Why the handover needs certified evidence

When a photovoltaic system with storage is handed over, the state of the work and the documents delivered must stay provable over time. Without objective evidence, a future dispute becomes one party’s word against the other’s.

Disputes after handover

Months later, claims about cracked modules or missing safety measures are hard to disprove without dated proof.

Document delivery gaps

Customers contest never receiving the conformity declaration, diagrams or manuals. You need proof of what was actually delivered.

Lithium storage fire safety

Battery storage adds fire-safety duties: location, compartmentation, ventilation, signage. Their state at handover must be on record.

Evidence that cannot be contested

Inspection evidence must be captured without alteration, carry trustworthy time and origin, and keep a chain of custody. TrueScreen delivers this at the source: an official seal and timestamp with legal value, with time and GPS on every photo and video. Unlike ordinary phone photos, it cannot be edited or contested. TrueScreen certifies the evidence of the inspection, not the technical compliance of the system.

How certification works

Every photo, video and document is captured, verified, sealed and preserved with forensic methodology, so the handover record holds over time.

01

Forensic acquisition

Capture preserves authenticity at the source, with no alteration by AI, people or software.

02

Verification

The acquired information is verified before it is sealed.

03

Certification

An official digital seal and timestamp are applied, internationally recognized and legally incontestable.

04

Preservation

Certified evidence is kept on secure systems, ready for the file.

What the installer captures

On site, the installer captures the installation and the storage safety measures, then imports the documents delivered. Each step is certified the moment it is taken.

Delivered documents

Import the conformity declaration, diagrams, certificates and manuals delivered.

Context and sign off After the visual evidence, the installer adds the site address with GPS, the customer and system data, and the inspection outcome. Installer and customer then sign to confirm the inspection and the handover. Instrumental tests stay in the attached technical report.

What you get

A certified handover record that protects both sides: objective evidence of the installation and proof that the documentation was delivered.

  • Immutable at the source. Every photo and video is sealed on capture, with no later alteration possible.
  • Time and GPS certified. Each piece of evidence carries a certified timestamp and the location of the inspection.
  • Documents proven delivered. Imported files certify exactly what was handed over to the customer.
  • Storage fire safety on record. Photos document location, compartmentation, ventilation and signage of the battery system.
  • Double signature. Installer and customer sign, making the record opposable by both parties.

Platforms and integration

The TrueFlow is available on the TrueScreen App for field work, with the same flow on the Web Portal and integration through API and SDK.

  • App. The TrueFlow runs on the TrueScreen App for iOS and Android, ready for the field.
  • Web Portal. The same flow from the browser, with no App to install, for back-office operators.
  • API and SDK. Integrate the flow into the installer’s own management systems.
