That is the sun: the Sun gives us light and heat, it is the main energy source of the planet and brings illumination all over the world. The importance of the sun encompasses each one of the living beings. The sun helps plants to nourish themselves through photosynthesis, and without sunshine, there would be no plants, and without plants, there would be no animals and no animals there would be no living beings on the planet.
The Sun is a star, which has millions of years existing in the Galaxy and whose main function is to give warmth, light and energy. For the Earth, it is of vital importance, because thanks to its presence today we can enjoy life as we know it. Its importance is that necessarily ignore of its presence because at the biological level the human needs to regulate the temperature of the body, the same happens with the animals and the plants.
As we recognize we want and we need solar energy because it is an inexhaustible and ecological source, because we must respect the planet in which we live. Solar photoelectric energy is a type of renewable energy from which you obtain electricity in a clean and ecological way through the rays of the sun. Solar energy is captured by metal sheets called photoelectric cells. These cells are coated with a material that produces a photoelectric effect. That is to say, they absorb photons of light and emit electrons that are captured, producing a usable electric current. This system also has the ability to store energy for night or several cloudy days.
The greater use of photoelectric solar energy is for the generation of non-polluting electricity for the supply of houses or small buildings. There are companies dedicated to the installation of the solar panels and the necessary systems so that a house has everything necessary to maintain an optimal energy consumption. This system implies an investment but it is amortized in a short time since the electricity provided by the photoelectric cells is free while the normal service increases faster and faster. In addition, the solar panels are guaranteed for 15 to 20 years and have barely been maintained.
Advantages of renewable energy
Solar panels produce renewable and ecological energy.
Its installation is fast and with little work.
The initial investment is amortized in a matter of few years and will have free electricity.
Photoelectric solar power makes it easy to have electric current in hidden areas or away from power lines.
The most important eco advantage logically speaking is that it implies a constant renewable energy supply for your home or business.
Solar thermal energy: It works with panels that absorb the solar rays transforming in caloric energy. They also have the ability to store it to continue exercising their activity at night or on cloudy days. We use it in the home to cook, to produce hot water, as water heaters or for heating.
