What STS Does
Field inspection testing provide independent insight into solar asset performance throughout the project lifecycle. Using advanced diagnostic techniques, STS offers a wide range of services during pre-installation, commissioning, and operation to help identify hidden defects, verify asset condition, and validate system performance to support informed technical and commercial decisions.
EL Imaging & Analysis (Darkroom & Daylight)
Provides flexible defect detection and module condition assessment, from baseline quality verification to in-field identification of hidden cell-level defects.
Handheld IR Thermography
Identifies abnormal heat signatures that may indicate loose connections, failing components, hot spots, or other reliability concerns.
IV Curve Tracing
Measures actual electrical performance under operating conditions to identify underperforming strings, degradation, and production losses.
Drone Infrared Thermography
Uses aerial thermal imaging to quickly detect hotspots, inactive strings, bypass diode failures, and other performance anomalies across PV plants.
BESS SAT Witness
Provides independent third-party oversight during site commissioning to certify that all testing and processes independently verifies system functionality, performance, and safety during site acceptance testing to ensure the BESS is ready for commercial operation.
Weather Damage & Recovery
Uses rapid post-event assessment of PV assets to quantify storm-related damage and support insurance claims, recovery planning, and remediation decisions.
