A solar power system can include a rail and a solar module disposed on the rail. A clamp assembly can couple the solar module to the rail. The clamp assembly can have a clamped configuration in which the solar module is secured to the rail and an unclamped configuration. The clamp assembly can comprise an upper clamp member, a lower clamp member coupled to the rail, and a stabilization member mechanically engaging the upper clamp member and the lower clamp member. The stabilization member can prevent rotation of the lower clamp member relative to the rail when the clamp assembly is in the clamped and unclamped configurations. In the unclamped configuration, the stabilization member can be biased such that the upper clamp member is disposed at a sufficient clearance above the rail to permit the insertion of the solar module between the upper clamp member and the rail.

A rail-less roof mounting system for installing photovoltaic (PV) modules on a roof structure comprises a base mount assembly that engages with a clamp assembly and attaches to the roof structure. The base mount assembly comprises a base member having a waterproof means, a block slider, a top slider and a covering means. An elevated seal portion of a block slider includes a borehole to receive the waterproof means. A vertical engaging portion of the block slider is attached with a sliding seal member of the top slider. The clamp assembly includes a clamp member and a plate member and the clamp member is attached with a track of the top slider. The clamp member interlocks the PV modules to provide a corner-to-corner coupling arrangement, which enables the connection of PV module corners to adjacent PV module corners by sandwiching above and beneath frame members of the PV modules.

Provided herein is a floating photovoltaic solar device designed to reduce the effect of wind forces without the use of external control or power. The device includes a floating anchored frame with a means for connecting an internal corded lattice; a corded lattice suspended within the floating frame and forming a set of polygonal cells in which independently floating solar photovoltaic modules are positioned. Access for scheduled and unscheduled maintenance may be provided by a floating service gantry. The system is modular and several devices may be connected in a honeycomb-like structure.

A solar device alignment system enabling greater adjustment of solar devices during installation is provided. The alignment system enables both translational and rotational adjustments in multiple degrees of freedom, allowing solar device installers to make greater adjustments to allow greater tolerances in installing solar devices and limit the need for extensive and expensive surveying and/or redesign of the installation to account for those tolerances.

The invention includes an apparatus for mounting a photovoltaic (PV) module onto a structure where the apparatus includes a base portion, a stud portion, and a coupling portion. The coupling portion includes a male portion that acts as a spring under load and a clip portion that penetrates the PV module frame to create a grounding bond. The apparatus includes a lower jaw, shaped to pry open a groove, and a key portion that can compress to allow for tolerances. The invention further includes a clip with one or more tabs and one or more teeth. The invention further includes a replacement roof tile which includes a support structure with a horizontal flange, a vertical component, a horizontal component, a flashing with an upper surface and a lower surface, and a tile-shaped metal surface having a curvilinear shape that reflects the shapes of adjacent tiles.

A system and apparatus are disclosed including PV modules having a frame allowing quick and easy assembling of the PV modules into a PV array in a sturdy and durable manner. In examples of the present technology, the PV modules may have a grooved frame where the groove is provided at an angle with respect to a planar surface of the modules. Various couplings may engage within the groove to assemble the PV modules into the PV array with a pivot-fit connection. Further examples of the present technology operate with PV modules having frames without grooves, or with PV modules where the frame is omitted altogether.

A method comprises selecting a mounting bracket having opposite horizontal, parallel wings, and a raised portion between the wings, applying a coating of an uncured first sealant material to a first area of a roof surface above decking of the roof, the first area having an outer perimeter greater than overall area of the bracket, urging undersurfaces of wings of the bracket into the uncured sealant material, securing the mounting bracket to the roof by screws applied into the roof decking through holes provided in the wings of the bracket, and applying a second sealant material over heads of the screws on upper surfaces of the wings of the bracket.

In an example, the present invention provides a solar tracker apparatus. In an example, the apparatus comprises a center of mass with an adjustable hanger assembly configured with a clam shell clamp assembly on the adjustable hanger assembly and a cylindrical torque tube comprising a plurality of torque tubes configured together in a continuous length from a first end to a second end such that the center of mass is aligned with a center of rotation of the cylindrical torque tubes to reduce a load of a drive motor operably coupled to the cylindrical torque tube. Further details of the present example, among others, can be found throughout the present specification and more particularly below.
