Abstract
Described herein are solar energy collector systems, components for solar energy collector systems, and methods for installing solar energy collector systems. The components for solar energy collector systems include but are not limited to solar radiation absorbers, receivers, drives, drive systems, reflectors, and various support structures. The solar energy collection systems, solar radiation absorbers, receivers, drives, drive systems, reflectors, support structures, and/or methods may be used, for example, in LFR solar arrays. Drives and drive systems are described herein that may provide improved rotational positioning, movement, and/or rotational positional sensing. For example, drives and drive systems are provided which allow operation through a variable frequency drive. The components and methods described herein may be used together in any combination in a solar collector system, or they may be used separately in different solar collector systems.
