Estimating Crack Effects on Electrical Characteristics of PV Modules Based on Monitoring Data and I-V Curves

This study presents an approach to investigate microcrack effects on the output characteristics of photovoltaic (PV) modules based on a theoretical model that is derived from the equivalent single-diode model through monitoring data and current-voltage (I-V) curves. Meanwhile, an innovative paramete...
