JA Solar has again been recognized as an ‘Overall Highest Achiever’ by US based RETC in its 2025 PV Module Index Report, based on the performance of the company’s flagship n-type DeepBlue 4.0 Pro module in testing.
Only modules demonstrating consistently strong performance across the key indicators of quality, performance and reliability earn the award, with only 13% of all products tested this year meeting the required standard.
The DeepBlue 4.0 Pro module stood out in 12 individual test categories, most notably damp heat (DH), potential-induced degradation (PID), ultraviolet-induced degradation (UVID) and efficiency, underscoring its all-round strength in long-term durability and power output, particularly under extreme environmental conditions.
“Our long-standing commitment to delivering high-quality, high-reliability modules stems from a focus on creating real value for our customers,” commented Executive President Aiqing Yang. “These repeated recognitions from authoritative bodies such as RETC affirm the strength of our technology and reinforce customer trust in our products worldwide.”
