We perform live electrical testing, error-code analysis, and communication diagnostics to isolate whether the fault is firmware, hardware, or grid-side. Replacements are spec-matched and the updated single-line diagram is provided with every swap.

Electroluminescence imaging and IV curve tracing identify cracked cells, hot spots, and PID before they cascade. Matched-spec modules are sourced and installed with torque-verified racking hardware.

Cross-mated connectors, UV-degraded jacketing, and undersized conduit are the most common arc-fault sources we find. We re-terminate to manufacturer spec and megger-test each string before recommissioning.

Failed flashings, loosened attachments, and corroded rails are documented photographically, then repaired and re-certified. A PE-stamped structural letter is reissued for the as-built condition.

Post-event inspections combine drone thermography, ground survey, and production data review. The resulting report is formatted for carrier adjusters and AHJ resubmittal, with repair scope and cost basis included.

We benchmark actual production against a modeled expectation, then work down from array-level to string-level to isolate losses — soiling, shading, clipping, degradation, or component failure — and quantify the payback of each fix.
