Rotating solar panels to follow the Sun : r/solar
Rotating solar panels to follow the Sun . You COULD do a DIY 2 axis (N-S & E-W) But by the time you get the actuators to tilt the array, the sensors and control circuit to tell the actuators where to tilt the array you may well have spent the equivalent of a few more panels/racking. The vast majority of the 2 axis mounts I''ve seen are
