Summary of the Invention

Problems to be Solved by the Invention

[0011] The inventions of Patent Documents 1 to 8 have a lack of patterns in the installation state of the solar cell panels, and it is difficult to flexibly respond to an environment where the solar cell panels need to avoid obstacles.

[0012] The present invention has been made paying attention to these problems, and provides a solar power generation device and a solar power generation method capable of enriching the installation pattern of solar power generation panels and flexibly avoiding obstacles.

Means for Solving the Problems

[0013] The solar power generation device of the present invention includes a housing having a framework, an actuator provided on the upper part of the housing, and at least a first panel body, a second panel body, and a third panel body connected to the housing via the actuator, and a panel structure in which the first panel body to the third panel body can take a stored state or a deployed state, and the actuator has a pair of sliders that slide along the axial direction of the framework, a driving side link member and a driven side link member, the lower part of the driving side link member is pivotally attached to the slider, the upper part of the driven side link member is pivotally attached to the driving side link member, and the lower part of the driven side link member is pivotally attached to the framework, a pair of link mechanisms, a vertical link member that extends in the vertical direction and has a lower part pivotally attached to the upper part of the driving side link member and an upper part pivotally attached to the first panel body and moves up and down as the slider moves laterally, and a pair of opening and closing drive parts that pivotally attach to the vertical link member and the second panel body, and the vertical link member and the third panel body and drive the second panel body and the third panel body to open and close with respect to the first panel body, and a pair of inclination angle and height changing parts that pivotally attach to the framework and the first panel body and change the inclination angle and / or height of the first panel body.

[0014] Thereby, the present invention can enrich the installation pattern of solar power generation panels and flexibly avoid obstacles.

[0015] It is preferable to perform posture control in which the vertical link member moves, the link mechanism deforms, the second panel body or the third panel body is in a vertical state, and the first panel body is in an inclined state or a horizontal state by driving the pair of inclination angle and height changing parts.

[0016] Accordingly, even if the second panel body or the third panel body remains in a vertical state, the other panel bodies can be set at an optimal inclination angle, so that the power generation efficiency can be increased even in the presence of obstacles.

[0017] It is preferable that when the pair of opening and closing drive parts are driven, the first panel body, the second panel body, and the third panel body perform attitude control to be flush or at a specific angle.

[0018] Accordingly, the second panel body and the third panel body can be set at their respective optimal inclination angles, and the power generation efficiency can be increased whether there are obstacles or not.

[0019] It is preferable that the pair of opening and closing drive parts include a first cylinder rotatably axially attached to the vertical link member and the second panel body, and a second cylinder rotatably axially attached to the vertical link member and the third panel body.

[0020] Accordingly, the present invention can realize a compact drive structure.

[0021] It is preferable that the pair of inclination angle / height changing parts include a third cylinder rotatably axially attached to one side part of the framework and the first panel body, and a fourth cylinder rotatably axially attached to the other side part of the framework and the first panel body.

[0022] Accordingly, a compact drive structure can be realized, and the patterns of the deployed states of the first panel body to the third panel body can be increased.

[0023] The pair of opening / closing drive units includes a first cylinder pivotally attached to the vertical link member and the second panel body, and a second cylinder pivotally attached to the vertical link member and the third panel body. The pair of inclination angle / height change units includes a third cylinder pivotally attached to the frame and one side portion of the first panel body, and a fourth cylinder pivotally attached to the frame and the other side portion of the first panel body. It is preferable that the first cylinder and the third cylinder intersect three-dimensionally, and the second cylinder and the fourth cylinder intersect three-dimensionally.

[0024] Thereby, a more compact drive structure can be achieved.

[0025] It is preferable that there are a plurality of drive-side link members of the link mechanism, and the drive-side link members are provided in parallel with a specific interval therebetween.

[0026] Thereby, the loads from the first panel body to the third panel body applied to the link mechanism are dispersed, the load balance of the first panel body to the third panel body is stabilized, and their movements are smoothed.

[0027] The first panel body has a solar panel that can be lifted or have its tilt angle adjusted in the upper space of the housing, and can assume either a horizontal state or a tilted state, by the deformation of the link mechanism driven by the tilt angle and height changing section. The second panel body has a side portion that is connected to a side portion of the first panel body by a connector, and in the space on the right side of the housing, it can rotate clockwise or counterclockwise around a first rotation axis along the side portion of the first panel body when the opening and closing drive section is driven, and can assume any of a horizontal state, a tilted state, or a vertical state in a front view, having a solar panel. The third panel body has a side portion that is connected to the other side portion of the first panel body by a connector, and in the space on the left side of the housing, it can rotate clockwise or counterclockwise around a second rotation axis along the other side portion of the first panel body when the opening and closing drive section is driven, and can assume any of a horizontal state, a tilted state, or a vertical state in a front view, preferably having a solar panel.

[0028] Thereby, the present invention can provide a gap between the first panel body to the third panel body and the housing, suppressing direct sunlight irradiation and direct rainfall on the storage housing. Thereby, the present invention can improve the installation environment of the housing.

[0029] It is preferable that the second panel body and the third panel body are divided into a plurality in the front - rear direction or the left - right direction, and each divided body can be folded in the front - rear direction or the left - right direction.

[0030] Thereby, the present invention can achieve a compact transportation state and can accommodate different loading weights and dimensions of the vehicle used during transportation. Also, power generation can be performed with only some of the divided bodies folded, and during power generation, obstacles can be avoided more flexibly. When each divided body is deployed, more power can be obtained compared to the folded state.

[0031] It is provided with a panel fastening member stored directly below the first panel body, and the panel fastening member is preferably fastened to the second panel body or the third panel body that is flush with the first panel body when deployed, using a fastener.

[0032] This facilitates the change operation between the deployed state and the stored state.

[0033] The solar power generation method of the present invention is a solar power generation method in which the first to third panel bodies of the solar power generation device are in a stored state or a deployed state, and solar power generation is possible in both the state of being loaded on a vehicle and the state of not being loaded on a vehicle. It includes: Step 1 of horizontally deploying the second panel body or the third panel body in the stored state using the pair of opening and closing drive parts so that it is flush with the first panel body; Step 2 of pulling out the panel fastening member stored under the first panel body and fastening the panel fastening member to the second panel body or the third panel body using a fastener; Step 3 of driving the inclination angle / height changing part and adjusting the inclination angle and / or height of the first to third panel bodies according to the irradiation situation of sunlight. It is preferably provided with these steps.

[0034] This enables the deployment work and the storage work to be carried out more quickly.

[0035] Another solar power generation method of the present invention is a solar power generation method in which the first to third panel bodies of the solar power generation device are in a stored state or a deployed state, and solar power generation is possible in both the state of being loaded on a vehicle and the state of not being loaded on a vehicle. It includes: Step 1 of driving the inclination angle / height changing part and adjusting the inclined first panel body in the horizontal direction; Step 2 of releasing the fastening between the panel fastening member stored under the first panel body and the second panel body or the third panel body and retracting the panel fastening member; Step 3 of vertically adjusting the second panel body or the third panel body using the pair of opening and closing drive parts. It is preferably provided with these steps.

[0036] This enables the deployment work and the storage work to be carried out more quickly.

[0037] Another solar power generation method of the present invention is a solar power generation method in which the first to third panel bodies of the solar power generation device are in a stored state or a deployed state, and solar power generation is possible in both a state of being loaded on a vehicle and a state of not being loaded on a vehicle. It is preferable to include an inclination angle and height adjustment step of adjusting the inclination angle and / or height of the first panel body to the third panel body by driving the inclination angle and height changing part.

[0038] Thereby, the attitude control of the inclination angle and the height can be simplified.

[0039] Another solar power generation method of the present invention is a solar power generation method in which the first to third panel bodies of the solar power generation device are in a stored state or a deployed state, and solar power generation is possible in both a state of being loaded on a vehicle and a state of not being loaded on a vehicle. A storage state transition step of performing attitude control to a storage state in which the first panel body is in a horizontal state and the second and third panel bodies are in a vertical state by driving the pair of opening and closing drive parts and the inclination angle and height changing part from the deployed state is preferably provided.

[0040] Thereby, in the present invention, the attitude control from the deployed state to the stored state can be simplified.

[0041] It is preferable that the second panel body and the third panel body are divided into a plurality in the front - rear direction or the left - right direction, each divided body is foldable in the front - rear direction or the left - right direction, and a divided body deployment step of deploying each folded divided body to be flush is provided.

[0042] Thereby, a compact transportation state is realized, and it can be loaded even on a small vehicle. When each divided body is deployed, more power can be obtained than in the folded state. In addition, by variously combining the deployed state and the folded state of the divided body, obstacles can be avoided more flexibly even during power generation, and power generation can be performed efficiently.

Embodiments for Carrying Out the Invention

[0044] Hereinafter, with reference to FIGS. 1 to 33, the photovoltaic power generation device 1 according to Embodiment 1 of the present invention (hereinafter referred to as the device 1) will be described in detail.

[0045] This device 1 includes a housing 2 and a framework 3 of the housing 2 (see FIG. 2(b)). The housing 2 is a rectangular box containing a battery (not shown) having a roof 21, side portions 22, a bottom portion 23, and a door 24 provided on the side portions 22. As shown in FIG. 2(b), the framework 3 includes support members 30 in the left-right direction X constituting the upper part, support members 31 in the front-rear direction Y, support members 32 in the left-right direction X and the front-rear direction Y constituting the bottom, and vertical support members 33 connecting the support members 30 to 32. The device 1 stores electricity from the first panel body 5, the second panel body 6, and the third panel body 7 in a battery (not shown).

[0046] This device 1 further includes an actuator AC, a first panel body 5, a second panel body 6, and a third panel body 7.

[0047] The first panel body 5 can move up and down or adjust the inclination angle θ (see FIG. 20(a)) with respect to the left-right direction X of the housing 2 in the upper space of the housing 2, and can take either a horizontal state or an inclined state. It has four solar cell panels 50 and a frame for supporting the solar cell panels 50.

[0048] The second panel body 6 has a side portion 61 that is coupled to a side portion 51 of the first panel body 5 by a coupler 53 (see FIG. 5). In a space on the right side of the housing 2 (the left side when viewed from the front in FIG. 1(a)), it can rotate clockwise or counterclockwise around a first rotation axis Y1 (see FIG. 3) along the side portion 51 of the first panel body 5, and can be in any one of a horizontal state, an inclined state, or a vertical state when viewed from the front. It has four solar cell panels 60 and a frame that supports the solar cell panels 60.

[0049] The third panel body 7 has a side portion 71 that is coupled to the other side portion 52 of the first panel body 5 by a coupler 54. In a space on the left side of the housing 2 (the right side when viewed from the front in FIG. 1(a)), it can rotate clockwise or counterclockwise around a second rotation axis Y2 (see FIG. 3) along the other side portion 52 of the first panel body 5, and can be in any one of a horizontal state, an inclined state, or a vertical state. It has four solar cell panels 70 and a frame that supports the solar cell panels 70.

[0050] As shown in FIGS. 12 to 14, the second panel body 6 and the third panel body 7 are divided into a plurality of parts in the front-rear direction Y. By rotating each divided body in the R direction (see FIGS. 3 and 14), it can be folded or unfolded in the front-rear direction Y. In this embodiment, the second panel body 6 and the third panel body 7 are divided in the front-rear direction Y, but it can also be configured to be divided in the left-right direction X and folded or unfolded in the left-right direction X.

[0051] Thereby, the device 1 can respond to the specific loading weight of the vehicle 100 used during transportation, for example, less than 1 ton or the size of the loading capacity, by folding the divided bodies of the second panel body 6 and the third panel body 7 inward in the front-rear direction X as needed. Also, by variously combining the unfolded state and the folded state of the divided bodies, it is possible to more flexibly avoid obstacles even during power generation and efficiently generate power. When each divided body is unfolded from the folded state, the device 1 can obtain more power than when in the folded state. The dimensions of the device 1 can be set within the range not violating the Road Traffic Law.

[0052] In FIGS. 1, 2(a), 3, 4, 11(a), 12, 13, and 14, the second panel body 6 and the third panel body 7 are folded inward, and in the other drawings, they are unfolded and flush. In FIGS. 1 to 5, 11 to 14, 25 to 27, the first panel body 5 is in a horizontal state, and in FIGS. 15 to 19, 20 to 24, it is in an inclined state. In FIGS. 1, 2(a), 3, 4, 15 to 19, the second panel body 6 and the third panel body 7 are in a vertical state. The second panel body 6 and the third panel body 7 are in an inclined state in FIGS. 20 to 24 and in a horizontal state in FIGS. 11 to 14, 25 to 27.

[0053] As described above, the second panel body 6 and the third panel body 7 are divided into a plurality of parts in the front-rear direction, and each divided body can be folded in the front-rear direction Y, and the folded divided bodies can be unfolded to be flush.

[0054] Thereby, a compact transportation state is realized, and it can be loaded even on a vehicle 100 with a specific weight or volume or less. When each divided body is unfolded, more power can be obtained than in the folded state. Even when each divided body is folded and loaded on the vehicle 100 (see FIG. 28), power can be generated by the four solar panel panels 50 of the first panel body 5. In that case, however, the contribution of the other panel bodies to power generation is low. For a vehicle 100 with a specific weight or volume or more, the necessity of the folded state is low.

[0055] In FIGS. 1 to 4 and the like, the first panel body 5, the second panel body 6, and the third panel body 7 each have four solar cell panels. The power of each panel is 200 W, and a total of 12 panels can generate a maximum of 2400 W of electricity. This power can be changed as appropriate. There are a plurality of batteries (not shown), for example, six, each with 3 KW·hr, for a total of 18 KW·hr, and an input section, an output section, and a control device are also provided. The input power has a determined input upper limit value. When the power exceeds the input specification, the current and voltage are adjusted and input. The device 1 includes a controller for controlling the voltage and current of the battery in the housing 2 and an operation panel mounted in the housing 2. The battery is exemplified by a large-capacity portable battery. By opening and closing the door 24, etc., the battery can be pulled out of the housing 2.

[0056] As shown in FIGS. 1 to 4, in its stored state, the device 1 is in a posture in which eight solar cell panels of the second panel body 6 and the third panel body 7 among the total 12 solar cell panels are folded inward, and it can appropriately respond to the storage or transportation of the device 1. Even at that time, among the 12 panels, at least the four solar cell panels 50 of the first panel body 5 can always generate electricity if sunlight is irradiating. By adapting and controlling the postures of the first panel body 5, the second panel body 6, and the third panel body 7 to the environment, any of various deployment states exemplified by deployment states 1 to 6 can be selected and installed. The four solar cell panels 50 of the first panel body 5 can always generate electricity even during storage and transportation.

[0057] According to the situation of the installation location, the size of the vehicle 100, and the sunlight irradiation situation, the device 1 can select an appropriate deployment pattern from various deployment states including deployment states 1 to 6.

[0058] As shown in FIGS. 11(a), 12 to 14, the deployment state 1 is a state in which the first panel body 5 to the third panel body 7 are in a horizontal state and the light-receiving surfaces of the second panel body 6 and the third panel body 7 are folded inward so as to face each other.

[0059] As shown in Fig. 11(b), in the deployed state 2, the second panel body 6 and the third panel body 7 are deployed outward and made flush in the deployed state 1.

[0060] As shown in Figs. 15 to 18, in the deployed state 3, by driving the actuator AC, one side of the first panel body 5 is raised and lowered to be in an inclined state, and the second panel body 6 and the third panel body 7 maintain a vertical state.

[0061] As shown in Fig. 20(a) and Figs. 21 to 24, in the deployed state 4, the second panel body 6 and the third panel body 7 are deployed in the deployed state 3 to be flush with the first panel body 5 and in an inclined state. In this case, the first panel body 5 to the third panel body 7 may not be flush but may be provided with a specific angle to each other. If the second panel body 6 and the third panel body 7 are folded to a vertical state from the deployed state 4 of the device 1, the device 1 will be in the deployed state 3.

[0062] As shown in Fig. 20(b), in the deployed state 5, the inclination direction of the first panel body 5 to the third panel body 7 is reversed in the deployed state 4.

[0063] As shown in Figs. 25 to 27, in the deployed state 4 or 5, by adjusting the height H of one side of the first panel body 1 to the third panel body 7, the inclined angle θ is made horizontal. Here, the height H of the first panel body 5 to the third panel body 7 is increased. In other words, the deployed state 6 is a state in which the height H of the first panel body 5 to the third panel body 7 is increased while remaining in a horizontal state in the deployed state 2.

[0064] The structure and operation of the actuator AC of device 1 will be described. As shown in FIGS. 5, 19, and 24, the actuator AC of device 1 is attached to the support member 30 in the left - right direction X (in this embodiment, the second support member 30 from the end in FIG. 2(b)), and it is also possible to be attached to the support member 31 in the front - rear direction Y. Along the support member 30, a pair of sliders 4A and 4B that slide in the X direction (this also holds true for the case of the front - rear direction Y, but the illustration is omitted), a pair of link mechanisms 8A and 8B, a vertical link member 9, a pair of opening - closing drive units 10A and 10B, and inclination angle and height change units 11A and 11B are provided. Hereinafter, the actuator AC will be described in detail.

[0065] As shown in FIGS. 5, 19, and 24, the pair of link mechanisms 8A and 8B have drive - side link members 81A and 81B and follower - side link members 82A and 82B. The drive - side link members 81A and 81B are pivotally attached to the pair of sliders 4A and 4B respectively in a rotatable manner, and the upper parts of the follower - side links 82A and 82B are pivotally attached to the drive - side links 81A and 81B respectively, and the lower parts are pivotally attached to the support member 30. They are mechanisms arranged side - by - side in the axial direction.

[0066] As shown in FIGS. 5, 19, and 24, one end 90 of the vertical link member 9 is pivotally attached to the drive - side link members 81A and 81B of the pair of link mechanisms 8A and 8B respectively in a rotatable manner, and the other end 91 is pivotally attached to the first panel body 5 in a rotatable manner. It has a structure that extends in the vertical direction and moves up and down in the vertical direction YQ. Thereby, device 1 can realize a compact drive structure by using the vertical link member 9.

[0067] As shown in FIGS. 5, 8 to 10, 19, 24, and 27, a pair of opening / closing drive units 10A and 10B are rotatably attached to a vertical link member 9 and connectors 53 and 54 attached to a second panel body 6 and a third panel body 7, are extendable and contractible in the ZQ direction, and independently drive the second panel body 6 and the third panel body 7 with respect to the first panel body 5. The connectors 53 and 54 are plate materials, are respectively fixed to the second panel body 6 and the third panel body 7, and their upper parts are rotatably attached to connectors 57 and 58, respectively. As shown in FIGS. 8 to 10, one end of a pair of links 10C and 10D is rotatably attached to the vertical link member 9, and the other end is rotatably attached to the lower ends of connectors 55 and 56 which are plate materials. The upper ends of the connectors 55 and 56 are rotatably attached to the connectors 57 and 58, respectively. The connectors 57 and 58 are fixed to the first panel body 5. With this structure, even when driving the first panel body 5 of the tilt angle / height change parts 11A and 11B, the second panel body 6 and the third panel body 7 can be maintained vertical. Also, when the second panel body 6 and the third panel body 7 are opened and closed, the operations of the pair of opening / closing drive units 10A and 10B can be assisted. The shafts 59A and 59B (see FIG. 9) of the vertical plate material 9, the links 10C and 10D, and the connectors 55 and 56 are each configured to maintain a parallelogram or a rectangle.

[0068] A pair of opening / closing drive units 10A and 10B are composed of a first cylinder 10A that rotatably attaches the vertical link member 9 and the second panel body 6, and a second cylinder 10B that rotatably attaches the vertical link member 9 and the third panel body 7. Thereby, a compact drive structure can be achieved, and the structure of the apparatus 1 in the transportation state and the installation state can be made even more compact.

[0069] As shown in FIGS. 5, 19, and 24, a pair of tilt angle / height change parts 11A and 11B are materials that are extendable and contractible in the PQ direction, with their lower ends respectively connected to a shaft attachment part 31a (see FIG. 2(b)) of a support member 31 in the front-rear direction Y, and their upper ends rotatably attached to connection parts 11C and 11D (see FIG. 5) fixed to the first panel body 5, and are rotatably attached to one side part 51 and the other side part 52 of the first panel body 5, respectively.

[0070] As shown in FIGS. 5, 19, and 24, the tilt angle and height change parts 11A and 11B include a third cylinder 11A pivotally attached to one side of the support member 31 in the front-rear direction Y and one side 51 of the first panel body 5, a first side of the support member 31 in the front-rear direction Y facing the support member 31 to which the third cylinder 11A is pivotally attached, and a fourth cylinder 11B pivotally attached to the other side 52 of the first panel body 5. When the tilt angle and height change parts 11A and 11B are driven, the vertical link member 9 moves, the link mechanisms 8A and 8B deform, the opening and closing drive parts 10A and 10B are driven, and the first panel body 5 to the third panel body 7 are lifted and / or the tilt angle θ of the first panel body 5 to the third panel body 7 with respect to the left-right direction X of the housing 2 is adjusted.

[0071] Thereby, the device 1 can generate electricity both during transportation and installation, can realize a compact drive structure, enrich the deployment patterns of the first panel body 5 to the third panel body 7, and can flexibly avoid obstacles.

[0072] It is preferable that the first cylinder 10A and the third cylinder 11A are three-dimensionally crossed, and the second cylinder 10B and the fourth cylinder 11B are three-dimensionally crossed. Thereby, a more compact structure is realized.

[0073] As shown in FIGS. 1 to 33, with a pair of opening / closing drive units 10A and 10B and a pair of tilt angle / height change units 11A and 11B, the first panel body 5 can be in a horizontal state or a tilted state, and the second panel body 6 and the third panel body 7 can be in a horizontal state, a tilted state, or a vertical state, and the height can be adjusted. For example, attitude control can be performed such that the second panel body 6 or the third panel body 7 is in a vertical state and the first panel body 5 is in a horizontal or tilted state in the left-right direction X. The pair of opening / closing drive units 10A and 10B have a gas spring structure and assist in the deployment of the second panel body 6 or the third panel body 7 by utilizing the repulsive force of the gas spring or the like. In the present embodiment, since the opening / closing drive units 10A and 10B have a gas spring structure, basically, the deployment and storage of the second panel body 6 and the third panel body 7 are performed manually, and the gas springs of the opening / closing drive units 10A and 10B assist the manual operation. However, it can also be an electric structure or the like to perform the deployment and storage operations completely automatically. The tilt angle / height change units 11A and 11B are electric cylinders, and the power utilizes the electricity of a storage battery (not shown) built in the housing 2, and the power supply structure can be simplified. The tilt angle / height change units 11A and 11B are electric cylinders because the hydraulic cylinder becomes large and is expensive.

[0074] As shown in FIGS. 28 to 33, the device 1 is loaded on the vehicle 100 and transported to the destination. Power generation can be effectively performed even during transportation by the vehicle 100. As shown in FIG. 28, in the storage state where the second panel body 6 and the third panel body 7 are folded inward, it can be loaded on a vehicle 100 with a small loading weight and loading volume, such as a truck with a weight of less than 1 ton. Within the scope not deviating from the Road Traffic Law, the folding mode can be set as appropriate. When loading on the vehicle 100 in such a state, the four solar cell panels 50 of the first panel body 5 generate electricity, while the others do not contribute much to power generation. When the vehicle 100 is in a stationary state, with the device 1 still loaded on the vehicle 100, as shown in FIGS. 30, 31, 32, and 33, the second panel body 6 and the third panel body 7 can also be deployed and can be efficiently used for power generation while moving flexibly.

[0075] A pair of opening / closing drive units 10A and 10B, and tilt angle / height change units 11A and 11B perform posture control to make the first panel body 5, the second panel body 6, and the third panel body 7 flush or form a specific angle with each other. Thereby, when there are no or few obstacles, the power generation efficiency can be increased.

[0076] The first panel body 5 to the third panel body 7 can be given appropriate angles θ and heights H respectively by driving the actuator AC according to the installation situation. The adjustment of the angle θ is performed by a combination of the link mechanisms 8A and 8B, a pair of opening / closing drive units 10A and 10B, and the tilt angle / height change units 11A and 11B which are electric cylinders installed on the left and right. In addition to the angle adjustment, the installation height H of the first panel body 5 to the third panel body 7 can be increased within a certain range, and an improvement in power generation efficiency is expected in situations where shade is a concern. The adjustment of the height H is possible within the expansion and contraction range of the left and right electric cylinders of the tilt angle / height change units 11A and 11B. (However, when increasing the height H, the adjustment range of the angle θ may narrow in inverse proportion to the extension of the left and right electric cylinders of the tilt angle / height change units 11A and 11B.) Thereby, a large-capacity power generation amount and a compact structure can be realized.

[0077] The solar panels of the first panel body 5 to the third panel body 7 (here, a total of 12 sheets) can take panel forms of various patterns. The panel form of the device 1 can be in various forms such as a storage state or deployment states 1 to 6. The device 1 can select and use at least one of the layout shapes of the deployment states 1 to 6 according to various installation locations and usage environments. When there are obstacles that hinder the deployment of the first panel body 5 to the third panel body 7 of the device 1, some panel bodies can be made vertical or inclined, or some panel bodies can be folded inward and deformed to avoid the obstacles. On the other hand, when there are no obstacles, it can be deployed. The device 1 can select various patterns according to the situation of the installation location. When there are obstacles that hinder the deployment of the panel, the corresponding panel body does not deploy, and when there are no obstacles, it can deploy. The device 1 can enrich the variations of the panel deployment by combining inclined panels and vertical panels. Even when all the panels are deployed, the device 1 can select various pattern variations. Even when there are space problems, the device 1 does not need to take up width. In this way, the device 1 can select and use the layout shape according to various installation locations, usage environments, etc.

[0078] Next, an embodiment of the solar power generation method of the present invention will be described. It is a solar power generation method capable of solar power generation in both the state where the first panel body 5 to the third panel body 7 of the device 1 are in a storage state or a deployment state, and the state of being loaded on the vehicle 100 and the non-loaded state of not being loaded on the vehicle 100.

[0079] According to another embodiment of the present invention, it is a solar power generation method in which the inclination angle θ and height H of the first panel body 5 to the third panel body 7 are adjusted by the expansion and contraction of the inclination angle / height change parts 11A and 11B, and the first panel body 5 to the third panel body 7 of the device 1 are in a storage state or a deployment state.

[0080] One aspect of the solar power generation method is, for example, a solar power generation method composed of the following steps 1 to 3.

[0081] Step 1 is to use a pair of opening / closing drive units 10A and 10B that utilize the repulsive force of gas springs to assist in the horizontal deployment of the second panel body 6 or the third panel body 7 in the stored state so that they are flush with the first panel body 5. In this embodiment, since the opening / closing drive units 10A and 10B have a gas spring structure, basically, the deployment and storage of the second panel body 6 and the third panel body 7 are performed manually, and the gas springs of the opening / closing drive units 10A and 10B assist the manual operation. However, it can also be an electric structure or the like to perform the deployment operation completely automatically.

[0082] Step 2 is, after making them flush by the above deployment, to pull out a plurality of panel fastening members 12 (see FIG. 14(c)) stored under the first panel body 5 and fasten the plurality of panel fastening members 12 to the frame of the second panel body 6 or the third panel body 7 using fasteners 13 (for example, clamp levers).

[0083] Step 3 is to drive the electric cylinders of the tilt angle / height change units 11A and 11B, move the vertical link members 9, and deform the link mechanisms 8A and 8B to adjust the tilt angle θ and height H of the first panel body 5 to the third panel body 7 according to the sunlight irradiation situation. Thereby, the power generation efficiency can be improved. Also, thereby, the deployment work can be made faster.

[0084] According to another embodiment of the solar power generation method of the present invention, the first panel body 5 to the third panel body 7 of the device 1 are in a stored state or a deployed state, and solar power generation is possible in both the state of being loaded on the vehicle 100 and the state of not being loaded on the vehicle 100. A solar power generation method, comprising: driving the tilt angle / height changing parts 11A, 11B to make the tilted first panel body 5 horizontal (step 1); a plurality of panel fastening members 12 stored under the first panel body 5; and releasing the fastening by the fasteners 13 of the frames of the second panel body 6 or the third panel body 7, and retracting the plurality of panel fastening members 12 (step 2); and using the pair of opening / closing driving parts 10A, 10B to vertically adjust the second panel body 6 or the third panel body 7 (step 3). In step 1, by making the first panel body 5 horizontal, the second panel body 6 and the third panel body 7 that are flush with the first panel body 5 in the deployed state also become horizontal. Thereby, the storage work can be made faster.

[0085] Another solar power generation method of the present invention is a solar power generation method in which the first panel body 5 to the third panel body 7 of the device 1 are in a stored state or a deployed state, and solar power generation is possible in both the state of being loaded on the vehicle 100 and the state of not being loaded on the vehicle 100. The method includes a tilt angle / height H adjustment step (see FIGS. 15, 20, etc.) of adjusting the tilt angle θ and / or height H of the first panel body 5 to the third panel body 7 by driving the tilt angle / height changing parts 11A, 11B. Thereby, the attitude control of the tilt angle θ and the height H can be simplified.

[0086] Another solar power generation method of the present invention is a solar power generation method capable of solar power generation in both a state of being loaded on a vehicle 100 and a state of not being loaded on the vehicle 100, with the first panel body 5 to the third panel body 7 of the device 1 being in a stored state or a deployed state. From the deployed state, by driving a pair of opening and closing drive parts 10A and 10B and inclination angle / height changing parts 11A and 11B, the vertical link member 9 is moved, and the link mechanisms 8A and 8B are deformed, so that the first panel body 5 is in a horizontal state, and the second panel body 6 and the third panel body 7 are in a vertical state. A storage state transition step for performing attitude control to a storage state is provided. Thereby, the attitude control from the deployed state to the storage state can be simplified.

[0087] Another solar power generation method of the present invention is such that the second panel body 6 and the third panel body 7 of the device 1 are divided into a plurality in the front-rear direction Y, each divided body can be folded in the front-rear direction Y, and a divided body deployment step of deploying each folded divided body to be flush is provided. It is a step of further deploying the divided body folded in the front-rear direction Y among the left and right second panel bodies 6 and third panel bodies 7.

[0088] Thereby, a compact transportation state is realized, and it can be loaded even on a small vehicle 100. When each divided body is deployed, more power can be obtained than in the folded state.

[0089] With reference to FIGS. 34 to 36, the configuration of the solar power generation device 201 (hereinafter referred to as the device 201) according to Embodiment 2 of the present invention will be described in detail.

[0090] This device 201 has a structure in which link mechanisms 208A and 208B for additionally installing drive-side link members 283A and 283B are provided in order to increase the operation stability of the link mechanisms 8A and 8B of the device 1. Since the other structures are basically the same as those shown and described in the device 1, those are incorporated by reference, and the common structures are numbered in the 200s, and mainly, the different structures will be illustrated and described. Note that the illustration and description of the members corresponding to the opening and closing drive parts 10A and 10B, etc. are omitted.

[0091] As shown in FIG. 36, the drive-side link members 283A and 283B are each configured in parallel with the drive-side link members 281A and 281B and are connected to the sliders 204A and 204B having rollers and the vertical link member 209. The drive-side link members 283A and 283B are installed in parallel with a space therebetween from the drive-side link members 281A and 281B. By deforming, the loads from the first panel body 5 to the third panel body 7 applied to the link mechanisms 208A and 208B are dispersed, the load balance of the first panel body 5 to the third panel body 7 is stabilized, and their movements are smoothed.

[0092] This embodiment is an example, and it goes without saying that it can be modified without departing from the technical idea of the present invention.
