Reliability, Availability and Condition Monitoring (RACM) evaluation has become a critical area of interest for researchers as the output power quality of a Photo‐Voltaic (PV) system depend on the reliability of its components. In this paper, the RACM of grid‐connected PV systems is presented. For this, the Reliability Block Diagram (RBD) technique along with the exponential probability distribution function is used. The main objective of this work is to identify the weakest subsystem of a system in order to enhance system reliability. The condition monitoring system will be helpful in avoiding the sudden breakdown and unexpected maintenance of the system. An elaborate analysis is presented for PV system beginning from the sub‐assemblies to the subsystems and then to the overall system. In addition, the subsystems are ranked based on their impact on the overall availability of the system. This is decided based on the availability importance measures. It is observed that the inverter forms the weakest subsystem in the solar system. The novelty of the proposed RACM method is that one can monitor the health status or useful life of the system regularly which is not yet explored in the literature. Most of the papers have considered that the components of PV systems are non‐repairable but in this paper, the redundancy concept is explored which helps in increasing the reliability and availability of the system. When the proposed method and the results obtained are compared to existing methods, it is discovered that the proposed work outperforms them.

With the ever-increasing load demand throughout the globe, natural renewable resources integrated into the existing network architecture for sustainable energy production are gaining considerable significance. Photovoltaic (PV) generation systems is one such technique to deal with the worldwide challenge for achieving green energy and low carbon footprint while simultaneously providing emission free electrical power from solar radiations. In this paper, we consider smart grid architecture connecting the end-users and the utility power plant with solar energy sources through an effective power optimization system. Multiple performance criteria associated with solar cell operation are evaluated and analyzed using the simulated annealing algorithm. These objectives considered for optimization include the cell saturation current, photo-generated current, material band gap, cell temperature, annualized life cycle cost, fill factor and cell efficiency. The formulated optimization conditions are specified in terms of two independent variables of cell ambient temperature and cell illumination. Moreover, the adaption of distinct values of short circuit current coefficients on the light originated current is measured. Through extensive simulation experiments, two disparate annealing procedures of fast annealing and Boltzmann annealing are applied coupled with three categories of temperature update schemes, viz. exponential, logarithmic and linear.

The current study looks into the dependability and performance of a solar photovoltaic system that is configured in series. The system's performance is measured using system strength indicators such as reliability, availability, mean time to failure, and cost measures. The system is made up of four subsystems: a 3-out-of-5 panel, a charge controller, a 2-out-of-3 battery bank, and an inverter. In contrast to some industrial and manufacturing systems, the system is assumed to operate at full capacity. In the current study, failure is classified as complete or incomplete. A complete failure occurs when any of the subsystems fails, whereas an incomplete failure occurs when a unit in the panel subsystem or battery bank fails. The system is analyzed using the linear differential-difference equation, supplementary variable technique, Gumbel-Hougaard family of copula to obtain expressions of reliability measures of determining system strength such as availability, reliability, mean time to failure (MTTF), and profit function. To illustrate the obtained results and to analyze the effect of various system parameters, numerical examples are provided. The current study is beneficial to areas with low energy consumption, such as schools and homes, in alleviating some of the challenges they face.
