Solar Polycrystalline Series Panels

Introduction of our company

Just like the sun, we don’t see international borders as barriers, but as something we transcend in everything we do. From the way we think to the way we operate, our global employee community interacts with our customers, sales and service partners the world over.

 

We are active in 40 countries on five continents with subsidiaries in 11 countries. In fact, our efforts have contributed over 2.2 GW of solar energy to date.

 

We are also a unique player in what is becoming a global industry. Our sales and service units are owned by Kawa Capital Management, Inc.—based in Miami—making us independently owned and internationally backed. Kawa’s financial engineering expertise means we can offer innovative financing alternatives to our clients worldwide.

 

We are physically present in 11 key markets. That means we don’t just have a grass roots understanding of local needs, but a face to face relationship with our clients—as a consultant, point of contact, and partner.

 

We are even able to provide financial capital solutions for projects, no matter where they are to be developed.

 

Characteristics of Polycrystalline Solar Panels

I Solar Cell : High efficiency crystalline 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, corner 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.

Q:Why can not the solar panel load directly?
Power supply must be a number of individual battery strings, connected in parallel and tightly packaged into components.
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 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:Can cold light make solar panels power
permanent, clean and flexible three major advantages of solar cells long life, as long as the sun exists, solar cells can be an investment and long-term use; compared with thermal power, Solar cells do not cause environmental pollution
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:Polycrystalline solar panels are good or single crystal solar energy is good
. Since monocrystalline silicon is typically coated with tempered glass and waterproof resin, it is rugged and durable for up to 15 years and up to 25 years.
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 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?
light - heat - electric conversion method through the use of solar radiation generated by thermal energy, usually by the solar collector will absorb the heat into the refrigerant refrigerant, and then drive the turbine power generation. The previous process is the light-heat conversion process; the latter process is the thermo-electrical conversion process.
