Solar panel thermal inspections

Solar panel thermal inspections
Utility-scale farms, commercial arrays and residential systems across the Shenandoah Valley and the Mid-Atlantic. A radiometric thermal pass finds the modules that are not earning.
The work
What this actually involves

A solar array fails quietly. A cracked cell, a failed bypass diode, a shaded or soiled module, a bad string connection - none of it announces itself, and none of it shows on a walk-around. What it does do is run hot, and a radiometric thermal camera sees that from the air in a single pass.

Blue Horizon Drone flies solar with a DJI Matrice 4T, collecting radiometric thermal and high-resolution visual imagery simultaneously. Every anomaly comes back with a temperature, a location in the array and a photograph, so an O&M crew knows which module to walk to rather than which field to search.

The work suits commissioning acceptance, annual O&M surveys, warranty claims and pre-purchase due diligence. For a farm of any size it is faster than a handheld survey by an order of magnitude, and it does not require taking the array offline.

What's covered
  • Utility-scale solar farms
  • Commercial solar arrays
  • Residential solar systems
  • Hot spot detection, string and module analysis
  • Commissioning and O&M support
What a survey turns up
What gets found
  • Hot spots and cell-level defects
  • Failed bypass diodes
  • Underperforming or dead modules
  • String and combiner faults
  • Soiling and shading losses
  • Junction box failures
  • Cracked or delaminated panels
Typical clients: Solar developers, EPCs, O&M providers, asset owners and commercial property owners with rooftop arrays.
From an actual job
What the camera saw
Thermal capture of a solar array with two measured spot temperatures annotated, 114.1F and 122.9F
Solar array, Rockbridge Baths VA. Two modules on the same string, eight degrees apart. That difference is the entire finding, and it is invisible from the ground.
How a job runs
What to expect
01
Consultation

We discuss your goals, your concerns and what the inspection actually needs to answer.

02
Mission planning

Weather, airspace, site access and safety are evaluated before anything flies. This is the part most operators skip.

03
Data collection

FAA-compliant flight operations. Thermal and high-resolution visual imagery collected with professional-grade equipment.

04
Analysis

Thermal imagery is reviewed for temperature anomalies and areas that warrant further evaluation.

05
Reporting

A detailed report with annotated imagery, observations and findings you can hand to a maintenance team or an adjuster.
