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:Why dont we have a gigantic solar panel system in the warm states,stretching miles across to supply the usa?
This is a great idea, but there are some intrinsic difficulties with the theory: First, the average US household uses 27.4kWh of power per day= aprox. 0,000 kWh per year. Solar panels create kWh/m^2/day. Therefore you would need 27 m^2 (290 ft^2) of solar panels per household. Not only does that use a lot of space, but it would also cost a fortune. We also have to take into account that the government does not want us to become dependent of oil for many reasons. Therefore it is unlikely the government would ever consider paying for it. Lastly, for power grids to stay functional at all times, backup power plants must be kept 'hot', to replace solar power stations as they stop producing. There is an energy cost to keep plants 'hot', which includes (in the case of coal plants) the burning of coal. Unfortunately, if the country is not willing to accept brownouts, the carbon footprint of any large scale solar project will have to accept the 'hot' non-producing power plants carbon emissions as their own. The continued advances in the ability to store electricity will greatly impact the successful implementation of a large scale solar power station being, carbon footprint free. However, it would be possible for every household to have their own solar panels. Since they would need about 290 ft^2 (or 5ft x 5ft), then it does seem reasonable that they could have this much on their roof or land somewhere. Any additional energy you make from the solar panels you can sell back to the power plants and make money. They could then use this extra energy to cover in brown out situations, etc. In order for this to work though, we would all need to be responsible for purchasing and installing our own solar panels. It would be nice if the government would offer greater incentives to do so.
Q:Question about using solar panels?
If okorder.com and they ship across the US and Canada.
Q:Everything about Solar Panels?!?
The okorder.com to find the info there.
Q:what is the best way to go solar?
is your place has enough wind or sunshine ? the turbine is not easily for maintenance. the solar panel is more stable, one broken panel willl not affect the whole system much
Q:How to select solar panel for this application?
First, you need to make sure that your battery can take a regular 34Ah discharge without damage. The usual wisdom when using deep cycle lead-acid batteries is to allow for no greater than 50% discharge. This is to prevent the battery from ageing prematurely. Note that automotive batteries are not usually considered suitable for deep-cycle applications. Best allow for at least 200Ah capacity. Your solar panel capacity needs to take into account that whatever the nameplate output of the panel, that will be what it will produce under ideal conditions, actual output will always be less, often quite a bit less. You also need to allow capacity to cope with dull, overcast days when the light level is very low. You can get solar maps that will give you the sunshine hours and irradiation levels at your location. The solar panel capacity ends up being a juggling act between available funds/space and how critical it is that the light always works as desired. Let's say you had a 400W panel, which sounds quite generous. In the middle of winter, it may produce only 75W for 5 hours on a dull day, not quite enough to run the light for 0 hours. Would you expect several such days in a row? How many days could a 00Ah of battery capacity cover under these conditions?
Q:When I make a solar panel what kind...?
You can make your own solar and wind power for less than $200. You can your power bill by making your own solar panels. You can save thousands of dollars and go green at the same time. 93.9% of the energy that is consumed by US is NOT from renewable sources. The best choices when it comes to home power are solar and wind power. These count for only 0.2% of the energy that is consumed. You can generate your own energy and send it on the power grids. If you don't use all the energy you produce the power company will pay you.
Q:is it worth it to install solar panels?
In the state of Pennsylvania in the USA, a very basic 5KW solar installation will cost you $35,000. Of that you will recover approximately $28,000 over the next five (5) years between the State and the Feds. Making your net-cost something between $7,000 and $9,000 depending on various factors. All other things being equal in a standard household with fuel-based heat and window units vs. central AC, this system will provide roughly 50% of power required with a payback of approximately eight (8) years (with electricity at $0.4/kwh). The system has an estimated forty (40) year service life. Without _all_ the subsidies, the payback is longer than the estimated system life, especially if you consider the time-value of money. The life-cycle cost of a photo-voltaic array is horrendous. By that, I mean the total cost of producing the panels, installing them, and then removing them and disposing of them in an environmentally correct manner. All that added in and there is a negative payback. So, it all depends on what one defines as worth it. Putting the cost onto taxpayers via governmental subsidy to make an otherwise wretchedly expensive process viable may give you all sorts of warm-and-fuzzy feelings about renewable resources and reducing dependence on foreign oil and so forth. But the reality is that the true cost of solar panels exceeds that of nuclear power per KW delivered. Even today when nuclear plants start in the Billions-with-a-B in any currency you would care to name.
Q:Solar Panel and Wind Power?
I live in the Southwest where the sun shines almost every day. I got a quote for Solar system to produce about enough to cover my annual usage. My annual average electrical usage costs about $2300, or about $90/MO. The system costs around $30,000 but I can get rebates and some of your tax dollars in subsidies to bring my cost down to under $20,000. I can borrow $20,000 for 3 years at 7% and pay $95/MO, so in 3 years I will have the system paid for. As you can see, I don't start Saving any money for a long time. Maybe the rates will go up in later years which will help, but My friends that have solar systems tell me things like controllers go bad over time and they cost like $3000. Will it ever pay for itself? Maybe. Please note. This still does not get me off the grid. This system will not support things like an electric stove, air conditioning, Pool pump running, etc. so I still need the grid for when these operate and my usage peaks. If I installed a system that would totally support everything 24/7 the cost would be astronomical. If you live in the east, midwest, or NW where you have cloudy days, your economic calculations will be much less favorable I would think, unless your power costs are much higher than mine..
Q:what are bad things about solar panels?
They're really expensive. If you want it for practical use like a house or car powering system. They're bigger than like a battery if you're comparing size to power. Like a car battery can produce more energy than a 6 x 4 panel (just an example)
Q:Please explain KW Solar Panels. What does it mean.?
It means that it will produce (at best) 5kW when the sun is shining in an ideal position, in hour that's 5kWh so, on a good summer day it may produce a total of 25kWh nothing at night see the link for a 5kW system, you need at least 0 possibly 20 times that.
