  • Due diligence on required cyclone rating of non-penetrative rooftop array fixings
  • Construction delays due to COVID and wet season
Project Results:
  • NTPWC negotiation led to inverter ramping being achieved solely via cloud camera equipment, minimising power curtailment and removing the need to install an additional costly battery (BESS) 
  • Supervision and guidance (in the face of COVID and wet season delays) resulted in the successful completion of the solar system to regulatory standards and site owner specification and quality requirements.
