Experience with CPV Module Failures at NREL (Presentation)

PDF Version Also Available for Download.

Description

The failures and performance issues associated with three years of on-sun testing of CPV modules are discussed. Pictures of various failure mechanisms and performance issues are presented. A wide array of CPV module failures and performance issues have been experienced at NREL. Many of the modules are prototypes and have not been through qualification testing. It is assumed that the qualification test would have captured many of the problems. Internal lens soiling due to condensation is not currently captured by the qualification test. Lens temperature dependence can be built into modeling if CPV is to operate in cold locations.
