Embodiments of this disclosure relate generally to shingle clip systems and methods. More particularly, embodiments relate to conductive shingle clips situated so as to transfer energy converted from a transducer or semiconductor.
Traditional roofing systems typically consist of a plurality of identical roofing shingles arranged in a pattern (i.e. overlapping) across the entire roof of a structure. In this manner, traditional shingles provide for protection from the environment and may have some aesthetic effect.
With the increase of energy prices, and the subsequent increase in energy bills, there exists a market demand for energy consumers to be able to generate their own electricity, thus reducing net energy costs. Therefore, some consumers have turned to solar (also known as “photovoltaic”) panels to generate electricity. Such solar systems are often roof-mounted. With this trend, roofing professionals may need additional training and expertise, both in roofing systems and electrical systems, to properly handle and install such systems—or an electrician may be needed. Either way, another layer of cost and inconvenience is added to the system.
Accordingly, there exists a need for an easy-to-install shingle system having a transducer and hardware to transfer that converted energy; for example, a system that is easy to manufacture, install, and works with the pre-existing shingles in the market. Moreover, there exists a need for such a system to emulate traditional shingle systems to allow for ease of installation without specialized knowledge.
The following presents a simplified summary of the invention in order to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of the invention. It is not intended to identify critical elements of the invention or to delineate the scope of the invention.

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. It is to be understood that other embodiments may be utilized and structural and functional changes may be made. Moreover, features of the various embodiments may be combined or altered. As such, the following description is presented by way of illustration only and should not limit in any way the various alternatives and modifications that may be made to the illustrated embodiments. In this disclosure, numerous specific details provide a thorough understanding of the subject disclosure. It should be understood that aspects of this disclosure may be practiced with other embodiments.
Structure 1 includes a roof 2 and exterior walls 3, wherein roof 2 is supported by wall 3. As illustrated in
The roof 2 includes a support structure 5, such as pillars, internal walls, and/or cross beams or trusses. Roof 2 may additionally include an insulating material adjacent the support structure 5 to prevent electrical contact with fasteners 40 and thereby prevent potential eddy currents, hall voltages, and shorting the circuit. Situated over the support structure is a sheathing 7. The sheathing 7 is a thin flat surface which extends across the entire dimension of the roof 2. The sheathing 7 may comprise plywood, strand board, fiberglass, and the like. The sheathing 7 may alternatively be a composite substrate including a material configured to prevent voltage leaks through semi-conductive plywood or strand board substrate layers.
Situated on top of the sheathing layer 7 is an underlayment layer 9. The underlayment layer 9 is a thin surface which extends across the entire dimension of the roof 2 and sheathing layer 7. The underlayment layer 9 may be thinner than the sheathing layer 7 and may comprise felt; tar paper; Spiral cut, Double-laminated and Machine direction drawing (SDM) strength film; or the like.
Situated around the edges 8 of the roof 2 is a starter or undercourse shingle layer 10. This layer 10 may be a single set of asphalt singles laid down in a row or column without overlap, to absorb the flow of water and keep water from deteriorating the edges 8.

The semiconductive layer 30 converts one form of energy to an electrical charge or current. The semiconductive layer 30 may (for example) be wafers of semiconductive material aligned in a row, may (for example) be tape or other such adhesive, or may (for example) be in the form of paint and applied to the base layer 32. The semiconductive layer 30 runs lengthwise with the shingle 22 to create a series pathway A (
The semiconductive layer 30 may be a thermoelectric generator in some embodiments, wherein heat is transformed to electrical voltage or energy. This is able to convert not the photons of the sun, but of the heat produced by the sun on the roof 2. Such semiconductive material may be bismuth telluride (Bi2Te3), lead telluride (PbTe), silicon germanium (SiGe), Silicon Phosphorus Boron (SiPB), and the like. These materials must have both high electrical conductivity (σ) and low thermal conductivity (κ) to be good thermoelectric materials. The thermal conductivity of semiconductors can be lowered without affecting their high electrical properties using nanoparticles and nanoparticles impurities (doping). This can be achieved by creating nanoscale features such as particles, wires, or interfaces in bulk semiconductor materials.
It is foreseen that an additional convection layer may be provided under the shingle tiles 22 or as an additional layer to the individual shingle 22 itself to aid in the heat transfer of the semiconductive layer 30 or in the heat differentiation in the semiconductive layer 30. The convection layer may be made from material having molecules randomly moving through Brownian motion or diffusion or large scale motion of molecules or advection or some material or materials having a combination of the two modes. The convection layer also adds an insulative layer to the roof and can assist in air control in the dwelling 1.
In other embodiments, the semiconductive layer 30 may be vibrational generators, wherein a semiconducting crystal is put under strain by kinetic energy, i.e. sound or force, and the vibration creates a small amount of current due to the piezoelectric effect. Such a layer 30 may be more advantageous to populations where the weather is more tropical, though it may also work sufficiently in other environments. The layer 30 may utilize the vibrations from rain drops, hail, snow, sleet, pressure involved from high winds, and the sound of thunder to create energy. It is foreseen that the semiconductive layer 30 may be several strips of different material, wherein each performs a specific task, i.e. one material converts heat to energy, another sound to energy, and so forth. It is also foreseen that the same semiconductive material may perform all the functions of the transducers mentioned and those later developed.
In some embodiments of a vibrational generator, the semiconductor layer 30 may be an adhesive comprising a plurality of three-dimensional (3D) nanostructures. The 3D nanostructure may, for example, include a core and a plurality of spokes extending radially outwardly from the core. The spokes may extend outwardly at a variety of angles. The nanostructure may be formed of one or more materials which give the nanostructure semiconductive characteristics that create charge and/or voltage. During a thunderstorm, the roof 2 may experience hail, which exerts an applied energy on the shingles which, due to the enhanced adhesive having the piezoelectric effect, when the shingles receive an applied energy from the hail, energy is at least partially transferred to the 3D nanostructures such that the nanostructures flex or compress. Here, because the energy may be greater, the nanostructures may experience a greater amount of compression. The nanostructures then return to their natural state due to the elasticity of the nano structures, which returns as an applied energy to the semiconductor layer 30.
The semiconductive layer 30 may be applied or constructed such that a diode is created, directing the current produced to flow in one direction. The diodes could change the direction of the current, therein creating an alternating current situation, which would allow the current to travel further across larger roofs 2.
The semiconductive layer 30 may be constructed as a data collection flow, in which data such as shingle humidity, total energy harvest of all shingle, individual shingle harvest, type of energy converted (i.e. rain vibration versus heat), which side of the roof harvests more energy, individual shingle temperature, etc. can be collected and saved at the energy collector. Such data can then be converted into reports that can be viewed on a display, such as a computer, cellular phone, tablet, and the like. Such reporting can be used to determine the life of individual shingles 22, i.e. if there is rot or water retention in the shingles 22.
The base layer 32 and semiconductive layer 30 are then coated with asphalt or other cement/stone mixture creating the asphalt layer 34 on all sides. The asphalt layer 34 contains mineral fillers that make the shingle 22 waterproof and resist fire better. An additional layer 33, such as a microweave layer or additive known as styrene-butadiene-styrene (SBS), sometimes called modified or rubberized asphalt, is sometimes added to the asphalt mixture to make shingles more resistant to thermal or physical cracking, as well as more resistant to damage from hail impacts, and may also be present. It is foreseen that the semiconductor layer 30 may have a protective layer applied atop, such that when the asphalt layer is applied, it does not affect the mechanics of the semiconductive layer 30.
The surface granule layer 36 covers the asphalt layer 34 on the front surface 23 of the shingle 22. The surface granule layer 36 may be slate, schist, quartz, vitrified brick, stone, ceramic granules, and the like. The back side may also be treated with sand, talc, or mica, for example, to prevent the shingles 22 from sticking to each other before use. Some manufacturers use a fabric backing known as a “scrim” on the back side of shingles 22 to make them more impact resistant, and this may be used in embodiments of the current invention as well.
The sealant layer 38 is applied to the front surface 23 and sometimes to the back surface. The sealant layer 38 may be an adhesive that seals the shingles 22 to one another such that the shingles better resist being blown off by wind or other means. It is foreseen that the semiconductive layer 30 and the sealant layer 38 may be a unitary layer or applied one atop the other to create a conductive path A (

The conductive drip edge 26 may be along both sides 95 of the roof 2, along one side 95 of the roof 2, or along both sides 95 and the bottom of the roof 93. In a first configuration (or “parallel configuration”), two drip edges 26 are positioned with one on each side 95, creating second and third conductive pathways B. Here, the energy flows equally in both directions. This configuration allows for energy collection to occur on both sides of the house 1 as will be further discussed below.
In a second configuration (or “series configuration”), a single drip edge 26 is positioned on one side 95 (
In a third configuration (or “series parallel configuration”), both sides 95 have conductive pathways B, C, and the bottom edge 93 of the roof 2 also has a conductive pathway D (
As depicted in the drawings, a lower electrode 100, such as insulated wire, is connected to the terminal of a collection mechanism 28, such as a battery. The collection mechanism 28 may also be connected to an upper electrode 102 by means of a second electrical connection, such as insulated wire. It is understood that the collection mechanism 28 of the system 20 may, in the alternative, comprise a conventional electrical inverter system or a mechanism for transferring the generated electricity back to the electrical grid.

The shingle clip 24 may be installed within an aperture 25 of the shingle 22 or may be installed over the semiconductive pathway A if the semiconductive pathway is situated on at least one of a top and bottom surface 23, 24 of the shingle 22.
In step 209, a second shingle 22 having a semiconductive pathway A is installed on at least one of the undercourse layer 10 and underlayment layer 9. The second shingle 22 engages the drip edge 26.
In step 211, at least one electrical lead is connected to the drip edge 26 at one end and to an energy collector at the second end.
In step 213, the semiconductive transducer layer transforms energy that is then stored or harvested in the energy collector.
