PV panel orientation control:

An astronomical clock is implemented in a PR200 controller. Angular position of the Sun is calculated based on the astronomical time and the geographical location of the PV installation. The orientation of the PV panel’s surface normal is being regulated to achieve near 0° angle of incidence.

The range of vertical movement (pitch angle) is 75°, while the range of horizontal movement (yaw angle) is 60°. The control program is designed to operate with every possible geographical location.


  • the most precise control scheme for PV panel orientation on the market, not affected by local cloudiness,
  • the PR200 controller can work with either electric or hydraulic motors.

We offer:

  • the PR200 controller with pre-downloaded control program,
  • wiring diagrams,
  • assistance with system start-up.
