Pure Energy

Exploitation of solar energy through solar panels

               Solar energy is the cleanest source of energy and is virtually inexhaustible. It can be captured by solar panels that absorb the Sun's heat, and hot water tanks hand to ensure hot water or heating contribution to a house or a swimming pool. Another type of solar panel is photovoltaic panels that absorb light rays and turn them into household electricity.
              Solar systems with direct heat transfer can not be used in applications where heating water quality problems (hard water or acid) because the risk of clogging or corrosion ainstalatiei. The price of solar installations is quite high, but over time can lead to energy savings of up to 70%.
                In summer, domestic hot water is virtually free, this being possible after depreciation costs of installing solar systems. It can make a substantial saving of 50-60% annually for residential space heating and 80-90% or even 100% for domestic water heating. The investment for an alternative source of hot hot water and heating, is amortized over a reasonable time of 3-4 years. This period is shortened when using intensive installation.

Why should you use solar energy:

Easy to install
It's a clean energy source
Long period of operation, over 20 years
Safety in use (there is no danger of fire, explosion)
Utility provides hot water throughout the year, winter in combination with a source of heat, reducing energy consumption costs by about 65%
Operating costs and minimal maintenance

Saving energy, we will live in harmony with nature and will protect future generations.

     Many believe that solar energy is a very recent technological breakthrough. In fact, its beginnings originated hundreds of years ago. Solar thermal power has been used for centuries to dry clothes and to preserve different types of food. Even children know that when you focus sunlight into a lens or a mirror can produce enough energy to light a fire.

     A definition of solar energy in the shortest form should read: electricity produced using solar light.

     Another definition, more accurate, it would be this: the energy received from the sun, in the form of sunlight, attracted by the solar panels or solar collectors and converted into electricity or heat.

      More than a hundred years ago, the inventors have discovered how they can capture sunlight for energy. They built impressive arrangements to fulfill this task and learned most of what we know today about solar energy.

     The oldest use of solar energy dates from 1860 and is attributed to Auguste Mouchout, professor of mathematics, French. He began work in this area due to concern that coal reserves which depended France is over. So he invented an engine that converts solar energy into electricity. Afterward, he and others have created devices more efficient solar energy. Shortly, this way of producing electricity turned into a work in progress continuously.

     In 1970, with the U.S. experienced energy crisis, solar energy came to light again. Many people were convinced that the nation would have to install photovoltaic panels on the roof of each building. To obtain thermal energy using a special rig that draws solar energy by using a solar collector. This type of energy was ideal for household water heating. Then, the crisis was over. Solar panels have become more expensive, and people back again behind solar energy and electricity.

     Nowadays, when we haunt a new energy crisis, solar power seems to be, again, all the better alternative.

     Electricity systems based on solar panels capture solar energy using photovoltaic cells. They need not necessarily of direct sunlight to produce electricity, but can generate and mud today, Deis, of course, not at the same level.

     Photovoltaic cells convert sunlight directly into electricity, which can be used in lighting or water heating in the household, etc.. For solar power using photovoltaic panels and thermal energy for water heating by using solar collectors.
Bear in turn, prevents the entire panel fotofoltaic sump system is considerably more than a solar collector.

     Solar energy has enough benefits, primarily that do not have paid monthly bills for electricity since sunlight is free. Also, it does not eliminate carbon dioxide or other pollutants. A system of solar panels could save a ton of carbon dioxide per year, which means more than thirty tons over life.

     A photovoltaic panel is made ​​up of layers of semi-conducting material, usually silicon. When light shines above it, it creates an electric head on layers. The more strong sunlight, the more energy is produced. Groups of photovoltaic cells are mounted together to build solar panels that are mounted on the roof.

     The power of a solar panel is measured in kilowatts. They are found in a variety of sizes and shapes. Most systems are based on a photovoltaic solar panel or more solar panels that fit on the roof.

     The initial investment in a photovoltaic system is expensive, but worth it, because then you get the free energy over the entire life.
