 FAQ

Q 1. what's the payment term?  

A. We accept TT,30% deposit and 70% balance agaisnt copy of BL

Q 2. how's the delivery time ?

A. usually it will take about 25 days for production

Q 3. tell me the standard of package?

A. For the small capacity, it use carton, but for big capacity, we will use strong wooden case for protection

Q 4. what kind of material of transformer?

A. we have two types, one 100% copper and the other is copper with aluminum.It depends on your requirment. In fact,those two have no difference if normal work well. Only except the longlife. Copper is better and also higer price. 

Q 5.Could you offer Form A or C/O ?  

A. It totally not a problem. We can prepare relative documents to forgin affairs office or other office to apply for this certificate.

Q 6.Would you accept to use our logo ?

A.If you have good quantity,it absolute no problem to do OEM.

Q 7.We want to know month capacity.  

A. It depends on which model.For example for relay type small capacity , month capacity can reach near 20000pcs   and big capacity near 3000pcs.

 Q 8.Where is your market?

A. Our products are popular in russia, indonisia, Philippines,italy, america, pakistan and so on.Some

 of them are our regular customers and some of them are developing. We hope you can join us and make mutural benifit from our cooperation.

Q:Can cold light make solar panels power
Solar power generation There are two ways of solar power generation, one is the light - heat - electricity conversion, the other is the optical - electrical direct conversion.
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 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:How many solar panels have ah?
But in reality, the need for solar panel power and solar charger to find a balance in the portability. It is generally believed that the minimum power of the solar charger can not be less than 0.75w, and the secondary power solar panel produces 140mA of current under standard light. In the general sunlight generated by the current at 100mA or so, if less than the secondary power charging current is too small,
Q:Why can not the solar panel load directly?
Solar panels because of low power, and the output voltage is extremely unstable, not suitable for load.
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: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:What is the principle of solar panels to convert solar energy into electricity?
When the light is irradiated on the surface of the solar cell, a part of the photon is absorbed by the silicon material; the energy of the photon is transferred to the silicon atom, so that the electrons are moved and the free electrons are formed on both sides of the P-N junction to form a potential difference. When the circuit is used, the current will flow through the external circuit to produce a certain output power. The essence of this process is the process of converting the energy of the photon into electrical energy.
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: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.
