Why us?

Objective. Traceable. Robust.

Expert reports for photovoltaic systems must be technically correct—and understandable for third parties. That’s exactly what we specialize in.

Engineering expertise (Dipl.-Ing., TU Berlin)

Practical assessment instead of guesswork.

  • Technical analysis based on the state of the art
  • Documented measurements and plausibility checks
  • Clear conclusions with reasoning

Independent and objective

No ties to manufacturers, installers, or insurers.

  • Neutral view of cause and effect
  • Transparent methodology
  • Focus: facts over interests

Court-ready and robust

Structure, traceability, documentation.

  • Suitable for insurers and disputes
  • Proper evidence preservation and documentation
  • Risk reduction through clear findings

When an expert report really makes sense

In practice, costly wrong decisions often happen because symptoms (e.g., underperformance) are treated without properly proving the cause. An expert report is especially useful for:

Underperformance
Deviation from forecast/expected value
Damage
Fire, storm, hail, installation errors
Investments
Acquisition due diligence / risk assessment

How I work

Short, clear, traceable—no theatrics.

  1. Analysis: Data, documentation, monitoring, damage pattern
  2. Measurement: On-site inspection, electrical measurements, verification
  3. Assessment: Causes, impact, actions, clear recommendation
Result: A robust basis for decisions—for operators, insurers, lawyers or investors.

Free initial assessment

A short description is enough—I’ll give you an honest, technical assessment.
