A Microcontroller-Based Multi-Function Solar Tracking System

Microcontroller based multi-function solar tracking system are used to drive the load using the power from the solar panel in the morning time, when during the night time it will be operated using the battery. In this study has been worked on new method to increase the power output of solar cell by moving it in during a day and seasons with detecting degree of sunlight. And one fixable mechanism with three degrees of freedom has been designed and constructed for movement the panel of solar cell by very low power hydraulic arm and electric motor. In this way a microcontroller form PIC family has been applied for sampling of solar cell output, controlling the hydraulic arm and finding the best position of panel under the sunlight. This system follows the sun like sunflower and with this way in all hours of day uses of maximum power of solar energy.
