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:Single crystal solar panels and polycrystalline solar panels
monocrystalline silicon market share and a slight increase, and now the market to see the majority of single-crystal silicon cells. Monocrystalline silicon solar cell silicon crystal is very perfect, its optical, electrical and mechanical properties are very uniform, the color of the battery is mostly black or dark, especially for small pieces of small pieces of consumer products.
Q:What is the difference between solar panels and light panels?
Crystalline silicon cell conversion rate, rich in raw materials, is a large-scale commercial production of the battery, but the crystal silicon battery brings the harm can not be ignored. Crystal silicon series of batteries have a "three high more than a" common problem. High cost, high energy consumption, high pollution, byproducts and other shortcomings.
Q:Can solar panels be connected directly to motor?
If the DC motor, solar panels generated by the power through the controller, and then can be used; for AC motors, solar cells to the power through the controller and inverter (DC into AC), and then can be used.
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
Because the MPPT controller has a wider input voltage range, it can also convert multiple voltages into current charge and better protect the battery.
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:What is the principle of solar panels work?
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. This is the photoelectric effect of the working principle of solar cells.
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.
