Solar power thermocouple digital display instrument of related knowledge1

Solar power thermocouple digital display instrument is explosion-proof thermocouple for a new product, it takes advantage of solar energy power supply technology, today announced in detail what are the advantages of the solar energy. Solar energy is a kind of clean and renewable, more and more get the favor of people, have extensive role in people live, work, solar power is to convert solar energy into electrical energy, the solar cell is the use of solar energy work. And the working principle of solar thermal power plants is the use of sunlight, reduced the water to a boil into water vapor, and then used to generate electricity.

with the development of economy and the progress of the society, people put forward higher and higher requirements of energy, and find the current urgent task faced by human. There are mainly three kinds of existing electric energy source, namely, thermal power, hydropower and nuclear power.

the disadvantage of thermal power

thermal power needs to the burning of coal, petroleum and other fossil fuels. On the one hand, the less fossil fuel reserves is limited, the burning, are faced with the danger. It is estimated that the world oil resources in another 30 years will be withered. On the other hand burn fuel will emit carbon dioxide and sulfur oxide, thus causes the greenhouse effect and acid rain, the earth's environment.

the disadvantage of hydropower

hydropower a large amount of land is submerged, could lead to ecological environmental damage, and once had large reservoir, consequence will be unimaginable. In addition, a country's water resources is limited, but also to be influenced by season. Solar energy power station.

the disadvantage of nuclear

nuclear power under normal circumstances it is clean, but one thousand radiation leaks, the same terrible consequences. The former Soviet union at the chernobyl nuclear power plant accident, has 9 million people by different degree of damage, and this effect has not terminated.

solar meet the conditions of the

these are forcing people to look for. To meet two conditions: one is the rich will not dried up; 2 it is safe, clean, not threat to humans and damage the environment. Now find there are two main types, one is solar energy, the other is the fuel cell. In addition, wind power is auxiliary. Among them, the ideal is the solar energy.

solar power is the most ideal

light solar energy on the earth is very big, about 40 minutes of solar radiation on earth, a year is enough for the global human energy consumption. It can be said that the solar energy is really inexhaustible, inexhaustible energy. And solar power is absolutely clean, do not produce pollution. So solar power is known as is the ideal energy.

get electricity from solar energy, photoelectric transformation to implement should be carried out through the solar cell. It with other power generating principle of completely different, has the following characteristics: (1) no depleted danger; (2) absolute clean ( Pollution-free) ； (3) is not restricted by resource distribution area; (4) available in YongDianChu nearby power; (5) energy high quality; 6. Users from emotionally acceptable; All landowners get short time energy costs. Deficiency is: (1) light energy distribution density is small, namely to occupy large area; (2) the energy with the four seasons, day and night, rain or shine related meteorological conditions, etc. But on the whole, in spite of his flaws, as, solar energy has great advantages, because of this to the attention of the countries all over the world.

to make solar power truly reached practical level, one is to improve the efficiency of solar photovoltaic transform and reduce its cost, the second is to realize the solar co-occurrence in grid connected to the Internet.

solar power thermocouple digital display instrument learned that at present, the solar cell are monocrystalline silicon, polycrystalline silicon and amorphous silicon 3 kinds. Monocrystalline silicon solar cell conversion efficiency is highest, has reached more than 20%, but the price is also the most expensive. Amorphous silicon solar cell conversion efficiency low, but the price is the cheapest, the most promising in the future for general power generation will be the battery. Once it has large component of the photoelectric conversion efficiency of 10%, per watt power equipment price to $1 to 2, is enough to compete with now way of generating. Estimate can reach this level by the end of the century.

of course, special purpose and laboratory using solar cell efficiency is much higher, such as the Boeing company with development of gallium arsenide semiconductor gallium antimonide semiconductor overlap of solar electricity, photoelectric conversion efficiency can reach 36%, fast to catch up with the efficiency of coal-fired power generation. However, due to it is too expensive, can only be limited to the use on the satellite. Above is the solar power thermocouple digital display instrument simple analysis of the advantages of solar energy, believe that through this has been able to see the advantages of solar power thermocouple digital display instrument.
