Interesting facts about solar panels

There is no doubt that solar energy is the future of energy. There is no need to highlight humanity's constant search for ways not endeavor cleaner and more efficient for the supply of energy. And the Sun once again came to the rescue. The beneficial effects of the impact on every aspect of life on the planet, from the humblest forms the smallest life to humans. Without the Sun, it would be impossible to sustain all life. And, even more, increasingly sunlight as a source of clean energy and low cost. You can make your own solar panels and begin gradually to be independent of a supplier obliged: power company. Start with a device, a water heater, for example or heating for a room. Pretty soon you will feel safe enough, while you gain experience, to larger planes, such as completely based on the Sun to cover all the needs of energy.

Before you make your own solar panels, here are some facts about solar energy works, as they have been collected and storage. Solar cells, also called photovoltaic (PV), are the core of any device powered by the Sun. Tentatively began to be seen in small devices such as calculators, half a century ago. Yes, that long, surprising, right? Solar cells were first developed in 1958. Remember how we used to play covering the cell with one hand, and would shut down the computer. The same technology was used in satellites in outer space; to cover the needs of power supply for this man made space Crafts. Solar cells can "capture" up to 1000 watts of energy per square metre. A group of cells is called a solar panel.

Solar cells are made of semiconductors, a particular type of element that has the property of releasing electrons in the presence of a source of energy, in this case, the Sun's rays. These electrons will be put into circulation, so the energy is produced. The phase that has proved more difficult to achieve is storage. So far, solar energy has been stored in batteries, car batteries. Batteries are chemicals that de-composed and released ions — electrically charged particles. As it uses energy, substances within the batteries back to their original chemical composition. This system has proven to be a bit inefficient, due to limited battery capacity. A large number of batteries would be necessary to store and provide energy to a regular family home, let alone larger consumers, such as a factory or a car. Therefore, new ways to store energy should be developed.

First was the Sun that came to our rescue. Now, does the water. Yes, plain water has the ability to store energy, basically based on the same working principle battery: substance decomposition. In this case, water is decomposed into its two elements of composition: oxygen and hydrogen. Therefore, these two gases can be recombined inside a battery, provide cheap energy free of pollution.
