Sizing of a photovoltaic system for water chlorination

Khouzam, Kamel Y. & Appelbaum, Joseph (2007) Sizing of a photovoltaic system for water chlorination. In ISES Solar World Congress 2007, 18 to 21 September 2007, Beijing - China.


Electrolysis takes place in a solution by an electrolytic cell usually at low voltage and high current. An example is a chlorinator used in salt-water swimming pools to produce in situ chlorine for disinfection. This paper deals with the modelling and analysis of a photovoltaic (PV) electro-chlorination system and compares the amount of electric charge and chlorine output delivered to systems when operating with and without a maximum power point tracker (MPPT). Results show that good performance of the electrolytic system load is obtained if the intersection is to the left of the maximum power locus of the PV array. Based on this property a simple rule of sizing the PV array may be adopted. Using an MPPT in the system would be advantageous to boost chlorine production. Field trials indicated that the daily and seasonal variations in solar radiation and ambient temperature match well the need for chlorine production during the day. It is believed that the application of PV into salt-water chlorination is an effective way to semi-automate the chlorine supply into swimming and spa pools and would save cost.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
