Field Reliability Evaluations

PV systems are unique in design, installation and location.  As such, each system will likely have unique aging and performance degradation characteristics. For example, a system installed near a body of salt-water may age differently relative to a system installed in an inland location. ASU-PRL has been performing field reliability evaluations across the United States and as of date has evaluated over 50 Utility owned/operated PV powerplants in various climatological regions of the United States (AZ-Hot-dry; CA,CO-Temperate; NY-Cold-dry; FL,TX-Hot-humid). The environmental stresses vary by the climatological region and some failure mechanisms are more predominant than the others.

ASU-PRL is equipped to perform field safety and performance inspection like visual inspection, diode failure check, IR scanning, IV measurements for strings and modules, and inverter power quality analysis.
