1.Structure of



Polycrystalline Silicon Solar Panel for 250W

I. High efficiency crystalline silicon solar cell. Even if under the weak light, the solar module can produce maximum power output.

II. Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.

III. EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.

IV. AI frame: Without screw, rner connection. 6 holes on the frame can be installed easily.

V. Junction box: Multi function junction box with water proof.

VI. Long lifetime: ≥25 years; Less power decrease.

VII. Good performance of preventing from atrocious weather such as wind and hails.

VIII. Resisting moisture and etching effectively, not effected by geology.

IX. The certificate issued by international authority: UL, TUV, IEC, CE.

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 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 main material for making solar panels?
If you make your own, in addition to buying silicon also need to buy for the packaging of silicon photovoltaic glass and EVA film.
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: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 power generation system consists of solar cells, solar controllers, batteries (group) composition. If the output power is AC 220V or 110V, also need to configure the inverter. The role of each part is
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: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: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.
