Solar module mechanical measurement and mechanical modeling technique for rapid parametric design

As warranties on solar modules continue to expand, mechanical reliability of modules has become extremely important. Several industry standards exist to simulate conditions that modules will face in their lifetime. Among these standards are the IEC 61215/61646 and UL 1703. These tests specify the application of even pressure across the face of the module, at a given magnitude, for a given duration at room temperature (22°C). Effectively measuring and modeling these test standards will allow design of much more robust systems while maintaining cost efficiency. This paper will describe the development and validation of a standards-based mathematical model that enables rapid initial screening of module designs and components for improved module durability. The paper will be presented in four sections: 1.) the test setup and procedure; 2.) model development; 3.) model validation; and 4.) rapid parametric studies.
