Solar cells make electricity from sun rays

The sun has great power - but it shows immediately. That's why there are special plants that make up the beam current.

Such is a solar system. It produces electricity - and that alone is the sun's rays

If you're out and about in the summer, you can feel it very well: solar radiation have a lot of energy. They make the skin hot, sometimes really hot - and when you are on a lake or an ocean, you realize that the sun also warms the water, so you can bathe in it. Think about it, how much energy is needed to heat a lake or a whole ocean. An awful lot. And this is just a small part of the huge force that has the sun.


From solar radiation can also be made ​​current. The conversion of light energy into electrical energy is called photovoltaic. These solar cells are necessary, which consist of silicon. This is a chemical element that glows blue. Solar cells are so blue. The energy of the sun's rays directly into electricity, they can.

Power is now made ​​with solar panels, which consist of thousands of solar cells. The modules are about as big as a desk top. Solar parks where there are many such modules can generate as much electricity as a small coal-fired power plant. But solar farms are much more environmentally friendly than coal-fired power plants. Therefore, to be built more and more of them - like now in Großhansdorf
