Drone Solar Panel Inspection
Flag visible and surface-temperature investigation targets across accessible array areas; qualified ground testing determines string, module, or diode condition.
Manual IV-curve tracing and visual inspections of utility-scale solar farms are too slow, too expensive, and statistically incomplete. Drone solar panel inspection has become the industry standard for O&M providers because it allows for systematic radiometric coverage of accessible site areas in a fraction of the time. Planned coverage does not guarantee detection; gaps and rejected frames are disclosed.
At Aerial Accuracy, we fly strict, automated grid patterns over PV arrays using high-resolution radiometric thermal sensors. We record per-pixel apparent-temperature data and screen for thermal signatures. Signatures are prioritized for ground verification; software labels are not root-cause diagnoses.
Localized Hotspot Patterns
We flag nonuniform surface-temperature patterns as investigation targets. Qualified visual and electrical ground testing determines root cause, maintenance priority, and any safety action.
Bypass Diode Failures
When a bypass diode fails, an entire sub-string (usually 1/3 of the panel) goes offline. In a thermal image, this appears as a distinct, rectangular thermal anomaly spanning the length of the module.
String Outages
A thermal survey can flag string-shaped nonuniform patterns for qualified electrical follow-up; testing determines whether cabling, fuses, inverter inputs, or another cause is responsible.
PID & Soiling
Checkerboard and other nonuniform patterns may warrant qualified follow-up for PID, soiling, shading, or other causes.
Stop Leaving MWs on the Table
Even a 2% energy loss on a 50 MW facility translates to tens of thousands of dollars in lost annual revenue. A comprehensive drone survey pays for itself by finding the "low hanging fruit" (like disconnected strings) while simultaneously building your warranty claim database against the module manufacturer.
