Photovoltaic (PV) module performance testing and energy rating - Irradiance and temperature performance measurements and power rating

BS EN 61853-1:2011 Photovoltaic (PV) module performance testing and energy rating. Irradiance and temperature performance measurements and power rating

BS EN 61853-1 describes requirements for evaluating PV module performance in terms of power (watts) rating over a range of irradiances and temperatures

The object of this part 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. It also provides 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 BS EN 61853-3.

Soon to be published:

BS EN 61853-2 describes test procedures for measuring the performance effect of angle of incidence; the estimation of module temperature from irradiance, ambient temperature and wind speed; and impact of spectral response on energy production.

BS EN 61853-3 describes the calculations of PV module energy (watt-hours) ratings. IEC 61853-4 describes the standard time periods and weather conditions that can be utilized for calculating standardized energy ratings.
