A support system for photovoltaic cells upon a roof. A cell support structure is provided beneath each cell, such as in the form of a pair of brackets to form a photovoltaic panel. The panels overlap partially to function somewhat as shingles, to shed water off of the roof. A lower side wall of each photovoltaic panel has at least one port therein to selectively access a space beneath the photovoltaic cell. Photovoltaic cell electronics, such as an inverter for one or a series of cells. A door is provided in one embodiment which selectively covers the port and acts as a support for the photovoltaic cell electronics.

A barrier, such as a PV module, is secured to a base by a support to create a shingle assembly with a venting region defined between the barrier and base for temperature regulation. The first edge of one base may be interengageable with the second edge of an adjacent base to be capable of resisting first and second disengaging forces oriented perpendicular to the edges and along planes oriented parallel to and perpendicular to the base. A deflector may be used to help reduce wind uplift forces.

This invention describes a non-imaging, non-tracking, integrally-formed solar radiation concentrator that passively concentrates both diffuse and direct solar radiation onto photovoltaic cells to produce electricity, incorporating its features into a shingle-like element useful as a roofing material and in other structural applications. The substantially transparent, solar concentrating elements of the invention may also incorporate a system to remove waste energy in the form of heat that is not utilized in the generation of electricity. The invention further provides a thermal energy recovery system including a forced convection air system for removing waste heat from the concentrating shingle assembly and using it, if desired, for building space heat or domestic water heating.

The present invention relates to low-cost, efficiently-manufactured, polymer-based products useful as roofing shingles and similar products. The inventive shingles are weatherproof, inexpensive to manufacture and durable, particularly as contrasted with conventional shingles in areas of the country subject to hail damage. The invention also includes a method of making such shingle products. In a preferred embodiment, products of this invention use rubber material as the polymer base in combination with specific types of polyolefins. The rubber material can be most efficiently provided by the use of crumb rubber particles from spent automobile tires and other recycled rubber debris which are readily available and of very low cost. The products will have an average life far greater than that of current commercial roofing shingles, which are made using fiberglass or asphalt.The products of the instant invention are produced by extrusion as a mixture of materials, which product and its materials can be summarized as follows as a roofing shingle product which comprises:a. one or more side-branched polyolefins as an elastomer;b. optionally a blend of additional synthetic polymers, such as ethylene and propylene, as a second elastomer; andc. a rubber fraction, preferably obtained in part from recycled spent automotive or truck tires, and similar sources of waste rubber (sometimes known as "crumb rubber"), ground or recycled into particles having a mesh size of from 10 to 30 (i.e., approximately from about 500 to about 1000 microns).

A fastener-free composite roofing product comprising a roofing material and an interply material attached to the roofing material, wherein the interply material includes an adhesive coating on one side. The interply material is attached adjacent to an edge of the roofing material to permit a major portion of the interply material to be folded away from the roofing material for application to a roof. The adhesive is effective to secure the roofing product to the roof without the use of nails or other fasteners. The roofing material may be a roofing shingle or roll roofing, and the interply material is comprised of a water resistant material.

The disclosed embodiments and principles provide a way to integrate high-efficiency, low-profile power electronics with localized maximum power point tracking (MPPT) into a rooftop shingle-based photovoltaic power system. DC-DC power converters having a height, or profile, as low as ¼ inch for a 200 W power output, are able to be included in a building-integrated photovoltaic (BIPV) roof shingle. The DC-DC power converters increase the relatively low voltage produced by two rows of series-connected photovoltaic shingles, each including photovoltaic cells, to a high voltage used by a DC-AC inverter. For example, DC-DC power converter increases the voltage produced by two rows of series-connected photovoltaic shingles from several tens of volts to approximately 400 volts. Thus, the DC-DC power converters provide a large voltage step-up using a low profile and with very high efficiency.

An asphalt-based roofing material includes a coating having a top portion containing a mixture of asphalt and igneous and / or metamorphic rock particles, while the mat portion of the coating contains a mixture of asphalt and a filler which contains less than 10% igneous and / or metamorphic rock particles. In other embodiments, the top portion but not the bottom portion of the coating meets or exceeds a pliability standard, passes a weathering performance test, or has a high solar reflectance. In another embodiment relating to a laminated roofing material, the top portion but not the bottom portion has viscoelastic properties effective to prevent the coating from sticking to an adjacent shingle in a bundle. The invention also relates to a continuous process of applying first and second coatings to a mat for manufacturing a roofing material. In a first coating operation, a first asphalt-based coating is continuously applied to a first surface of the mat so that the first coating saturates the mat and forms a layer on the first surface. In a second coating operation, a second asphalt-based coating is continuously applied to a second surface of the mat so that the second coating forms a layer on the second surface. The second coating has different properties from the first coating.

A fire resistant PV shingle assembly includes a PV assembly, including PV body, a fire shield and a connection member connecting the fire shield below the PV body, and a support and inter-engagement assembly.

The upper interlock element of one PV shingle assembly is inter-engageable with the lower interlock element of an adjacent PV shingle assembly. In some embodiments the PV shingle assembly may comprise a ventilation path below the PV body. The PV body may be slidably mounted to the connection member to facilitate removal of the PV body.

A multiple-layer laminated shingle and a method of making the shingle are provided, in which at least one adhesive of high temperature resistance is applied for securing the shingle layers together, to reduce reliance on a roofer having to fasten (via nails, staples or the like) through a narrow headlap zone of a posterior shingle layer in order to secure the posterior shingle layer to a roof, such that a vertically wide portion of the headlap area of the anterior shingle layer is presented to the roofer as a nailing zone.

Embodiments are directed to using a hash signature of a rendered DOM object of a website to find similar content and behavior on other websites. Embodiments break a DOM into a large number of data portions (i.e., “shingles”), apply a hashing algorithm to the shingles, select a predetermined number of hashes from the hashed shingles according to a selection criteria to create a hash signature, and compare the hash signature to that of a reference page to determine similarity of website DOM object content. Embodiments can be used to identify phishing websites, defaced websites, spam websites, significant changes in the content of a webpage, copyright infringement, and any other suitable purposes related to the similarity between website DOM object content.

A shingle formed from a base sheet, with a layer of polymer modified asphalt coating the top of the base sheet, and a layer of conventional oxidized asphalt, free from polymer additives, coating the bottom of the base sheet. Both layers preferably directly contact the strands of the base sheet for good adhesion. This improves the strength, flexibility and ultraviolet resistance of the shingle, while reducing the cost as compared with a shingle which utilized only polymer modified asphalt, and in addition it increases the stiffness of the shingle as compared with one using only polymer modified asphalt.
