Abstract

Chlorine is widely used to control algae, kill bacteria and oxidise organic matter. In this work, photovoltaic (PV) power was applied to an electrolytic cell to produce liquid chlorine using brine of sodium chloride. The amount of chlorine production depends on the electric charge and the salinity level, and for a good matching system maximum charge is obtained if the load line intercepts the PV characteristic at as high a current as possible. Based on this property, a simple rule of sizing the PV array may be based on the rated current. Analyses were made to compare the system performance with and without a maximum power point tracker (MPPT). Results show that incorporating a MPPT would be advantageous to boost chlorine production. Field testing indicated that the variation in solar radiation and temperature matches well the need for chlorine production. The use of PV in saltwater chlorination is an effective way to semi-automate the chlorine supply to the swimming pool.
