PV damage report: when is it necessary?

PV damage can be expensive—but it often gets even more expensive when evidence preservation is poor. A damage report provides a robust basis for the next steps.

Typical situations

• Insurance: Fire, storm, hail, overvoltage, animal bites, vandalism
• Warranty: Installation errors, leaks, wrong design
• Disputes: Operator vs installer / service provider / supplier
• Investors: Assessment of technical risks before purchase/sale

What a good damage report contains

• Evidence preservation (photos, documentation, as-is condition)
• Document cross-check: design, string plan, test reports
• Technical assessment of the damage pattern
• Differentiation of plausible causes (what supports what/what contradicts?)
• Action plan (safety → restoration → prevention)

What you should collect beforehand

• Photos/videos right after the event
• Fault messages/inverter logs
• System documents (plan, string plan, component list)
• Commissioning/test reports
• Event info (date, weather, grid events, fire department report if available)

Why time is a factor

Many findings change: repairs, dismantling, weather, cleaning. The later, the harder a robust assessment becomes. That’s why early evidence preservation is often decisive.

Photos, logs, system documents (plan/string plan), component list, test reports and event info.
