Our Expertise
Solar PV Thermographic Inspections
Locate thermal anomalies and visible concerns in PV modules, with clear findings to support targeted checks and maintenance.
Understand the condition of your PV installation through aerial thermal and visual inspections. We identify abnormal temperature patterns, locate affected modules and provide evidence to support further investigation and maintenance planning. Inspections can cover individual installations, commercial rooftops and solar parks, with reporting tailored to your requirements.
Drone inspections can reduce the need to walk on roofs or access elevated PV installations, limiting personnel exposure to work-at-height hazards.
What Can Be Detected?
Clear findings for better decisions.
- Localised hotspots and abnormal cell temperature patterns
- Thermal patterns consistent with bypass-diode activation or substring issues
- Temperature differences between modules or groups of modules
- Visible soiling, shading and physical damage
- Areas requiring follow-up electrical testing
Methodology
Planned around safety and data quality.
We review the site information and agree the inspection scope before planning thermal and visual image capture. Our PV thermographic methodology draws on the principles of IEC TS 62446-3. Findings are assessed alongside available visual evidence, operating information and recorded inspection conditions. Qualitative screening or quantitative temperature assessment can be agreed according to the project requirements and available measurements. Inspection conditions, limitations and recommended verification checks are documented in the report. Planning includes a site-specific risk assessment, coordination with the responsible site personnel and definition of suitable operating areas and safety distances.
