The objectives of this work are to examine the causes of the breakdown in the photovoltaic power systems, to propose strategies to solve them, and to evaluate the field lifetime of some elements of the PV systems. The data analyzed were obtained from maintenance records and measurements over a period of 9 years (from 2007 to 2015)
The federal government has installed more than 2,900 solar photovoltaic (PV) systems, and the electricity generated from these on-site systems has increased 12-fold over the last 10 years. PV systems have 20- to 30-year lifespans. As they age, their performance can be optimized through conducting proper operations and maintenance (O&M).

2.1. Electrical Energy Storage (EES) Electrical Energy Storage (EES) refers to a process of converting electrical energy into a form that can be stored for converting back to electrical energy when required. The conjunction of PV systems with battery storage can maximize the level of self-consumed PV electricity.
After solar energy arrays are installed, they must undergo operations and maintenance (O&M) to function properly and meet energy production targets over the lifecycle of the
