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 Solar Cells, 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.

 One of the things to be aware of if you are a bit of a handyman and want to build your own solar panel is the efficiency of the solar cell. This is important because, although you can, link up several solar cells to build your own solar panel at a fraction of the cost of commercial panels relatively easily, you will need to invest in solar cells.
Now, what we are doing here is two things, primarily we are wanting to cut our electricity bills by installing solar panels. The second object is to save money by doing it ourselves. Now this is where the efficiency of the solar cells are important.  We need to balance cost against efficiency if we really want to save money because it is the final cost of your homes solar energy system that matters.
OK, right now you are probably think, yeah, well of course, the better the solar cells I install, the more efficient the system will be and the more money I will save. And you would be wrong.
We have talked about the different ways of producing solar cells in other articles, but in simple terms, there are two types we will look at here. Polycrystalline and mono crysalline.
Polycrystalline cells are build from small, multiple slices of silicon, whereas mono crystalline cells are built from one, larger slice. The later cells are certainly more efficient, a poly cell is rated  somewhere between 16% and 20% efficient, a mono cell can be rated around 30% efficiency level. Logic would dictate that we should build our own panels with 30% efficiency panels. But wait a moment.
Mono crystalline panels are more complex to manufacture, their cost can, be several times more than polycrystalline. Ahh, now maybe the maths start to tumble into place, we are gaining a 10% increase in generation but at what cost?  It may well be that we are not actually saving money at all.
So this is what we mean when we say you need to look past the sales talk and hype and balance the efficiency of the solar cell you are thinking of against the total cost to work out if it is economical or not.
