Figure 2: Power Curve for a Typical PV Cell. Figure 3: I-V Characteristics as a Function of Irradiance. PV cells are typically square, with sides ranging from about 10 mm (0.3937 inches) to 127 mm (5 inches) or more on a side. Typical efficiencies range from 14% to 18% for a monocrystalline silicon PV cell.
