Description

TECHNICAL FIELD

[0001] The present invention relates to tracking devices for solar modules and their systems. More specifically, the present invention relates to a non-electrical system for adjusting the position of solar modules using a shape memory alloy to efficiently track the movement of the sun. BACKGROUND

[0002] Conventional solar module tracking systems primarily use electrical energy to track the sun's movement. Electrically powered, motorized systems consume a large portion of the electrical energy generated by the solar modules. This reduces the overall efficiency due to excessive energy consumption in the field. The static position of solar modules can enable a minimal energy conversion rate due to their absorption capacity through this special positioning. To date, no systems for tracking the sun's movement have been implemented without the use of electrical components. Therefore, there is a need for a system for tracking the movement of solar modules without the use of electrical components. The present invention effectively overcomes the above-mentioned problems, limitations, and disadvantages. OBJECT OF THE INVENTION

[0003] The main objective of the present invention is to provide a non-electrical solar module tracking system for tracking the sun's movement without the use of electrical components.

[0004] Another aim of the present invention is to reduce energy waste in tracking solar modules.

[0005] Another object of the present invention is to provide a mechanical system for adjusting the position of the solar modules in order to effectively track the sun's movement in multiple directions.

[0006] Another object of the present invention is to introduce a non-electrical tracking system at an affordable price and highest quality.

[0007] These and other objects and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings. SUMMARY

[0008] The various embodiments of the present invention provide a non-electrical system for adjusting the position of solar modules using a shape memory alloy to track sunlight in multiple directions. The non-electrical system consists of a base, a ball joint, multiple shape memory alloys, multiple aluminum plates, and multiple counterweights. The module base is configured to allow the solar module to be removably mounted above the ground to capture sunlight and convert it into electrical energy. The ball joint is located on the underside of the module base and allows the module to move in multiple directions to effectively capture sunlight.

[0009] At the corners of the solar module are several Nitinol shape-memory alloys. These shape-memory alloys contract or expand with solar-induced temperature changes. The movement of the shape-memory alloy changes the position of the module through the ball-and-socket joint movement. Depending on the thermal and counterweight load, the shape-memory alloy can be both vertically compressed and stretched to follow the sunlight in multiple directions.

[0010] The multiple aluminum plates surround the shape memory alloy and absorb the heat from sunlight, transferring it to the shape memory alloy and thus triggering the deformation. The aluminum plate and the SMA are coated with a thermal insulation layer to regulate heat transfer and prevent overheating. The aluminum plate is additionally coated with a ceramic coating to increase its resistance to adverse environmental conditions.

[0011] The aluminum plate also houses a heat distribution system for evenly distributing heat across the shape memory alloy. The multiple counterweights positioned with the shape memory alloy strips compensate for the movement of the solar module by harnessing the alloy's deformation caused by the heat generated by sunlight. The counterweight, SMA, and aluminum plate can be positioned at any corner of the module base to track sunlight in multiple directions.

[0012] These and other aspects of the embodiments described herein will become more fully understood in conjunction with the following description and the accompanying drawings. The following descriptions, while showing preferred embodiments and numerous specific details thereof, are illustrative and not limiting. Numerous changes and modifications are possible within the scope of the embodiments described herein without departing from the spirit thereof, and the embodiments described herein are intended to include all such modifications.

[0015] The various embodiments, as well as further developments and features, are explained in the following detailed description using non-limiting details. The depiction of processing techniques for known components is omitted in order not to unnecessarily obscure the embodiments described herein. The examples used herein are intended to facilitate understanding of the possible applications of the embodiments described herein and to enable those skilled in the art to implement the embodiments described herein. The examples are therefore not to be understood as limiting the scope of application of the embodiments described herein.

[0016] The various embodiments of the present invention comprise a non-electrical system (10) for adjusting the position of solar modules using the shape memory alloy NITINOL. The non-electrical system consists of a base, a ball joint, several shape memory alloys, several aluminum plates, and several counterweights. The module base (16) is configured so that the solar module is removably mounted above the base surface to capture sunlight and convert it into electrical energy. The ball joint (12) is located on the underside of the module base.

[0017] The ball joint allows the panel to move in multiple directions to effectively capture sunlight. At each corner of the solar panel are multiple Nitinol shape-memory alloys (13). These shape-memory alloys contract or expand with solar-induced temperature changes. The movement of the shape-memory alloy changes the position of the panel through the ball joint movement. The shape-memory alloy (13) is both compressible and vertically expandable depending on thermal and counterweight loads to follow the sunlight in multiple directions.

[0018] Fig. shows a schematic representation of the non-electrical system for adjusting the position of the solar panel assembly according to an embodiment of the present invention. The plurality of aluminum plates (14) surround the shape memory alloy and absorb the heat from sunlight, transferring it to the shape memory alloy, and thus initiating deformation. The aluminum plate and the SMA are provided with a thermal barrier layer to regulate heat transfer and prevent overheating. The aluminum plate (14) is also provided with a ceramic coating to increase resistance to adverse environmental conditions. The aluminum plate also houses a heat distribution system for evenly distributing heat to the shape memory alloy.

[0019] The multiple counterweights (15) are positioned with the shape memory alloy strips to compensate for the movement of the solar module caused by the alloy's deformation due to heat generated by sunlight. The counterweight, SMA, and aluminum plate can be positioned at any corner of the module base to track sunlight in multiple directions.

[0020] The present invention (10) is a non-electrical solar tracker that enables solar modules to automatically track the sun. The present invention uses nitinol shape memory alloys (SMAs) with corrosion-resistant and thermally insulating coatings for improved durability and thermal responsiveness. The aluminum plates (14) enhance heat transfer, counterweights provide stability, and a ball-point mechanism enables smooth, multidirectional movement. The system operates without electricity and is therefore cost-effective, low-maintenance, and ideal for remote areas. This innovative, environmentally friendly solution maximizes solar energy efficiency in a sustainable manner.

[0021] Solar panel (11): The main component that captures sunlight and converts it into electrical energy. The solar panel is mounted on a ball joint to allow movement in all directions, ensuring maximum sunlight exposure throughout the day.

[0022] Ball joint: The flexible joint (12) in the center of the system allows the solar module to be freely tilted and rotated. This allows the solar module to efficiently follow the movement of the sun across the sky.

[0023] SMA (Nitinol): The shape memory alloy (13) is located at the four corners of the solar module. These SMA strips contract or expand with temperature changes caused by sunlight. Their movement determines the tilt and positioning of the solar module.

[0024] Aluminum plate (14): Surrounds the SMA components to absorb sunlight heat and transfer it to the SMA. The plate ensures efficient heat transfer, causing the SMA to deform and adjust the module's position.

[0025] Counterweight: Weights (15) attached to the SMA strips balance the solar module's movements. These counterweights ensure smooth and stable operation and compensate for the forces caused by the contraction or expansion of the SMA.

[0026] Solar module base (16): The rigid and stable platform that supports the entire system. It anchors the ball joint and other components and ensures that the solar module remains securely in place during operation.

[0027] Thermal insulation layer: The protective layer on the SMA and the aluminum plates regulates heat transfer and prevents overheating. This coating ensures that the SMA operates within the optimal temperature range, improving system efficiency and durability.

[0028] Ceramic coating: This additional protective layer on the SMA increases its wear and corrosion resistance. It extends the durability and service life of SMA components in outdoor applications.

[0029] Support columns: The vertical structures that lift the solar panel system and provide structural stability. These columns hold the base and ensure the safe operation of the system.

[0030] Heat distribution system (17): This non-electrical subsystem is integrated into the aluminum plates and distributes heat evenly across the SMA. This ensures uniform deformation of the SMA.

[0031] The solar module can be removably positioned on the module base. The module base is positioned above the ball joint. The ball joint (12) allows the base to move in multiple directions. The tracking system consists of at least four shape memory alloys, aluminum plates, and counterweights. The four numbers can be attached to any corner of the module base. The shape memory alloy (13) automatically deforms depending on the temperature. The aluminum plate (14) regulates the heat transfer from sunlight to the shape memory alloy. During the deformation of the SMA, the counterweights contribute to changing the position of the module through their weight factor.

[0032] Fig. Shows the position of the solar module tracking system in the morning according to an embodiment of the present invention. In the morning, SMAs 1 and 2 are oriented vertically to the east. The heat contact with the SMA / aluminum plate contributes to deformation through changes in its properties. The counterweight (15) then acts to the east. The module is accordingly oriented to the east.

[0033] Fig. Shows the position of the solar module tracking system in the afternoon according to an embodiment of the present invention. In the afternoon, heat is distributed evenly to all SMAs due to solar radiation. Uniform deformation occurs in the afternoon. At this time, no counterweight acts in a specific direction.

[0034] Fig. shows the position of the solar module tracking system in the evening according to an embodiment of the present invention. In the evening, SMAs 3 and 4 are oriented vertically to the west. Heat contact with the SMA / aluminum plate contributes to deforming the shape through changes in properties. The counterweight then acts to the west. The panel is also oriented to the west.

[0035] Fig. shows the position of the solar panel tracking system at night according to an embodiment of the present invention. At night, no heat is dissipated to the SMAs. Therefore, the SMA (13) remains in its original position.

[0036] The examples of the present invention described above are for illustrative purposes only. Although the present invention has been described using a specific example, numerous modifications are possible without materially departing from the teachings and advantages of the subject matter described herein. Further substitutions, modifications, and changes are possible without departing from the spirit of the present solution. All of the features and / or steps of the methods or processes described herein (including the appended claims, abstract, and drawings) and / or all of the steps of the methods or processes described therein may be combined in any way, except for combinations in which at least some of these features and / or steps are mutually exclusive.Although the embodiments described herein are described in terms of various specific embodiments, it will be obvious to those skilled in the art to practice the embodiments described herein with modifications.
