 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:question about solar panels....?
Not many people realise it, but Einstein did not win the Nobel Prize for either Theory of Relativity. He was awarded the prize for his work on the photoelectric effect. i.e. the ability of some materials to take photons of light and turn their energy into electricity. Now, since most of the Sun's UV rays are filtered out by the Earth's atmosphere, else we'd be able to get a sunburn in seconds walking around outside in daylight, I think there is some energy imparted to the solar cells by UV wavelengths of light, but most solar cell materials rely on the wavelengths of electromagnetic radiation we call visible. Plus, I always thought infrared wavelengths conveyed more heat energy than UV rays.
Q:Is there a free solar panel program for veterans?
It varies from state to state.
Q:Mono-crystalline or poly-crystalline solar panel?
All solar photovoltaics drop in efficiencies with higher temperatures but it isn't the 45+ C you have to worry about but rather the heat from the sunlight striking the panels. There are hybrid systems which passes water in pipes attached to the back of the solar panels to cool the panels and preheat the water for solar thermal collectors. The difference between mono-crystalline and poly-crystalline are that mono-crystalline are more efficient and more costly to make.
Q:The effect of colored light on a solar panel?
Likely there will be at least a small change in the no load volts. The short circuit current will be different and the watts output will be different. Connect an amp- meter to the panel with or without a to 00 ohm resistor in series with the amp-meter and you will see different amounts of current for different colors. You do however need to adjust for the amount of light falling on your solar panel. Possibly you can use a exposure meter or a bolo meter as reference. Neil
Q:What are solar panels made of?
photograph voltaic panels take power (and in all probability some oil for the plastic) to fabricate, yet that power, and the carbon footprint, is paid for many circumstances over in widespread operation, via the electrical powered energy that the panel generates. The life of the middle photograph voltaic cells is long (there are nonetheless some panels from the 970's that are nonetheless out and dealing), and contemporary panels are oftentimes warranted for 25 years, showing that even the manufacturers have self assurance in thier lifespan. yet whilst it ultimately comes time to eliminate the panels, the aluminum physique is as particularly recycled as the different aluminum, and the tempered, low-iron glass could properly be recycled, too. The plastic substrate is unavoidably solid - it has to stand up to the solar for some years. i do no longer understand what could desire to be achieved with that. The cells themselves are a intense grade of silicon, which has fee on the scrap industry. some panels are no longer made up of silicon - yet lots of the factors could desire to be recycled in a similar fashion. i'm no longer attentive to any intense panels being dumped or discarded at present. they're worth lots, even broken, that some hobbyist or surplus place will purchase them.
Q:What about solar panels?
This is a site that can help you estimate the size and number of panels that will power what you intend to provide for. There are plenty of sites selling the panels, so compare prices. Also, check whether your state is offering the rebate like the state of CA is and what the restrictions, terms and conditions are. Even with the rebates they are very costly, so be certain to calculate the pay off period for your application to see whether it is a cost efficient option for your energy usage.
Q:Infra-red solar panels?
No night vision takes star light and intensifies it by 30,000 times.
Q:Solar Powered Propeller?
Solar panels produce electricity. To move the propeller you need mechanical motion. An Electric motor converts from electrical to mechanical power. Most Solar Panels produce DC electricity as do batteries so you need a DC motor that is sized to match the Output of your solar panels. For small temporary projects like this I find that hot melt glue is great to assemble parts. Using a voltage meter you can expose your solar panels to a strong light (or one equal to what you expect during your demonstration) and measure the voltage across the terminals. This may help to size the motor. It depends upon the size of your propeller and how it is made. Your three choices are to use it to power an airplane, to power a boat underwater or to power a boat like an air boat. You might also use the air boat concept to make a car. (air car) The air boat might be the simplest to make but you will need a body of water to demonstrate the concept. The air car doesn't have such a requirement.
Q:does vibration affect solar panels?
clearly. if the panel is moved, its action will be distorted. it should be kept in a level, stable location to reduce likelihood of such events occuring.
Q:Solar Panel/Energy help?
The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions. A computer and monitor use about 400 Watts. not per hour - watts is Volts * Amps and a measure of Power. In hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 400 = 4000 Watts. To run this from solar panels through the day only you would need a 4000 Watt panel. Except - its cloudy, the sun is in the wrong place - many factors reduce the output. To be reasonably safe you would need about a 2000 Watt panel. Then you would need batteries to store power through dull periods AND a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.
