Drone Thermography: A Powerful Tool for Enabling PV Module Warranty Claims

Introduction

In the solar energy industry, safeguarding investments through module warranty claims is essential for maintaining performance and stakeholder trust. Drone thermography emerges as an innovative solution, offering a robust approach to facilitating successful claims. This blog explores how leveraging drone thermography can streamline the warranty claim process, providing a comprehensive guide for industry professionals.

Understanding Drone Thermography

Drone thermography involves using drones equipped with thermal cameras to inspect PV modules. This method surpasses traditional inspection techniques by offering unparalleled speed, accuracy, and safety. Unlike manual inspections, drones can cover large areas swiftly, capturing high-resolution thermal images that reveal hidden defects and inefficiencies.
 

Leveraging Drone Thermography for Warranty Claims

a. Planning the Inspection: Selecting the right equipment and drones is crucial for effective inspections. Opt for drones with high-resolution thermal cameras and reliable flight capabilities to ensure precise data collection.

b. Conducting the Inspection: Adhering to best practices is vital for capturing accurate thermal images. Ensure optimal weather conditions and flight paths to identify common defects such as hotspots and shading, which are critical for warranty claims.

c. Analyzing and Reporting: Using advanced IEC-compliant analysis, clients are provided with solid, irrefutable proof of any problems as part of our detailed inspection reports. Equipped with this data, clients can confidently approach their solar installers.

Warranty Claim Success: How Early Inspection Secured a Free Replacement

At Spectrave, we believe in empowering our clients with accurate, actionable insights to protect their solar investments. During a recent drone-based inspection at a client’s solar site, we detected an active bypass diode in one of the panels. This issue can cause:

• Reduced panel efficiency.

• Increased stress on adjacent panels.

• Long-term performance degradation.​

Using our advanced IEC-compliant analysis, we provided the client with solid, irrefutable proof of the problem as part of our detailed inspection report. Equipped with this data, the client approached their solar installer confidently. Hence, the faulty panel was replaced free of cost by the installer under warranty.
 

Advantages of Using Drone Thermography

• Drone thermography enhances accuracy and reliability, significantly reducing the margin of error compared to traditional methods. It is cost-effective and time-efficient, minimizing inspection times and operational disruptions. Additionally, it improves safety by eliminating the need for manual inspections in potentially hazardous environments.

​

Why This Matters:

• Early Detection: Issues like active bypass diodes can go unnoticed without advanced inspection techniques.

• Cost Savings: Identifying the problem early avoided potential long-term losses and ensured a free replacement under warranty.

• Vendor Accountability: Precise data makes it easier to hold vendors/installers accountable.

 

Conclusion

Drone thermography is revolutionizing the way PV module warranty claims are handled, offering unmatched benefits in accuracy, efficiency, and safety. By adopting drone-based inspections, companies can streamline their warranty processes, ensuring swift and successful claims. Embrace this cutting-edge technology to enhance your solar operations and secure your investments. Consider integrating drone thermography into your inspection protocols today for a more reliable and efficient approach to warranty claims.
