Multi PV Array Analysis & Real Time Monitoring Using Two WIRE Interface

The goal of this paper is to create an online realtime photovoltaic monitoring system. This is achieved by designing a photovoltaic system, building the analog circuitry for proper voltage, current, solar radiation and temperature readings, and creating a analysis datalogging that displays the monitored data in a user-friendly charting interface. The communication interface is in 2 wire protocol and could therefore be accessed numbers of solar panel. The project could potentially be adapted to service different types of photovoltaic systems to insure proper functioning and data monitoring.
