BEIJING, Nov. 29, 2025 — JA Solar, a respected global provider in green energy, unveiled the sector’s inaugural Desert-Gobi-Wasteland PV Solution White Paper during a parallel event at the 21st China SoG Silicon and PV Power Conference (CSPV). Developed collaboratively with TÜV NORD, this document marks a significant achievement, combining JA Solar’s extensive experience with desert projects and profound understanding of client needs with TÜV NORD’s globally recognized proficiency in testing and certification.

By scrutinizing the severe conditions of desert, Gobi, and wasteland environments—such as intense UV radiation, sandstorms, and drastic temperature fluctuations—the white paper establishes a reliability testing framework that goes beyond conventional benchmarks. It offers clear directives for site selection, system architecture, and equipment choices, guiding the industry from reliance on empirical knowledge towards standardized, methodical approaches. This foundation enhances the deployment of dependable desert PV solutions and supports the worldwide adoption of emerging technologies and future standards.

Central to the white paper is JA Solar’s DesertBlue module, engineered specifically for desert and semi-arid regions. Delivering up to 650 W output and 24% efficiency, DesertBlue features a nano-scale anti-dust coating that diminishes transmittance degradation by over 32%, thereby extending its operational lifespan by three to five years. Its reinforced steel frame withstands front loads of 6000 Pa and rear loads of 4000 Pa, while its optimized thermal design yields up to 0.6% higher output in elevated temperature conditions. Field observations further indicate DesertBlue operating nearly 5°C cooler in dusty environments, emphasizing its dependability in extreme climates.

Outdoor empirical evaluations confirm DesertBlue’s superior performance. At JA Solar’s Shanghai Fengxian Base, the module achieved a 7.09% increase in energy yield, while pilot projects in the Ulan Buh Desert demonstrated a 4.98% improvement compared to standard modules. Coupled with reduced cleaning requirements and lower robotic O&M expenses, this solution provides substantial lifecycle savings and contributes to a lower LCOE for utility-scale developments.

In addition to field validation, the reliability framework—independently verified by TÜV NORD—encompasses UV aging, thermal cycling, sand abrasion, hotspot endurance, and high-temperature mechanical stress. These outcomes demonstrate DesertBlue’s resilience under conditions that surpass IEC specifications, reinforcing its sustained performance in severe desert climates.

“The publication of this white paper highlights JA Solar’s dedication to innovative, scenario-specific, and high-performance PV solutions,” commented Aiqing Yang, Executive President of JA Solar. “Our objective is to equip our global collaborators with solutions that optimize energy output, reduce lifetime expenditures, and guarantee enduring reliability in the planet’s most challenging environments.”
