How Are Solar Panels Wired?

Normally, you’ll need multiple solar panels to harness sufficient solar energy that can power up your home. The basic options are parallel and series connection. In advanced setups, these circuit configurations can be combined.

What is the series connection?

When wiring solar panels in series, electricity travels through one path. Each solar panel is connected to the next using solar cable. Think of it as the string lights wherein all light bulbs are connected to each other with one wire. It’s the same with solar panels.

The solar panel wire runs from one panel’s negative terminal than to the positive terminal of the next panel and so forth until all the units are connected. Series wiring creates a continuous, closed-loop.

The main difference between series and the parallel connection is the overall voltage and amperage of the circuit. In a series circuit, the voltage of each panel adds up thereby resulting in a higher overall voltage while the amps unchanged.
