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: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:What is the working principle of solar panels?
No matter what kind of material to make the battery, the general requirements for solar cell materials are
Q:Can cold light make solar panels power
light - heat - dynamic - electric conversion method through the use of solar radiation generated by thermal power, usually by the solar collector will absorb the heat energy into the refrigerant, and then drive the turbine power generation. The latter process is the light-heat transfer process; the latter process is the heat-to-conversion process, which is the same as the conventional thermal power generation.
Q:What is the principle of solar panels to convert solar energy into electricity?
Silicon" is one of the most abundant materials on our planet, and since the nineteenth century scientists have discovered the semiconducting properties of crystalline silicon, it almost changed everything and even human thought. At the end of the 20th century, our lives were everywhere Crystal production and process can be divided into five steps: a, purification process b, drawing process c, slicing process d, the system of silicon Battery process e, packaging process.
Q:Single crystal solar panels and polycrystalline solar panels
Monocrystalline silicon solar cells are mainly made of monocrystalline silicon, compared with other types of solar cells, monocrystalline silicon cell conversion efficiency of the highest. In the early days, monocrystalline silicon solar cells occupied most of the market share, in 1998 after the retreat of polysilicon, the market share accounted for second. Due to the shortage of polysilicon raw materials in recent years, after 2004,
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.
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
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:How many solar panels have ah?
However, crystalline silicon (monocrystalline silicon and polysilicon) in the weak light is basically no current generation, amorphous silicon weak light type (in low light energy is rarely). So a comprehensive view, it is appropriate to use monocrystalline silicon or polycrystalline silicon solar cell materials. Second, the choice of solar cells 1, we buy solar cells, the focus is on the power of solar cells, in general, the solar panel power is proportional to the area of ​​solar chips.
