Description

Vertical photovoltaic power generation system and method of installing the same

[0001] The present invention relates to a vertical photovoltaic power generation system and a method for installing the same. In particular, the present invention relates to a vertical photovoltaic power generation system and a method for installing the same that can be efficiently installed in an area having a specific space, such as the rooftop of a building constructed with a flat slab roof.

[0002] Most Building-Integrated Photovoltaics (BIPV) are designed to be installed on the exterior walls of buildings. This approach is attracting attention as it integrates solar power generation facilities into the building structure to enhance energy efficiency while maintaining aesthetics.

[0003] However, this exterior wall installation method has several fundamental disadvantages. When installed on exterior walls, the efficiency of the photovoltaic power generation system is heavily dependent on the angle of incidence of sunlight, and power generation efficiency can drop significantly depending on the time of day or season. In particular, the amount of sunlight incident on the exterior wall may be limited by the building's geographical location and surrounding environment, often resulting in power generation efficiency falling short of expectations. Furthermore, since exterior wall installation is closely linked to the building's structural design, additional costs and time may be required during the installation process.

[0004] Recently, vertical solar structures are being developed as an alternative to compensate for these drawbacks. Vertical structures are designed by mounting solar panels vertically to generate power from both sides. This method has the advantage of maximizing the incident solar surface area through double-sided panels and collecting sunlight from various angles. Additionally, it offers the benefit of maintaining stable power generation efficiency by being less sensitive to changes in solar incidence depending on the season and time of day.

[0005] However, these vertical solar structures also present challenges during the installation process. Applying vertical structures requires design and construction methods different from conventional exterior wall installations, making the securing of structural stability a critical challenge. In particular, vertically positioned panels are highly susceptible to external environmental factors such as wind, which may necessitate additional support structures to mitigate these effects. This serves as a major cause of increased installation costs and construction complexity.

[0006] Therefore, the problem that the present invention aims to solve is to provide a vertical photovoltaic power generation system and a method for installing the same that solves the aforementioned problem.

[0011] In one embodiment, the front and rear portions of the solar cell string section may each be characterized by having one full string positioned at the top and two half strings positioned at the bottom.

[0012] In one embodiment, the electrode portion is composed of a side electrode and a center electrode, and the front and rear portions of the solar cell string portion may be characterized by having a pair of side electrodes disposed on both sides of the full string and half string, and a pair of center electrodes disposed between the half strings.

[0013] In one embodiment, the side electrode may be characterized by connecting the full string and the half string.

[0014] In one embodiment, the junction box portion may be characterized by being electrically connected to the central electrode.

[0015] In one embodiment, the frame portion may be characterized by including a frame body, a play-prevention projection including a projection that prevents play, and a fastening guide that guides the fastening direction to facilitate fastening to the frame fixing portion of the solar module.

[0016] In one embodiment, the upper folding fixing part may be characterized by accommodating a cable extending from the junction box part.

[0017] In one embodiment, the upper folding fixing part of the foldable structural module may be characterized as being a C-shaped steel composed of a flange and a web.

[0018] In one embodiment, the frame fixing part of the foldable structural module may be characterized by being formed of aluminum material.

[0019] The installation method of a vertical photovoltaic power generation system provided in the present invention includes a folding structure expansion step of unfolding a folding structure, a lower fixing step of fixing the lower part of the folding structure using a lower folding fixing part, an upper folding fixing step of fixing the upper part of the folding structure using an upper folding fixing part, a photovoltaic module insertion step of inserting a photovoltaic module into a frame fixing part, and a cable connection step of connecting the cables of the photovoltaic modules to each other.

[0026] In one embodiment, the frame fixing part of the foldable structural module may be characterized by being formed of aluminum material.

[0027] Vertical photovoltaic systems maximize power generation efficiency while minimizing installation space by vertically arranging bifacial solar modules. This enables the efficient installation of solar power systems even on building facades or on narrow plots of land. Furthermore, the vertical module arrangement allows for the adjustment of the number of modules as needed, making it possible to construct solar power facilities of various sizes. This provides scalability that allows for flexible application depending on the installation environment and requirements.

Additionally, cables are housed within the C-shaped steel, providing efficiency during maintenance. The frame fixing section, crafted from aluminum, offers lightweight properties for easy assembly. At the same time, it possesses high durability, ensuring stable operation over extended periods. Fastening guides and anti-play protrusions simplify the assembly process and enhance structural reliability. This design results in reduced installation time and lower maintenance costs.

[0029] In addition, the lower and upper folding fixing parts firmly secure the folding structure, increasing resistance to external environmental factors (wind, vibration, etc.). In particular, the combination of anti-play protrusions and fastening guides prevents shaking of the solar modules, thereby reinforcing the stability of the entire system.

[0030] The flexible design of the foldable structural module allows it to adapt to various installation environments. Its vertical structure enables optimal installation even in confined spaces, such as building exteriors and narrow areas. Furthermore, it provides strong durability against external impacts and environmental changes. Meanwhile, bifacial solar modules increase power generation efficiency by simultaneously collecting light from both the front and the back. In particular, the ability to utilize reflected light from the rear enables higher power production compared to conventional monofacial systems.

Finally, the step-by-step assembly process according to the installation method will be described in detail technically, and the design advantages and implementation precautions for each stage will be covered.

[0046] Foldable structural module (100)

[0047] The foldable structure module (100) is a main support structure of the vertical photovoltaic power generation system (1000) and is a foundation structure that allows for the stable installation of the photovoltaic module (200). The folding structure part (110) has the characteristic of folding and unfolding, and increases space utilization during assembly and storage. The lower folding fixing part (120) firmly fixes the lower part of the folding structure part (110) and ensures the stability of the system.

Each detailed component is described.

[0048] The folding structure (110) is a core component of the foldable structure module (100) and can be folded or unfolded through an X-shaped cross structure. This structure utilizes a scissor mechanism to provide ease of installation and dismantling. When folded, the volume is minimized, making storage and transport easy, and when unfolded, it transforms into a stable structure. The folding structure (110) is connected to a frame fixing part (140) that extends in a vertical direction and supports the placement of the solar module (200).

[0049] The lower folding fixing part (120) serves to fix the lower part of the folding structure part (110) and ensures the basic stability of the system.

This design contributes to reducing installation time and improving structural stability. The frame fixing part (140) is a key component that increases the assembly and maintenance efficiency of the entire system. This will be explained in more detail later.

[0052] solar module (200)

[0053] FIG. 7 is a front view showing a vertical photovoltaic power generation system photovoltaic module according to one embodiment of the present invention.

[0054] Referring to FIG. 7, the solar module (200) is a core component of the vertical solar power generation system (1000) and is designed to enable bifacial power generation. This module consists of a base plate section (210), a solar cell string section (220), a junction box section (230), a cable (231), an electrode section (240), and a frame section (250). The front and rear surfaces of the module are symmetrically designed to efficiently collect light and maximize power generation efficiency. The cable and junction box support electrical connections safely and efficiently.

[0055] The base plate (210) is the basic structure of the solar module (200) and is composed of glass on both the front and back sides, serving to stably support the solar cell string (220). This component maintains the precise arrangement of the solar cells and can be strengthened to withstand external impacts or loads. To maximize the use of double-sided power generation characteristics, the front and back sides are designed in the same shape. The base plate (210) has an optimized size and shape so that it can be coupled to the frame fixing part (140).

[0056] The solar cell string section (220) is a major component responsible for power generation of the solar module (200). This string section is composed of multiple solar cells and is designed in a mixed manner of full string (221) and half string (222) for installation advantages. The string section is symmetrically arranged on the front and back sides to enable double-sided power generation, thereby increasing space efficiency and power generation efficiency. Each string is connected to a junction box section (230) to transmit the generated power.

[0057] The full string (221) is a component of the solar cell string section (220) and is configured to include a single continuous cell array along its entire length. This string provides high power density and is positioned at the top of the module to ensure maximum power generation efficiency. Electrical connections of the string are made through side electrodes (241).

[0058] The half string (222) is a component of the solar cell string section (220) and is designed to have a length less than half that of the linear string (221). Two of these strings are placed at the bottom of the module to produce power. The short length is adopted for a structure that can increase the coupling of the solar module. The half string (222) is connected to the center electrode (242) and is electrically connected to the junction box section (230).

[0059] The junction box section (230) is a key component that collects power generated from the solar cell string section (220) and transmits it to the outside. This box is located in the center and efficiently integrates power generated from the front and rear strings. It includes a bypass diode to minimize current flow obstruction and increase the reliability of the system. The junction box section (230) is connected to the central electrode (242) and transmits power to an external electrical system via a cable (231).

[0060] The cable (231) is responsible for the electrical connection between the junction box section (230) of the solar module (200) and the external system. The position of the cable is designed symmetrically so that it can be easily connected from the front and rear of the module. Although the present invention is illustrated with three solar modules (200) arranged, the number can be increased and arranged in both lateral directions to the required length based on this structure. This means that the length can be adjusted to suit the environment of each building by utilizing a simplified, repeating structure. Meanwhile, the cable (231) is housed inside the C-shaped steel of the upper folding fixing section (130), allowing for stable placement even after installation. This design provides both durability and ease of maintenance for the cable.

[0061] Frame part (250)

[0062] FIG. 8 is a cross-sectional view showing the frame portion of a vertical photovoltaic power generation system photovoltaic module according to one embodiment of the present invention.

[0063] Referring to FIG. 8, the frame portion (250) provides structural support for the solar module (200) and supports the installation of the module by combining with the frame fixing portion (140). This component consists of a frame body (251), a gap prevention projection (252), and a fastening guide (253). The frame portion is made of aluminum, providing both lightness and durability. It ensures stability during module assembly and increases efficiency during the installation process. This design can simplify the assembly and maintenance of the solar power generation system.

[0064] The frame body (251) is a central structure of the frame section (250) and serves to support the solar module (200). The frame body (251) is a basic configuration including a fastening guide (253) and a gap prevention projection (252).

[0065] The anti-slip protrusion (252) is a component designed to prevent shaking and enhance structural stability after assembly of the solar module (200). This protrusion is integrated into the frame portion (250) and is designed to ensure that the module is firmly fixed during the fastening process. The size and position of the protrusion are in harmony with the module's fastening guide (253) to provide optimal assembly results. The anti-slip protrusion (252) provides additional stability during the assembly process and supports a long lifespan for the module. Although there is a possibility that the vertically positioned solar module (200) may shake due to external wind or the like, this structure allows for maintaining a more stable structure.

[0066] The fastening guide (253) is a component that supports accurate fastening between the solar module (200) and the frame fixing part (140). This guide clarifies the fastening direction during the module insertion step (S400), thereby increasing assembly efficiency. The fastening guide is combined with the anti-play projection (252) to prevent shaking of the installed module.

[0067] Installation method of a vertical photovoltaic power generation system

[0068] Referring again to FIGS. 1 to 6b, a method for installing a power generation system is described. The method for installing a power generation system defines a procedure for the stable installation of a vertical photovoltaic power generation system (1000). This method consists of a folding structure expansion step (S100), a lower fixing part fixing step (S200), an upper folding fixing part fixing step (S300), a photovoltaic module insertion step (S400), and a cable connection step (S500). This installation method provides a basis for achieving optimal performance even under various environmental conditions.

[0069] Referring to FIGS. 1 and 2, the folding structure expansion step (S100) is an initial process of unfolding the folding structure (110) of the folding structure module (100) to complete the preparation for installation. In this step, the folding structure (110) is stably expanded using an X-shaped cross structure. The expansion process is performed by simple mechanical movements, which shortens installation time and increases work efficiency. The expanded folding structure (110) maintains a vertical structure and is ready to be combined with lower and upper fixing parts in a subsequent step. This step forms the foundation of the installation process and ensures the stability and balance of the entire system. In this step, the area of ​​solar modules (200) that can be installed over the entire area can be adjusted by controlling the required number of folding structure modules (100).

[0070] Referring to FIG. 3, the lower fixing fixing step (S200) is a process of fixing the lower part of the folding structure (110) to the lower folding fixing part (120). In this step, a lower fixing support is used to fix the structure to the ground. The lower folding fixing part (120) firmly supports the lower part of the folding structure and provides structural stability against external loads and vibrations. This fixing step secures basic structural stability and serves to fix the entire system in an environment where the system may be shaken by wind, etc.

[0071] Referring to FIG. 4, the upper folding fixing part fixing step (S300) is a process of fixing the upper part of the folding structure part (110) to the upper folding fixing part (130). In this step, the upper folding fixing part (130) utilizes a C-shaped steel member composed of a flange and a web to achieve a stable connection. The upper fixing process enhances the overall structural completeness of the folding structure part and enables the safe storage of the cable (231). The fixed upper folding fixing part (130) provides resistance to external impact and wind pressure, and completes the preparation state for the installation of the solar module. This step is an important process that ensures the final stability and durability of the system.

[0072] Solar module insertion step (S400)

[0073] The solar module insertion step (S400) is a process of installing a solar module (200) by attaching it to a frame fixing part (140). In this step, the solar module is accurately inserted along the fastening guide (253) of the frame fixing part. The inserted module is fixed without shaking by the anti-slip projection (252) and maintains structural stability in the installed position. Module insertion is performed as a quick and simple operation, allowing all modules to be systematically aligned. This step completes the foundational work for the electrical connection of the solar power generation system and maximizes the efficiency of the entire assembly process.

[0074] Cable connection step (S500)

[0075] The cable connection step (S500) is a process of completing the electrical system by connecting cables (231) extended from the junction box section (230) of the solar module (200). The connected cables are housed inside the C-shaped steel of the upper folding fixing section (130) and protected from the external environment. The cable connection is performed using high-quality insulating material to minimize electrical resistance and ensure stable power transmission. This step supports the smooth transmission of generated power to an external system and verifies electrical stability through system inspection after installation is complete. The cable connection step is the final completion stage of power production and transmission in the system.

[0076] The embodiments of the invention described above are not mutually exclusive or distinct. The respective configurations or functions of the embodiments of the invention described above may be used in combination or combination. It is obvious to those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit and essential features of the invention.
