Low-cost solar water heater

Abstract

This paper presents an overview of the use of solar energy for domestic water heating purposes. In addition, the results of a preliminary research to develop a low cost system for heating water using solar energy, a green energy source is also included. For the system presented herewith, the absorption of sunrays radiated heat is by means of a thermal collector. The heating and recirculation process are automatically controlled using sensors, actuators, and a Programmable Logic Controller (PLC). The results obtained indicates that the system presented have the potential to supply enough hot water to meet the requirements for domestic consumption.

Malaysia energy strategy towards sustainability: A panoramic overview of the benefits and challenges

“…Research groups at some of the five research Universities in Malaysia have been involved in solar energy research like inverters, PV concentration, solar cells fabrications and characterization, hybrid systems and energy conversion tracking systems. Some of the works undertaken by researchers in local universities are [53].…”
