The reliability of photovoltaic (PV) systems refers to the ability of these technologies to dependably produce power over a long and predictable service lifetime. The ability to stand up to a variety of weather conditions also contributes to the reliability of these systems.
Tom Key, Electric Power Research Institute. Distributed photovoltaic (PV) systems currently make an insignificant contribution to the power balance on all but a few utility distribution systems.
The advent of low-voltage ride through requirements [32, 33] signaled a change in utility perspective towards large wind, and many utilities with PV experience are suggesting that a similar change in perspective needs to follow for PV and other DG as they reach high system-level penetration.
