FAQ

We have organized several common questions for our clientsmay 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:Need help with Solar Panels (FAQ's and opinions)?
Also crystalline silicon, but almost triple the power. I would suggest that you have a lot more research to do before just buying a panel. A single panel like that isn't immediately useful unless you have a device that takes exactly that voltage, and is not critical. A solar water pump might fall into that category. For anything else, you would need additional equipment, such as a battery, charger, and inverter. Even at these prices, a single panel is unlikely to save you money over the electric company in the long run, unless your electricity is very expensive. There is economy of scale, so larger systems can and do save money, at least for people located in the right place. If you have a remote cabin where there is no electric company, then this could be worth it.
Q:How may solar panels/wind turbines may be made affordable?
Answered okorder.com/. They were initally so lame (and this is related to their general paranoia) that they cut deals to place the turbines before they secured corridor access to substations. Load gun, cock it, aim at foot, shoot.
Q:Can you connect a solar panel to a regular plug, using copper wire?
Leave the two positive terminals connected together.Disconnect the negative leads from each other. Get two amp diodes from radio shack. Connect each diode in series with each negative lead. there is a band on one end of the diode. Connect each diode so that the end with the band is attached to the negative side of each solar panel. Tie the other ends of the diodes together. This will become the new negative end of your solar panel supply. With the sun shining on the panels , you will now measure the voltage from the plus side of the solar panels to the new negative junction. Connect your load leds in place of the voltmeter and enjoy. Without the diodes , each solar cell thinks the other solar cell is the load. In effect each solar panel is shorting out the other. Some solar panels that you buy already have a diode in their junction box connected for that purpose. You need the diodes to provide the necessary isolation between the two panels, then they can both act in parallel to provide current to the load.
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:Reflectors or mirrors around the solar panels.......?
You could (an example of concentrating sunlight is called cloud gain, where the edge of a cloud will intensify sunlight as it passes between the sun and your panels), but that will make your panels run hotter and will probably reduce their life. It's better from a system design standpoint to simply get another panel or two. DK
Q:How to wire solar panels?
I'll add a few comments to Teelo's It may not be good to connect the assembled solar cells directly to the battery. When there is no sun I think it will drain the battery. I'm pretty sure all circuits I have seen have a reverse polarity diode in series. (unless Teelo knows for sure). Hmmm Reminds me that I have some bare solar cell elements from when Motorola was making them. I used some to power a small radio controlled car. I do know that all good applications have a regulator to make sure the charging is done properly
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:What happens if I put a 00v, .5A solar panel on a 2V, 450cca Gel deep cycle battery?
yes not good.. why would put 00volts to a 2 volt battery? the best you can hope for is to destoy the battery 3.6v max do not excide max amp on battery
Q:should i get a solar panel?
Solar power works by capturing photons from the sun and storing their energy in a battery. Solar panels still only capture a very small amount of photons due to technology/distance from the sun/ and probably a number of other reasons. If you wanted to buy a solar panel, you find a company that sells them, send them your electric bill for the past year or so. They calculate the energy restraints, size and additional technical mumbo jumbo. They tell you how much it costs and how much money you could save. Some people might buy a size larger than what they need, in which case they sell the excess energy to your local power company for a few pennies a month(this is usually not very profitable).
Q:Life expectancy of LEDs and Solar panels...?
LEDs last approximately 50,000 hours of operation, continuous or non-continuous, it doesn't matter. 50,000 hours. Solar panels will, theoretically, last until the end of time. The support structures will fail long before the panels themselves. Inverters, battery banks, op-amps, transformers, control boards, etc. will all fail long before a solar panel stops making juice.
