In Advantech’s solar tracking solution, the ADAM-4117 measures the input voltage signals from the sunlight transmitters to detect the direction of the strongest sunlight. The sunlight information is then sent to the PEC-3240, an Intel Celeron M Embedded Motion Controller, which can control the stepper motors of the sun tracking system and easily adjust the solar plates to the correct direction of the strongest sunlight. If two transmitters detect different sunlight strengths, the PEC-3240 will calculate the sunlight strength difference to adjust the stepper motors and find the optimal position of the solar cells. Combined with the ADAM-4117, the PEC-3240 with 4-axis motion control and 32-channel isolated digital I/O enables the solar tracking systems to continuously track the relative data and optimize the efficiency of solar cell modules.
