PERANCANGAN PROTOTYPE PENJEJAK CAHAYA MATAHARI PADA APLIKASI PEMBANGKIT LISTRIK TENAGA SURYA
Abstract: Solar energy is one of the alternative energy
sources which can be used as electrical energy. As the effect of earth rotation
and revolution, it had not been optimized maximally yet. The rotation of earth
causes the sun moves from east to west every day, and the revolution of earth
causes the sun move from north to south every year. These phenomenons cause the
different intensity of sun light in every earth surface. To optimize the sun
light, the design and realization of solar tracker is very important. The solar
tracker has to be able to track the position of the sun and move the solar cell
to face the sun light. The solar tracker can move in two axis with moving type
of rotate and tilt, so it works
optimally every time. This solar tracker is designed by using photo diode as
light sensor and servo motor as actuator. The system uses ATMega8535 as control
unit which able to process signal from the sensor and resulted Pulse Width
Modulation to control servo motor moving. The testing showed this solar tracker
capable to raise the average power to 0.676 watt and the eficiency to 36,216%.
The error of tracking is 90 at heavy cloud.
