RENEWABLE ENERGY MONITORING AND HARVESTING USING IOT (SOLAR ENERGY)

CHAPTER ONE

INTRODUCTION

1.1 Background of the Study

The global energy crisis and the need for sustainable development have driven significant interest in renewable energy sources, particularly solar energy. Solar energy, derived from the sun’s radiation, is one of the most abundant and promising renewable energy resources, contributing to the global energy transition from fossil fuels to greener alternatives (Abdullah et al., 2022). Technological advancements in photovoltaic (PV) cells have improved the efficiency of solar energy harvesting, making it a viable option for both small-scale and large-scale energy production (Li et al., 2023).

The integration of Internet of Things (IoT) technologies into renewable energy systems has emerged as a powerful tool for monitoring and optimizing energy production and consumption. IoT-based systems enable real-time monitoring of solar energy output, predictive maintenance, and efficient energy management, leading to enhanced operational efficiency and cost reduction (Ahmed & Zhang, 2021). These systems leverage sensors, actuators, and cloud-based data processing to provide critical insights into the performance of solar energy systems, ensuring reliability and scalability (Yao et al., 2023).

 

Despite the potential of solar energy, many systems face challenges such as inefficient energy harvesting, limited monitoring capabilities, and lack of real-time data analysis, which hinder their effectiveness (Zhou et al., 2022). Therefore, the integration of IoT in solar energy systems offers a solution for optimizing energy harvesting and improving system efficiency through automated monitoring and control.

1.2 Statement of the Problem

While solar energy is recognized as a key solution to the global energy crisis, there are several challenges in its widespread adoption. Solar energy systems often face inefficiencies in harvesting, especially in regions with fluctuating sunlight. Furthermore, the lack of continuous and efficient monitoring of solar energy systems leads to reduced performance and energy wastage (Wang & Liu, 2022). Without proper monitoring, systems are more prone to downtime and degradation, resulting in increased operational costs and reduced energy output.

The integration of IoT technologies presents a potential solution to these challenges, offering improved real-time monitoring and predictive maintenance to maximize energy harvesting. However, the implementation of IoT-based monitoring systems for solar energy is still in its early stages, and there is limited research on how these systems can be optimized for maximum efficiency and cost-effectiveness in renewable energy applications (Chen et al., 2021). This study seeks to address these gaps by exploring the potential of IoT in enhancing the monitoring and harvesting of solar energy.

Additionally, the study will contribute to the growing body of knowledge on the integration of IoT and renewable energy systems, offering practical solutions for improving energy management and sustainability (Zhang & Ali, 2023).

Furthermore, this research is timely, as global efforts to reduce carbon emissions and transition to cleaner energy sources are accelerating. The results of this study could serve as a foundation for future developments in renewable energy systems and IoT applications, particularly in emerging economies where solar energy plays a crucial role in energy security (Akpan & Johnson, 2023).

The scope of this study is focused on the design, implementation, and evaluation of an IoT-based system for solar energy monitoring and harvesting. The study will involve the use of sensors, communication protocols, and cloud-based platforms to enable real-time data collection and analysis. However, the study is limited to solar energy systems, and the findings may not be fully generalizable to other renewable energy sources such as wind or hydropower. Moreover, the study will be conducted using a prototype system, which may not fully capture the complexities of large-scale solar energy deployments. Additionally, financial and time constraints may limit the scope of data collection and system testing.
