LDR and Arduino based Solar Tracker
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryA sustainable power source gather by solar panels in form of sunlight is converted into power which would then be able to be utilized to give capacity to electric loads. Several individual solar cells are contained by solar panels which are themselves made out of layers of silicon, phosphorous which gives the negative charge, and boron which gives the positive charge. Solar panels ingest the photons and in doing as such start an electric flow. The subsequent energy produced from photons striking the outside of the solar panel enables electrons to be struck out of their nuclear circles and discharged into the electric field created by solar cells which at that point move these free electrons into a directional flow and this is the procedure is called the Photovoltaic effect.
Project ObjectivesAbility to manually rotate the tracker with the usage of a controller alongside the overall ecliptic.
The solar panel tracks the sun from east to west mechanically for maximum intensity of light.
To consume maximum solar energy through the solar tracking panel.
Design and improve a solar panel
High performance and efficiency of Solar panels.
The current project is based on tracking solar panels. These panels change their orientation in relation to solar radiation. This orientation helps in getting the full benefit of the optimal angle between solar panels and solar radiations. This increases the efficiency and results in maximum production of energy. A custom Arduino shield, sensor holder, and code have been used in this project. Initially, the declaration of both servos is done and the creation of an object. This serves to control the servo motors. To secure the reference servo positions, the variables posx and posy have been used. The working of the motors has been established by selecting a tolerance or a constant value. On the servo object, the servos are attached to digital pins. Pin Mode is used to select analog pins as input. The setting of servos is made to mid-point or original position.
Benefits of the ProjectAfter the implementation of a solar tracking system to solar panels, the efficiency is increased by 30- 35% as compared to fix positioned solar panels.
It enhances clean and free power production.
Tracking systems can help reduce emissions and can contribute to global warming.
Able to grab the energy throughout the day.
It is significant to get viable use for working up project’s design utilizing the various kinds of software skills and to program technical connections depending on the mechanical and
technical powers.
