Photovoltaic devices - Part 5: Determination of the equivalent cell temperature (ECT) of photovoltaic (PV) devices by the open-circuit voltage method

This part of IEC 60904 describes the preferred method for determining the equivalent cell
temperature (ECT) of PV devices (cells, modules and arrays of one type of module), for the
purposes of comparing their thermal characteristics, determining NOCT (nominal operating cell
temperature) or alternatively NMOT (nominal module operating temperature), and translating
measured I-V characteristics to other temperatures.
