IEC 62670-2:2015 specifies the minimum requirements for determining the energy output and performance ratio for CPV modules, arrays, assemblies and power plants using an on-sun, measurement based method. This International Standard is intended to define testing methods, to establish a standard energy measurement for CPV modules, arrays, assemblies and power plants, and to specify the minimum reporting information.
