 FAQ of Polycrystalline Silicon Solar Panel Type CR290P-CR250P

(1) Can you offer the test report of the module?

     Sure. All the solar modules must pass necessary tests including EL test and ultra-red test and other visual test of the apperance, and the test report presents all the detailed data of the modules.

(2) How  to confirm about the quantity and the type of solar module?

     It depends on the solar system where  you want to put into use the solar modules. We have experienced engineers to design for your order and you need to give more information to fix the details.

 



Solar panel working process

In addition to being the ultimate source of all life on earth, the sun is an infinitely renewable, completely pollution-free source of electricity. Instead of burning fossil fuels dug up from the ground in a big power plant – a very 19th century, industrial age approach, when you think about it – solar panels convert sunlight directly into electricity, with no harmful emissions.

The basic unit of a solar panel is a solar cell, which usually consists of one or two layers of silicon-based semiconductor wafers. When struck by the photons in sunlight, the solar cell generates an electrical charge due to the "photovoltaic effect" – which is a pretty good name, since it produces voltage from photons. The flow of these electrons moves in a steady electrical current from one side of the cell to the other.

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
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:What is the working principle of solar panels?
The production of solar cells is mainly based on semiconductor materials, its working principle is the use of optoelectronic materials to absorb light energy after the photoelectricity in the conversion reaction, according to the different materials used, solar cells can be divided into:
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 principle of solar panels to convert solar energy into electricity?
optical cable communication pump Station power, seawater desalination system, urban road signs, highway signs, etc. Europe and the United States and other advanced countries will be integrated into the photovoltaic power generation system and remote areas of natural village power supply system into the development of the combination of solar cells and building systems have been formed industry Trends
Q:Single crystal solar panels and polycrystalline solar panels
Monocrystalline silicon cells in the laboratory to achieve the conversion efficiency of 24.7%. Ordinary commercial conversion efficiency of 10% -18%. Monocrystalline silicon solar cells because of the production process problems, generally its semi-silicon ingots for the cylindrical into, and then through the slice -> cleaning -> diffusion knot -> remove the dice -> the production of electrodes -> corrosion around -> Reflective film and other workers made of finished products. General monocrystalline silicon solar cells four corners for the fillet. Monocrystalline silicon solar cell thickness is generally 200uM-350uM thick, and now the production trend is to ultra-thin and efficient direction
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 and structure of solar panels?
solar controller: the role of solar controller is to control the working state of the entire system, and the battery played a charge protection, over discharge protection role. In the larger temperature difference, the qualified controller should also have the function of temperature compensation. Other additional functions such as light control switch, time control switch should be the option of the controller;
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.
