Solar Panels Wired In Series

When solar panels are wired in series, the array’s voltage is added together while the current (or amps) stays the same.

In the diagram above, 4 x 100w panels, each with a rated voltage of 17.9 and current of 5.72A

Wired In Series

Wired in series could produce 71.6 volts and 5.72 amps – a total of 409 watts

Solar Panels Wired In Parallel

A parallel connection is created when the positive terminal of one panel is connected to the positive terminal of another
