Independent Testing, Inspection & Certification Expertise for Long‑Term PV Performance

Benefits of Our Operation & Maintenance Services

Checking the operating voltage levels of the solar panel switchgear compartment
  • Transparent Insight Into System Performance

    We analyze performance ratios, energy yield data and operational indicators to provide a clear view of how the system performs compared to expectations and design assumptions.
  • Identification of Degradation and Failure Patterns

    Through infrared thermography, visual inspections and data evaluation, we highlight early signs of degradation, hotspots, wiring issues and component failures.
  • Support for Reliable Maintenance Planning

    Independent assessments help operators prioritize actions, schedule maintenance activities and plan refurbishment or repowering measures based on technical findings.
  • Verification of Safety-Relevant Aspects

    We review grounding, protection systems, wiring conditions and compliance with relevant standards to support safe operation throughout the system’s lifecycle.
  • Data-Driven Root Cause Analysis

    Our experts combine on-site inspections with technical documentation reviews to identify underlying causes of performance losses or system malfunctions.
  • Experience Across Global Operating Environments

    With field knowledge from diverse climatic regions and project scales, we apply insights that help operators respond effectively to environmental, structural and technical challenges.
