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