Single Axis Solar Tracker

One of the most popular renewable energy sources is solar energy. Solar energy is rapidly gaining notoriety as an important means of expanding renewable energy resources. As such, it is vital that those in engineering fields understand the technologies associated with this area. My project will include the design and construction of a solar panel tracking system. The main purpose of the project is to achieve optimum energy efficiency by PV cell. We are using a PV solar cell to generate energy from Sun. But in the practical scenario of solar energy generation, conventionally we use static PV cell. So the efficiency of the total system is reduced. To achieve higher efficiency we track down the Sun. We are using LDR to sense the light. Then the sensed signals go to the comparator to compare and generate the control signal. This control signal goes to the driver circuit. This driver circuit drives the stepper motor. Stepper motor set position of the PV cell always to the perpendicular to solar beam radiation. Solar tracking allows more energy to be produced because the solar array is able to remain aligned to the sun.
