Automatic Single Axis Solar Tracking Controller
Working principle:
Single axis solar tracking controller is a device that controls the
PV modules so that the solar light shines vertically on the PV
modules as much as possible. The tracking controller use the
astronomical algorithm to calculate the position and angle of the
sun, and the inclination of the solar equipment is measured by the
inclination sensor, and the error of the two angles is compared to
control the motor forward or reverse, so that the equipment can
accurately aim at the sun. HWL tracking controller can
significantly improve the efficiency of the power generation.
