Q:Why can not the solar panel load directly?
Power supply must be a number of individual battery strings, connected in parallel and tightly packaged into 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).
Q:What is the main material for making solar panels?
If you make your own, in addition to buying silicon also need to buy for the packaging of silicon photovoltaic glass and EVA film.
Q:Can cold light make solar panels power
The drawback of solar thermal power generation is that the efficiency is low and the cost is high, At least 5 to 10 times more expensive than ordinary thermal power plants.
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?
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
The demand for polysilicon is mainly from semiconductors and solar cells. According to the different requirements of purity, divided into electronic and solar level.
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
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 of solar panels work?
optical - electrical direct conversion method is the use of photoelectric effect, the solar radiation can be directly converted into electrical energy, optical - 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, 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
