Abstract: Systems and methods are provided for rotatably mounting and locking solar (e.g., photovoltaic) panels. For example, the solar panels can be mounted so as to be rotatable about an axis so as to track the sun over the course of the day, and can be locked in a suitable position during high-wind conditions. A drive mechanism includes a drive shaft, pinion gear coupled to the drive shaft, and arc gear coupled to a solar panel, and a locking mechanism includes a lock plate coupled to the arc gear and including a reaction surface. The pinion gear includes a bearing surface. When the drive shaft rotates a first amount, engagement between pinion gear teeth and arc gear teeth rotates the arc gear. When the drive shaft rotates a second amount, the arc gear rotates to a stow position where the reaction surface bears against the bearing surface, locking the arc gear.

Abstract: A solar energy collection system can include support devices made with bearings formed from sheet material. These bearings can be optionally formed so as to provide tool-less connections to their associated bearing housings. The bearings can be formed with an open configuration allowing a shaft to be inserted into an open bite of the bearing. Optionally, the bearing can be made from an ultrahigh molecular weight polyethylene plastic material. Additionally, two open-type bearing assemblies can be mounted axially offset and opposed to one another.
