INTRODUCTION of SOLAR ENERGY

Solar energy generally refers to radiation energy, generally used for power in present generation. Since Earth formations, organisms depends the sun heat and light to survive; human knows to use the sun to dry objects as food preservation methods such as the manufacture of salt and dried fish. We are starting to develop solar power under the situation of fossil fuel is less and less. Solar power is use of passive method (Photothermal conversion) and Photoelectric conversion. Photovoltaic system is a newly energy can be regenerated. Solar energy is the energy source of wind energy, chemical energy and potential energy of water, f ossil fuel is also called ancient energy.

Photoelectric conversion

Photoelectric conversion is called solar energy. Solar panels is an electricity generation device as it exposure to the sun, it will produce direct current. It consisting almost entirely of semiconductor materials (eg silicon) solid body made of thin solar cell components. With no m oving parts, it can be a long operation without causing any loss.

Simple photovoltaic cells for watches and calculators provide energy, photovoltaic systems for large buildings lighting, and to the power grid. Solar panels can be made into different shapes, but may be connected, to produce more power. In recent years, the surface of the roof and building components begin using photovoltaic panels, used as windows, skylights or obscure part of the installation, which is often called photovoltaic facilities attached to buildings photovoltaic systems.

Photothermal conversion

U.S. oil solar collector arrays, because they do not use expensive solar collector with mirror, therefore, it become the first one to achieve economies of scale solar power plants, the cost can be further reduced the amount of post modern solar technology can be polymerized sunlight and use its energy to produce hot water, steam and electricity. Solar collectors (Solar Thermal). Principle is the mirror reflected sunlight, focused on a glass tube called the receiver, and the hollow tube allows the oil flow. Sunlight reflected from the mirror will make the oil pipe heating, steam generation, and then by the steam turbine to generate electricity. [2] In addition to the use of appropriate technology to collect solar energy, a building can also take advantage of the sun's light and heat energy is added in the design of appropriate equipment, such as the massive south-facing windows or use the sun to absorb and slowly release heat building materials. At suitable locations, the cost of long-term use of solar energy has been close to or even lower than traditional fossil fuels.
