Solar Polycrystalline Series Panels

Introduction of Polycrystalline Solar Panels

We make solar power possible for communities everywhere by global manufacturer and logistical expertise to address unique energy challenges.As the world largest solar panel's manufacturer, our teams of local experts are enpowering around the world to go solar.


As the world confronts unprecedented and environmental chanllenges, we will commit to our mission : to provide affordable energy to the world.


Characteristics of Polycrystalline Solar Panels

I Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.

II Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.

III EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.

IV AI frame: Without screw, corner connection. 6 holes on the frame can be installed easily.

V Junction box: Multi function junction box with water proof.

VI Long lifetime: ≥25 years; Less power decrease

VII Good performance of preventing from atrocious weather such as wind and hails.

VIII Resisting moisture and etching effectively, not effected by geology.


Standard Test Conditions of Polycrystalline Solar Panels

The opto-electrical specifications shown below are stabilized values being measured at Standard Test Conditions, Irradiance: 1000W/m2, Spectrum: AM1.5 at 25°C, The info below is subject to manufacturing tolerances. Where appropriate minutes of measurement are available and are used for the dimensioning of the installation.

We have organized several common questions for our clientsmay help you sincerely


1.    What’s price per watt?

A: It’s depends on the quantity, delivery date and payment terms of the order. We can talk further about the detail price issue. Our products is high quality with lower price level.


2.    Can you tell me the parameter of your solar panels?

We have different series of cells with different power output, both from c-si to a-si. Please take our specification sheet for your reference.


3.    How 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.


4.    Can you do OEM for us?

Yes, we can. We can make the solar panels according to our customer's requirement such as attaching customer's logo, customized customer's dimension etc. 


5.    How long can we receive the product after purchase?

It need about 1-2 Month if transport  by sea.
