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.
