Product Description

Solar Polycrystalline Series Panels

Introduction of our company

We are leading global provider of green energy technology and solutions. Since 2005, our company has earned a reputation for superior quality and production efficiency. The company has shipped millions of solar and lighting products to customers around the world, supported by more than 30 office locations in 16 countries.


Drawing on its deep heritage in solar technology, our company has deployed its expertise to the LED lighting sector. Through its exceptional manufacturing and sales channels, we produces and supplies a wide range of LED products to add value and meet ROI objectives for distributors’ clients across a number of sectors.


We are committed to produce development and quality control and all of our products comply with international quality standards. We are focused on constantly developing more efficient green energy products and optimizing our cost structure while maintaining technological leadership in our field. We has received numerous patents for new technologies and innovations, and our green energy products are well received by customers around the world.


Our R&D teams are constantly exploring new ways to improve photoelectric conversion efficiency and reduce manufacturing costs. One of our flagship products, the Virtus II Wafer, remains a technological leader in its field while actively optimizing the cost structure. Together with downstream enterprises, this ultimately reduces the total investment in solar photovoltaic systems, and thus greatly improves the overall rate of return on investment.


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.


Advantages of Polycrystalline Solar Panels

1.High reliability with guaranteed -3% to +5% power output tolerance, ensuring return on investment
