This part of IEC 62670 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.<\/p>\n

The purpose of this International Standard is 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.<\/p>\n
