This paper is concerned with the probabilistic sizing of Photovoltaic systems supplying power to remote offshore loads. Utility services of offshore facilities may be supplied from either commercial or industrial (in-house generation) utilities. In the case of commercial supply, the power is supplied from the nearest onshore substation through submarine cables. Also, the sizing of Photovoltaic (PV) power systems for remote offshore loads has been the concern of end users. This is because of the space constraints associated with the application and the expensive cost of panels and batteries. This paper evaluates the design of the PV system using three probabilistic methods. One is considering fixed days of battery back up and recharge and the other is based on loss of load probability (LOLP). The third is based on Markov Chain Modeling. LOLP distinctly shows reduction in the number of panels and size of batteries while providing a detailed view of the system performance.
