standard operating conditions (SOC)

Standard operating conditions (SOC) is a set of reference photovoltaic device measurement conditions consisting of irradiance of 0.8 kilowatts per square meter (W/m2), 20°C ambient temperature, and average windspeed of 1 meter per second (m/s), with the wind oriented parallel to the plane of the array, and all sides of the array fully exposed to the wind.
