Answer :

Final answer:

Low Sun conditions in PV systems can result from various issues including malfunctioning PV modules, faulty PV links, and open circuits.


Explanation:

Low Sun conditions in photovoltaic systems can be caused by several factors:

  • Malfunctioning PV Module: A defective PV module can lead to reduced power output during low sun conditions.
  • Faulty PV Link: Issues with the PV link can also contribute to decreased performance under low sunlight.
  • Open circuit in the array: An open circuit within the array can prevent proper current flow, impacting system efficiency during low sun exposure.
