  • 05 2011 09

    Sebastopol CASolmetric has announced this free poster to help solar professionals and trainers develop their understanding of I-V curves. In addition to background information, the poster provides helpful tips on troubleshooting and measurement techniques.Measuring and interpreting I-V curves is getting increased emphasis in the solar PV industry, as they enable array performance verification and troubleshooting. Measurements of DC current vs. DC voltage in a PV system offer important insight into the health of the system. The resulting I-V curve describes how the system is behaving under certain irradiance and temperature conditions. Deviation from ideal or predicted performance can help identify performance issues and ensure quality installations.
