FAQ

We have organized several common questions for our clients，may help you sincerely：

①What price for each watt?

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

②What 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.

③Can 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 the off grid solar system, we can also provide you service with on grid plant.

④What 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)

⑤How 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.

⑥ Can you do OEM for us?

Yes, we can.

⑦How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The pecific time of receiving is related to the state and position of customers.Commonly 7 to 10 working days can be served.

Q:Is there such a thing as portable solar panels? Can these be obtained for say a mobile homes / caravans etc.: There are RV solar panels but they are mostly for extending the life of the batteries, you should still bring a generator. There are marine solar panels and wind turbines which are larger but many sailing yachts are larger too.

Q:I have the wattage of solar panel but i dont know about the voltage amp; current rating of it. Plz explain me about the voltage rating of solar panel.: A okorder /

Q:when we say a solar panel has 20% efficiency, do we mean that it converts 20% of sunlight reaching it into electricity or that it converts 20% of visible light(which is only 7% of sunlight) into electricity?: 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 would you build a solar panel: As a sandwich. Glass Space /4 inch Glass Space with copper radiator painted flat black. Box made of wood. with the inside painted black. Insulate the back side. Use water with RV antifreese. Circulate water through with a small pump. Face it toward the sun. Thermal water solar Panel.

Q:I have a solar panel, charge regulator, inverter....is that all I need to tie it into my grid? Do I just plug the solar panel into the charge regulator into the inverter into any 0v outlet? I feel like im missing something....: 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:Can anyone tell me how to connect a solar panel from a calculator to a motor from an RC car.: Connecting them is not a problem: the solar cell has two leads or terminals, and so does the motor. The problem is that the panel from the calculator cannot supply very much current, and you need quite a bit for the motor. Also, the voltage is probably not more than 3 volts, and the motor needs probably six to twelve volts. If you have a voltmeter, check the output from the solar cell. You can get solar cells that will put out more current, but they will be bigger than the ones used for calculators. Even with these, you will probably need several in series to get enough voltage for the motor.

Q:Say if i had a 2KW system is thtat just one big solar panel or does the whole system have little solarpanels together.?: Solar panels are arrays of individual solar cells connected in series and parallel, and.. A high quality, monocrystalline silicon solar cell, at 25 °C cell temperature, may produce 0.60 volts open-circuit (Voc). The cell temperature in full sunlight, even with 25 °C air temperature, will probably be close to 45 °C, reducing the open-circuit voltage to 0.55 volts per cell. The voltage drops modestly, with this type of cell, until the short-circuit current is approached (Isc).

Q:Can solar panels be used for charging outdoor power tools?: Yes, solar panels can be used for charging outdoor power tools. Solar panels convert sunlight into electricity, which can be used to power various devices, including outdoor power tools such as lawnmowers, trimmers, and chainsaws. This provides a sustainable and environmentally-friendly alternative to traditional methods of charging these tools.

Q:I want to get solar panels but not spend 20,000!! I found out that you can get a panel to run only your AC unit, I also found something that will run my pool pump! Anyone own either of these? How did you do? Where did you go? How much was it, and was it hard to install?: Most major cities have construction signs and other public things powered by solar panels. We have parking meter stands, USGS meters, street lights, etc. when these lose efficiency, they need to be replaced. They still work at about 60 percent efficiency. Learn who services these items and ask how to get them at a reduced rate or even for free. Be personable and nice and go to the source physically, not via e-mail. You can get a solar panel to run just about anything

Q:Can solar panels be used to power a swimming pool?: Yes, solar panels can be used to power a swimming pool. Solar panels can generate electricity from sunlight, which can be used to power pool pumps, heaters, and other equipment required for pool maintenance and operation.
