A rail-less roof mounting system for PV modules is described in a filed patent (Publication Number: US20230275539A1). The system includes a plurality of PV modules with four sides, where at least two opposing sides are supported by respective side frame members. Each side frame member is supported by a first and a second clamp assembly, which are in turn supported above a roof via a base mount. The base mount consists of a block slider and a top slider. The block slider has an upstanding portion with opposing ridges, while the top slider has a downwardly extending portion with a sliding groove that mates with the ridges of the block slider. A fastener secures the top slider to the block slider by securing the block slider upstanding portion within the sliding groove. The PV modules are sandwiched above and beneath the frame members using clamp and plate members.

In addition, the rail-less roof mounting system can have a downwardly extending portion with two opposing side portions. The block slider can have a first portion parallel to the roof and a second portion perpendicular to the roof. The first and second portions of the block slider can extend away from each other at an approximately 90-degree angle.

The rail-less roof mounting system can also include a third clamp assembly supported above the roof via the frame members. The block slider can have a first portion parallel to the roof and a second portion perpendicular to the roof, with an opening. The first and second portions of the block slider can extend away from each other at an approximately 90-degree angle.

Overall, this patent describes a rail-less roof mounting system for PV modules that utilizes a block slider and a top slider to securely hold the modules in place. The system offers flexibility in terms of the number of PV modules that can be supported and the orientation of the block slider.
