Photovoltaic string
In plain English
What does Photovoltaic string mean?
A photovoltaic string is a defined series-connected group of modules.
A simple example
A solar drawing can identify each string before it reaches a combiner or inverter input.
What the drawings help you do
Identify the modules connected in series and label the string’s ends. A string is a connection arrangement, not a particular module product. The module choice and number in series determine the conditions that must be checked against the connected equipment and installation requirements.
- Series
- An end-to-end connection in which the connected path passes through each element.
- String
- A defined series-connected group of photovoltaic modules.
Before using this reference
- State module type and number in series.
- Identify the string’s positive and negative connections.
- Cross-reference the selected combiner, isolation and receiving equipment.
Does adding modules in series have the same effect as adding parallel strings?
No. Series connections add module voltages; parallel connections combine current paths. The complete electrical design must account for the selected modules and their operating conditions.

A distinction that matters
The number and type of modules determine string conditions; the label alone does not.
