Design of a solar tracking controller based on the 89C51microcontroller

According to the operating principle of composite control generally applied for solar tracking control,an embedded solar tracking controller was designed using the inexpensive and low-power 89C51 MCU to meet the requirements of composite control.The AD converter module and communication module with PC were integrated into the tracking controller in order to realize the sensor control and clock control functions.Tests on the performance of the concentrator equipped with the newly-designed controller and the fixed-type condenser were carried out under the same experimental conditions.The test results showed that the receiving rate of the concentrator equipped with the newly-designed controller is increased by about 35% in comparison with the fixed-type condenser.In addition,the newly-designed controller enhances greatly the tracking ability and stability of the solar installation.
