*4.6. Power and Voltage at GMPP*

In addition, when compared to traditional SP, TCT, SDK and SM configurations, I-SDK setups produced more power at GMPP of 127.9 W.

Under shading case-IV, the SP, TCT, SDK, I-SDK and SM setups had different voltages at GMPP (52.90 V, 59.97 V, 59.36 V, 58.34 V and 58 V). Figure 22 is a bar chart depicting the power and voltage at GMPP.
