Scope Overview

The client required a detailed aerial inspection of a large solar farm to assess system performance and identify any post-storm damage affecting energy output. Innovair was appointed to deliver a structured drone inspection campaign that provided high-resolution thermal and visual data, supporting accurate fault detection and efficient maintenance planning.

The goal was clearer site visibility, faster defect identification, and improved understanding of overall array condition.

The Challenge

Inspecting extensive solar arrays presents several challenges for consistent data capture and performance analysis, including:

• Large site area requiring systematic coverage and repeatable flight paths.

• Variations in light and temperature affecting thermal readings.

• Difficulty identifying small defects such as cracked modules or string failures from ground level.

• Need for rapid data turnaround to support time-sensitive maintenance works.

The Solution

Using the DJI Matrice 300 RTK equipped with the H20T thermal payload, Innovair completed automated grid-based flights to capture consistent, high-clarity datasets across the full site.

• Combined thermal and RGB imaging to locate underperforming modules.

• Automated flight routes for even coverage and precise overlap.

• Real-time monitoring for immediate quality assurance.

• Processed datasets into full-site orthomosaics and detailed fault maps.

The Results

• Comprehensive visual and thermal record of the entire array.

• Rapid detection of faults including hotspots, string losses, and damaged modules.

• Actionable data supporting targeted repair planning and reduced downtime.

• All operations completed safely and efficiently with no site disruption.
