摘 要：As the photovoltaic (PV) industry continues to develop, the vast size of deployments today requires optimization of product reliability. The safe operation, requisite service life, reliability, and durability of PV modules become increasingly important as incentives are reduced and the value of an investment in PV is reflected in the kilowatt hours (kWh) generated over the lifetime of the product. Solar electricity can be cost competitive in many electricity markets today (1) if solar panels can perform to warranted specifications for at least the length of their warranty, which is typically 25 years. But, it can be difficult to identify which PV modules will meet their warrantied performance level. Design qualification testing using tests such as IEC 61215 (2) and IEC 61730 (3,4) has been key for achieving high reliability. The continued maintenance of these standards and the development of new standards that address wear-out mechanisms will continue to improve the durability and reliability of products going into the field.
