What is a PV characteristic curve?
Figure 1. Classification of photovoltaic technologies [18, 19, 20, 21]. The PV characteristic curve, which is widely known as the I–V curve, is the representation of the electrical behavior describing a solar cell, PV module, PV panel, or an array under different ambient conditions, which are usually provided in a typical manufacturer’s datasheet.
What is the I-V curve of a photovoltaic array?

What are the limitations of curve-fitting PV models?
Empirical-based PV models: One of the main limitations of curve-fitting PV models is that they do not fully consider the specific characteristics of the PV panel. However, these models are very useful because they are relatively simple and easy to use for reconstructing the PV characteristic curve.
What is a typical I-V curve for a PV cell?
Figure 1: Typical I-V Characteristic Curve for a PV Cell Figure 1 shows a typical I-V curve for which the short-circuit output current, ISC is 2 A. Because the output terminals are shorted, the output voltage is 0 V. For an open output, the voltage, VOC is maximum (0.6 V) in this case, but the current is 0 A, as indicated.
