What does String mean?
Series of PV modules; in PV design it helps verify equipment ratings, wiring, and safe operating limits.
What should designers verify about String before selecting PV equipment?
In PV design, this term helps define the electrical operating envelope of modules, strings, conductors, inverters, MLPE, and protection devices. The value may look simple on a datasheet, but the design impact depends on temperature, irradiance, configuration, and the ratings of every connected component.
Practical design considerations
- Check the term against the current datasheet and installation manual, not only a product overview.
- Consider temperature, irradiance, string length, and equipment input limits before applying the value.
- Use the same units and test conditions when comparing products or calculations.
