The stc rating of a solar module is determined by carefully controlling light and temperature in the testing environment.
Solar pv stc calculator.
Photovoltaic system performance predictions calculated by pvwatts include many inherent assumptions and uncertainties and do not reflect variations between pv technologies nor site specific characteristics except as represented by pvwatts inputs.

Calculate the number of stcs for solar energy pv and solar hot water shw systems.
The solar panel yield of a pv module of 250 wp with an area of 1 6 m2 is 15 6.
System capacity kw.
The light source in the laboratory is calibrated so that precisely 1 000 watts per square meter of solar light falls on the photovoltaic panel.
Stc is an industry wide standard to indicate the performance of pv modules and specifies a cell temperature.
Certificates based on your selections.
For example pv modules with better performance are not differentiated within pvwatts from lesser performing modules.
The deeming period was set by the scheme and decreases every year until 2030.
Be aware that this nominal ratio is given for standard test conditions stc.
It allows homeowners small building owners installers and manufacturers to easily develop estimates of the performance of potential pv installations.
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.
