PT Tetra Daya Mandiri (TDM) continues to prove its technical agility and execution capability in complex Operations & Maintenance (O&M) environments. In July 2026, TDM successfully executed a selective PV dismantling and reinstallation project for the 4.78 MWp rooftop solar PV facility at PT Indokordsa Tbk in Bogor, West Java.


The specialized scope was carried out to accommodate crucial roof repair and structural maintenance activities required at the manufacturing plant while keeping system downtime to an absolute minimum.

Project Highlights & Key Metrics

  • Site Location: PT Indokordsa Tbk – Bogor Manufacturing Facility, West Java

  • Total Installed System Capacity: 4.78 MWp (Rooftop PV System)

  • Execution Period: July 2026

  • Asset Owner: TotalEnergies ENEOS / TotalEnergies

  • O&M Special Scope: Partial PV Array Dismantling & Reinstallation (Roof Repair Support)

  • Executing Contractor: PT Tetra Daya Mandiri (TDM)

Scope of Work & Technical Execution

Executing panel removal and re-integration on an operational C&I rooftop demands strict adherence to safety and handling procedures. TDM’s technical team managed the end-to-end scope across multiple operational phases:

  1. Selective Decommissioning & Safe Storage: Systematic isolation of DC strings, controlled unmounting of modules and racking structures, and secure staging of PV equipment on-site to prevent mechanical or structural damage during roof repair operations.

  2. Reinstallation & Structural Re-alignment: Precise re-mounting and re-anchoring of the PV array post-roof repair, maintaining exact tilt angles and structural torque specifications.

  3. Electrical Re-connection & String Health Audit: Complete DC cabling re-integration, insulation resistance testing, string open-circuit voltage ($V_{oc}$) verification, and thorough continuity checks before energization.

  4. HSE & Fall Protection Compliance: Strict implementation of working-at-height safety protocols in alignment with international standards, ensuring zero harm during high-risk rooftop logistics.
