Solar energy (solar energy) refers to the heat radiation energy of the sun, mainly expressed in the form of sun rays. Usually used to generate electricity or provide energy for water heaters.

      Advantage

      1.Versatility: The sun shines on the entire land without geographical restrictions. It can be seen everywhere on land or oceans, mountains, and islands. It can be directly developed and used, and is convenient for collection without development and transportation.

     2. Harmless: The development and use of solar energy will not pollute the environment. It is one of the clean energy sources. Today, when environmenta pollution is becoming more and more serious, it is extremely valuable.

      3.Very large: the solar radiation reaching the surface of the earth each year is equivalent to about 130 trillion tons of coal, of which the total amount is the largest energy source that can be developed in the world today.

      4.Life expectancy: According to estimates of the rate of nuclear energy produced by the sun, hydrogen storage is sufficient to maintain a lifespan of tens of billions of years, and the life of the earth is about billions of years. In this sense, it can be said that the energy of the sun is unlimited.
