Solar energy is the energy generated by the continuous nuclear fusion reaction process inside the sun
Solar energy is the energy generated by the continuous nuclear fusion reaction process inside the sun. The average solar radiation intensity in Earth orbit is 1369w/m2. The circumference of the earth's equator is 40076 kilometers, so it can be calculated that the energy obtained by the earth can reach 173000 TW. The standard peak intensity at sea level is 1kw/m2, and the annual average radiation intensity at a point on the earth's surface for 24h is 0.20kw/m2, which is equivalent to 102000TW of energy. Although the energy that the sun radiates into the earth's atmosphere is only 2.2 billion times of its total radiation energy, it has reached 173000 TW, that is, the energy that the sun shines on the earth every second is equivalent to 5 million tons of coal, and the energy that shines on the earth every second is 1.465 × 10 ^ 14 joules. Wind energy, water energy, ocean temperature difference energy, wave energy and biomass energy on the earth all come from the sun; Even fossil fuels on the earth (such as coal, oil, natural gas, etc.) are basically solar energy stored since ancient times, so the broad sense of solar energy covers a very wide range, while the narrow sense of solar energy is limited to the direct conversion of solar radiation energy into light, heat, photoelectric and photochemistry
Solar energy is a kind of renewable energy. It refers to the thermal radiation energy of the sun (see the three modes of thermal energy transmission: radiation), which is mainly represented by the sun's rays. In modern times, it is generally used to generate electricity or provide energy for water heaters. Since the birth of life on the earth, it has mainly lived by the heat radiation energy provided by the sun. Since ancient times, people have also learned to dry things in the sun as a way to make food, such as salt making and salting fish.
Characteristics of raw materials of solar modules Battery chip: High efficiency (above 16.5%) monocrystalline silicon solar chip packaging is used to ensure sufficient power generation of solar panel. Glass: Low iron tempered suede glass (also known as white glass) is used, with a thickness of 3.2 mm, and the transmittance is more than 91% within the wavelength range of solar cell spectral response (320-1100 nm). It has high reflectivity for infrared light greater than 1200 nm. At the same time, the glass can withstand the radiation of solar ultraviolet light without decreasing the transmittance.
