Solar Array & PV Thermal Audits
High-speed aerial radiometric thermographic scanning of rooftop and ground-mounted solar arrays. Detect defective cells, bypass diode failures, micro-cracks, and electrical overheating without interrupting power generation.
Maximizing Solar Efficiency & Preventing Electrical Fires
Faulty photovoltaic (PV) modules, failed string bypass diodes, and cracked solar cells dissipate electrical energy as localized heat rather than generating clean power. Over time, these thermal hotspots cause permanent efficiency degradation and create severe fire hazards. Flow Services utilizes sUAS thermal imaging to audit thousands of solar panels in minutes during peak solar generation cycles.
Thermal Anomalies Identified
- Hotspot Cell Detection: Locate individual defective silicon cells operating at elevated thermal temperatures due to micro-cracks or delamination.
- Bypass Diode Failures: Isolate entire sub-strings of panels bypassed and overheating due to failed diode junction boxes.
- String & Inverter Inefficiencies: Detect open-circuit strings, reversed polarity wiring, and combiner box connection resistance.
- Zero Shutdown Operational Inspection: Audits are conducted while the system is fully operational and generating power.
