Solar Panels For Home An Investment And Long-term Use
The most common use of Solar Panels For Homes is used in a variety of lighting and household solar power systems, but in recent years, the designers come in handy, has been applied to all walks of life in the Solar Panels For Homes. After the design of these designers, Solar Panels For Homes and what the wonderful cross-border applications?
The solar cells into small modules, and then through the relevant platform to share. National designers can use this solar cell to innovate more fun and more meaningful solar applications.
A solar cell is a device that responds to light and converts light energy into electricity. There are many kinds of materials to produce photovoltaic effect, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, selenium and other copper. Their power generation principle is basically the same, now crystal silicon as an example to describe the optical power generation process. P-type crystalline silicon doped with phosphorus can be N-type silicon, the formation of P-N junction.
When the light is irradiated on the surface of the solar cell, a part of the photons are absorbed by the silicon material; the energy of the photon is transferred to the silicon atoms so that the electrons are transitioned and the free electrons are formed on both sides of the PN junction to form a potential difference. When the external circuit is turned on , In the role of the voltage,Solar Panels For Home there will be a current flowing through the external circuit to produce a certain output power. The essence of this process is the process of converting photon energy into electrical energy.
Solar power generation There are two ways of solar power generation: one is light → heat → electricity conversion; the other is the optical → electrical direct conversion.
(1) light → heat → electric conversion method: through the use of solar radiation generated by thermal power, usually by the solar collector will absorb the heat into the refrigerant refrigerant, and then drive the turbine power generation. The previous process is the light → heat transfer process; the latter process is hot → electrical conversion process, and the same as ordinary thermal power generation. The shortcomings of solar thermal power generation are inefficient and costly.
(2) light → electrical direct conversion method: the way is the use of photoelectric effect, the solar radiation can be directly converted into electrical energy, light → electrical conversion of the basic device is the solar cell. The solar cell is a device that converts solar energy directly into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When the sun shines on the photodiode,Solar Panels For Home the photodiode turns the solar energy into electricity. Current. When many batteries in series or in parallel can become a relatively large output power of the solar cell array.
Solar cells are a promising new power source with three advantages: permanence, cleanliness and flexibility. Solar cells can be used for long-term use; and solar power, compared to solar power,Solar Panels For Home solar cells can not cause environmental pollution; solar cells can be large and small simultaneously, large to one million kilowatts of medium-sized Power station, small to only one for the use of solar cells, which is unmatched by other power supply.
