Product Description


B Grade with 250w mono solar panel 

Specifications

High efficiency, B grade solar cell; 
elegant in appearance ; 
skillful in workmanship ; 
range from 5-310W

Products Performance 

* High powered modules providing solutions for variety of applications.

* All modules designed and manufactured in our ISO 9001 certified factory.

* Modules are UL 1703 safety rated for high wind pressure hail impacted,

snow load and fire.

* Integrated bypass diodes to protect the solar cell circuit from hot spots

During partial shadowing.

* Anodized aluminium frame mproves load resistance capabilities for heavy

Wind loads.

* Our module technology ensures there are no problems of water freezing and warping.

* Low power tolerance of +0~3% helps higher output power by reducing

module string mismatch losses.

* Monocystalline and Polycrystalline cell technologies with efficiencies up

to 17%.

* Highly transparent low-iron and tempered glass anti-reflective coating increases energy yield.

* New eco-friendly packaging minimizes cardboard waste and requires less transportation and storage space.
