Innovation is the core engine driving the development of the photovoltaic industry. Yingfa Ruineng has always been driven by technological research and development, carrying out effective innovative practices in the photovoltaic field. As of May 2025, the company has accumulated over 174 patent and software copyright applications. With its strong R&D capabilities, it has repeatedly set new technological benchmarks in battery conversion efficiency. Its independently developed N-type technology route TOPCon battery has achieved a certified efficiency of 27.02%. Through innovations such as the design of multi-layer dielectric passivation films and low-contact resistance metallization technology, the company has made breakthroughs in both efficiency and reliability. In addition, the company's BC battery, with its revolutionary "back-contact" structural design, achieves zero shading on the front, resulting in ultra-high conversion efficiency, an aesthetically pleasing appearance, and excellent low-light power generation performance. It is an ideal choice for the high-end distributed photovoltaic and BIPV markets.
Incoming Inspection:
Based on standards, raw materials are subject to incoming inspection. For materials with quality issues, a root cause analysis is conducted, and the abnormalities are reported. Inspection methods are continuously improved, and raw material inspection specifications are refined to enhance inspection capabilities. Additionally, periodic evaluations and annual qualification confirmations are conducted for suppliers. Quality information within the jurisdiction is organized and fed back, and quality analysis meetings are held with relevant departments.
01.Team Collaboration Skills
02.Deep understanding of standards.
03.Accurate risk identification ability.
04.Rich communication experience
Process control:
In accordance with the "Quality Control Plan," products are tested in four stages during the production process: self-inspection, first article inspection, process inspection, and final inspection, to ensure the quality of the products throughout the process. For non-conforming products found during incoming material inspection, production process inspection, and outgoing shipment inspection, the "Non-Conforming Product Control Procedure" is followed for handling.
