A theoretical model to study the operational conditions of Reverse Osmosis systems (RO) is presented. The model is applied to simulate the behavior of a Photovoltaic-Powered Reverse Osmosis System (PV-RO) monitored with sensors for measuring water flow, salinity, pressure voltage and current of operation. The system is powered by a PV generator with peak power of 0.81 kW. The interface of the PV generator and the motor-pump is a frequency converter, programmed to maintain the array working at a fixed voltage, chosen within the region of the maximum power. Considering the relation given by the load curve (pressure vs. feed flow rate) the permeated flow rate was determined theoretically for a givem membrane lenght. The deviation between calculated and experimental results is smaller than 14.5 %. The model can be used to determine paramenters important in the sizing of those systems.
