회사 설명

Founded in 1999, Topray Solar Group is a professional solar manufacturer with over 20 years of rich experience. As a stock exchange company, Topray Solar Group has six factories in different parts of China, producing in different sectors of the solar value chain.

* Solar glass: 7 GW

* EVA: 5 GW

* solar cell

* solar panel (on grid + off-grid): 2 GW

* solar wafer

The above-mentioned vertical-integrated abilities enable us to resist the risks of short supply of materials, late delivery, and big price fluctuation, which happen from time to time in the solar industry.

With our supply chain advantage, we will be able to provide a better and one-stop service to our customers (supply glass + EVA as a package, and OEM solar panel manufacturing) and be more flexible when doing business.

Our solar panel has all the required certifications from around the world: IEC, UL, BIS, INMETRO, CEC, etc.

Our solar glass and EVA are supplied to world-class solar panel manufacturers both domestically and abroad.

Topray Solar is awarded as a national-level high-tech enterprise, and 3-4% of sales turnover is re-invested into R&D. Up till now we have obtained 583 patents, including 56 invention patents.

Topray Solar is also a PV project developer, investing in a solar power plant of our own with over 700 MW capacity, and more projects are in the pipeline.


Featured Product

• The transmittance of our coated solar glass is over 94%.

• Proprietary 800°C online coating technology.

• Anti-aging, acid-resistant, anti-fog, and abrasion-resistant.

• Topray solar glass is a low-iron, rolled product formed with a pattern on one surface. The pattern provides the desired obscurity while retaining high transmission values.

• It is the best for making PV modules and solar flat collectors.

Application of our Solar Glass

• Our coated solar glass can improve the output power of the solar module by at least 3.5%.

• Solar modules that are integrated with our solar glass withstand high levels of wind loads (2400Pa) and snow loads (5400Pa).

• Anti-reflective, hydrophobic layer of solar module surface improves light absorption and reduces surface dust.

• Solar flat collector withstands high pressure - bearing up to 0.9MPa.

• All our solar collectors are with coated PV Glass, and the light transmittance rate reaches 95%, which can guarantee 2-3% more overall yield compared to conventional collectors.

• Anti-reflective, hydrophobic layer of solar module surface improves light absorption and reduces surface dust.
