Abstract

The management of an Internet of Things (IoT)-based water system powered by solar energy faces significant challenges in achieving high power efficiency and long-term thermal reliability. The objective of this study is to identify the most optimal hardware configuration that balances specific energy efficiency (ηspecific) with minimizing thermal energy dissipation in a DC water pumping system. The methodology employed is a comparative experiment that tests six different scenarios, varying the topology of the voltage regulator (Linear Regulator and Buck Converter) and the pump actuator, with a total of 30 pumping cycles at a fixed water volume of 30 litres. The processing of data was undertaken through the utilization of descriptive statistical analysis and Standard Deviation (SD) on the parameters of Power, Temperature, and Water Discharge to measure stability. The findings indicated a critical trade-off between peak energy efficiency and operational stability. Scenario 4 (12V Relay and Mini 560 Buck Converter) emerged as the most optimal configuration, recording the highest Specific Energy Efficiency (1.94 Ws/L). This superiority is evidenced by its excellent thermal stability (36.88°C), which is comparable to that of low-power configurations. In contrast, although Scenario 6 (Synchronous Buck, 51 mm Pump) demonstrated the highest operational stability (Power SD=0.02111), it compromises pumping speed. It is concluded that the implementation of the Mini 560 Buck Converter is imperative in achieving a balance between energy savings and minimizing thermal dissipation, thereby rendering it an ideal selection for solar-powered Smart Energy systems.
