Photovoltaic solar power for a wastewater electrocoagulation prototype

A photovoltaic solar power supply is presented; it supplies energy to the electrodes of a wastewater treatment prototype by electrocoagulation. The source will be able to supply three voltages levels 10, 20, and 30 volts, with a current of 1000 mA. The system consists of an array of solar panels and Nickel Metal batteries. The amount of energy to be supplied by the solar panels is estimated, the level of storage in batteries is calculated and fed to the electrocoagulation system. The results of an experiment that operates independently of the power supply line and that works in rural areas are presented.
