The sun's luminosity is about 3.8 x 1026 Joules a second. In terms of mass, you can think of the total energy output as about 4,000,000 tons every second. When the curvature of the Earth and the density of the luminosity that hits our planet is considered, we receive only about 4.5 pounds per second of that energy.
More and more sunpower are used in the industrial and life of the people. It is getting popular now. No polluttion to our environment.We can get the sunpower by sunny power panel.
