A Dual Axis Active Solar Tracking Device
The green energy also called renewable energy has gained much attention nowadays. Some renewable energy types are solar energy, hydro potential energy, wind energy, biomass energy and terrestrial heat. Among these, solar energy is effective that can be used. Nowadays, the solar panels are popular and are often used to convert solar energy into electricity. Mostly, solar panel that exists and used now is static, it cannot generates higher power. The solar panel should always be parallel to the sun in order to get more sunlight. This project attempts to generate more power from sunlight using solar panel tracking. If the solar panel is parallel to the sun, that the power generated from the solar panels will be maximum. Therefore, this project is concerned with the position of the solar panel. This system consists of hardware, electrical and software development. The stand was created and combine the stepper motor with the stand. A photoresistor have been used as a sensor to detect a sunlight. Then, the stepper motor and sensor circuit are connected with the microcontroller. Lastly, develop a program to control the sensor and stepper motor and burn the program in Arduino. The goal of this project is to develop a system of automatic sun tracking position. The system will move the solar panel angle to keep in parallel with the sun and generate maximum power at all times. In this project, a dual axis active solar tracking device is presented. A dual axis active solar tracking system changes both azimuth (horizontal) and altitude (vertical) angle of solar panel. It is believe that, A dual axis solar tracker system are more efficient and generates more power than fixed solar panels. There are a few recommendations for the future work of this project. The newly developed sensor can be reduced in size. Smaller sensor is useful if the sensor is going to be produced in higher quantity. The overall design can be improved for better and attractive appearance for the user.
