[0046] The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. Specific examples of components and arrangements are described below to simplify the present disclosure. These are, of course, merely examples and are not intended to be limiting. For example, the formation of a first feature over or on a second feature in the description that follows may include embodiments in which the first and second features are formed in direct contact and may also include embodiments in which additional features may be formed between the first and second features, such that the first and second features may not be in direct contact. In addition, the present disclosure may repeat reference numerals and / or letters in the various examples. ThisDocket No. Y2097-00099repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and / or configurations discussed.

[0047] Further, spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like, may be used herein for ease of description to describe one element or feature’s relationship to another element(s) or feature(s) as illustrated in the figures. The spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. The apparatus may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein may likewise be interpreted accordingly.

[0048] In the present disclosure the singular forms “a,” “an,” and “the” include the plural reference, and reference to a particular numerical value includes at least that particular value, unless the context clearly indicates otherwise. Thus, for example, a reference to “an interlocking structure” is a reference to one or more of such structures and equivalents thereof known to those skilled in the art, and so forth. When values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. As used herein, “about X” (where X is a numerical value) preferably refers to ±10 % of the recited value, inclusive. For example, the phrase “about 8” preferably refers to a value of 7.2 to 8.8, inclusive; as another example, the phrase “about 8%” preferably (but not always) refers to a value of 7.2% to 8.8%, inclusive. Where present, all ranges are inclusive and combinable. For example, when a range of “1 to 5” is recited, the recited range should be construed as including ranges “1 to 4”, “1 to 3”, “1-2”, “1-2 & 4-5”, “1-3 & 5”, “2-5”, and the like. In addition, when a list of alternatives is positively provided, such listing can be interpreted to mean that any of the alternatives may be excluded, e.g., by a negative limitation in the claims. For example, when a range of “1 to 5” is recited, the recited range may be construed as including situations whereby any of 1, 2, 3, 4, or 5 are negatively excluded; thus, a recitation of “1 to 5” may be construed as “1 and 3-5, but not 2”, or simply “wherein 2 is not included.” It is intended that any component, element, attribute, or step that is positively recited herein may be explicitly excluded in the claims, whether such components, elements, attributes, or steps are listed as alternatives or whether they are recited in isolation.

The void is also referred as a “channel.”Docket No. Y2097-00099

[0079] The solar panel 40 is seamlessly integrated into the channel at the top of the door, within the IGU. This design allows the solar panel to charge during the day, storing energy in a high-capacity battery embedded in the system. The system uses advanced Maximum Power Point Tracking (MPPT) technology to ensure efficient energy conversion even in low light or vertical installations.

[0080] A Maximum Power Point Tracking (MPPT) charge controller optimizes solar power systems by electronically tracking the highest power output of panels. The technology of “Maximum Power Point Tracking” is used in solar electric charge controllers. A maximum power point tracker is an electronic DC to DC converter that optimizes the match between the solar array (PV panels) and the battery. It converts a higher voltage DC output from solar panels down to the lower voltage needed to charge batteries. A MPPT charge controllers increase solar system efficiency by electronically tracking and adjusting the electrical operating point of solar panel(s) to ensure they operate at their maximum power output. These devices convert higher voltage, lower current power from panels into lower voltage, higher current power to optimize battery charging.

[0081] In some embodiments, the door 100 may have two pieces of solar panel 40, one of which faces outside of the door or house (or other building), and one of which faces interior of a house and is configured to absorb light from interior.
