JA Solar Pioneers PV Technology for Extreme Environments

In a significant advancement for renewable energy, JA Solar has unveiled the industry's first white paper on Desert-Gobi-Wasteland PV solutions. This initiative, showcased at the 21st China SoG Silicon and PV Power Conference (CSPV), marks a collaborative effort between JA Solar and TÜV NORD, a leader in testing and certification.

The white paper addresses the unique challenges presented by extreme environments, such as those found in the desert and Gobi landscapes. The document provides a new reliability testing framework that sets a higher standard for PV systems designed for these harsh conditions. By moving towards a systematic approach rather than relying solely on past experiences, this work aims to enhance the deployment of reliable solar technologies across drought-prone areas.

Central to this innovative paper is JA Solar's DesertBlue module, which has been specifically engineered for operation in arid climates. This module boasts an impressive output of up to 650W and achieves a remarkable efficiency rate of 24%. One of its most notable features is a nano-scale anti-dust coating that mitigates transmittance degradation by more than 32%, thereby extending the module's lifespan by approximately 3 to 5 years. Additionally, its robust steel frame can withstand substantial loads of 6000 Pa from the front and 4000 Pa from the back. With enhanced thermal management, DesertBlue is designed to perform optimally in high-temperature scenarios, achieving outputs up to 0.6% higher than conventional models.

Field tests that JA Solar conducted at its Shanghai Fengxian Base have demonstrated a significant 7.09% increase in energy yield with DesertBlue modules. The trials in the Ulan Buh Desert further validated this performance, showing a 4.98% improvement over traditional PV systems. Lower maintenance requirements, reduced cleaning efforts, and decreased operational costs lead to impressive lifecycle savings and a lowered Levelized Cost of Energy (LCOE) for utility-scale installations.

Moreover, the white paper’s reliability framework, which has received independent validation from TÜV NORD, assesses performance through various factors including UV aging, thermal cycling, sand abrasion, hotspot endurance, and mechanical loading under high temperatures. The findings reveal that DesertBlue modules surpass the IEC standards, thus ensuring longevity in the harsh conditions characteristic of desert climates.

Aiqing Yang, Executive President of JA Solar, expressed that the publication of this white paper underscores their commitment to innovative, scenario-based solutions and high-performance PV technologies. “Our mission is to empower our global partners with solutions that enhance energy output, reduce lifecycle costs, and guarantee sustained reliability in the harshest climates on the planet,” he stated.
