How to String Solar Panels: Wiring Basics to Learn
Stringing is the process of wiring the solar panels together and connecting them to the inverter. It’s important to get the configuration right to prevent the inverter from getting damaged due to high voltage or underproduction due to less voltage.
Many people ask about solar stringing is the number of panels they can string together as a single input into the inverter. The solar strings are combined as a unit in the Solar combiner box connected to the inverter.
The process of stringing solar panels is tricky and extensive. We’ll look at the basics and try to understand the most vital aspects before delving deeper into the subject.
Voltage, current, and power are the three crucial terms you need to understand to learn how to string solar panels for maximum efficiency.

Types of Solar Stringing
You can either go for series stringing or parallel stringing when connecting the panels to the solar combiner box.
As the name suggests, the solar panels are connected in a line, the previous to the next, and so, on until the end. The positive terminal of the previous one is connected to the negative terminal of the next in a straight line from one end to another. Even though each panel adds more voltage to the series, the total current output remains the same. You cannot opt for series stringing if you want more current generated by the solar panel string.
Parallel stringing is slightly complex than series stringing. Here, the positives of all the panels are connected to one wire and the negatives to another. This results in increased current even though the total voltage remains the same. You need to choose the type of solar stringing based on the voltage capacity of the inverter and the current you want to generate.
