What Is Solar Energy?

Solar energy is energy that comes from the sun. Every day the sun radiates, or sends out, an enormous amount of energy. The sun radiates more energy in one second than people have used since the beginning of time!

Where does all this energy come from? 

It comes from within the sun itself. Like other stars, the sun is a big gas ball made up mostly of hydrogen and helium. The sun generates energy in its core in a process called nuclear fusion. During nuclear fusion, the sun's extremely high pressure and hot temperature cause hydrogen atoms to come apart and their nuclei (the central cores of the atoms) to fuse or combine. Four hydrogen nuclei fuse to become one helium atom. But the helium atom weighs less than the four nuclei that combined to form it. Some matter is lost during nuclear fusion. The lost matter is emitted into space as radiant energy.

It takes millions of years for the energy in the sun's core to make its way to the solar surface, and then just a little over eight minutes to travel the 93 million miles to earth. The solar energy travels to the earth at a speed of 186000 miles per second, the speed of light.

Only a small portion of the energy radiated by the sun into space strikes the earth, one part in two billion. Yet this amount of energy is enormous.

Where does all this energy go?

About 15 percent of the sun

Maybe you've considered solar energy - even if only for a brief moment - only to dismiss it as too complicated and too expensive or maybe you're seriously considering a project, but don't know where to start. So here is the planning guide for Solar PV  home system. 

Why should you need to go with Solar?

If you’re thinking about going solar, there's no better time than now to do it. Government financial incentives are still ripe for the picking, the cost of photovoltaic (PV) cells is falling every day, and you'll probably be the first person on your block to make the jump. Adding solar energy to your house is an excellent project for several reasons: You'll be able to save loads on electricity, and may even be able to sell some of yours back to the utility company; you'll reduce your carbon footprint; and in doing so, you are contributing to worldwide adoption of this wonderful new energy source indirectly.

To help evaluate whether a home solar electric system will work for you, you should consider the following:

  • Your available solar resource -Do you have clear a
