Identifying Internal Defects of Photovoltaic Panels Using Sweep Frequency Response Analysis

Solar irradiation is the main energy source which can sustainably provide all of energy needs on the earth. Because of fast progress in direct conversion of solar energy to electricity, photovoltaic (PV) converters are going to become major devices to supply world energy requirements. Similar to other electricity generators, PV panels may be defected in production stage or in the field. Thus, it is necessary to detect these defects as soon as...
