scope:

Lays down requirements and associated tests for the design qualitification and type approval of the module suitable for long-term operation in general open-air climates, as defined in IEC 721-2-1. Standards for thin-film modules and other environments, such as marine or equator conditions, are under consideration. The object is to determine the electrical and thermal characteristics of the module and to show, as far as is possible within reasonable constraints of cost and time, that the module is capable of withstanding prolonged exposure in climates described in the scope.
