Abstract
Reliability, availability, maintainability and dependability (RAMD) is an engineering tool used to address operational and safety issues of systems solar power generation have recently made a major contribution to the global growth of renewable energy sources. Researchers are particularly involved in improving the efficiency and availability of solar photovoltaic (PV) systems. In addition, an enhanced efficiency block diagram is provided to approximate the RAMD output of four functional grid-connected solar-PV systems. The objective is to develop expressions of reliability, availability, maintainability and dependability so as to predict some reliability metrics of testing the system strength and effectiveness based on the based on Markovian technique and the equations of the subsystems are derived using the Chapman–Kolmogorov method. The impact of subsystems failure and repair rates on reliability, availability, maintainability and dependability is captured. Monitoring the vital subassemblies of a PV system increases the likelihood of not only improving system availability, but also optimizing maintenance costs. Additionally, it will inform the operators about the status of the various subsystems of the system.
