Progress Update: Task Group 6
Task Group 6 is focused on how to communicate the conclusions of the Task Force.
This group is discussing how to best communicate with PV customers, including financial investors, insurance companies, PV owners, etc. The group facilitates discussion between this broad spectrum of people and the engineers who are designing the tests. As the other task groups recommend test methods and the associated test results, this group will review these to confirm that the presentation of the results is in a format that is easily understood by others wishing to access this information.
The group's discussions have consistently concluded that a rating system should be communicated through climate-specific labels rather than by stress-specific labels. A structure of the rating system has been proposed to the IEC standards group (Technical Committee 82, Working Group 2). A paper was presented at the 39th Photovoltaic Specialists Conference. Feedback has indicated that it would be better to simplify this further, so a proposal of three climate zones (e.g., temperate, desert, and tropical) and two mounting configurations (open-rack and close-roof) may provide the basis for a comparative rating system.
A Framework for a Comparative Accelerated Testing Standard for PV Modules — As the photovoltaic industry has grown, the interest in comparative accelerated testing has also grown. Private test labs offer testing services that apply greater stress than the standard qualification tests as tools for differentiating products and for gaining increased confidence in long-term PV investments. While the value of a single international standard for comparative accelerated testing is widely acknowledged, the development of a consensus is difficult. This paper strives to identify a technical basis for a comparative standard.
