The I-V curve is a graphical representation of measured current(I) and power as a function of voltage(V). I-V curve tracing is integral to your evaluation of PV module performance vs the expected performance. It is also used to define degradation in power output. The module manufacturer will specify a linear output decline that is expected which can then be compared to actual measurements. As the asset owner you can rest assured that your investment is protected by performing this critical analysis. It is imperative to have a consistent PV module screening with I-V curve tracing. This not only helps the asset owner to manage the quality assurance of the PV modules but also ensures it is able to provide the most power generation possible from your investment.
I-V curve tracing is also extremely useful in locating external and internal faults such as a damaged solar cell, shading or soiling, increased temperatures, or defective bypass diodes.
