When solar panels are connected in series, they produce a higher voltage than when not connected because each panel's individual voltage is added onto another as electrical current flows from one panel to the next through the stringing wire.
What happens if you install solar panels in series?
When installing solar panels in series, the voltage adds up, but the current stays the same for all of the elements. For example, if you installed 5 solar panels in series – with each solar panel rated at 12 volts and 5 amps – you'd still have 5 amps but a full 60 volts. There are some major benefits to connecting solar panels in series.
