I-V Characteristics of a PV module

The current and voltage are the two main attributes of a photovoltaic module. The performance of a pv module can be determine by these descriptors. The I-V characteristics represents an infinite number of direct current and voltage operating points and varies with solar radiation and cell temperature.


As we know that power is the product of voltage and current,therefore, maximum power can be extracted at a point where voltage and current is maximum as shown in the above graph.
