QAQC Verification

We verify all installed components across your solar field—DC, AC, and communication infrastructure. Our team ensures your system meets utility-grade standards before energization, with detailed punchlists and pass/fail documentation.

Commissioning Services

Our commissioning process validates the operational readiness of your solar infrastructure through a series of structured electrical and performance tests. This includes visual mechanical inspections (VMI) to confirm installation quality and adherence to project specifications, open-circuit voltage (VOC) testing to ensure proper string polarity and voltage levels, insulation resistance (IRT) testing on both DC and AC circuits to verify electrical isolation and safety, and grounding continuity testing to confirm proper bonding and grounding throughout the system. All test results are documented in a standardized format to ensure traceability, safety compliance, and readiness for utility energization.

Drone Thermal Imaging & Reporting

Using thermal drones, we identify hot spots, string-level performance issues, and potential diode or shading faults. Our inspection includes annotated reports, photo overlays, and flagged anomalies per row and tracker.
