Abstract

The global energy shortage, especially in developing countries, drives the search for alternative energy sources such as solar power, which is one of the cleanest energy sources. This research discusses the comparison of efficiency between solar PV fixed, single-axis solar trackers, and dual-axis solar trackers. The method used is a survey of the literature of multiple studies that only analyzes the efficiency of solar PV using different tracking devices. The efficiency data is normalized based on location factors and light intensity for a fair comparison. The results show that fixed solar panels are stationary and simple, serving as a baseline with 100 % efficiency. Single-axis panels track the sun horizontally, boosting efficiency by 25.6 % but with moderate complexity due to motors and controls. Dual-axis panels track the sun both horizontally and vertically, increasing efficiency by up to 50 % but with the highest complexity due to more moving parts and dual-axis control systems.

Abstract

Water resource management is a critical aspect of various sectors, including agriculture, industry, and household applications, where maintaining optimal water levels is essential for efficiency, sustainability, and safety. Traditional water level control methods often rely on manual operations, leading to inefficiencies, resource wastage, and potential system failures. To address these challenges, this study presents the design and implementation of an automated water level control system using a Proportional-Integral-Derivative (PID) controller, an HC-SR04 ultrasonic sensor, and an Arduino Uno microcontroller. The system is designed to enhance accuracy and reliability in liquid level regulation, particularly in industrial and domestic settings. By systematically tuning the Proportional Gain (Kp), Integral Gain (Ki), and Derivative Gain (Kd), the optimal parameter values were determined as Kp = 20.0, Ki = 11.0, and Kd = 1.0. Experimental results demonstrated that the proposed system achieves stable water level regulation with rapid response times and minimal deviations. This research contributes to the advancement of automated liquid control technologies, offering a cost-effective and efficient solution for real-world water management applications.
