Procurement, Testing & Long-Lead Items

Procurement, Testing & Long-Lead Items

Your project schedule is only as strong as your supply chain.

Procurement delays can quietly derail even the most well-planned (on paper, or on MS Project) solar and BESS project.

Critical Procurement Considerations

So you might want to consider this:

Long-Lead Items & Supply Chain

Has your procurement plan locked in all long-lead items early on?

  • Transformers
  • Switchgear
  • Inverters
  • BESS containers
  • Recent Market Challenges:

    Since the federal battery grant started from July this year, it is extremely difficult to get hold of residential batteries. Have you factored the impact of such news into your schedule?

    Manufacturing & Logistics

    Have you confirmed:

  • Manufacturing slots and shipping timelines?
  • Factory Acceptance Tests (FAT) booking and witnessing?
  • Delivery schedules aligned with installation windows?
  • Warranties & Performance

    Are warranties in place — and do they match your project's required performance expectations?

  • Equipment performance guarantees
  • Long-term warranty coverage
  • Maintenance and support agreements
  • Testing & Certification

    Are solar panels tested and certified for your region's conditions?

  • Temperature performance ratings
  • Cyclone ratings for NT and tropical regions
  • Salt spray and corrosion resistance
  • CEC Compliance & Standards Updates

    Are you ensuring that the major equipment are listed on the Clean Energy Council?

    On 23rd August, CEC sent a notification that only 1,662 models of inverters are on the approved inverter list as per the updated standard AS 4777.2:2024.

    Do you keep yourself updated of such changes on a regular basis?

  • Standards updates and transitions
  • Equipment re-certification requirements
  • Compliance deadline management
  • Contingency Planning

    Do you have contingency plans for supply chain disruptions?

  • Alternative suppliers identified
  • Buffer times in schedule
  • Risk mitigation strategies
  • A single delayed or non-compliant component can snowball into missed milestones, perhaps liquidated damages, and even lost revenue.
