Conventional maximum power point tracking (MPPT) methods exist in various ways and are being actively studied, but there are problems to be improved. This paper proposes an I-V curve tracer based intermittent MPPT control system that can extract the characteristics of PV module & array. Therefore, through the proposed system using the I-V Curve Tracer (IVCT) in this paper, we suggest the possibility of ultimately lowering the LCOE (Levelized Cost of Energy) by increasing the efficiency and lowering the cost from a systemic point of view. Simulation and experimental results of the proposed system show an accuracy of at least about 98 %.
