Photovoltaic and other Remote-Site Power Generation Systems for the Papua New Guinea Telecommunications Network

Over the past six years the Papua New Guinea Telecommunications network has expanded considerably necessitating the requirements for high reliability power supplies for mountain top repeater sites and small capacity telephone exchange terminals in remote locations. Photovoltaic (solar) power systems are considered the most suited for these applications. Furthermore, new microwave systems and large trunk VHF systems are now being installed with photovoltaic power systems ranging in capacity from 300 Wp (watts peak) to 2, 5 KWp for repeater stations and up to 3 KWp for terminal stations. This paper discusses these photovoltaic power supplies in detail with respect to their design, technical composition, configuration with reference to performance and installation requirements.
