Product Description:

Our company engaged in development,research,production ,sales and service of cyystalline ,solar panels and power plants.

Since the inception in 2008,our products have obtained the certifications of TUV,CE,MCS,CQC,CEC,UL,etc.And we supply products to more than 60 countries and regions,such as Germany,Spain,Italy,America,Japan.India,China and so on.

Our company has strong technical and financial strength and we have 5 divisions: Solar Energy Photovoltaic Research Institute, Crystalline Silicon Wafers Division, Solar Cells Division, Solar Power Panels Division, and Photovoltaic Power Generation Systems Engineering Division.

Based on the fundamental research and application of the leading technology in the photovoltaic industry, we keep on enhancing our science and technology and cooperating with domestic and international research institutes to provide strong talent reservation and technical support for the fast development of photovoltaic industry in our country. The research institute has consisted by three research centers: Research Center on Solar Cells, Research Center on PV Components and Research Center on PV System Integration & Application Technology; meanwhile a Management Center has been set up to best realize our management and service.

In every department there are many professional engineers and administrators. By great investment in technical research and product design, we guarantee the best quality of our products, and gradually reduce the cost on solar photovoltaic power generation, and realize our target: let Chinaland Solar Energy power generation products to be widely used in every family all over the world.

Our solar panels are widely used in commercial,residential and industrial solar power systems (on-grid & off-grid),PV power station and many other different regions.

Q:What is the principle of solar panels work?
optical - electrical direct conversion method is the use of photoelectric effect, the solar radiation can be directly converted into electrical energy, optical - electrical conversion of the basic device is the solar cell. The solar cell is a device that converts solar energy directly into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When the sun shines on the photodiode, the photodiode turns the solar energy into electricity. Current. When many batteries in series or in parallel can become a relatively large output power of the solar cell array
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 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: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
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: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:Composition and function of solar panels
Among them, for the electronic grade polysilicon accounted for about 55%, solar grade polysilicon accounted for 45%, with the rapid development of photovoltaic industry, solar cell demand for polysilicon growth rate higher than the development of semiconductor polysilicon, is expected to 2008 solar polysilicon
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.
