Abstract: A solar power generation device comprising a power subunit comprising an array configured to collect solar radiation, and a control subunit removably connected to the power subunit and configured to provide control and motion to the power subunit. The array includes at least one solar module and a pivoting means configured to facilitate movement of the at least one solar module from a closed configuration to an open configuration. The power subunit includes a frame configured to support and move the array. The control subunit includes a tracking system configured to position the array relative to a the sun to maximize collection of solar radiation. When not in use, the solar power generation device may be stacked in a closed configuration with other similar devices on a pallet or other storage device.
