The intent of this standard is to provide minimum infor
15、mation required to configure safe and optimal photovoltaic modules. In this context, data sheet information is a technical description separate from the photovoltaic module. Product data information concerns the packaging, marking, storage and containing a commitment to inform about major changes on
16、 product and on process. These data are needed for further processing of solar cells to photovoltaic modules. 2 Normative references The following referenced documents are indispensable for the application of this document.
