Abstract: In order to solve the problem of twoaxis solar tracker with high cost, low efficiency and difficult to spread, a new parallel mechanism of lowcost solar automatic tracker was proposed The new parallel mechanism with solar panels was used as a platform, the changes of 6 DOF position and orientation could be acquired higher tracking accuracy The gravity center of solar panels and platform center with supporting plate of the universal wheel can be solid together and the universal wheel as pivot The edge line with pulling solar panels can change the position and posture, and also the required torque is extremely small, which can reduce the tracking energy consumption and obtain more power output The experiment results show that the device has high tracking precision, low drive power consumption Compared to a typical twoaxis solar tracker, the drive power consumption of motor can be reduced more than 70%
