JA Solar Wins RETC “Overall Highest Achiever” Award for the Sixth Year in a Row

JA Solar, a global leader in high-performance photovoltaic technology, has once again earned top recognition for its outstanding product quality and reliability. The company’s flagship n-type module, DeepBlue 4.0 Pro, was awarded the prestigious “Overall Highest Achiever” title in the 2025 PV Module Index Report published by the Renewable Energy Test Center (RETC) — marking an unprecedented sixth consecutive win.

The RETC report is widely regarded as one of the most trusted and rigorous benchmarks in the PV industry. Its annual evaluation process goes beyond standard IEC certifications, using advanced stress testing to assess long-term durability, efficiency, and reliability across multiple performance indicators. In the 2025 edition, only 13% of all tested modules achieved the “Overall Highest Achiever” distinction — placing JA Solar’s DeepBlue 4.0 Pro firmly at the forefront of global PV excellence.

🔬 DeepBlue 4.0 Pro: Engineered for Durability and Efficiency

JA Solar’s DeepBlue 4.0 Pro module excelled in 12 test categories, including high-performance benchmarks such as:

• Damp Heat (DH)

• Potential-Induced Degradation (PID)

• Ultraviolet-Induced Degradation (UVID)

• Energy Efficiency and Output Stability

These results underscore the module’s exceptional performance in real-world conditions — particularly in harsh environments where durability and long-term energy yield are mission-critical.

The module’s recognition by RETC follows another major industry endorsement: DeepBlue 4.0 Pro was also named a “Top Performer” in the 2025 PV Module Reliability Scorecard by PVEL, further validating its position as one of the most reliable modules on the market.
