JA Solar, a prominent player in the global green energy sector, has unveiled the industry’s first comprehensive white paper focused on photovoltaic (PV) solutions for desert, Gobi, and wasteland environments. This announcement came during a sideline event at the 21st China SoG Silicon and PV Power Conference on November 29, 2025. The white paper, developed in partnership with TÜV NORD, signifies a significant advancement in the field, combining JA Solar’s extensive experience with desert projects and TÜV NORD’s renowned testing and certification expertise.
The white paper addresses the unique challenges posed by extreme desert conditions, such as high ultraviolet (UV) exposure, frequent sandstorms, and sharp temperature fluctuations. It establishes a reliability testing framework that goes beyond traditional standards, offering clear guidelines for site selection, system design, and equipment choice. By moving the industry toward standardized approaches, the document aims to enhance the reliability of desert PV solutions and promote the adoption of innovative technologies.
At the heart of this initiative is JA Solar’s DesertBlue module, specifically engineered for arid and semi-arid regions. This module boasts an impressive output of up to 650 W and an efficiency rating of 24%. Notably, the DesertBlue features a nano-scale anti-dust coating that reduces transmittance degradation by over 32%, effectively extending its service life by three to five years. Its reinforced steel frame is designed to withstand up to 6000 Pa of front load and 4000 Pa of rear load, while an optimized thermal design enables up to 0.6% higher output in high-temperature conditions.
The module’s performance has been validated through extensive field testing. At JA Solar’s Shanghai Fengxian Base, the DesertBlue achieved a remarkable 7.09% increase in energy yield compared to conventional modules. Trials conducted in the Ulan Buh Desert demonstrated a 4.98% improvement in energy output, emphasizing the module’s exceptional reliability in harsh climates. Together with its reduced maintenance needs and lower operational costs, the DesertBlue solution significantly lowers the levelized cost of electricity (LCOE) for utility-scale projects.
The reliability testing framework outlined in the white paper has been independently validated by TÜV NORD. It encompasses various stress tests, including UV aging, thermal cycling, sand abrasion, hotspot endurance, and high-temperature mechanical loading. These assessments confirm that DesertBlue exceeds the International Electrotechnical Commission (IEC) requirements, ensuring its long-term performance in extreme desert climates.
“The release of this white paper reflects JA Solar’s commitment to scenario-based innovation and high-performance PV solutions,” stated Aiqing Yang, Executive President of JA Solar. “Our goal is to empower global partners with solutions that maximize energy yield, lower lifecycle costs, and ensure long-term reliability in the world’s toughest climates.”
