    DETAILED DESCRIPTION OF THE INVENTION

    [0127] The following detailed description should be read with reference to the drawings. The drawings, which are not to scale, depict illustrative embodiments and are not intended to limit the scope of the invention.

    [0128] Referring to FIGS. 1 to 9, in accordance with one embodiment of the invention, a mobile solar tree 100 comprises a solar tree base 102 and a solar tree trunk 104 extending from the solar tree base 102. In one embodiment, the solar tree trunk 104 may extend substantially perpendicularly from the solar tree base 102. One or more solar tree branches 106 are connected to the solar tree trunk 104. Preferably, the solar tree branches 106 are hingedly or pivotably connected to the solar tree trunk 104 such that they may be actuated with respect to the solar tree trunk 104. In the embodiment shown in FIGS. 1 to 3, the solar tree trunk 104 comprises one or more horizontal bars 105 for attachment of the solar tree branches 106. For example, the solar tree branches 106 may be actuated mechanically, hydraulically, or electrically. In addition, the actuation may be manual or automatic. In one embodiment, the solar tree branches 106 may be actuated in a similar manner to that of the opening and closing of awnings.

    [0129] The mobile solar tree 100 may be removably fixed in place, with the advantage of being easily demounted and moved to other locations as necessary.

    [0130] One or more of the solar tree base 102, the solar tree trunk 104, or the solar tree branches 106 may be connected to a security system 108 to deter theft or vandalism or for other purposes. The security system 108 may be part of the mobile solar tree 100 or it may be separate from it. Moreover, the mobile solar tree 100 may house or be attached to a charging system 110. The charging system 110 may be used to provide electrical power that is generated by the mobile solar tree 100 to charge a battery or to charge an electric vehicle or any other item.

    [0131] The solar tree base 102 may be shaped in any number of forms but preferably is shaped like the base of a conventional tree. For example, in the embodiment shown in FIGS. 1 to 3, the solar tree base 102 has a substantially elongated shape. It may be formed from lightweight or composite plastic or metal. Preferably, the solar tree base 102 is substantially hollow, allowing it to be filled with a suitable ballast (such as water) that may be drained out when required to dismantle the mobile solar tree 100 for deployment to another location.

    [0132] It may also be possible to fit the bottom of the solar tree base 102 with one or more mobility accessories 112 for allowing the mobile solar tree 100 to be more easily moved or transported from one location to another. The mobility accessories 112 may include wheels, casters, or the like. For example, in the embodiment shown in FIGS. 1 to 3, the solar tree base 102 is fitted with pairs of wheels as the mobility accessories 112. The mobility accessories 112 may be motorized. In addition, they may also be configured to be recessed or hidden within the solar tree base 102 when not in use for ease of transport or for aesthetic purposes. This may be especially the case where the mobile solar tree 100 is expected to be moved over short distances, as this avoids the need to have to close or dismantle the mobile solar tree 100 each time. Furthermore, the solar tree base 102 may also incorporate seating, especially when deployed in public parks and places.

    [0133] The mobile solar tree 100 further comprises one or more photovoltaic (PV) panels 114 that are attached to the solar tree branches 106. The PV panels 114 are able to convert solar energy into electricity. The PV panels 114 comprise one or more sheets 116 of photovoltaic material and one or more anchors 118. The sheets 116 may be stretched, with the sheets 116 connected to the anchors 118, preferably proximate to the edges of the sheets 116. The anchors 118 are configured to be attached to the solar tree branches 106. In one embodiment, the PV panels 114 may be arranged to form one or more layers 120 of horizontally- or vertically-extended PV panels 114 to simulate the fronds or branches of a tree. For example, in the embodiment shown in FIG. 3, there are two layers 120 of PV panels 114 (one above another).

    [0134] Preferably, the PV panels 114 are arranged in such a fashion so as to avoid them overlapping with each other as much as possible to allow the solar rays and light to filter through each layer 120 while trying to avoid casting shade on each other as much as possible, in order to maximize the efficiency of the PV panels 114 (see, for example, FIGS. 4 and 5). In one embodiment, the sheets 116 of photovoltaic material are substantially transparent. In this embodiment, the PV panels 114 may be arranged in an overlapping manner since the overlapping does not affect the penetration of the solar rays and efficiency of the PV panels 114.

    [0135] In another embodiment, the PV panels 114 may be inserted or sandwiched within or sandwiched between layers of a material or fabric, with the upper layer of the material or fabric being substantially transparent to allow sunlight through. This embodiment would also help in replacing the PV panels 114 whenever they need to be replaced due to damage or failure. Each of the sandwiched PV panels 114 could constitute a mobile solar cloud and they may be interconnected in a variety of methods, as described later. Those units could also be manufactured to be sold as individual PV panels kits ready to be connected together as desired.

    [0136] The mechanisms for opening, deploying, extending, or closing the PV panels 114 are preferably housed in one or both of the solar tree trunk 104 or the solar tree branches 106. These may be mechanically or hydraulically operated, or electrically motorized and controlled by an electronic system and program, which may be reprogrammed and updated as required, with various degrees of automation. For example, the mobile solar tree 100 may be connected (wiredly or wirelessly) to a weather system 122 whereby the mobile solar tree 100 would be caused to close if the weather becomes (or is forecast to be) inclement. The mobile solar tree 100 may also be linked (wiredly or wirelessly) with one or more other mobile solar trees 100 so that all of them open and close when required, such as in emergencies or when multiple mobile solar trees 100 are being deployed in a park, an area, a building, or any other structure. The mobile solar trees 100 arranged in this manner may be used to form an actual solar “park” without having to remove plants or dig up the grounds.

    [0137] The solar tree trunk 104 may be substantially hollow to allow it to house the solar tree branches 106 within it. The solar tree trunk 104 comprises an outer wall 124 that may be telescoping, such that the overall height of the solar tree trunk 104 may be greatly reduced when the outer wall 124 is collapsed together. Preferably, the outer wall 124 is constructed from a strong lightweight plastic, metal, or composite material. Referring to FIGS. 6 and 7, the solar tree trunk 104 may have an extended (or open) configuration 126 and a retracted (or closed) configuration 128. Because of the telescoping nature of the outer wall 124, portions of the solar tree trunk 104 may extend from inside one another during the transition from the retracted configuration 128 to the extended configuration 126. For example, referring to FIGS. 8 and 9, the outer wall 124 may be broken up into a plurality of wall segments 130a, 130b, 130c, wherein a higher wall segment 130a may telescope into lower wall segment 130b, 130c when transitioning from the extended configuration 126 to the retracted configuration 128. Preferably, there is a mechanism to lock the wall segments 130 in place when the wall segments 130 are fully extended from each other and a mechanism to unlock the wall segments 130 in order to begin the process of collapsing the wall segments 130. The number and size of the wall segments 130a, 130b, 130c would depend on the overall size and height required of the mobile solar tree 100.

    [0138] Alternatively, in another embodiment, instead of the wall segments 130 telescoping into one another, the wall segments 130 may be removably detached from each other. The wall segments 130 may still be of different sizes.

    [0139] The solar tree branches 106 are preferably attached to the PV panels 114 in such a manner as to allow for the manipulation and movement of the PV panels 114. The solar tree branches 106 may be mechanically operated or electrically motorized and controlled as described above.

    [0140] In another embodiment, the mobile solar tree 100 may also comprise one or more deployment cables 132 connected to the solar tree trunk 104 and to solar tree branches 106. The deployment cables 132 may be used to assist in deploying the solar tree branches 106. For example, the deployment cables 132 may extend or retract from the solar tree trunk 104, thereby causing the solar tree branches 106 to pivot away from or pivot toward, respectively, the solar tree trunk 104.

    [0141] The solar tree branches 106 may be configured to deploy the PV panels 114 to open horizontally or vertically (and various degrees in between), and the solar tree branches 106 may open in layers 120, spaced as necessary to allow for the sun to reach the PV panels 114. There are many possible mechanisms for opening and closing the PV panels 114. There are also many shapes and designs possible for the solar tree branches 106 and the PV panels 114. For example, preferably, the PV panels 114 situated lower on the solar tree trunk 104 extend further away from the solar tree trunk 104 to avoid being shadowed by the PV panels 114 located above them. In the case where the sheets 116 of the PV panels 114 are substantially transparent or translucent, this is generally less important as the light is able to filter down through the sheets 116 without affecting the performance of the PV panels 114 underneath, and more layers 120 of PV panels 114 may be used in a denser configuration. It is also possible to use a combination of transparent and less transparent PV panels 114 when and as required to provide better performance.

    [0142] The height of the mobile solar tree 100 may be increased or decreased as required and the design could vary upon the taste. The size and number of the solar tree branches 106 would generally be the main factor in deciding the amount of energy produced.

    [0143] Depending on the overall height of the mobile solar tree 100, the solar tree trunk 104 may also comprise a central reinforcement rod 134 to provide additional strength and support. The reinforcement rod 134 may also be telescoping to reduce its overall height when transitioning from the extended configuration 126 to the retracted configuration 128.

    [0144] By way of example only, using the CIGS—(Cadmium Indium Gallium Selenium) type of thin and light and flexible photovoltaic cells for the sheets 116, a mobile solar tree 100 that is approximately three meters high may have three layers 120 of PV panels 114, with a one-meter spacing between each layer 120 to allow as much light to pass through to the PV panels 114. Each layer 120 may have eight solar tree branches 106, if, for example, the solar tree trunk 104 has a generally octagonal cross-section as shown in FIG. 4 (or even a round cross-section with octagonal spacing). The solar tree branches 106 may vary in width and length, and in order to allow more light to reach the PV panels 114 of the solar tree branches 106 below, the PV panels 114 may be staggered so that there is a space and gap from one layer 120 over the other. Therefore, one possible configuration could be as follows:

    [0145] The PV panels 114 in the upper layer 120 may be 0.5 meters wide by 1.5 meters long, thus creating a surface area of 0.75 square meters, with eight PV panels 114 totaling 6 square meters.

    [0146] The PV panels 114 in the middle layer 120 may be 0.75 meters wide by 2 meters long, thus creating a surface area of 1.5 square meters, with eight PV panels 114 totaling 12 square meters.

    [0147] The PV panels 114 in the lower layer 120 may be 1 meter wide by 2 meters long, thus creating a surface area of 2 square meters, with eight PV panels 114 totaling 16 square meters.

    [0148] The total surface area of the PV panels 114 for the three layers 120 would be 34 square meters. At an average, PV panels 114 comprising flexible sheets 116 of photovoltaic material may typically produce 120 watt/square meter. Therefore, the mobile solar tree 100 would produce approximately 120 watt/m.sup.2×34 m.sup.2=4,080 watts, which could power an average three-bedroom house with possibly a window air conditioner or even more, depending on the geographic location and if the sun shines all the time. The output would be even higher when using mono- or poly-silicon fiberglass-based thin and light and flexible panels.

    [0149] Such a mobile solar tree 100 would have 34 square meters area of PV panels 114 while it would occupy a footprint of only 16 square meters (4 meters×4 meters) in plan and would use only 4 square meters of floor area with a base of 2 meters×2 meters. This could constitute a saving of over 82.3% of land in comparison to the traditional ground-mounted PV panel systems, which would occupy more than 16 square meters, with a PV area of only 16 square meters to allow for distances between panels.

    [0150] It is important to point out that mobile solar trees 100 with organic photovoltaic (OPV) and other transparent PV material could be able to produce higher yields due to the ability of stacking more PV panels 114 in multiple layers.

    [0151] Referring to FIGS. 10 to 18, in another embodiment of the invention, a mobile solar vessel 200 comprises a solar vessel base 202 and a solar vessel mast 204 extending from the solar vessel base 202. In one embodiment, the solar vessel mast 204 may extend substantially perpendicularly from the mobile solar vessel 200. One or more solar vessel sails 206 are connected to the solar vessel mast 204. Preferably, the solar vessel sails 206 are hingedly or pivotably connected to the solar vessel mast 204 such that they may be actuated with respect to the solar vessel mast 204. For example, the solar vessel sails 206 may be actuated mechanically, hydraulically, or electrically. In addition, the actuation may be manual or automatic. In one embodiment, the solar vessel sails 206 may be actuated in a similar manner to that of the opening and closing of awnings.

    [0152] The mobile solar vessel 200 may be removably fixed in place, with the advantage of being easily demounted and moved to other locations as necessary.

    [0153] One or more of the solar vessel base 202, the solar vessel mast 204, or the solar vessel sails 206 may be connected to security system 108 to deter theft or vandalism or for other purposes. The security system 108 may be part of the mobile solar vessel 200 or it may be separate from it. Moreover, the mobile solar vessel 200 may house or be attached to charging system 110. The charging system 110 may be used to provide electrical power that is generated by the mobile solar vessel 200 to charge a battery or to charge an electric vehicle or any other item.

    [0154] The solar vessel base 202 may be shaped in any number of forms but preferably is shaped like the base of a conventional boat hull. For example, in the embodiment shown in FIGS. 10 to 12, the solar vessel base 202 has a substantially elongated shape. It may be formed from lightweight or composite plastic or metal. Preferably, the solar vessel base 202 is substantially hollow, allowing it to be filled with a suitable ballast (such as water) that may be drained out when required to dismantle the mobile solar vessel 200 for deployment to another location.

    [0155] It may also be possible to fit the bottom of the solar vessel base 202 with one or more vessel mobility accessories 212 for allowing the mobile solar vessel 200 to be more easily moved or transported from one location to another. The vessel mobility accessories 212 may include wheels, casters, or the like. For example, in the embodiment shown in FIGS. 10 to 12, the solar vessel base 202 is fitted with pairs of wheels as the vessel mobility accessories 212. The vessel mobility accessories 212 may be motorized. In addition, they may also be configured to be recessed or hidden within the solar vessel base 202 when not in use for ease of transport or for aesthetic purposes. This may be especially the case where the mobile solar vessel 200 is expected to be moved over short distances, as this avoids the need to have to close or dismantle the mobile solar vessel 200 each time. Furthermore, the solar vessel base 202 may also incorporate seating, especially when deployed in public parks and places.

    [0156] The mobile solar vessel 200 further comprises one or more PV panels 114 that are attached to the solar vessel sails 206. The anchors 118 on the PV panels 114 are configured to be attached to the solar vessel sails 206. In one embodiment, the PV panels 114 may be arranged to form one or more layers 120 of horizontally- or vertically-extended PV panels 114 to simulate the sails of a boat (not shown).

    [0157] Preferably, as with the mobile solar tree 100, the PV panels 114 for the mobile solar vessel 200 are arranged in such a fashion so as to avoid them overlapping with each other as much as possible to allow the solar rays and light to filter through while trying to avoid casting shade on each other as much as possible, in order to maximize the efficiency of the PV panels 114. In one embodiment, the sheets 116 of photovoltaic material are substantially transparent. In this embodiment, the PV panels 114 may be arranged in an overlapping manner since the overlapping does not affect the penetration of the solar rays and efficiency of the PV panels 114.

    [0158] The mechanisms for opening, deploying, extending, or closing the PV panels 114 are preferably housed in one or both of the solar vessel mast 204 or the solar vessel sails 206. These may be mechanically or hydraulically operated, or electrically motorized and controlled by an electronic system and program, which may be reprogrammed and updated as required, with various degrees of automation. For example, the mobile solar vessel 200 may be connected (wiredly or wirelessly) to weather system 122 whereby the mobile solar vessel 200 would be caused to close if the weather becomes (or is forecast to be) inclement. The mobile solar vessel 200 may also be linked (wiredly or wirelessly) with one or more other mobile solar vessels 200 or one or more mobile solar trees 100 so that all of them open and close when required, such as in emergencies or when multiple mobile solar vessels 200 and/or mobile solar trees 100 are being deployed in a park, an area, a building, or any other structure. The mobile solar vessels 200 and mobile solar trees 100 arranged in this manner may be used to form a virtual solar “park” without having to remove plants or dig up the grounds.

    [0159] The solar vessel mast 204 may be substantially hollow to allow it to house the solar vessel sails 206 within it. The solar vessel mast 204 comprises a vessel outer wall 224 that may be telescoping, such that the overall height of the solar vessel mast 204 may be greatly reduced when the vessel outer wall 224 is collapsed together. Preferably, the vessel outer wall 224 is constructed from a strong lightweight plastic, metal, or composite material. Referring to FIGS. 15 to 17, the solar vessel mast 204 may have an extended (or open) vessel configuration 226 and a retracted (or closed) vessel configuration 228. Because of the telescoping nature of the vessel outer wall 224, portions of the solar vessel mast 204 may extend from inside one another during the transition from the retracted vessel configuration 228 to the extended vessel configuration 226. For example, the vessel outer wall 224 may be broken up into a plurality of vessel wall segments 230, wherein a higher vessel wall segment 230 may telescope into a lower vessel wall segment 230 when transitioning from the extended vessel configuration 226 to the retracted vessel configuration 228. For example, referring to FIGS. 17 and 18, the outer wall 224 may be broken up into a plurality of wall segments 230a, 230b, 230c, wherein a higher wall segment 230a may telescope into lower wall segment 230b, 230c when transitioning from the extended configuration 226 to the retracted configuration 228. Preferably, there is a mechanism to lock the vessel wall segments 230 in place when the vessel wall segments 230 are fully extended from each other and a mechanism to unlock the vessel wall segments 230 in order to begin the process of collapsing the vessel wall segments 230. The number and size of the vessel wall segments 230 would depend on the overall size and height required of the mobile solar vessel 200.

    [0160] Alternatively, in another embodiment, instead of the vessel wall segments 230 telescoping into one another, the vessel wall segments 230 may be removably detached from each other. The vessel wall segments 230 may still be of different sizes.

    [0161] Depending on the overall height of the mobile solar vessel 200, the solar vessel mast 204 may also comprise a central vessel reinforcement rod 234 to provide additional strength and support. The vessel reinforcement rod 234 may also be telescoping to reduce its overall height when transitioning from the extended configuration 226 to the retracted configuration 228.

    [0162] The solar vessel sails 206 are preferably attached to the PV panels 114 in such a manner as to allow for the manipulation and movement of the PV panels 114. The solar vessel sails 206 may be mechanically operated or electrically motorized and controlled as described above.

    [0163] In another embodiment, the mobile solar vessel 200 may also comprise one or more vessel deployment cables 232 connected to the solar vessel mast 204 and to solar vessel sails 206. The vessel deployment cables 232 may be used to assist in deploying the solar vessel sails 206. For example, the vessel deployment cables 232 may extend or retract from the solar vessel mast 204, thereby causing the solar vessel sails 206 to pivot away from or pivot toward, respectively, the solar vessel mast 204.

    [0164] The solar vessel sails 206 may be configured to deploy the PV panels 114 to open horizontally or vertically (and various degrees in between), and the solar vessel sails 206 may open in layers 120, spaced as necessary to allow for the sun to reach the PV panels 114. There are many possible mechanisms for opening and closing the PV panels 114, and some examples are shown in FIG. 18b. There are also many shapes and designs possible for the solar vessel sails 206 and the PV panels 114, as shown in FIG. 18b. For example, preferably, the PV panels 114 situated lower on the solar vessel mast 204 extend further away from the solar vessel mast 204 to avoid being shadowed by the PV panels 114 located above them. In the case where the sheets 116 of the PV panels 114 are substantially transparent or translucent, this is generally less important as the light is able to filter down through the sheets 116 without affecting the performance of the PV panels 114 underneath, and more layers 120 of PV panels 114 may be used in a denser configuration. It is also possible to use a combination of transparent and less transparent PV panels 114 when and as required to provide better performance.

    [0165] The height of the mobile solar vessel 200 may be increased or decreased as required and the design could vary upon the taste. The size and number of the solar vessel sails 206 would generally be the main factor in deciding the amount of energy produced.

    [0166] By way of example only, using the CIGS-type of thin and light and flexible photovoltaic cells for the sheets 116, a mobile solar vessel 200 that is approximately three meters high may have multiple layers 120 of PV panels 114, with a 0.5-meter spacing between each layer 120 to allow as much light to pass through to the PV panels 114. Each layer 120 may have eight solar vessel sails 206, if, for example, the solar vessel mast 204 has a generally octagonal cross-section (or even a round cross-section with octagonal spacing). For example, the PV panels 114 for the mobile solar vessel 200 may be generally triangular in shape.

    [0167] In one configuration, each of the PV panels 114 may have a base length of 3 meters wide by 3 meters high, thus creating a surface area of 4.5 square meters per PV panel 114. With 8 PC panels 114, there would be a total surface area of 36 square meters. However, if the PV panels 114 were spaced closer together, the number of PV panels 114 may be doubled (i.e. to 16), with the total surface area then being 72 square meters.

    [0168] There are other possible embodiments of the mobile solar vessel 200 and how the solar vessel masts 204 fan out. For example, the PV panels 114 may be arranged in an “upside-down” orientation (as shown in FIG. 12), with the wide base being at the top. This would allow the PV panels 114 to fan out more. This would also allow the PV panels 114 to be farther away from one another at the top where the area is larger, and this would enable them to absorb more light, especially during the parts of the day with the highest illumination. This configuration allows for a smaller footprint area on the ground while taking up more space at higher levels.

    [0169] It is also possible to use a combination of different configurations of the PV panels 114 as a head-to-toe design and other designs when required to deploy as much surface area of PV panels 114 as possible.

    [0170] The total surface area of the PV panels 114 attached to the solar vessel sails 206 may be 36 square meters. At an average, PV panels 114 comprising flexible sheets 116 of photovoltaic material may typically produce 120 watt/square meter. Therefore, the mobile solar vessel 200 could generate about 120 watt/m.sup.2×36 m.sup.2=4,320 watts, which could power an average three-bedroom house with possibly a window air conditioner or even more depending on the geographic location and if the sun shines all the time.

    [0171] In the case where the surface area of the PV panels 114 is 72 square meters, the power generated would be approximately 120 watt/m.sup.2×72 m.sup.2=8,640 watts, which could power an even larger (perhaps a six-bedroom) house with possibly a window air conditioner or even more depending on the geographic location and if the sun shines all the time.

    [0172] The solar vessel sails 206 may carry between 36 to 72 square meters of surface area of PV panels 114, while they would occupy a footprint space area of only 36 square meters (6 m×6 m) in plan and would use only 6 square meters of floor area with an assumed base of 2 m×3 m. This constitutes a saving of over 82.3% of land in comparison to the traditional ground-mounted PV panel systems.

    [0173] It is important to point out that mobile solar vessels 200 with OPV and other transparent PV material could be able to produce higher yields due to the ability of stacking more PV panels 114 in multiple layers, and some are able to provide almost similar output per PV panel 114 as the CIGS used for the calculations above and may even eventually exceed it. With new PV materials emerging, even more energy output and options are possible.

    [0174] Referring to FIGS. 19 to 51, in another embodiment of the invention, a dynamic building-integrated photovoltaic (DBIPV) structure 300 incorporates portions of the mobile solar tree 100 and the mobile solar vessel 200. The DBIPV structure 300 is configured to be embedded or attached to a structure 400 (such as a building) and is configured to open and close when desired. The DBIPV structure 300 comprises a plurality of PV panels 114 and may be used where there are space and other limitations. For example, the DBIPV structure 300 may be attached to one or more parts of the structure 400 to provide for the installation of PV panels 114 where it was not possible before or where it is desired to increase the number PV panels 114 to increase the surface area.

    [0175] Preferably, the PV panels 114 used with the DBIPV structure 300 may comprise thin and light and flexible sheets 116 of photovoltaic material (compared to more conventional stiff panels). The sheets 116 may also be translucent and may be shaped in various designs and shapes as desired. As most panels are of a set shape or design, it is possible that the sheets 116 be attached to a background layer which could generally be light and flexible or possibly at times less flexible to assist in the final design and outlook. The different and various designs may also be necessary when the DBIPV structures 300 are used in houses and/or locations where it is necessary to avoid any complaints or objections of the neighbors or the community. Those complaints could be similar to those when a solar farm is being built near a residential neighborhood or on agricultural land.

    [0176] In time, the sheets 116 may be formed by spraying or painting photovoltaic cells on a background substrate.

    [0177] The DBIPV structure 300 further comprises a DBIPV base 302 that houses the necessary mechanisms for operating the DBIPV structure 300. The DBIPV base 302 may be placed within a compartment within structure walls 402 of the structure 400 or in a compartment attached to the structure walls 402 of the structure 400. The DBIPV base 302 may use the same or different extension mechanism for deploying the various parts of the DBIPV structure 300 (compared to the solar tree base 102 and the solar vessel base 202). For example, the DBIPV base 302 may be extended generally horizontally from the structure walls 402 before being deployed vertically. In this manner, it may not be necessary to include a heavy base to anchor the DBIPV base 302 since it would be anchored to the structure walls 402.

    [0178] Referring to FIGS. 20 to 25, the DBIPV structure 300 may take several forms, as shown as 300a to 300u.

    [0179] The DBIPV structure 300 (see, for example, 300d) may further comprise a DBIPV stem 304 attached to the DBIPV base 302. The DBIPV stem 304 is analogous to the solar tree trunk 104 and the solar vessel mast 204. The DBIPV stem 304 may be telescoping (e.g. with the DBIPV stem 304 comprising a plurality of stem segments 330 that collapse within one another) and may have different mechanisms for deployment as it may be extending out of one of the structure walls 402. Alternatively, the stem segments 330 may be removably detached from each other (e.g. instead of being telescoping). The stem segments 330 may be of different sizes.

    [0180] The DBIPV structure 300 further comprises one or more DBIPV fronds 306 attached to the DBIPV stem 304, which are analogous to the solar tree branches 106 and the solar vessel sails 206. Preferably, the DBIPV fronds 306 are hingedly or pivotably connected to the DBIPV stem 304. One or more of the PV panels 114 are attached to the DBIPV fronds 306. There may be differences in how the DBIPV fronds 306 are deployed (compared to the solar tree branches 106 and the solar vessel sails 206) in order to accommodate the deployment out of one of the structure walls 402. For example, it may be easier to deploy (i.e. open and/or close) a rectangular or square PV panel 114 when it is being housed in the structure wall 402 or in the structure 400 and being deployed outwardly (rather than vertically), as it would not necessarily need to be folded in tight conditions or have to be wrapped. Accordingly, the PV panels 114 in this embodiment may be less flexible than those used in the mobile solar tree 100 and the mobile solar vessel 200.

    [0181] Moreover, as the DBIPV stem 304 is generally extended out of the structure wall 402 or the structure 400 itself, the DBIPV stem 304 may also be deployed at an angle so as to fan the DBIPV fronds 306 and allow the use of more DBIPV fronds 306 with perhaps different designs or in groups of smaller DBIPV fronds 306. They may be arranged so as to not be shadowed by one another as much as possible.

    [0182] Referring to FIGS. 26 to 28, various embodiments of the DBIPV structure 300 are shown. These embodiments include floating solar clouds 500, dynamic building-integrated photovoltaics bellows (DBIPVB) 600, and solar tree bellows 700 and lamppost bellows 602. FIG. 26 depicts possible installations for these three embodiments in relation to a structure 400.

    [0183] Both the floating solar clouds 500 and the DBIPVB 600 may be arranged in a horizontal and/or vertical configuration. Referring to FIG. 26, the floating solar cloud 500 may be in a horizontal (500a) or vertical (500b) configuration. Similarly, the DBIPVB 600 may be in a horizontal (600a) or vertical (600b) configuration. Other orientations for the floating solar clouds 500 and the DBIPVB 600 are also possible.

    [0184] Referring to FIG. 29, the floating solar clouds 500 and the DBIPVB 600 comprise PV panels 114. The PV panels 114 may be in a double-sided back-to-back configuration for the vertical configurations (e.g. floating solar cloud 500b and DBIPVB 600b). Such double-sided configurations 500db and 600db of the PV panels 114 are formed by having two PV panels 114 fitted together back-to-back or installed or attached to a base layer 502 between the two PV panels 114. Furthermore, the two PV panels 114 may instead be inserted into a substantially transparent sleeve 504. By arranging the two PV panels 114 back-to-back, they can be used when both the front and back of the floating solar cloud 500 or the DBIPVB 600 are exposed to light. It is also possible to use such back-to-back configurations of the PV panels 114 for horizontal configurations of the floating solar cloud 500 or the DBIPVB 600 (i.e. 500a, 600a, respectively).

    [0185] Referring again to FIG. 29, one or more of the PV panels 114 may be encased within the sleeve 504, which would have openings and pockets/fittings designed to accommodate any fittings or attachments used by the PV panels 114. As the PV panels 114 are typically thin and flexible, they may not always be properly or securely adhered to the base layer 502, resulting in the PV panels 114 peeling off after extended periods of time. This is especially the case where there is constant movement from wind and also when used at high temperatures. Moreover, deploying the PV panels 114 without the additional base layer 502 in those embodiments subject to heavy winds and stresses for extended periods could result in damage of the PV panels 114.

    [0186] The sleeve 504 also helps with the ventilation of the PV panels 114 where some or most may become fairly hot in the process of generating the energy and even more so when used in warm climate locations. Inserting the PV panels 114 inside the sleeve 504 allows for better ventilation and also ensures that they are held in place safely. The sleeve 504 also assists when one of the PV panels 114 needs to be changed or replaced (especially when the PV panel 114 fails or new models are available with higher output or lower cost) or for maintenance. This can be done easily and quickly and without damaging the installations.

    [0187] The sleeve 504 may also make it easier to manufacture a ready-to-use unit for export to anywhere without having to restrict the consumer to a specific panel manufacturer and allows the consumer to make the choice. This will also result in the possibility of buying the required solar installation from the appropriate hardware store to create all the energy required for a unit or a house or structure.

    [0188] The sleeve 504 may generally be formed from a durable substantially clear top layer that allows light to pass through to allow the enclosed PV panels 114 to perform with maximum efficiency. The sleeve 504 may also instead comprise certain types of composite or/and netting fabric, while the base layer 502 may also be formed from a flexible and durable substrate such as those used for vehicle shades. The sleeve 504 may be manufactured individually (as shown in FIG. 29) and then connected together as required. Alternatively, the sleeve 504 may be formed to match the required length of the floating solar cloud 500 or also in long sheets as in FIGS. 30 to 32 for the floating solar cloud 500 and also FIGS. 33 to 51 for the DBIPVB 600 and the floating solar clouds 500.

    [0189] The sleeve 504 may also be formed with a light frame of composite materials for extra strength or simply stitching or welding or other method of adhering the top clear/transparent layer to the base layer 502 in the required size to accommodate the PV panels 114 as well as any other connections and necessary attachments. It is contemplated that the floating solar clouds 500 and the sleeves 504 and all DBIPV embodiments could be sprayed with a PV ink/paint thus eliminating the use of any PV panels 114.

    [0190] Referring to FIGS. 26 and 30 to 32, various possibilities for forming the floating solar clouds 500 are shown, both in horizontal/vertical configurations or any angles in between. The floating solar cloud 500 may be connected to supports 506, such as steel or composite plastic wires or cables or guides/rails, so that they could be opened and closed as and when required or closed to avoid inclement weather and similar techniques and technology described above for mobile solar tree 100 and the mobile solar vessel 200. These configurations may be used vertically and/or horizontally and may be stretched over large roofs or walls from appropriate supports to allow the PV panels 114 to be opened and closed as shown in the figures. Perforations or other cut-outs could be made in the bellows to allow for the wind to pass through and reduce the stresses on the PV panels 114. The floating solar cloud 500b shown in FIG. 26 could have double PV panels 114 fixed back-to-back when the floating solar cloud 500b are in such a position so that the light would be able to shine on both sides.

    [0191] The horizontal/vertical opening and closing mechanisms as shown in FIGS. 30 to 32 use supports 506 to open and close the floating solar cloud 500 as and when required. Other methods are also possible for both manual and mechanical operation (e.g. similar to how awnings are extended to shade areas).

    [0192] With respect to the DBIPVB 600, many configurations and embodiments are possible, including horizontal and vertical configurations that may be installed over windows in a building to provide shade and energy. They may also be fixed or closeable. One such embodiment is shown in FIG. 36, which shows an embodiment of the DBIPVB 600 attached to a lamppost 602. It is also possible to have more than one of the DBIPVB 600 installed on the lamppost 602. In addition, storage batteries and software programs (e.g. similar to those used for opening and closing as the mobile solar tree 100 and the mobile solar vessel 200) may also be included.

    [0193] FIGS. 33 to 35 show rectangular embodiments of the PV panels 114 of the DBIPVB 600 with a width (b) and a length of (a). When the length (a) is 2 m, and the width (b) is 1 m, then the area of each of the PV panel 114 would be 2 m.sup.2, which is the area it occupies on the wall when closed. Therefore, with a 20-leaf DBIPVB 600 containing 20 PV panels 114 fitted, the total PV area would be a total area of 40 m.sup.2. However, when it is opened, it would only occupy or require an area of 4 m.sup.2 of wall (either vertically or horizontally). Thus, by using thin, light, and flexible PV panels 114 at 3.5 kg/m.sup.2 (the PV panels 114 may have a weight ranging from 0.3 kg/m.sup.2 to 3.5 kg/m.sup.2 each), the DBIPVB 600 may have a total weight of about 80 kg to 160 kg (including the sleeve materials, if any) and may easily be loaded onto any wall or structure. This would allow a 2 m.sup.2 area of a wall or part of a building or structure to expand into a solar panel space more than 10 times its area. Therefore, this would allow almost any buildings/houses or structures to be able to have sufficient solar panels installed to power the structure without having to worry about where they could find the space to deploy the solar panels or how to deploy them.

    [0194] Moreover, when the DBIPVB 600 is closed, the PV panels 114 pack up to a box size with an area of just 2 m.sup.2 and would be hardly noticeable, as the thickness would be relatively small due to the fact that the PV panels 114 are only a few millimeters thick (including the sleeve material, if any). If Z-Arch channels (as described in U.S. Pat. No. 10,240,334 to Paulus, the contents of which are hereby incorporated by reference) are used to launch and support the PV panels as shown in FIGS. 35, 38 to 42, and 48 to 50, then they would stack up into each other as shown in FIGS. 42a and 42b. The PV panels 114 may be fitted into the sleeve 504, which could be fitted into a continuous base fabric and/or could have a light metal or metal/composite frame to help with the support or deployment or have steel wires or other types of high-tension cords to open and close or deploy the panels. Furthermore, this bellows and sleeves method may also be used with the mobile solar tree 100 and the mobile solar vessel 200.

    [0195] Additionally, the size and shape of the DBIPVB 600 may be changed, and the number of PV panels 114 increased or decreased as desired. For example, FIGS. 37 and 38 show the DBIPVB 600 extended or deployed vertically in a different style. These configurations could be used vertically and/or horizontally.

    [0196] FIGS. 38 to 40 show embodiments of the DBIPVB 600 where the PV panels 114 are shorter than the Z-Arch channels. This may allow air and wind to pass through while also avoiding having the PV panels 114 proximate to the ends of the DBIPVB 600 have creases to make more use of the exposure of the PV panels 114.

    [0197] Preferably, the DBIPVB 600 would generally be installed at an angle greater than 45 degrees to the horizontal. This would enable the PV panels 114 to get almost as much exposure to the sun as when then PV panels 114 are arranged horizontally flat, and the angle could be brought closer to the horizontal by spreading the individual bellows of DBIPVB 600 wider or differently (e.g. as shown in FIGS. 38 to 40) and also by changing the size of the length (a) and/or the width (b), as shown in FIG. 33.

    [0198] The indicative opening and closing mechanisms for the DBIPVB 600 is shown in FIGS. 39 to 40 and 48 to 50. The DBIPVB 600 is opened and closed using a channel at the top to provide the strength and support. There are many opening and closing mechanisms possible, both manual and automatic. For example, the Z-Arch channel may be used, as it can fit into each other when closed for compactness and also has high strength when opened. The DBIPVB 600 may be manufactured in the form of a box, with the Z-Arch channels and sleeves ready. The top front cover of the box would open and attach to the wall when totally open, while the bottom back end of the box could be a frame or anchored to the wall or structure and would not move. The PV panels 114 may be added in the box at this time or at some later time. Other types of channels or supports besides the Z Arch channels may also be used.

    [0199] The thickness and weight of the box unit will depend on the size and number of PV panels 114 and may be made of composite plastics for strength and light weight. The sleeves 504 with the PV panels 114 may have an average thickness of 5 to 7 mm. Therefore, a 20-panel box of 2 m.sup.2 may be around 20 cm thick, while the weight would vary depending on the number of PV panels 114 inserted. They may be inserted after the box is fitted on the wall or structure, which would make the installation much easier.

    [0200] Many current materials used for PV panels 114 may pose environmental problems as they are difficult to recycle. Better in this regard are the OPV (organic photovoltaic) materials, but these still have low efficiency and are more costly. Panels made from silicon fiberglass are one new type with high efficiency and lower cost and are more environmentally friendly, providing about 170 watts per m.sup.2 per hour with a weight of 3.5 kg/m.sup.2. A single PV panel 114 with the area of 2 m.sup.2 (1 m×2 m) would give an output of approximately 340 w/m/hr and when attached to the DIPVB 600 of 20 panels, they would have a total output of 6,800 W/hr, which is sufficient to power 3 two-bedroom 150 m.sup.2 apartments with a three-bedroom dwelling of around 350 m.sup.2, especially in sunny locations such as California.

    [0201] FIGS. 43 to 47 show embodiments of the solar tree bellows 700 where the top comprises a full circular bellows 702 raised on a bellows stem 704 with a bellows base 706. The solar tree bellows 700 is similar in description and details to the DBIPVB 600 when open but with a full circular effect. The bellows base 706 and bellows stem 704 shown in FIGS. 43 and 45 are indicative and may be similar to the mobile solar tree 100. Alternatively, it may be modified where the bellows stem 704 is composed of two concentric cylinders one inside the other (as shown in FIGS. 48 to 50), or even outside each next to the other as in FIGS. 43-46 to support the weight of the circular bellows 702. The bellows base 706 may be as shown or a have a multitude of other designs. It may also have mobility as in the mobile solar tree 100.

    [0202] Referring to FIG. 43, the circular bellows 702 of the solar tree bellows 700 preferably close downwards and inwards, as shown in FIGS. 48 to 50. FIG. 45 shows the solar tree bellows 700 in the final stages of closing. The solar tree bellows 700 may also be closed flat similar to the DBIPVB 600 and may resemble the shape shown in FIGS. 29 or 33b or 46c and 46d, but with the bellows stem 704 in the center. Many other closing and opening designs are possible, both manual and automatic.

    [0203] The energy calculation for the solar tree bellows 700 is similar to that for the DBIPVB 600 but with a higher output as the solar tree bellows 700 would typically be larger. Similar various and alternative configurations can be adopted here as in the case with the DBIPVB 600. As an example, FIGS. 43 and 44 show a solar tree bellows 700 with 28 leaves. If each leaf is approximately 2 m.sup.2 in surface area, then the total area of the PV panels 114 would be approximately 56 m.sup.2. Where the PV panels 114 have an output of 340 w/m/hr each, the solar tree bellows 700 may produce approximately 19,040 w/hr, which is almost 3 times the energy produced by the DBIPVB 600 shown above and may power around 11 units with an area of about 150 m.sup.2 each (such as two-bedroom apartment/houses including air conditioning). The solar tree bellows 700 may only require a footprint of 16 m.sup.2 above ground level, at the dimensions of 4 m×4 m bellows, but could occupy only 4 m.sup.2 of ground for a base or maybe even less. This could constitute a saving of over 82.3% of land in comparison to the traditional ground-mounted PV panel systems, which would occupy more than 16 square meters, with a PV area of only 16 square meters to allow for distances between panels.

    [0204] Where the DBIPVB 600 is installed in conjunction with the lamppost 602, such arrangements may have a fairly large power output, especially when installed on lampposts 602 that are tall, with the PV panels 114 arranged with many layers and staggered configurations, as shown in FIG. 36b. The lampposts 602 may be fixed, mobile, or transportable. Those bellows may have different colours on the bottom layer, which is what is usually seen from the street level so they can be used to add a colourful and joyous mood as well as advertising to generate revenues. This may be useful in locations such as Africa or other remote locations where there is an abundance of sunshine but electricity is hard to find. Alternatively, they may be used to quickly power communities after hurricanes down the power lines. This is also a novel solution, where now solar panels could be installed anywhere on and around a building and not only on the roof to satisfy the California building code.

    [0205] It is also possible to add wind turbines to the solar tree bellows 700, thus turning the solar tree bellows 700 into a wind power generator when wind is available.

    [0206] The solar tree bellows 700 and the floating solar clouds 500 may be installed on poles and opened to a longitudinal or circular embodiment to shade agricultural land or other grounds and also to generate energy on buildings with large rooftop areas, such as warehouses and shopping malls. It is also possible to use them on agricultural land as it frees up the land below and shades it or to help with deforestation and/or desertification. They may also be used to protect rainforests when deployed above the trees, as shown in FIGS. 46, 47, and 51, They may be closed when necessary or during inclement weather or even packed and stowed away before the onset of storms or hurricanes. They can then be opened and deployed after the storm to generate electricity with little delay.

    [0207] The embodiments of the DBIPV 300 (i.e. the floating solar cloud 500, the DBIPVB 600, and the solar tree bellows 700) may be used in both the vertical and horizontal configurations when the constituent PV panels 114 have sufficient transparency and also in the multilayered embodiment.

    [0208] In another embodiment, a water sprinkler system may be incorporated to clean the PV panels 114 when necessary. The water sprinkler system may also act as a fire extinguishing system should there be such a need, as PV panels 114 have the possibility of overheating or catching fire. Other firefighting systems/methods could be used as well.

    [0209] Yet another embodiment is the use of the DBIPV 300 in a system to prevent forest fires or help to quell them where the DBIPV elements would be deployed in a network of solar trees/sails and other DBIPVs 300 spread over a large area in and around a forest connected in a grid with sensors preferably in a wireless mode or via satellite to detect and prevent forest fires. The DBIPV 300 would supply power to the system and to a connected network of pumps to draw water from a network of canals and/or reservoirs and/or from ground water to moisten the grounds when they become too dry to prevent the fires or to quell the fires or manage them should they start. This system can also work with a network of canals acting as a firewall or a series of firewalls designed to stop or prevent the fire from spreading. The sensors in the system, both in the DBIPV 300 and/or outside them could be programmed to detect when the earth/plants become too dry to moisten them to prevent the fires or/and detect forest fires as early as possible and activate the system to fight the fire quickly and prevent it from spreading. This can be made possible due to the portability of the solar tree/sails and other DBIPV, which could be moved and located at various positions to help power the sensors and the pumps which otherwise would be impossible or very difficult due to the vast areas of most forests worldwide and this could be a timely solution to the Californian and Australian forest fires as well as others in Europe, Asia and South America and other parts of the world.

    [0210] It will be appreciated by those skilled in the art that the preferred embodiment has been described in some detail but that certain modifications may be practiced without departing from the principles of the invention.
