Product Description
B Grade with 250w mono solar panel
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.
