Aerial Thermography
for Utility-Scale Solar
Plants

See More. Inspect Faster. Act Precisely.

Independent, drone-based thermal inspection of MW-scale solar installations to identify module-level thermal anomalies, string-level abnormalities and other performance-related issues.

Nexurja combines DGCA-certified drone operations, thermal imaging and engineering analysis to help solar asset owners and O&M teams identify potential faults and prioritise corrective action.

Why Aerial Thermography?

Faster Inspection

Rapid inspection of large solar fields

Large-Area Coverage

Thermal imaging across MW-scale installations

Georeferenced Findings

Locate anomalies by position

Targeted Maintenance

Help O&M teams focus on affected areas

From Thermal Images to Actionable
O&M Insights

Conventional manual thermography can be time-consuming when large solar fields need to be inspected. Drone-based thermal imaging enables systematic coverage of large areas and helps identify thermal anomalies that may require further investigation.

Nexurja combines aerial thermal imaging with engineering interpretation to create a location-specific inspection report, enabling O&M teams to identify, prioritise and investigate potential problem areas.

How Our Aerial Thermography Works

Site & Flight Planning

Review plant layout, module configuration, site conditions and applicable flight restrictions.

Aerial Thermal Survey

Capture thermal imagery systematically across the designated solar field under suitable operating and environmental conditions.

Thermal Image Analysis

Review thermal patterns to identify abnormal temperature distributions and potential module/string-level anomalies.

Georeferencing

Link identified anomalies to their corresponding location within the solar plant.

Engineering Assessment

Classify and prioritise findings for further field verification and corrective action.

Inspection Report

Provide an actionable report with thermal images, anomaly locations, observations and recommended next steps.

Thermal Anomalies We Look For

Module Hotspots

Identify abnormal thermal patterns associated with potential cell, interconnect or module-level issues.

String-Level Abnormalities

Identify thermal patterns that may indicate string or electrical abnormalities requiring further investigation.

Bypass Diode / Junction-Box Issues

Identify thermal signatures associated with potential diode, junction-box or connection abnormalities.

Electrical & Balance-of-System Anomalies

Where visible within the survey scope, identify abnormal thermal conditions around relevant electrical equipment and connections.

Best Survey Conditions

Thermal inspection results depend on operating and environmental conditions. For meaningful results, the survey should be planned considering:

  • Solar irradiance
  • Plant operating condition
  • Module loading
  • Wind conditions
  • Ambient temperature
  • Recent rainfall or moisture
  • Site accessibility
  • Applicable drone-flight restrictions

Nexurja evaluates site and environmental conditions before the survey and schedules the inspection accordingly.
