97% efficiency gain across four utility-scale solar farms

A multi-site comparative study validated drone-based 100% infrared inspection against conventional manual methods — clamp testing, handheld IR, and IV curve tracing — across 137.5 MW of capacity.

The challenge

EagleNXT evaluated whether drone-based 100% IR inspection could replace conventional manual methods across four solar sites ranging from 12.5 MW to 74 MW. Each site used a different legacy inspection method — clamp testing with 20% IV curve tracing, Voc/Isc testing at combiner box level, 100% handheld IR scanning, and full IV curve tracing — making this a uniquely comprehensive comparison.

The sites

Sumrall, Mississippi74 MW
Clamp testing + 20% IV curve
Sprague, Connecticut30 MW
Voc/Isc at combiner + visual
Rincon, Georgia21 MW
100% handheld IR + 15% IV curve
Herald, California12.5 MW
100% IV curve tracing

The solution

Each site received a 100% infrared drone inspection. RGB and thermal datasets were combined with automated defect detection, geo-located anomaly mapping, and manual QC classification. Final reports were delivered within 5 business days of data collection.

The results

Across all four sites, drone inspection was 97% more efficient than manual methods. The drone inspection rate was 10 minutes per MW — compared to days per site with ground crews. Cost savings ranged from $1,074 to $1,717 per MW, averaging $1,254/MW.

Crucially, when manual inspection crews revisited to validate drone findings, they confirmed results with 99% accuracy — but the manual validation alone took 2 days per site versus 2 hours with the drone.
