Understanding the Voltage – Current (I-V) Curve of a Solar Cell
The operating point (I, V) corresponds to a point on the power-voltage (P-V) curve, For generating the highest power output at a given irradiance and temperature, the operating point should such correspond to the maximum of the (P-V) curve, which is called the maximum power point (MPP) defined by (Impp* Vmpp).

Standard Test Conditions (STC) of a Photovoltaic Panel
However, a photovoltaic panel does not produce a fixed DC voltage and current output, rather one that varies considerably under different operating conditions. Then buying and installing a PV solar panel rated for a particular STC wattage, for example 100 watts, may not produce such a maximum power output when installed on your roof.
