Papua New Guinea Photovoltaic Cable Tray

The Papua New Guinea Photovoltaic Cable Tray Project is part of broader renewable energy initiatives deploying solar PV systems and supporting infrastructure to expand electricity access in rural and off-grid communities.

Project Overview

The project focuses on installing solar photovoltaic (PV) systems in schools, health facilities, and rural communities across Papua New Guinea, particularly in East and West Sepik Provinces . These systems include solar panels, inverters, battery storage, and cable trays to safely route electrical wiring and ensure reliable power distribution. Cable trays are critical for organizing and protecting PV system wiring, especially in institutional and industrial installations.

Implementing Agencies and Support

The project is implemented under the EU-funded STREIT Programme, with UNDP leading installations and training local technicians . Companies like FTMRS Solar and Cetelnet provide technical support, system design, and maintenance services, ensuring PV systems operate efficiently over their lifecycle . These agencies also supply PV cables, energy storage solutions, and hybrid systems for off-grid and partially grid-connected sites.

Technical Components

• Solar Panels: Convert sunlight into electricity for local consumption.
• Cable Trays: Organize and protect electrical wiring from environmental damage and facilitate maintenance.
• Battery Storage: Ensures continuous power supply during nighttime or cloudy conditions.
• Inverters: Convert DC electricity from solar panels into AC for use in buildings and grid integration.
• Hybrid Systems: Combine solar with existing diesel generators or grid connections to improve reliability .

Community Impact

The project enhances electricity access, which currently reaches only about 20% of PNG's population . Benefits include:

• Education: Schools can operate digital classrooms and lighting systems.
• Healthcare: Clinics gain reliable power for lighting, refrigeration, and medical equipment.
• Agriculture and Small Enterprises: Solar-powered dryers, freezers, and cold storage improve food preservation and value addition .
• Local Capacity Building: Training programs equip electricians, engineers, and teachers with skills to maintain PV systems, fostering local expertise .

Off-Grid and Remote Applications

For communities far from the national grid, off-grid PV systems and microgrids provide essential electricity for lighting, water pumps, communications, and refrigeration . These systems are designed to comply with PNG's regulatory requirements and are often self-consumption oriented, ensuring sustainability and long-term reliability.

Conclusion

The Photovoltaic Cable Tray Project in Papua New Guinea is a strategic initiative to expand renewable energy access, combining technical infrastructure like cable trays with solar PV systems, energy storage, and local capacity building. It supports education, healthcare, agriculture, and community development while promoting sustainable and reliable electricity in rural and off-grid areas .
