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: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 difference between solar panels and light panels?
Silicon solar cells are divided into monocrystalline silicon, polysilicon, amorphous silicon, silicon thin film solar cells and several. At present, the world's most widely used solar cells are silicon solar cells, in large-scale applications and industrial production is still dominated by the penetration rate of 90% or more, monocrystalline silicon solar cell photoelectric conversion efficiency of the highest technology is also the most mature.
Q:The voltage and power problems of solar panels
In general, the charging voltage is 1.5 times the battery voltage as well, that is 12V battery pack, select the 18V solar panels just.
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:How many solar panels have ah?
But in reality, the need for solar panel power and solar charger to find a balance in the portability. It is generally believed that the minimum power of the solar charger can not be less than 0.75w, and the secondary power solar panel produces 140mA of current under standard light. In the general sunlight generated by the current at 100mA or so, if less than the secondary power charging current is too small,
Q:Why can not the solar panel load directly?
Solar panels (also known as solar modules) are the core of solar power systems and the most important part of solar power systems.
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).
Q:Can solar panels be connected directly to motor?
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.
