Solar Photovoltaic Application for Contributing Power Supply of Community Clean Water Provider

Abstract

The need of clean water for human daily life is about crucial. Due to the inadequate capability of government water supply company, it is becoming common for a community to establish their own water supply system. This includes a deep well, high water reservoir, and submersible pump. The pump is normally supplied with power from electricity grid. The extensive availability of sunlight may be used to generate electric power using Solar Photovoltaic (PV) panels for supplying power for the pump. This paper presents the application of Solar PV panels to generate power that contributes power for the pump at the system of clean water provider. A 1000-WP solar panels system is employed to generate the voltage and a 60-A MPPT is used to regulate the voltage for supplying 2 x 150-Ah Li-ion battery. A 3000-W inverter is used to provide AC power for 3-hp 220-V pump. Considering the capacity of Solar PV panels and the continued availability of sunlight, the hybrid supply for the pump is established. This integrates the supply from solar PV and utility grid controlled with Automatic Transfer Switch (ATS). This determines the power supply for the pump either from Solar PV or electricity grid. This system is implemented in the community water supply at Sidomulyo, Krikilan, Sragen. The hybrid strategy enables solar PV to contribute supplying power for the pump and reduce the need of power from utility.
