Supervisory Control And Data Acquisition (SCADA) systems are frequently located in remote, environmentally hostile locations. Even in favorable conditions, the Remote Terminal Unit's (RTU) location often dictated function with a minimum of maintenance and routine oversight from operators. These criteria imply that these systems must be durable, reliable, and portable. Without an equally durable, reliable, and portable power source, these systems cannot carry out their intended functions. Photovoltaic (PV), or solar power, systems can meet these conditions. This paper will present an overview of the steps involved in designing and installing PV power systems supplying RTUs. Reviews of two Arco systems are included.
