Q:What is the principle of solar panels work?
light - heat - electric conversion method through the use of solar radiation generated by thermal energy, 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 conversion process; the latter process is the thermo-electrical conversion process.
Q:Can cold light make solar panels power
permanent, clean and flexible three major advantages of solar cells long life, as long as the sun exists, solar cells can be an investment and long-term use; compared with thermal power, Solar cells do not cause environmental pollution
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 highest conversion efficiency in the laboratory is 24.7%, and the efficiency of the scale is 16%. Polysilicon conversion rate of 14% -15%. Amorphous silicon conversion rate of 12%. Silicon film conversion rate of 9%. Silicon solar cell is the main raw material of silicon, silicon is an extremely rich element of the earth, almost everywhere there are silicon, can be said to be inexhaustible, with silicon to create solar cells, raw materials can be described as no shortage.
Q:Polycrystalline solar panels are good or single crystal solar energy is good
Pre-monocrystalline silicon solar cell photoelectric conversion efficiency of about 15%, the highest reached 24%, which is all types of solar cells in the photoelectric conversion efficiency of the highest, but the production cost is so large that it can not be a large number of extensive And commonly used.
Q:The voltage and power problems of solar panels
3, charge 12V battery when the power is really small, if it is a normal controller, then the equivalent of 18V voltage in the charge, probably 18 x (240 / 30.2) = 143w solar panels.
Q:What is the principle and structure of solar panels?
inverter: solar direct output are generally 12VDC, 24VDC, 48VDC. In order to provide power to 220VAC appliances, it is necessary to convert the DC power from the solar power system into AC power, so it is necessary to use DC-AC inverter.
Q:Why can not the solar panel load directly?
Solar panels because of low power, and the output voltage is extremely unstable, not suitable for load.
Q:Composition and function of solar panels
Used to bond fixed tempered glass and power generation (battery), transparent EVA material directly affect the quality of the component life, exposure to the air in the EVA easily aging yellow, thus affecting the component's light transmittance, thus affecting the components
Q:Solar panels single crystal and double crystal in the rain which is easy to use
Polycrystalline silicon solar cell production process and monocrystalline silicon solar cell almost, but the polysilicon solar cell photoelectric conversion efficiency will have to reduce a lot of its photoelectric conversion efficiency of about 12% (July 1, 2004 Japan Sharp market efficiency of 14.8% Of the world 's most efficient polysilicon solar cells).
