A solar tracker enables the construction of independent power sources and a micro-grid. The mechanism of the land-intensive system has two independent virtual axes for azimuthal moving and altitude moving. After the solar panel is aligned, the tracker drives it to move from east to west until the amount of change of the Sun’s altitude reaches a specific level.The tracker has an opening system of solar modules to reduce a lateral force by wind and a normal force by snow accumulation. When wind reaches a specific level at any tracking angle of the solar panel, the tracker opens some or all of the solar modules so that wind passes. Joints composing the two virtual axes have a locking system to secure the stability of the structure. Clustered actuators demonstrate long stroke and significant power, allowing the tracker to be built as a structure.
