Solar cell I-V characteristic curves that summarise the relationship between the current and voltage are generally provided by the panels manufacturer and are given as: = open-circuit voltage – This is the maximum voltage that the array provides when the terminals are not connected to any load (an open circuit condition).
The PV characteristic curve, which is widely known as the I–V curve, is the representation of the electrical behavior describing a solar cell, PV module, PV panel, or an array under different ambient conditions, which are usually provided in a typical manufacturer’s datasheet.
Other important characteristics include how the current varies as a function of the output voltage and as a function of light intensity or irradiance. The current-voltage (I-V) curve for a PV cell shows that the current is essentially constant over a range of output voltages for a specified amount of incident light energy.
The electrical characteristics of a photovoltaic array are summarised in the relationship between the output current and voltage. The amount and intensity of solar insolation (solar irradiance) controls the amount of output current ( ), and the operating temperature of the solar cells affects the output voltage ( ) of the PV array.
