Investigation on Solar Power System via Field Programmable Gate Array

In contemporary society, energy plays an essential role in daily life, powering applications such as lighting, heating, and other utilities in residential and educational settings. Over the past century, various energy sources have been utilized, including coal, oil, and natural gas. These energy sources are generally categorized into two types: non-renewable and renewable energy. Among the renewable options, solar energy has gained significant attention due to its capability to convert light energy into electrical energy. Consequently, solar-powered systems have been developed to harness sunlight and transform it into usable electrical power. However, the performance of solar panels is highly dependent on sunlight availability. During rainy or cloudy conditions, the energy output declines, often resulting in insufficient power to charge storage batteries. To address this issue, the proposed prototype is designed to ensure stable power delivery for safe and efficient battery charging. Furthermore, to maximize the utilization of solar energy, a buck-boost converter will be implemented to optimize system efficiency. This project aims to investigate a battery charging and discharging algorithm using FPGA technology and to evaluate the power delivery performance of the system.
