Stc stands for standard test conditions and are the industry standard for the conditions under which a solar panel are tested.
Standard test condiitions solar panels.
Solar panel output is expressed in units of watts w and represents the panel s theoretical power production under ideal sunlight and temperature conditions.
The electric output performance of crystalline silicon and thin film pv modules are generally measured under standard test conditions stc ensuring a relatively independent comparison and output evaluation of different solar pv modules.
By using a fixed set of conditions all solar panels can be more accurately compared and rated against each other.
They enable the evaluation and comparison of different solar panel types by determining current voltage and power of solar pv panels under comparable test conditions.
This includes determining a panel module s temperature coefficient open circuit voltage and maximum power output.
Temperature of the cell 25 c.
Standard test conditions stc a solar panel is first tested right in the factory.
The panel is then flashed with fake sunlight.
Manufacturers use stc testing to ensure that photovoltaic panels with similar energy output can be sold and used together.

There are three standard test conditions which are.
By using a fixed set of conditions all solar panels can be more accurately compared and rated against each other.
Standard test conditions stc tests another central solar panel test procedure is the standard test conditions tests stc tests which are run for all solar pv panels.
All solar panels are rated by the amount of dc direct current power they produce under standard test conditions.
