STC

STC (Standard Test Conditions) is the test condition used to give PV panels their power ratings. When determining the STC rating, the PV panel is hand selected (usually the best cells in the lot), flashed with a controlled light source at 1000 W/m2, with the cell and air temperature at 25°C (68°F) and 0 m/s wind speed.

Basically, when the PV panel is flashed with the light source the power output is measured. So, a panel which has a rating of 165W on the rating label (typically shown as Maximum Power and represented as Pmax), will produce 165W of DC power when subjected to the STC test conditions. These conditions are, in fact, far from real-world.
