Bypass Diode for Solar Panel Protection

As the three PV cells are connected in series, the generated output current (I) will be the same (assuming the cells are evenly matched). The total output voltage, V T will be the sum of all the individual cell voltages added together. That is: V 1 + V 2 + V 3 = 0.5V + 0.5V + 0.5V = 1.5V. Then the solar cell I–V characteristic curves of our three cells example are simply added
