Q:What is the working principle of solar panels?
The production of solar cells is mainly based on semiconductor materials, its working principle is the use of optoelectronic materials to absorb light energy after the photoelectricity in the conversion reaction, according to the different materials used, solar cells can be divided into:
Q:What is the main material for making solar panels?
You can also according to their own needs, according to the power to buy a good package of solar photovoltaic products.
Q:What is the principle of solar panels to convert solar energy into electricity?
scientists have applied solar cells to space technology - communication satellites. At the end of the last century, in the process of human self-reflection, this clean and direct energy form for photovoltaic power generation has become more cordial, Not only in space applications, in many areas also show their talents. Such as: solar garden lights, solar power generation system, the village power supply independent system, photovoltaic pumps (drinking water or irrigation), communication power, oil pipeline cathodic protection,
Q:Single crystal solar panels and polycrystalline solar panels
monocrystalline silicon market share and a slight increase, and now the market to see the majority of single-crystal silicon cells. Monocrystalline silicon solar cell silicon crystal is very perfect, its optical, electrical and mechanical properties are very uniform, the color of the battery is mostly black or dark, especially for small pieces of small pieces of consumer products.
Q:What is the difference between solar panels and light panels?
The production of silicon requires that the stone be heated to become liquid, and the heating becomes gaseous crystals. During the need to burn a lot of fossil fuels and emissions of toxic gases silicon tetrachloride, this material has a corrosive effect on the skin. After pickling, pulling crystal, cut the side, finished a series of processes, more industrial chain. The cost of the finished product is too high. The energy consumption of making a solar cell requires solar cells to be equal in power generation for several years. The cost recovery period is very long.
Q:Can solar panels be connected directly to motor?
If the DC motor, solar panels generated by the power through the controller, and then can be used; for AC motors, solar cells to the power through the controller and inverter (DC into AC), and then can be used.
Q:Composition and function of solar panels
Among them, for the electronic grade polysilicon accounted for about 55%, solar grade polysilicon accounted for 45%, with the rapid development of photovoltaic industry, solar cell demand for polysilicon growth rate higher than the development of semiconductor polysilicon, is expected to 2008 solar polysilicon
Q:The voltage and power problems of solar panels
From morning to night (with sunshine) solar panel voltage is generally relatively stable, that is basically about 30V; but the output power is always changing, sooner or later, noon; if it is good quality solar energy,
Q:What is the principle and structure of solar panels?
solar panels: solar panels is the core of solar power generation system, solar power system is the highest value of the part. Its role is to convert the sun's radiation capacity into electricity, or sent to the battery to store, or to promote the load work.
Q:What is the principle of solar panels work?
The sun is irradiated on the semiconductor p-n junction to form a new hole-electron pair. Under the action of the p-n junction electric field, the holes flow from the n region to the p region. The electrons flow from the p region to the n region, and the current is formed after the circuit is turned on. This is the photoelectric effect of the working principle of solar cells.
