sun or solar When talking about converting photos into electricity, everyone will think of installing solar cells ติดตั้งโซล่าเซลล์ . which is really sunlight. It is a form of energy that is transformed from nuclear fusion reactions on the Sun. by fusion reaction It is a nuclear fusion reaction with hydrogen nuclei. to become the nucleus of the element helium This nuclear reaction emits heat energy and electromagnetic waves. solar energy It is an essential energy for all life on earth.
The sun is a dense cloud of hot gas. At the Sun’s surface, the temperature is about 5,700 Kelvin. It has a temperature of several million Kelvin. Its density is about 100 times the density of water. The sun can be compared to a nuclear fusion reactor. The sun emits energy in the form of electromagnetic waves of all wavelengths.
The sun is the direct and indirect source of energy. The direct energy that the sun gives to the earth is light and heat, warming the earth. The indirect energy of the sun is to sustain all living things. In particular, plants need sunlight for photosynthesis. or food production
Solar energy is the source of almost every kind of energy in the world. Causing the water cycle, solar energy is considered one of the renewable energy with high potential, non-polluting. and also the source of energy It is the source of chemical energy in food. Through the process of photosynthesis of plants is the origin of wind energy. When sunlight reaches outside the Earth’s atmosphere There will be an average light intensity of about 1,850 watts per square meter. But before coming down to the earth Some of the energy must be lost when passing through various atmospheres that surround the earth such as the ozone layer, water vapor layer, and carbon dioxide layer, causing the light intensity to decrease to approximately 1,000 watts per square meter. or about 70 percent
by 30% of this energy will be reflected back into space. The rest of the energy will be absorbed by the clouds. It is estimated that the amount of solar energy absorbed by the Earth in just over an hour is about the same as that of the Earth’s annual energy use. Or simply say that if we can use solar energy efficiently. We may not need to think of other energy to use at all.
Sunlight is a form of energy that is transformed from nuclear fusion. The sun is directly or indirectly the source of almost everything that exists in the world. Direct is light, which has the effect of producing heat. warm the world The indirect energy is the sun, enabling living things to exist. In particular, plants grow by using photosynthesis from sunlight. And humans have relied on energy from important trees, teeth, charcoal, and when plants and animals die and accumulate for a long time, it becomes coal and petroleum.
“Sunlight” is the largest source of natural energy. It is clean and ubiquitous energy. But the utilization may still have some limitations. For example, installing solar cells ติดตั้งโซล่าเซลล์ That will store energy from the sun during the sunlight. And this is one limitation. because sunlight only exists during the day as well as the intensity of light that is uncertain Because it depends on the weather and season.
Sunlight is an inexhaustible source of energy.
Light energy and thermal energy from the sun. It is an inexhaustible source of energy. Therefore, if human beings know how to efficiently convert light and heat energy from the sun into other types of energy. Humans no longer have to worry about the shortage of energy sources. Because the energy of light and heat from the sun is enormous compared to the amount of energy that humans need to use.
The most important thing is how to efficiently convert solar energy and heat into electrical energy. And the cost is low enough to compete with other energy sources. And the installation of solar cells is another option for converting solar energy.
Solar energy Occurs simultaneously with this world, but humans have just been able to change solar energy into electricity in the year 1839 by a scientist named Edmond Becquerel who has found that sunlight from the sun. can cause electric current in solid materials After this discovery, another 100 years later, mankind understood the process of change. Such a transformation is a process that takes place at the solar level into electrical energy, this is clearly atoms. and called this phenomenon Photoelectric or Photovoltaic
