JA Solar has again been recognized as a “Top Performer” in the 2025 PV Module Reliability Scorecard released by PV Evolution Labs (PVEL), the company’s DeepBlue 4.0 Pro module (model JAM66D45/LB) delivering outstanding results across multiple reliability test sequences and earning it the distinction for the tenth time.
PVEL’s Reliability Scorecard, based on its Product Qualification Program (PQP), is widely regarded as an industry benchmark. The program subjects PV modules to rigorous laboratory and field tests that simulate long-term operating conditions, thus helping buyers evaluate real-world durability and reliability.
“The fact that we were named a Top Performer by PVEL for the tenth time is both an honour and a responsibility,” commented Executive President Aiqing Yang. “It reflects our unwavering focus on quality and our drive to deliver reliable, high-efficiency products to global partners operating in increasingly diverse and challenging environments.”
The DeepBlue 4.0 Pro is already widely adopted across global markets, earning praise for its energy yield, long-term reliability and adaptability. Building on its success, JA has introduced application-specific solutions tailored to harsh climates—environments ranging from deserts to offshore to alpine to typhoon-prone regions—as well as specialized use cases such as anti-glare, lightweight and fire-resistant modules.
