between wind power and photovoltaic power generation?

Another idea for the landlord, from the cost is indeed low, but it also depends on where you use it.

The place you use is sunny, so you still install solar energy, and the energy produced is more.

If you can't see the sun all day, use wind energy.

You can also consider wind and solar complementarity, which can make the wind energy ratio a little larger.

It shouldn't be necessary, install it at home, and be responsible for safety issues; If you buy it, it should be the manufacturer or sales manufacturer who will be responsible for this file.

ps: If you can't consume the 3000W of electricity at home, it will be sent to the grid; I can tell you that the number of your home meters will not decrease when you send electricity to the grid, but will only increase.

It must be that wind power is low-cost.

However, wind power generation is unstable, and if you are in a place with better wind resources, it is definitely better to use wind power to generate electricity.

Moreover, there are many off-grid wind turbine products for domestic use.

The cost of small-scale photovoltaic power generation is high, and there are not many practical applications, so it is difficult to say.

If you don't use it at home, it doesn't seem to require any formalities.

If you want to get into the grid, it's basically impossible...

I see a lot of small wind turbines in Inner Mongolia, and if you are interested, you can check the relevant information.

Wind power generation is low, and now small wind turbines have been commercialized for a long time, ** low, and solar energy is relatively high due to the lack of familiarity in domestic silicon panel technology! But when you choose which of the two, you also have to consider the sunshine and wind energy in the place where you want to install the plant!

That depends on your home is in**, their work efficiency is limited by geographical location, you have to apply to get the state subsidy, you can also apply, I personally recommend that you install photovoltaic power generation on the roof of your own house is more appropriate, I am not very clear about the procedures.

The difference is that the reflow method is different, photovoltaic tends to have a relatively high input voltage and average current, while the current of wind power generation is very high and the voltage is average, and the energy of the wind farm is much greater than that of photovoltaics.

In this way, the detection standard of wind power is very harsh, for example, wind power requires the frequency point within 2kHz to be measured, and there are very few that can meet this national standard, including ZLG Zhiyuan Electronics' PA8000, which is more prominent in this field.

Wind energy. Wind energy resources are determined by wind energy density and the annual cumulative hours of available wind energy. Wind energy density is the power of the wind available per unit of frontal area, which is proportional to the cubic of wind speed and the density of air.

In modern times, turbine blades are used to convert the mechanical energy of the air flow into electrical energy to become a generator. In the Middle Ages and Antiquity, windmills were used to grind grain and pump water from the mechanical energy they collected.

Wind power is used in large-scale wind farms and some locations where the power supply is cut off, making a huge contribution to local life and development.

At present, domestic photovoltaic power generation and wind power generation are developing at full speed, they have very similar points, there are many differences, the difference is that the reflow mode is not the same, photovoltaic often input voltage is relatively high, the current is general, the current of wind power generation is very high, the voltage is general, and the energy of the wind farm is much greater than that of photovoltaic, so that the detection standard of wind power is very more demanding, for example, wind power requires the frequency point within 2khz to be measured, and there are very few that can meet this national standard. Among them, there is ZLG Zhiyuan Electronics' PA8000, which is a prominent instrument in this field.

PV is good,Although they all belong to the new energy sector, but the performance of photovoltaic in the first class is far better than wind power, the market's enthusiasm for photovoltaic is high, but the interest in wind power is not high, which is caused by a variety of reasons, mainly because the future prospects of photovoltaic are better, but investment is always a matter of odds, that is, a balance between risk and return.

The actual performance of 2020 is similar to that of photovoltaic and wind power, and the growth expectation in 2021, in addition to the high point of Follett, wind power and photovoltaic are also similar, and photovoltaic has no obvious advantage over wind power. However, the share price increase in the photovoltaic sector is significantly greater, with Sungrow reaching an astonishing 7 times and LONGi shares also doubling. The stock price reflects that the capital market is more optimistic about photovoltaics, implies the view on the future growth prospects of related companies, and the status of the industry, but also implies the optimism of Mr. Market.

The current valuation of leading enterprises is at a historical high, with LONGi 80%, Sungrow, Follett, Mingyang Intelligent, Riyue shares are all higher than 90%, Dongfang Cable 20%, Taisheng Wind Energy 5%, the latter two are the lowest. Overall, the share price of the photovoltaic sector has risen significantly, whether measured by dynamic P/E ratio, TTM, historical percentiles, and PEG, the current valuation of photovoltaic is higher than that of wind power, but the performance in 2020 and future performance are actually similar to wind power.

Photovoltaics are more promising.

Photovoltaic: It is the abbreviation of solar photovoltaic power generation system, which is a new type of power generation system that directly converts solar radiation energy into electrical energy by using the photovoltaic effect of solar cell semiconductor materials.

At the same time, the classification of solar photovoltaic power generation systems, one is centralized, such as large-scale northwest ground photovoltaic power generation system; One is distributed (with 6MW as the boundary), such as the rooftop photovoltaic power generation system of industrial and commercial enterprises, and the rooftop photovoltaic power generation system of residential buildings.

Solar power generation is an emerging renewable energy technology, and the main industrial applications are solar photovoltaic power generation and solar thermal power generation. Solar photovoltaic power generation has the characteristics of modular battery components, convenient installation and maintenance, and flexible use mode, and is the most widely used technology for solar power generation.

Solar thermal power generation uses the concentrating heat collection system to heat the medium, and then uses the traditional steam power generation equipment to generate electricity, and in recent years, the number of industrialization demonstration projects has begun to increase.

China** continues to introduce policies to support the development of the photovoltaic industry, especially when it is squeezed by the United States and the European Union, and correspondingly expands the domestic installed capacity market to protect the sustainable development of the domestic industry.

Personally, I think photovoltaic is more promising, because wind power generation will be restricted by the environment, some places are windy, some places are small, but photovoltaic is different, as long as there is sunlight, you can generate electricity.

On the other hand, wind energy also has the disadvantages of low wind energy density, unstable wind power, large regional differences in wind energy distribution, and certain environmental problems: 1. Low wind energy density 2. Unstable wind 3. Large regional differences in wind energy distribution.

Solar thermal power generation is a technology that converts light energy into heat energy, and then generates power generation through the traditional thermal cycle, which produces alternating current. Photovoltaic power generation is the sunlight irradiating high-purity silicon, so that the electrons transition, forming a potential difference, light energy is directly converted into electrical energy, which produces direct current.

PV already has a unified national benchmark electricity price, while CSP still uses concession bidding or a case-by-case electricity price.

The LCOE of photovoltaic is lower than the cost of solar thermal electricity, and the economy is good. At present, the cost of photovoltaic electricity is about yuan per kilowatt hour, and the cost of solar thermal electricity is about yuan per kilowatt hour.

The photovoltaic power generation industry chain is relatively mature and develops rapidly, and the installed capacity of power stations has grown rapidly. The CSP industry has just started, the industrial chain is not perfect, and the industrial development is facing many problems such as the selection of technical routes, the localization of related key equipment, and system integration.

There is more national policy support for photovoltaic power generation, and the recent national policy support for solar thermal power generation is not obvious.

Personally, I think that photovoltaic power generation has advantages.

Photovoltaic power generation costs less than wind power, making it the cheapest renewable energy in the world.

The cost of solar power has fallen to a third of what it was in 2010, making it the cheapest renewable energy source available.

According to data from Bloomberg New Energy Finance, solar energy has become the cheapest way to generate electricity in the world.

According to an analysis by Bloomberg New Energy Finance, the cost of solar power in China, India, Brazil and 55 other emerging market economies has fallen to a third of what it was in 2010. This means that solar energy has overtaken wind to become the most expensive renewable energy source available. In addition, it costs less than coal and natural gas.

In a letter to clients this week, Michael Liberlich, chairman of Bloomberg New Energy Finance, noted that solar energy has entered an era where it is enough to "weaken fossil fuels".

According to Bloomberg New Energy Finance, in 2016, there was a significant decline in solar power. Early last year, a power contract in India was closed at $64 per megawatt hour. Last August, a power contract in China was as low as US$ per megawatt-hour – about half of what coal could do.

At this stage, wind energy is more powerful!

Advantages of wind energy: 1. Clean, good environmental benefits; 2. Renewable, never exhausted 3, short infrastructure cycle 4, flexible installed capacity.

Disadvantages of wind energy: 1. Noise, visual pollution 2, occupying a large area of land 3, unstable and uncontrollable 4, the current cost is still high 5, and the environmental dependence is high.

The only downside of solar energy: the high cost. However, I believe that with the improvement of scientific research strength, the cost problem can be solved.

Dear, for you to inquire which wind power or photovoltaic is more promising, the answer is as follows:

Wind power is unlimited, but I personally think that the prospect of photovoltaic is still greater than that of wind power, for the following reasons:

Coupled with site selection, foundation, etc., there is only the best to play at present. In contrast, the threshold for photovoltaic is much lower: panel + inverter + grid-connected device, the cost of a set of small households is about 10,000 yuan, and it is not excluded that there will be subsidies such as "photovoltaic to the countryside" in the future;

2.Stability: The randomness of "wind" is too strong, and it is difficult to achieve stable power generation anywhere except along the coast.

Some people may say that the weather is also sunny, cloudy, and rainy, and photovoltaics are also unstable. Yes, but don't be limited to one place, you can pay attention to the weather map of the weather forecast, except for the rainy season, there are only a few places where it will rain most of the time, and this can solve the problem of electricity consumption through grid distribution.

3.The essence of wind energy is still solar energy: wind is caused by atmospheric pressure differences, air pressure differences are caused by temperature differences, and temperature differences are caused by the differences in solar energy in different regions (of course, the specifics are much more complicated, non-specialists), but in the final analysis, wind energy is still converted from solar energy.

The efficiency of direct use of solar energy is undoubtedly higher than that of indirect use. Of course, in the future, clean energy will definitely be composed of different parts of light, wind, water and nuclear, but before controlled nuclear fusion is commercialized, photovoltaic power generation is undoubtedly the most promising to become the main force of clean energy.

Wind power photovoltaic refers to the integrated application of wind power generation and photovoltaic power generation. Wind power and photovoltaic power are one of the more mature and widely used renewable energy sources, both of which have the advantages of pollution-free, resource-rich and renewable, which can effectively replace traditional fossil energy, reduce greenhouse gas emissions, and reduce the impact on the environment.

In a wind power photovoltaic system, wind power and photovoltaic power generation can complement each other to achieve stable and sustainable energy**. On the one hand, wind power has a wide range of applications, especially in some mountainous areas, deserts and coastal areas and other areas with rich wind energy resources. On the other hand, photovoltaic power generation is suitable for sunny areas, such as the southern region. Therefore, the combination of wind and photovoltaic power can make full use of the region's natural resources to achieve sustainable energy production and utilization.

In practical applications, wind power and photovoltaic power are generally used together with energy storage technology to solve the problems of energy consumption storage and peak shaving. In addition, with the continuous progress of technology and the reduction of costs, the application scope of wind power photovoltaic will continue to expand, becoming one of the important means to promote sustainable development.

Wind power and photovoltaic power are both important links in the carbon neutrality plan, and they can be regarded as a relatively old concept in clean sock energy.

Wind power refers to wind power generation, through which the kinetic energy of Fenglu Town is converted into electricity, and there is no carbon emission in the entire power generation process.

Summary. Kiss, keep you waiting! Under the same conditions (climate, light, humidity, etc.), wind energy conversion is about 30%-40%, while solar energy conversion is in the range of 15%-20%.

In other words, compared with the lowest conversion efficiency, wind energy is 30-15=15 percentage points higher than solar energy; Compared with the highest conversion efficiency, wind energy is 40-20=20 percentage points higher than solar energy. Based on the above conclusions, it is concluded that the efficiency of wind power is 15%-20% higher than that of photovoltaic power generation.

Kiss, keep you waiting! For the same amount of electricity (climate, light, humidity, etc.), the conversion of wind energy is about 30%-40%, while the conversion of solar energy is in the range of 15%-20%. That is to say, the minimum conversion efficiency is 30-15=15 percentage points higher than that of solar energy; Compared with the highest conversion efficiency, wind energy is 40-20=20 percentage points higher than solar energy.

Based on the above conclusions, it is concluded that the efficiency of wind power is 15%-20% higher than that of photovoltaic power generation.

Warm to you, dear: wind energy and solar energy are new energy development and utilization technology, relatively mature energy field, the former is through the windmill to convert wind energy into electricity, the latter is through photovoltaic equipment to convert solar energy into electricity, both are more common. Compared with the two, wind energy can be used as long as there is wind, regardless of day and night, so the efficiency of wind energy conversion and utilization will be higher; The installation of photovoltaic equipment requires a large space, and the site selection is restricted by the lighting conditions, and the maintenance cost of the equipment is relatively high.

I hope I can help you, you can contact me if you encounter any problems in the field of new energy in the future, I will try my best to answer every question you have, I wish you a happy new day! <>
