Solar Water Heater, Household Water Heating, Glow Plug Heating, Energy Storage, Temperature Sensor

This work presents the design and simulation of solar water heater for household use. The purpose is basically to harness solar energy to provide heated water, aimed at reducing reliance on conventional energy sources and lower cost of energy for households. The work involves the installation of a 20W solar panel, connection of 18650 Lithium batteries to store solar energy, integration of glow plugs into the water reservoir for heating, installation of a switch for user control, placement of a temperature sensor for monitoring, setup of the water reservoir and testing and calibration of the entire system. The result produced one that is cost-effective and efficient solar water heater that provide heated water for household needs. And from all indication this can offer sustainable solution for household water heating, contributing to energy conservation and support a net zero environmental.
