- 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: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: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 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: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:Polycrystalline solar panels are good or single crystal solar energy is good
- From the cost of production, than the monocrystalline silicon solar cells to be cheaper, easy to manufacture materials, saving power consumption, the total cost of production is low, so get a lot of development. In addition, the polysilicon solar cell life than monocrystalline silicon solar cells shorter. From the performance and price ratio, monocrystalline silicon solar cells also slightly better.
- 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?
- 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.
