Abstract: Renewable energy sources are very attractive energy sources due to their abundant available nature, highly clean energy source because of their environmental friendly nature and cheap continuous nature. However, because of their intermittent available property, hybrid renewable energy sources are used to counter this drawback. In this study, the reliability of a hybrid renewable energy complex system with five components subsystem is evaluated. The reliability of the components is assumed to follow the Weibull failure laws. The reliability of the system is determined using the Event Tree approach. The effect of operating time (t), failure parameter (λ) and repair parameters (β) are shown both graphically and numerically for arbitrarily value of different parameters. The sensitivity analysis was carried out to investigate the overall system reliability with the value of t ranges between 0 and 0.5, λ between 0.01 and 0.05 and β between 0.1 and 0.5. The practical realization of this study is envisioned in a hybrid renewable power system network
