A swivel and fanning drive for solar panels, including a base support, a swivel plate mounted pivotingly about a horizontal axis, and a plurality of solar panels that can be fanned in and out about a fan-out axis. The swivel plate can be pivoted by at least one crank and connecting rod. Pivotal movement of the swivel plate about a vertical axis can cause the solar panels to be fanned-in or fanned-out. A brake can resist movement of the solar panels about the fan-out axis.
