Design of Solar Photovoltaic Based Portable Water Filter

Abstract

In this work, a hardware model of solar photovoltaic system-based water filter is designed to support the Qatrah program of Kingdom of Saudi Arabia. A solar photovoltaic system provides active energy to charge the battery of 24 Volt via dc to dc boost converter (step-up converter) and battery energy is used to run the dc pump of water filter in remote areas. A boost converter increases the input voltage level of solar panel upto 25 Volt fix to run the dc motor of solar pump and at same time it charges the batteries in sun light. The boost converter switch is pulsed at maximum output power of solar. It is extracted using maximum power point tracking (MPPT) system. An Arduino Nano microcontroller is used to extract the pulse of dc to dc boost converter at MPPT of solar photovoltaic system.
