FAQ

1.Price per watt?

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

2.Parameter of the module?

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

3.Can you provide the peripheral products of the solar panels, such as the battery, controller etc.?

We have two companies(CNBM International & CNBM engineering Co.) with different approaches. We can supply not only the solar module but also Solar Cells, off grid solar system, even service with on grid plant.

4.Warranty policy?

Our product performance guarantees for 25 years

• 12 years guarantee for workmanship

• Timeliness of delivery

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

5.Lead time?

In 3 days after purchasing, we will arrange the factory delivery ASAP. The specific time of receiving is related to the state and position of customers. Commonly 7 to 10 working days can be served.

Q:Home made solar panel?
Building your own panels can be an interesting experiment, but if you are looking for solar panels to provide significant, consistent output, you should buy factory made ones. I get lots of calls from people who built their own panels and get a fraction of the advertised output from them. Plus, factory built panels will last 40 - 50 years, with a 25 year warranty, how sure are you that you can build something that can withstand the outdoors for that long? The price of panels has dropped a lot this year, plus with rebates and tax credits, it's getting more affordable.
Q:Why can not the solar panel load directly?
Solar panels because of low power, and the output voltage is extremely unstable, not suitable for load.
Q:How does a solar panel charge controller work for batteries?
The battery is probably 2v 7amp-hour, not 7 amp. 7amp-hour is basically just how big the battery is. You can charge that battery with as little current as you want, it'll just take longer. The 7 amp-hour tells you that it'll take a long time to charge. 7 amp-hour means it can discharge 7 amps for hour. If you were charging it at 7 amps, it would take hours to charge, but I don't recommend that. You could charge it at .5 amps for 4 hours or .25 amps for 28 hours. The smaller the current, the longer it will take, but it will get there eventually assuming your voltage is high enough (which it should be with the charge controller).
Q:Solar panel charging question?

Q:Hey. I need some help with solar panels and batteries :) Please see the detailed version beneeth :)?
One lithium cell requires 4.2V to obtain its full charge, Never exceed 4.2V ! Output from solar panel if below 3.7V , nothing charge to lithium. Total charging time until the cell is full depending on the AH rate of cell and the charging current that solar panel can be provided. Suppose cell is rate 5AH, and the charging current from solar panel under full sun shine can maintain 0.5A ( use solar panel short circuit current rate from its specification as a reference ) , hence, 0 hours is enough. And be sure the solar panel can maintain 4.2V output at 0.5A . Remember, over charge lithium cell one time might reduce its life into half . Therefore, let the solar panel output passing through a precision regulator to maintain output is 4.2V is the best way, because, as cell reaches 4.2V , no more charging current is forced into cell ( automatic stop charging ). If you do not have the knowledge to make this simple variable voltage regulator with LM37K ( if you choose this way, buy solar panel output has at least 2V) , you may choose to do it manually by install a current meter and a variable resistor in series between the panel output to cell. By adjust the value of resistor, charging current can be controlled ( if you choose this way, buy solar panel output has as less as 6V ). Count the charging time with a clock and adjust the charging current from time to time to maintain 0.5A .
Q:Can pluto recieve energy from solar panels?
Yes. Not practical, but possible. Solar cells actually work best at low temperatures. At a little under W/m^2, it'd take a large solar panel to generate enough power for a TV (several tens to hundreds of Watts are needed). And, no offense meant, what TV programs do you think you'll be watching? You sound kind of stupid....
Q:How do you make a solar panel?
It's pretty basic, but I hope this helps!
Q:How many and what size solar panels would I need?
Solar okorder.com in their survival discussion in the archive, this exact project was discussed at length.
Q:What if anything has been done to channel light power other than solar panels?
Crikey yes, all these terms should be googleable Solar chimney Solar cooker Passive solar Solar trough Solar water heating Double glazing I'm sure there are more, I thought clothes lines were powered by the wind?
Q:Do grid-tied solar panel systems have to be installed professionally?
