We enjoy exclusive channel to get stock solar panels at more competitive price from Trina,Hanwha,Yingli,LDK,Suntech etc.
These panels are from tier 1 solar panel manufacturers,such as Trina,Hanwha,Yingli,LDK.They are assembled with all grade A materials,only problem is that they has slight appearance defect,but due to their strict quality control,even the negligible defect will lower its grade.so they put these panels into stock.
These panels adopt all grade A materials,such as solar cell,EVA, back sheet, junction box, glass,frame,connector etc.
They have same electrical performance with grade A solar panels,only difference is the negligible superficial defect.

- Q:Why can not the solar panel load directly?
- Solar panels (also known as solar modules) are the core of solar power systems and the most important part of solar power systems.
- 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?
- 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 principle of solar panels to convert solar energy into electricity?
- Silicon" is one of the most abundant materials on our planet, and since the nineteenth century scientists have discovered the semiconducting properties of crystalline silicon, it almost changed everything and even human thought. At the end of the 20th century, our lives were everywhere Crystal production and process can be divided into five steps: a, purification process b, drawing process c, slicing process d, the system of silicon Battery process e, packaging process.
- 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:Can solar panels be connected directly to motor?
- 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
- Used to bond fixed tempered glass and power generation (battery), transparent EVA material directly affect the quality of the component life, exposure to the air in the EVA easily aging yellow, thus affecting the component's light transmittance, thus affecting the components
- Q:Polycrystalline solar panels are good or single crystal solar energy is good
- 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% (
- 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,
