A non-invasive roof attachment system for attaching structures to residential and commercial roofs without the use of penetrations to roofing shingles and sealing layers is described. The attachment system includes vertical and lateral array stays to attach roof mounted systems such as solar panels. The non-slip attachment system also allows for the quick removal of such roof mounted systems rapidly and without the need for repair of penetrations. The non-slip attachment system uses, among other things, an array-stay retainer comprising a vertical member and a horizontal member. A high friction foam polymer padding may further secure the array stays to the roof.

In various representative aspects, an assembly for securing array skirts and solar panel modules in an array on a roof by providing a leveling system that utilizes a barrel bolt and barrel nut to vertically adjust the assembly. Improved electrical bonding by utilizing bonding pins installed in mounting plates of a support clamp are also provided. Additionally, an improved array skirt design that is installed on the outer row of the array, as well as improved designs in the support clamp and splice mechanisms are also provided. Finally, an improved wire management system is included as well as a method of installation of the array assembly.

In various representative aspects, an assembly for securing a solar panel rail and rail-less support structures to a shingle roof. More specifically, the apparatus includes a connection bracket and flashing device for use in installing solar panel rail support structures. The connection bracket is secured to the flashing device by rotating its base around a threaded connection until it locks in place so that a solar panel rail support guide can be connected to a generally U-shaped connection on the top of the bracket. The apparatus also offers an improved means to cover the penetration point on the flashing to protect it and prevent water from leaking into the roof as well as an improved way to install the apparatus over existing products. An alternate embodiment of the apparatus is offered to support a rail-less pivot mount as well.

A solar roof of a building includes a plurality of solar panels removably coupled to a roof of the building such that a first solar panel of the plurality of solar panels is configured to be removed from the roof without removing an adjacent solar panel.

At least one solar tracker has a rotating structure, which supports bifacial photovoltaic solar panels, in order to provide the panels with a solar tracking rotation around, at least, a non-azimuth axis of rotation; and a control unit which commands the tracker; and an albedo reflector arranged on the ground on one side or on both sides of the solar tracker with respect to the non-azimuth axis of rotation, next to the tracker itself, wherein the albedo reflector in turn comprises a reflective membrane which reflects albedo radiation towards the panels. Albedo radiation is optimally harnessed.

A roof integrated photovoltaic system includes a starter bar having a foot base and configured to be installed to a roof deck, a plurality of water shedding layers, and a photovoltaic module. One of the plurality of water shedding layers is configured to be installed over the foot base of the starter bar, and one of another of which is configured to overlap and be installed over the one of the plurality of water shedding layers. The system further includes a foot module configured to be attached to an upper portion of the photovoltaic module. A lower portion of the photovoltaic module is configured to align with the foot base of the starter bar, and the foot module is configured to be affixed on a last overlapping layer of the plurality of water shedding layers to the roof deck.
