Advantages of solar energy
(1) Universal: The sun shines all over the earth, without any regional restrictions. It can be developed and used directly on land or in the sea, in mountains or islands, and it is easy to collect without mining and transportation. (2) Harmless: The development and utilization of solar energy will not pollute the environment. It is one of the cleanest energy sources, which is extremely valuable in today's increasingly serious environmental pollution. (3) Huge: The solar radiation energy reaching the earth's surface every year is equivalent to 130 trillion tons of coal, which is the largest energy that can be developed in the world today. (4) Long term: According to the estimation of the rate of nuclear energy generated by the sun, the hydrogen storage is enough to last for tens of billions of years, while the life of the earth is also about billions of years. In this sense, it can be said that the sun's energy is inexhaustible.
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.
