Solar Panels

February 13, 2012 | Comments: 0 | Views: 176

In general, solar energy can be described as the energy that is received from the sunlight and converted by a mechanical source for home use. It's cheaper and reliable for operations since the sun is readily available. On the other hand, solar panels are the mechanically built materials whose main purpose is to convert solar energy to electrical energy. They are built from an element called silicon. It is the core duty of the silicon element to covert the solar energy to electricity. The solar power can either be directly or indirectly gotten from the sunlight. When it's cloudy the intensity of the solar power delivered perfectly, the photovoltaic solar materials deliver sun rays into electricity and the solar thermal receiver changes the solar power into heat solvents, such as oil and water. This type of power is used in, iPod chargers, charge batteries water heaters, cell phone chargers and spacecrafts.

How do solar panels work? They practically work on the photovoltaic invention. Its name is derived from the technology used, which is also known as PV, which is made from silicon element. They are basically semiconductors made from sand built into large computer chips. When sun rays falls on the PV materials, the PN junction in it with its metal conductor helps produce electricity. At this juncture, the PN junction is the positive and negative charges that assist to produce electric current. Solar energy is available in different systems, grid connection, inverters and power storage. In a different system, the PV takes up large space up the roof to produce more energy. It can also be built on land space and produce up to 5-9 Megawatts per hour. They can also be useful in street lighting.

How are solar panels made? They are basically made from three-dimensional points; the crystalline silicon production, the crystalline silicon panels and the amorphous silicon panels. This stand of the solar-energy production is what is used in the present. In the crystalline silicon production, for example, when the silicon element is melted and cut it is named the poly crystalline silicon. In its other mode when it is built and cut, it becomes mono-crystalline silicon. In both cases, they are about; a hundred percentage pure silicon. In the second case of the crystalline silicon panels, they are normally broken into pieces and then sliced, finally being polished with doping materials. This changes the state of electric charge inside them to cells. The amorphous silicon panels are made from silicon alloys combined with multilayer cells for energy production. This combination explains how the solar power is made.

What are latest technologies of solar panels? The newest technology of solar energy has emerged in a wide range of things. This starts with the green power alternatives which is common for home use. The other aspect of it is the Power cooling and heating systems in homes. The high-technology appliance and periodic lighting at home is the other good examples of solar-energy development. New personal computers development for smart homes is also left out of the latest ideas of the solar power.

Yusuf Chy writes extensively on Solar panels, and provides information on how to install solar panels.
