Embodiments of the present invention are directed to systems and methods for incorporating solar cells into skylights. These solar cells may be configured to gather sunlight to generate electricity that is used to power any number of components. As just one example, the electricity may be used to power a light source that is integrated into and/or otherwise electrically coupled with the skylight. In such a manner, a skylight may provide light to an interior of a structure during the day, but also at night when there is insufficient ambient light available to light the structure. In some embodiments, the power generated by the solar cells may be used to feed an outlet, trickle charger, and/or other equipment. This allows a structure, such as a shed, garage, cabin, or RV which is not wired to the electrical grid to still receive power to power equipment attached thereto or stored therein.
The subject matter of embodiments of the present invention is described here with specificity to meet statutory requirements, but this description is not necessarily intended to limit the scope of the claims. The claimed subject matter may be embodied in other ways, may include different elements or steps, and may be used in conjunction with other existing or future technologies. This description should not be interpreted as implying any particular order or arrangement among or between various steps or elements except when the order of individual steps or arrangement of elements is explicitly described.
Embodiments of the present invention are directed to skylights that include integrated solar cells. These solar cells are usable to generate electricity that may be used to power one or more peripheral devices, such as lights, power outlets, batteries, trickle chargers, skylight motors, etc. The embodiments described herein integrate the solar panel and/or any wiring into the design of the skylight, eliminating the need to form holes within the roof of a structure on which the skylight is mounted. Additionally, in embodiments in which the skylight includes both a light source and an integrated solar panel, the skylights can provide light to an interior of a structure both during daylight (via the skylight) and darkness (via the solar-powered light source). Such skylights are particularly useful in structures that are not attached to an electrical grid such as storage sheds, recreational vehicles (RVs), cabins, garages, and the like. However, it will be appreciated that the skylights described herein may be utilized with any structure including houses, mobile homes, commercial buildings, etc.
In one embodiment, as shown in
Horizontal flashing 120 may be integral with, and extend away from, a bottom of each exterior side of vertical curb 115. By “integral with,” a person of skill in the art should understand that the two components are of homogenous continuous construction, and form a single physical element. As shown in cross sections A-A and B-B, this also means that there is no interface between such components (horizontal flashing 120 and vertical curb 115). Having no interface between the two components (horizontal flashing 120 and vertical curb 115) at this location provides the advantage of removing an additional location that water may penetrate, that is perhaps present in prior art skylight frames. In some embodiments, horizontal flashing 120 may extend substantially orthogonally away from the bottom of each exterior side 116 of vertical curb 115. By “substantially orthogonal,” a person of skill in the art should understand that an angle of 90 degrees, plus or minus two degrees, is intended.
First vertical member 125A may extend upward from horizontal flashing 120 which extends from a first exterior side 116A of vertical curb 115. In some embodiments, first vertical member 125A may be integral with horizontal flashing 120. First horizontal member 130A may extend from first vertical member 125A, and away from vertical curb 115. Likewise, on a second exterior side 116B, opposite first exterior side 116A, second vertical member 125B may extend upward from horizontal flashing 120 which extends from second exterior side 116B of vertical curb 115. In some embodiments, second vertical member 125B may be integral with horizontal flashing 120. Also similarly, second horizontal member 130B may extend from second vertical member 125B, and away from vertical curb 115. In some embodiments, first horizontal member 130A may be integral with first vertical member 125A, and second horizontal member 130B may be integral with second vertical member 125B.
In some embodiments, a bottom side of each horizontal member 130 may include a roughened, textured, or the like surface 131. Likewise, a portion of an outer side of each vertical member 125 may also include a roughened, textured, or the like surface 126. In some embodiments, as shown in
In some embodiments, first vertical nub 135A may extend downward from first horizontal member 130A at an opposite end of first horizontal member 130A from first vertical member 125A. Likewise, second vertical nub 135B may extend downward from second horizontal member 130B at an opposite end of second horizontal member 130B from second vertical member 125B. In some embodiments, first vertical nub 135A may be integral with first horizontal member 130A, and second vertical nub 135B may be integral with second horizontal member 130B. As shown in
Thus, as demonstrated in
In some embodiments, vertical members 125 may be substantially parallel with proximate/nearby exterior sides 116 of vertical curb 115. By “substantially parallel,” a person of skill in the art should understand that parallel, plus or minus two degrees thereof, is intended. In some embodiments, horizontal flashing 120 may be substantially parallel with horizontal members 130. In some embodiments, vertical members 125 and exterior sides 116 of vertical curb 115 may be substantially orthogonal to horizontal flashing 120 and horizontal members 130.
In some embodiments, horizontal flashing 120 which extends from a third exterior side 116C of vertical curb 115 has no substantial features thereon. Third exterior side 116C of vertical curb 115 couples first exterior side 116A with second exterior side 116B. Likewise, in some embodiments, horizontal flashing 120 which extends from a fourth exterior side 116D of vertical curb 115 has no substantial features thereon. Fourth exterior side 116D of vertical curb 115 also couples first exterior side 116A with second exterior side 116B, but at the other end thereof.
In some embodiments, powered lights may be present on the interior of vertical curb 115 or some other interior portion of skylight 100. The lights may be powered by batteries, solar power, or hardwired external sources such as power from the associated structure.
Prior to disposing frame 110 of skylight 100 in this particular orientation on the roof, shingles 410 were disposed on the roof in the location that is underneath horizontal flashing 120 which extends from fourth exterior side 116D of vertical curb 115.
After disposing frame 110 of skylight 100 in the particular orientation on the roof, shingles 410 were disposed on the roof such that shingles 410 at least partially cover horizontal flashing 120 which extends from first exterior side 116A of vertical curb 115, and also such that shingles 410 abut first vertical member 125A underneath first horizontal member 130A. A sealant, mastic for example, may be disposed within horizontally-open channel 145 between shingles 410 and first horizontal member 130A, and grip to the surfaces of horizontally-open channel 145, including roughened, textured, or the like surfaces 126, 131 within said channel. In some embodiments, horizontal member 130 may be forced downward such that first nub 135A grips into shingles 410. Construction about the other side of skylight may be substantially similar, as shown in
Finally, to complete installation, after disposing frame 110 of skylight 100 in the particular orientation on the roof, shingles 410 may be disposed on the roof such that shingles 410 at least partially cover horizontal flashing 120 which extends from the third exterior side 116C of vertical curb 115.
As can now be seen, water flowing around skylight 100 from precipitation, etc. will proceed to flow around skylight 100, and flow down vertically-open channels 140, between vertical curb 115 and vertical members 125, avoiding the interface of shingles 410 to frame 110 which is located on the other side of vertical members 125. This contrasts to many prior art skylights where shingles may abut the vertical curb thereof directly, providing an interface between the shingles and the vertical curb for water to pass through damaging the roof and structure underneath.
At block 540, shingles and other roofing materials are disposed on the sides of frame 110 such that they abut the outer face of vertical members 125. At block 550, shingles and other roofing materials are disposed over at least a portion of horizontal flashing 120 which extends from the top side of frame 110.
At block 560, a sealant is disposed in the space defined between shingles 410, vertical member 125, and horizontal members 130. Sealant may also be disposed at other locations where frame 110 interfaces with shingles 410. In some embodiments, at block 570, horizontal members 130 may be forced downward, potentially moving nubs 135 into shingles 410 and/or other roofing materials.
In some embodiments, each side (or each side that is to be inclined with a slope of a roof structure) of the frame 604 may include a vertical curb 608 and/or vertical member 610 that define a vertically-open channel 612 having an open top and a homogenous uninterrupted inner surface that provides a drainage path for water, without allowing any of the water to get underneath the skylight 600 and/or any roofing shingles positioned adjacent the skylight 600.
As shown here, the solar power unit 602 is mounted to an interior of the frame 604 and positioned underneath the skylight panel 606. Such a configuration places the solar power unit 602 in direct sunlight (with only the skylight panel 606 serving as an intervening component) while protecting the solar power unit 602 from the elements, such as hail, dust, dirt, etc. The solar power unit 602 may be mounted to the frame 604 using a bracket 614 and/or other mounting device. In some embodiments, the bracket 614 may be mounted permanently to the frame 604, such as by welding, fastening, and/or other securement techniques. In other embodiments, the bracket 614 may be removable from the frame 604. For example, the bracket 614 may be secured using a snap fit feature, magnets, and/or other removable fastening mechanism. In one particular embodiment, such as illustrated in
In some embodiments, the solar power unit 602 may be coupled with a light source 618, such as a light source including one or more light emitting diodes (LEDs), although other light sources may be used in some embodiments. As illustrated here, the solar panel 602 and the light source 618 may be integrated into a single unit, with the light source 618 being positioned on an underside of the solar power unit 602. Such an arrangement allows the light source 618 to be powered directly by the solar power unit 602, which may include a battery that allows the solar power unit 602 to store electricity for later use by the light source 618. For example, the battery enables the light source 618 to be activated at night and/or during other periods in which no sunlight is present. In some embodiments, the light source 618 may be always on, may be motion-activated, light activated, and/or controlled by a switch. While illustrated here with a single rectangular solar power unit 602 and light source 618 positioned in a center of the frame 604, it will be appreciated that any number of solar power units 602 and/or light sources 618 of any shape may be positioned within an interior of the skylight 600 in any position and/or orientation.
For example,
As illustrated in
The power that is generated using the solar power unit 1002 may be used to power any number of devices. For example, the power may be used to power one or more interior lights 1018 that are installed within the structure 1006. These lights 1018 may be configured to be always on, motion activated, operated by a switch 1020, light activated, and/or otherwise controlled. The power from the solar power unit 1002 may also be used to power one or more outlets 1022 and/or trickle chargers that may be used to supply power and/or recharge other devices. In some embodiments, a power storage unit, such as a dedicated battery 1024 may be included to store excess power for later use. In some embodiments, such as shown in
In some embodiments, all or a substantial portion of a skylight opening may be utilized for a solar power unit in order to capture more solar power, enabling a solar power unit to power larger and/or more devices.
In some embodiments, a skylight 1300 may include a solar power unit 1302 that forms a frame around a portion of an interior portion of the skylight 1300 as illustrated in
In some embodiments, the skylights designs described herein may be utilized in conjunction with semi and/or fully transparent solar cells. In such embodiments, the solar cells may be mounted to cover some or all of the central opening of the skylights, thereby allowing light in while the solar cells generate energy. In some embodiments, any circuitry and/or components of a solar power unit that are opaque may be positioned close to and/or integrated into the frame of the skylight.
