Solar energy



Solar energy is the energy generated by the continuous nuclear fusion reaction of sunspots in or on the surface of the sun. The average solar radiation intensity on earth orbit is 1367w / ㎡. The circumference of the Earth's equator is 40000km, so it can be calculated that the Earth can obtain energy of up to 173000TW. The standard peak intensity at sea level is 1kw / ㎡. The annual average radiation intensity at a certain point on the Earth's surface for 24 hours is 0.20kw / ㎡, which is equivalent to 102000TW. Human beings rely on these energies to survive, including all other forms Renewable energy (except for geothermal energy resources), although the total amount of solar energy resources is equivalent to more than 10,000 times the energy used by mankind today, but the energy density of solar energy is low, and it varies from place to place, which changes from time to time, which is the development and utilization The main problem facing solar energy. These characteristics of solar energy will make its role in the overall energy system is subject to certain restrictions. The company is located in:


Although the solar radiation reaches the earth's atmosphere only at 2.2 billionth of its total radiant energy, it has reached as high as 173,000 TWh, which means that the sun shines on Earth every second and equals 5 million tons of coal. The wind, water, ocean temperature, energy of the waves, the energy of the waves and the biomass and some of the tidal energy on the planet come from the sun; even fossil fuels (such as coal, oil, natural gas, etc.) on Earth are fundamentally ancient Therefore, the broad range of solar energy to be included is very large. In a narrow sense, the solar energy is limited to direct conversion of solar radiation, photothermal energy and photochemistry. The company is located in:


Solar energy is both primary energy and renewable energy. It is rich in resources, can be used for free, but also without the need for transportation, the environment without any pollution. Creating a new life style for mankind and bringing society and mankind into an era of saving energy and reducing pollution.
