Solar Although the energy radiated by the sun to the earth’s atmosphere is only 1/2.2 billion of its total radiant energy (about 3.75 X 1026W), it has reached 173,000TW, which is equivalent to the energy released by the complete combustion of 5 million tons of coal. Figure 1 shows the energy flow diagram on Earth. […]

Sun and solar radiation
The sun is the closest star to Earth, and it’s a fiery sphere of gas. Its diameter is about 1.4×106km, its mass is about 1.99×1030kg, and its average density is 1.4×103kg/m³. The main components are gaseous hydrogen and helium, of which hydrogen accounts for about 80%, helium accounts for about 19%, and other elements account […]
