Abstract: Disclosed herein are novel slew drive components and systems. In some cases, a slew drive system can comprise a sensor configured to measure deformation in a deformation element of a sensor carrier component, which can result from axial displacement of a worm gear of the slew drive system. In some cases, measured deformation of a deformation element can be used to determine torque applied to a worm gear by a slew drive worm wheel, as described herein.

Abstract: A photovoltaic device can include a module and a rail. The module can have an edge formed around a perimeter of the module. The rail can include a coupling surface at a top side of the rail, and a recessed surface offset from the coupling surface and towards a bottom side of the rail.

Abstract: A frameless housing composed of plates forming housing walls. Each plate is inwardly bent a number of times towards the inside of the housing along its side edges, possesses bevel-cut corners and the multiple angled or bent edges are each provided with a hollow channel-shaped section formed by bending, said section adjoining the associated plate side edge. A connection section bounds at the channel-shaped section and extends at an angle of approximately 45.degree. towards the inside of the plate. Upon interconnecting each two plates which abut one another at right angles at their connection sections a sealing member can be clampingly held between the channel-shaped sections which confront one another.
