Module Temperature

Measuring or predicting module temperature is the first step in estimating cell temperature, which is needed predict the module IV curve.  Module temperature depends on a number of factors, including air temperature, irradiance, wind speed, and module materials.  Most models are steady-state and therefore appropriate for time steps of about 30 minutes or more.  Sandia and ASU just published a new transient module temperature model that is based on a moving average of a steady-state model:
