Aerial Thermography Testing with UAVs

Aerial Thermal Mapping with Drones: Smart Monitoring, Precise Diagnostics

Aseman-Rasad Hadi, officially licensed for drone operations by the Civil Aviation Organization, is among the few authorized companies in this field. We provide specialized thermal monitoring services for solar power plants using drones. According to national regulations, all drone operations—including imaging, mapping, or industrial monitoring—must be performed exclusively by companies holding official licenses. This license guarantees compliance with safety, technical, and legal requirements.

 

Aerial Thermography Services: Two Complementary Approaches

We offer aerial thermography services in two main categories, each tailored to the specific needs of solar plant operators:

1. Thermal Inspection with Drones

Using pre-designed flight plans, drones autonomously fly over the solar plant and capture high-resolution thermal images of panel surfaces. These images reveal temperature patterns and enable rapid identification of defects such as:

  • Open or short-circuited strings
  • Open or short-circuited PV panels
  • Hot spots on PV panels
  • Bypass diode problems

This method is highly effective for fast, initial monitoring and significantly reduces inspection time and costs in large-scale projects.

2. Geo-Referenced Thermal Mapping

Another approach is thermal mapping, where a geo-referenced map of the plant’s thermal condition is generated. This provides a comprehensive and unified view of the entire plant, enabling project managers and operators to:

  • Pinpoint the exact location of defective panels
  • Classify defects by severity and type
  • Gain an overall snapshot of plant condition

These maps serve as reliable technical documentation for maintenance, warranty claims, and performance optimization. Detailed reports for each defective panel are also provided, similar to the first method

Example of extracting defects in a solar power plant through thermography:

Intelligent Analysis with Artificial Intelligence: Our Exclusive Technology

What sets our services apart is the use of proprietary AI algorithms for automated thermal image analysis. Over the years, our R&D team has focused on machine learning and image processing to develop a smart system capable of:

  • Automatically detecting and classifying defects
  • Determining defect severity and type
  • Providing actionable outputs for technical decision-making

This exclusive technology has already been successfully deployed in large-scale multi-megawatt projects.

Complementary Tests After Defect Detection

After identifying suspicious or defective panels during thermography, our technical team conducts on-site inspections and applies complementary tests for more precise diagnostics:

  • Electroluminescence (EL) Testing: Reveals micro-cracks, cell fractures, and structural defects invisible in thermal images.
  • IV-Curve Testing: Assesses electrical performance and quantifies power loss or deviations from expected characteristics.

This combination of aerial monitoring, intelligent analysis, and field testing provides a comprehensive solution for preventive maintenance and enhanced plant efficiency.
