Title Photovoltaic module V-I and P-V characterization through instrumentation control toolkit of MATLAB
Author Genci Sharko, Nako Hobdari, Nike Shanku, Miranda Ekmekciu, Elton Dasho
Abstract This paper describes one experimental method for determining the V-I and P-V characteristic of the photovoltaic modules. The short-circuit current (Isc), open-circuit voltage (Voc) and the filling coefficient are measured, also. Direct characteristics of V-I and P-V curves under solar irradiance are measured and graphed in real time with system proposed for this reason. It describes the development of an automated monitoring system for a solar PV plant based on the use of Instrumentation Control Toolkit of MatLab Software. PV modules still have relatively low conversion efficiency; therefore, determining and controlling maximum power point tracking (MPPT) for the solar array is essential in a PV system.
