摘要

This paper presents an efficient and low-cost solar tracking system designed to enhance photovoltaic energy conversion. Utilizing operational amplifiers for optimal insolation incidence detection and DC-geared motor control, the system maximizes solar panel exposure. Addressing the issue of dust accumulation, a novel manual cleaning system employing a perforated pipe and pump is integrated, enabling rapid panel cleaning, which also enhances the power output. The proposed design eliminates programmable devices, ensuring technically minimal design and affordability. Experimental results demonstrate improved energy generation compared to fixed panels. In alignment with the sustainable development goals, this work highlights a practical and user-friendly solution for optimizing solar panel efficiency, contributing to the wider adoption of sustainable solar energy as a viable alternative to use of non-renewable energy coming from environmentally questionable processes.
