Abstract
To sustain the green transition, the Photovoltaic (PV) source is called to play a relevant role. To this aim the optimal energy yield of PV plants must be ensured by smart monitoring and diagnostics tools based on module-level characterization devices declined as IoT (Internet of Things) sensors. In this paper, the authors discuss the applicability of a I-V (current-voltage) tracer conceived to perform online electrical characterization of individual PV modules, to be adopted also for impedance spectroscopy analysis. Numerical simulation performed in Spice environment proves the applicability of the proposed approach. Nevertheless, challenging design aspects are also highlighted.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
