View the Complete Application at the US Patent & Trademark Office
A tracking solar assembly includes a base, a first support and a second support. A solar panel is mountable the base. The first support may comprise a first curved, rolling surface fixed relative to the base. The first and second supports are engageable with the support surface. The first curved surface can be rolled along the support surface to move the base between first and second orientations. The base and any solar panel may have sufficient weight to be inherently stable and resist wind loads without being secured to the support surface. The invention may comprise means for biasing the base to a chosen orientation at or between the first orientation and the second orientation. The upper surface of the base may have open regions extending into the base with solar panels mounted within the open regions with the open regions acting as solar concentrators for the solar panels.
