Acronym: NOCT

The equilibrium mean solar cell temperature within a module in a standard reference environment of 800 Wm-2 irradiance, 20 degrees C ambient air temperature, and 1 ms-1 wind speed, electrically open-circuited and open-rack mounted at normal incidence to the sun at solar noon.


Note: The ratio of the module efficiency at NOCT to the module efficiency at the standard cell temperature of 25 degrees C is called NOCT efficiency.
