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.
