In this example, the series string will have no losses.

How many volts is a series string?

When wired in series, the resulting series string will have a voltage of 42 volts (12V + 14V + 16V) and a current of 6 amps (the lowest current rating of the 3 panels). In this example, our series string will have some power losses because the currents of the 12V/8A panel and 14V/7A panel will get "pulled down" to 6 amps.

What happens if a solar panel is wired in series?

When wired in series, the 3 connected panels (often called a series "string") will have a voltage of 36 volts (12V + 12V + 12V) and a current of 8 amps.
