## Overview
JA Solar has announced the release of what it calls the industry's first Desert-Gobi-Wasteland PV Solution White Paper, presented during a side event at the 21st China SoG Silicon and PV Power Conference in Beijing. The document focuses on photovoltaic (PV) system performance and reliability in harsh desert, Gobi, and wasteland environments.
## Collaboration and Purpose
The white paper was jointly developed by JA Solar and TÜV NORD, combining extensive desert project experience with an internationally recognized testing and certification methodology. Its goal is to guide the industry toward standardized, scenario-based PV design and deployment in extreme climates rather than relying solely on empirical experience.
## Harsh Environment Challenges
The study examines environmental stress factors typical for deserts, including intense ultraviolet radiation, frequent sandstorms, dust accumulation, and strong temperature fluctuations between day and night. These conditions accelerate component aging and can significantly reduce energy yield if not addressed with dedicated system design and materials.
## Testing Framework and Standards
The white paper introduces an enhanced reliability testing framework that goes beyond conventional IEC requirements for PV modules used in standard climates. This framework covers UV aging, thermal cycling, sand and dust abrasion, hotspot endurance, and high-temperature mechanical loading to reflect real desert conditions.
### Key Reliability Tests
- UV aging tests to model long-term exposure in high-irradiance regions.
- Thermal cycling to simulate repeated large temperature swings.
- Sand abrasion and dust tests to evaluate front-surface durability and soiling resistance.
- Hotspot and high-temperature mechanical load tests to ensure structural and electrical stability under stress.
## DesertBlue Module Focus
At the core of the white paper is JA Solar’s DesertBlue module series, specifically engineered for desert and semi-arid deployment. The product is presented as a flagship solution that integrates multiple design enhancements aimed at boosting output while maintaining reliability in dusty, high-temperature environments.
### Performance and Efficiency
- DesertBlue modules reach power output up to 650 W with efficiency up to about 24%, targeting utility-scale plants.
- The optimized thermal design improves performance at high operating temperatures, enabling up to 0.6% higher power output compared with conventional modules under similar hot conditions.
## Anti-Dust Surface Technology
A notable feature is a nano-scale anti-dust coating applied to the module surface. This coating helps reduce the rate at which transmittance declines due to dust accumulation by more than 32%, contributing to an additional three to five years of effective service life under desert soiling conditions.
### Cleaning and O&M Benefits
- Reduced dust adhesion lessens the frequency of manual or robotic cleaning, which can be costly and logistically challenging in remote desert sites.
- Lower cleaning requirements support reduced operation and maintenance (O&M) expenses over the project lifetime.
## Mechanical Strength and Structure
DesertBlue incorporates a reinforced steel frame designed to handle extreme mechanical loads typical of sandstorm-prone areas. The frame is rated for around 6000 Pa on the front and 4000 Pa on the rear, improving resistance to high winds and heavy loads such as drifting sand.
### Thermal and Operating Characteristics
Field measurements presented in the white paper indicate that DesertBlue modules can operate almost 5°C cooler than conventional modules in dusty, high-irradiance environments. Lower operating temperatures help maintain higher power output and slow long-term degradation of key components.
## Field Results and Empirical Data
Outdoor empirical tests are highlighted as evidence of DesertBlue’s performance advantages. The white paper cites data from different sites and conditions to illustrate the gains in energy yield and cost-effectiveness achieved by the new solution.
### Reported Energy Yield Gains
- At JA Solar’s Shanghai Fengxian Base, DesertBlue achieved an energy yield increase of about 7.09% compared with reference modules under high-dust simulations.
- In China’s Ulan Buh Desert, field tests showed an approximately 4.98% higher energy yield versus conventional modules.
These improvements, although dependent on local conditions and system design, are positioned as indicative of the module’s advantage in dusty and hot environments.
## Lifecycle Costs and LCOE
The white paper links higher energy yield with reduced cleaning and O&M needs to demonstrate lower lifecycle costs for projects that adopt the DesertBlue solution. By increasing production and lowering maintenance, the solution is intended to reduce the levelized cost of electricity (LCOE) for large-scale installations in desert, Gobi, and wasteland regions.
## TÜV NORD Validation
The reliability framework and test results described in the paper have been independently validated by TÜV NORD. This external assessment is used to support claims that DesertBlue can maintain performance under stress levels exceeding typical IEC standard requirements for PV modules.
## Scenario-Based Innovation
JA Solar frames the Desert-Gobi-Wasteland PV Solution White Paper as an example of scenario-based innovation focused on specific environmental challenges. Instead of designing modules primarily for generic conditions, the company emphasizes tailormade solutions for high-irradiance, high-dust, and high-temperature regions.
## Company Statement
> “The release of this white paper reflects JA Solar’s commitment to scenario-based innovation and high-performance PV solutions. 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.”
This quote from Aiqing Yang, Executive President of JA Solar, underscores the strategic focus on durability and economic performance in demanding environments.
