What is BS EN 61853-1 - Irradiance and temperature performance measurements of PV module about?
BS EN 61853 is an International Standard series that discusses photovoltaic (PV) modules. It establishes IEC requirements for evaluating PV module performance based on power (watts), energy (watt-hours) and performance ratio (PR). It is written to be applicable to all PV technologies including non-linear devices, but the methodology does not take into account transient behaviour such as light induced changes and/or thermal annealing. BS EN 61853-1 is the first part of the BS EN 61853 series that describes requirements for evaluating PV module performance in terms of power (watts) rating over a range of irradiances and temperatures The object of BS EN 61853-1 is to define a testing and rating system, which provides the PV module power (watts) at maximum power operation for a set of defined conditions. A second purpose is to provide a full set of characterization parameters for the module under various values of irradiance and temperature. This set of measurements is required in order to perform the module energy rating described in IEC 61853-3 .
