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: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 working principle of solar panels?
the inorganic salts such as gallium arsenide Ⅲ-Ⅴ compounds, cadmium sulfide, copper indium selenium and other multi-compounds as the material of the battery;
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: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 difference between solar panels and light panels?
Silicon solar cells are divided into monocrystalline silicon, polysilicon, amorphous silicon, silicon thin film solar cells and several. At present, the world's most widely used solar cells are silicon solar cells, in large-scale applications and industrial production is still dominated by the penetration rate of 90% or more, monocrystalline silicon solar cell photoelectric conversion efficiency of the highest technology is also the most mature.
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 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 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.
