Automatic solar tracking with MPPT

Abstract

The project deals with use of alternative energy resource for power generation which can be used to supply power in domestic application. Solar energy is a very large, inexhaustible source of energy and Green Energy System. Solar energy has a major advantage for no impure outlets but problem associated with solar is less efficiency and high cost. The power from the sun intercepted by the earth is approximately 1.8x1011MW, which is many thousand times larger than the present consumption rate on the earth of all commercial energy sources. Solar tracking system can be used as a power generating method from sunlight. This method of power generation is simple and is taken from natural resource. This needs only maximum sunlight to generate power. This project presents for power generation and sensor based solar tracking system to utilize the maximum solar energy through solar panel by setting the equipment to get maximum sunlight automatically in real time. This proposed system is tracking for maximum intensity of light. When there is decrease in intensity of light, this system automatically changes its direction to get maximum intensity of light. The proposed method is to design an electronic circuit to sense the intensity of light and control the DC motor driver for the panel movement, and construct a Buck- Boost converter for to step up and step-down the voltage, and store the maximum utilized output voltage in Lead-Acid Battery.
