This project aims to develop a heliotropic system that enhance the performance of panels. It achieves this by using Light Dependent Resistor (LDR) sensors to detect sunlight intensity. Since the orientation of panels significantly impacts the amount of energy they collect, this system incorporates four LDR sensors positioned in different directions--North, South, East, and West. These sensors monitors sunlight levels from various angles, ensuring optimal positioning for greater energy absorption. The goal here is to design a heliotropic tracker that improves the panels performance using light sensors called Light Dependent Resistors (LDRs). It's well-known that light travels in straight lines from its source. In solar power systems, the alignment of solar panels with the setting sun is vital for maximizing energy capture. To achieve this, the project uses four LDR sensors arranged in a cross configuration, each facing North, South, East, and West. This is accomplished with the help of three servo motors that allow the solar panels to rotate. These motors control the horizontal (East-West) and vertical (North-South) movements, as well as the tilt of the system panels in relation to the sun's position. An Arduino microcontroller will manage the servo motors, directing the movement of the system panels based on the data received from the LDR sensors.
