Main Article Content
The solar energy is widely used in Thailand. Most of all are fixed on the roof or ground. To increase efficiency of harvesting energy, two axes solar tracking is designed and constructed. The position of the sun is detected by using four LDR sensor. Those sensors are divided by partition in order to know the light direction of the sun. Those data from the sensor are sent to micro-controller to determine the motion by fuzzy controller. The rule of controller is designed to be concerning of energy consumption. Two linear actuator is applied to rotate solar panel. Both of actuator is decoupled. Fifty watts of solar panel is applied to collect the energy. The solar tracking of this research can gain more energy than fixed panel 14 percent. The experimental results are presented and compared.
