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:Can cold light make solar panels power
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: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:What is the difference between solar panels and light panels?
The highest conversion efficiency in the laboratory is 24.7%, and the efficiency of the scale is 16%. Polysilicon conversion rate of 14% -15%. Amorphous silicon conversion rate of 12%. Silicon film conversion rate of 9%. Silicon solar cell is the main raw material of silicon, silicon is an extremely rich element of the earth, almost everywhere there are silicon, can be said to be inexhaustible, with silicon to create solar cells, raw materials can be described as no shortage.
Q:What is the principle and structure of solar panels?
inverter: solar direct output are generally 12VDC, 24VDC, 48VDC. In order to provide power to 220VAC appliances, it is necessary to convert the DC power from the solar power system into AC power, so it is necessary to use DC-AC inverter.
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.
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:Composition and function of solar panels
Used to bond fixed tempered glass and power generation (battery), transparent EVA material directly affect the quality of the component life, exposure to the air in the EVA easily aging yellow, thus affecting the component's light transmittance, thus affecting the components
Q:Solar panels single crystal and double crystal in the rain which is easy to use
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.
