1. Structure of Polycrystalline Silicon Solar Modules 72Cell-305W Description

Solar panels can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications.

-Tests by independent laboratories prove that  modules:

 Fully conform with certification and regulatory standards.

 Withstand wind loads of up to 2.4kPa and snow loads of up to 5.4kPa, confirming mechanical stability.

 Successfully endure ammonia and salt-mist exposure at the highest severity level, ensuring their performance in adverse conditions.

- High effi ciency, multicrystalline silicon solar cells with high transmission and textured glass deliver a module effi ciency of up to 16.0%, minimizing installation costs and maximizing the kWh output of your system per unit area.

- Tight positive power tolerance of 0W to +5W ensures you receive modules at or above nameplate power and contributes to minimizing module mismatch losses leading to improved system yield.

- Top ranking in the “TÜV Rheinland Energy Yield Test” and the “PHOTON Test” demonstrates high performance and annual energy production.

Q:Solar panels single crystal and double crystal in the rain which is easy to use
At present, monocrystalline silicon solar cell photoelectric conversion efficiency of about 15%, the highest reached 24%, which is all types of solar cells in the photoelectric conversion efficiency of the highest, but the production cost is so large that it can not be a large number of extensive And commonly used. 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:What is the working principle of solar panels?
Based on the above considerations, silicon is the most ideal solar cell materials, which is the main reason for solar cells to silicon-based. But with the continuous development of new materials and related technology development, to other village-based solar cells are increasingly showing attractive prospects.
Q:What is the main material for making solar panels?
The correct name of solar panels is solar photovoltaic panels, making its main material is monocrystalline silicon or polysilicon silicon, monocrystalline silicon silicon chip more crystalline silicon wafer photoelectric conversion rate is high, the price is also more expensive silicon wafer.
Q:What is the principle of solar panels to convert solar energy into electricity?
scientists have applied solar cells to space technology - communication satellites. At the end of the last century, in the process of human self-reflection, this clean and direct energy form for photovoltaic power generation has become more cordial, Not only in space applications, in many areas also show their talents. Such as: solar garden lights, solar power generation system, the village power supply independent system, photovoltaic pumps (drinking water or irrigation), communication power, oil pipeline cathodic protection,
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: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:Composition and function of solar panels
In addition to the quality of EVA itself, the components of the manufacturers of laminated technology is also very large, such as EVA glue degree is not up to standard, EVA and tempered glass, backplane bonding strength is not enough, will cause EVA early aging, affecting components
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: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?
Classification of solar cells: Currently on the market of solar cells into amorphous silicon and crystalline silicon. Crystalline silicon can be divided into polysilicon and monocrystalline silicon. From the photoelectric conversion efficiency of the three materials is: monocrystalline silicon (up to 17%)> polysilicon (12 ~ 15%)> amorphous silicon (about 5%).
