Just like a battery, solar panels have two terminals: one positive and one negative. When you connect the positive terminal of one panel to the negative terminal of another panel, you create a series connection.

The voltage connected in series with solar panels can vary widely based on the specific configuration and applications, but several key points should be noted: 1) **Solar panels are typically rated between 18 to 36 volts each, 2) Connecting panels in series adds their voltages.
