Thresher Test

The Thresher Test is a summation of a series of tests designed to put PV modules through their paces to identify PV modules with truly differentiated long-term reliability and performance of the Bill of Materials (BOM) used. It vigorously simulates environmental stresses on PV modules in order to provide quantitative data behind various degradation modes. Power drop, leakage current and visual observations are also critical items included in the final result.

BUDT (Back Sheet UV Durability Test)  is conducted to identify the quality of the back sheet used. UV is the main stress element designed to focus on the robustness of the ever-changing back sheets being used on PV modules.

MDT (Module Durability Test) is designed to provide a regimented extended reliability test program to characterize BOM changes and robustness of PV modules during its 25+ year lifetime. The test sequences are specifically designed to characterize the Bill of Materials (BOM) in PV modules to highlight strengths and weaknesses in the construction.

Connector Test is designed for PV Module Connectors that will undergo a variety of stresses in the field, sometimes severe, including tension and torsion stresses, thermal expansion & contraction, rubber seal pressure on the connector house, and more. Consequently, standard PV module reliability and durability testing must be complemented with proper testing specifically tailored to assess the durability of connectors.
