Q:What is the principle of solar panels work?
Solar power generation There are two ways of solar power generation, one is the light - heat - electricity conversion, the other is the optical - electrical direct conversion.
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: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: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:Polycrystalline solar panels are good or single crystal solar energy is good
. Since monocrystalline silicon is typically coated with tempered glass and waterproof resin, it is rugged and durable for up to 15 years and up to 25 years.
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: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:What is the principle of solar panels to convert solar energy into electricity?
Solar cells are a pair of light response and can convert light energy into electrical devices. There are many kinds of materials to produce photovoltaic effects, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, selenium and other copper. Their power generation principle is basically the same, now the crystal as an example to describe the process of photovoltaic power generation.P-type crystalline silicon doped with phosphorus can be N-type silicon, the formation of P-N junction.
Q:Solar panels single crystal and double crystal in the rain which is easy to use
At present, 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. Since monocrystalline silicon is typically coated with tempered glass and waterproof resin, it is rugged and durable for up to 15 years and up to 25 years.
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.
