- JA Solar‘s flagship n-type module, DeepBlue 4.0 Pro, was awarded the “Overall Highest Achiever” distinction in the 2025 PV Module Index Report released by the Renewable Energy Test Center (RETC), marking JA Solar’s sixth consecutive year to receive this top-tier honour.
- JA Solar also recently launched JA Solar Power Talk, a new global webinar series for expert dialogue on the future of solar energy.
- As extreme weather events intensify, PV systems face growing risks that threaten long-term reliability and investment returns.
- The inaugural episode, “How Your Modules Can Survive Extreme Weather,” convened leading voices from R&D, materials, and certification to explore how the industry is responding to these challenges.
Held on June 30, the session examined how PV modules can maintain durable performance in harsh environments such as deserts, coastal zones, and high-altitude regions. Panellists shared insights on scenario-based product design, advanced testing methods, and material innovations that are shaping the next generation of climate-resilient solar solutions.
Dr. Helen Zhou, Head of Module R&D at JA Solar, emphasised that while the industry pursues lower levelised cost of electricity (LCOE), performance gains must not come at the expense of cost-effectiveness. She noted that quality remains the top priority, and achieving the right balance is both a technical and strategic challenge. Rather than over designing for universal use, JA Solar focusses on developing scenario-specific products, optimising each solution for its intended environment to ensure reliability, efficiency, and economic viability.
Mr. Roger Miao, General Manager of PV at TÜV NORD China, provided insights into how the testing body is addressing the evolving demands beyond conventional certification frameworks. He outlined TÜV NORD’s advanced testing approach, which includes field simulations in desert conditions, sand abrasion assessments, and structural validation using wind tunnels and finite element modelling. He also reaffirmed TÜV’s commitment to working with manufacturers to close the gap between standards and application realities.
Ms. Betty Zhu, Vice President and Co-founder of Jiangsu Worldlight New Material Co., Ltd., introduced composite frame technologies designed to offer better performance than aluminium in extreme conditions. She explained how material innovations developed in collaboration with partners such as BASF offer superior mechanical strength, UV resistance, and salt corrosion protection. She also underscored the importance of supply chain localisation and long-term product validation to help mitigate the trade-offs that can arise under cost constraints.
The event concluded with a forward-looking dialogue on the future of solar in a changing climate. Panellists emphasised the importance of cross-sector collaboration, the growing role of meteorological data in project planning, and the need for tailored module solutions that address specific environmental challenges.
Building on this momentum, JA Solar Power Talk will be a global, scenario-driven webinar series that unites voices across the PV and energy storage value chain. By spotlighting frontier technologies, policy developments, and multi-scenario applications, the series aims to foster meaningful knowledge exchange and accelerate the industry’s transition toward high-efficiency, resilient, and sustainable energy solutions.
A recording of the inaugural episode is now available on JA Solar’s official YouTube channel. To stay informed about upcoming sessions, follow JA Solar on LinkedIn and Facebook.
JA Solar has again recognised for excellence in product quality, performance, and reliability. The company’s flagship n-type module, DeepBlue 4.0 Pro, was awarded the “Overall Highest Achiever” distinction in the 2025 PV Module Index Report released by the Renewable Energy Test Center (RETC), marking JA Solar’s sixth consecutive year to receive this top-tier honour.
The annual report, issued by U.S.-based RETC, is one of the most trusted benchmarks in the PV industry. The report evaluates PV modules from global manufacturers using rigorous testing protocols that go beyond standard IEC certification requirements. Only modules demonstrating consistently strong performance across all key indicators—quality, performance, and reliability—earn the “Overall Highest Achiever” title. In the 2025 assessment, only 13% of all tested products met this standard.
JA Solar’s 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—more than any other brand in this year’s evaluation. These results underscore DeepBlue’s all-round strength in long-term durability and power output, particularly under extreme environmental conditions.
The RETC recognition follows closely on the heels of another international validation: JA Solar’s DeepBlue 4.0 Pro was named a “Top Performer” in the 2025 PV Module Reliability Scorecard published by PVEL, another globally respected independent testing lab.
