5.FAQ of Solar Module

We have organized several common questions for our clientsmay help you sincerely

what price for each watt?

it depends on the quantity, delivery date and payment terms,

what is your size for each module? can you tell me the parameter of your module?

we have different series of panels in different output, both c-si and a-si. please take the specification sheet for your reference.

Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other?

Yes, we can, we have two companies for solar region, one is CNBM International, the other is CNBM engineering Co.

We can provide you not only the solar module but also Solar Cells, the off grid solar system, we can also provide you service with on grid plant.

What is your warranty system?

 Our product  performance guarantees for 25 years

12 years guarantee for workmanship

Timeliness of delivery

Quality Products certified (TÜV, UL, CE, ISO)

How do you pack your products?

We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.

Q:solar panel design question?
Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.
Q:what do we mean by efficiency of a solar panel?
Sunlight power panels had been the go-to choice for many years. They are among the many oldest, most efficient and most liable methods to produce electrical energy from the solar. Every module is made out of a single silicon crystal, and is more efficient, although more pricey, than the more moderen and less expensive polycrystalline and thin-film PV panel technologies. You can normally appreciate them through their color which is more often than not black or iridescent blue. The silicon crystals have lengthy existence and they may be able to withstand wear and tear with out degrading its workability. Additionally solar is a main source renewable vigour as far as the sunlight method is worried. Sunlight has little influence within the residing creature. So sun panel should be in practice
Q:How can you get affordable Solar Panels?
you okorder.com. all you have to do is watch the video.
Q:how to power a 400 watt heater with solar panels and batteries?
Get the rating from the manufacturer, they will give you the watts per m2 of their panels. divide 400 into the rating and will have the total area, then get the area of the panel that physically fits better the project and divide the total area into that of the panel selected, you will have how many panels you need. For the batteries is more complicated because of the available light hours of your location and what time of day are you going to use the heater, to be safe make a bank of batteries to store 600 watts to have a 50% stored power for emergency
Q:how to make your own solar panels ?
It used to be possible to get broken solar cells for free from solar cell and solar panel manufacturers and then it's just a matter of labouriously measuring the voltage and current characteristics of each fragment and soldering them in a combination of parallel and in series to get a crude solar panel with the desired output but the manufacturers have caught on and now sell the broken fragments by the pound so it's not really a cheap solar panel anymore but it's still very labor intensive and results in a fragile solar panel that is readily damaged and quickly degrades. Not really worth the trouble any more.
Q:How much does it cost a factory to make a solar panel?

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:solar panel questions.....................?
No don't do that unless you want a fire or worse electricution . DO NOT PLUG INTO THE WALL . st solar panel 2nd regulator 3rd 2 volt battery 4th inverter . The inverter should have 0 volt terminals that look like the plug on the wall . You would plug your TV or light into that the inverter . You would need an electrition to hook into your home electrical system . They will hook up a device made to tie into the grid or your meter that will make it run backwards but it takes alot of solar panels too do that . Please do not plug into wall .
Q:so i'm wanting to eventually get solar panels.?
From a power company's perspective, it costs more to supply electricity during hours when electricity use is high. The times of day when power use is the highest are called peak hours. Historically power companies would sometimes charge large power users a higher rate during peak hours to encourage them to shift their electricity use to other times of the days. With the development of smart power meters and smart grid technology, it's now possible to offer the same incentive to individual home owners. so i'm wanting to eventually get solar panels.? If you live in an area where the electric rate varies depending on the time of day, then peak shaving improves your payback/return of investment on grid tied solar panels. Particularly in areas with high air conditioner usage, the peak hours generally correspond to the times when solar panels generate the maximum power. Look at it like this: Suppose your power company charges you $0.5/kWH during off peak hours and $0.30/kWH during peak hours. Because the solar panels generate the most power when the cost of electricity is the highest, it is easier to justify the cost of installing the panels because you are avoiding buying electricity at the highest rate. If your power company just bills you at a flat rate at all times, then it becomes more difficult to justify the cost of installing the panels and associated equipment..
Q:Solar panel trouble?
To test a solar panel, connect a voltmeter, and turn on and off a light. If the voltage increases when the light above the panel is on, it is working. The solar panel does convert solar (light) energy into usable (electrical) energy. No extra conversion is necessary to make eletricity. You might, however, want to convert .5 VDC or 2 VDC output of solar panel(s) - or the batteries they charge - to 20 VAC with an inverter though. If a capacitor is broken, it will look like an electrical short circuit all the time.
