Abstract: This project demonstrated an application of photovoltaic (PV) technology to power cathodic protection (CP) systems for water tanks at Pohakuloa Training Area (PTA), HI. An impressed-current CP system was installed on each of three water tanks in isolated locations, where connecting with the local power grid would be expensive. The demonstrated system, powered only by PV arrays with a battery backup, uses ceramic anodes and includes a satellite-based remote-monitoring capability. This system provides uniform and reliable cathodic protection in the water tanks interior below the water line. Data collected by the remote monitoring system can be loaded into a spreadsheet, and performance can then be analyzed on a pass-fail basis. The installed PV-powered CP systems operate as designed and conform to NACE SP 0169 criteria. It is expected that little maintenance will be needed to keep the system operating properly. Required maintenance will include periodic cleaning solar arrays and monthly recording of electrical output using a digital meter. Once every year, a qualified CP specialist should survey the system to ensure proper CP levels.
