What term describes a set of PV modules wired in series to increase voltage?

• A. System
• B. String
• C. Array
• D. Module

Answer: (B)

When PV modules are connected in series, their voltages add together while the current stays the same through each module. The set of modules that form that single path is called a string. So, a string describes multiple modules wired in series to raise the voltage. If you have multiple strings, they’re typically connected in parallel to increase current and form a larger array. Remember, a module is one panel, an array is a collection of strings or modules arranged for overall output, and a system is the complete installation with inverters, conductors, and other components.
