Description:FIELD OF THE INVENTION

[0001] The present invention relates to a solar panel management device is capable of optimizing solar energy harvesting by dynamically tracking the sun's position and maintaining the cleanliness of the solar panel surface by deterring birds.

BACKGROUND OF THE INVENTION

[0002] The increasing global demand for renewable energy sources has driven significant advancements in solar power technology. Solar panels, while highly effective at converting sunlight into electricity, face inherent challenges that limit their overall efficiency and long-term performance. A primary concern is the dynamic nature of the sun's position throughout the day and across seasons, which means fixed solar panels rarely receive sunlight at the optimal perpendicular angle, leading to reduced energy harvest. Furthermore, environmental factors, particularly the accumulation of debris such as dust, leaves, and critically, bird droppings, significantly obstruct the panel's surface, diminishing its ability to absorb solar radiation and thereby decreasing power output and requiring frequent, often manual, cleaning.

[0003] Traditionally, efforts to mitigate these issues have involved separate and often incomplete solutions. Sun-tracking systems, ranging from simple seasonal adjustments to complex dual-axis trackers, have been employed to improve incidence angles, but these often add significant mechanical complexity, cost, and maintenance requirements. Similarly, panel cleaning has relied on manual labor, robotic cleaning systems, or natural rainfall, none of which provide a proactive or continuous solution against specific nuisances like bird droppings. There remains a need for an integrated, efficient, and automated solution that not only ensures optimal sun tracking for maximum energy capture but also actively prevents the accumulation of efficiency-degrading foreign matter, thereby enhancing the reliability and output of solar energy systems.

[0004] US9521838B2 discloses about an invention of a photovoltaic cell or array is used to power a bird repelling device that emits deterrent sounds from a speaker or other sound emitter, under control of an electronic processor. Repellent sounds can be either a single sound, or a set of sounds, including for example pest species sounds and predator species sounds. One or more sensors, and a user interface, can assist in controlling which sound(s) to use, and when.

[0005] US8459249B2 discloses about an invention of a solar tracking system with a torque tube supporting solar panels. Columns support the system and have bearings for rotation of the torque tube. A drive is coupled to the torque tube and is driven by a gearbox, such as a worm gear assembly, for rotating the array of solar panels to follow the sun's diurnal motion. The array can rotate in an opposite direction, or backtrack, to prevent shadowing from one module row to another. Multiple gearboxes can be mechanically linked by drive shafts and driven by a single motor. The drive shafts may incorporate universal joints for uneven terrain or staggered configurations. Harmonic dampers can be affixed to the solar panels to decouple wind forces which allows the use of larger solar panels.

[0006] Conventionally, many devices are disclosed that attempt to optimize solar energy harvesting or manage solar panel maintenance. However, such conventional devices often suffer from significant limitations. For instance, many existing solar panel installations are static, meaning they are fixed in one position and cannot adjust to the sun's changing angle throughout the day or across seasons. This significantly reduces their efficiency, as sunlight rarely strikes the panel at the optimal perpendicular angle for maximum energy conversion.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop an automated solution for solar panel management. The solution should not only dynamically track the sun to ensure optimal angle of incidence for maximum energy harvesting but also proactively prevent the accumulation of efficiency-reducing debris, particularly bird droppings, without requiring constant manual intervention or complex reactive cleaning systems. Such a device would significantly enhance the overall efficiency, reliability, and lifespan of solar power installations, thereby maximizing the return on investment for users and contributing more effectively to renewable energy goals.

OBJECTS OF THE INVENTION

[0008] The principal object of the present invention is to overcome the disadvantages of the prior art.

[0009] An object of the present invention is that the invention maximizes the efficiency of solar energy harvesting by continuously orienting the solar panel to receive sunlight at an optimal perpendicular angle, thereby overcoming the limitations of static or inefficiently tracked solar installations.

[0010] Another object of the present invention is to provide a device that proactively prevents the accumulation of bird droppings on the surface of the solar panel, thus maintaining its maximum energy absorption capability and reducing the need for manual cleaning and associated maintenance costs.

[0011] Yet another object of the present invention is to provide an integrated and automated solution for solar panel management that combines precise sun-tracking with active bird deterrence, offering a comprehensive system that enhances both energy yield and operational reliability with minimal user intervention.

[0020] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0021] The present invention relates to a solar panel management device that is capable of optimizing solar energy harvesting by dynamically tracking the sun's position and maintaining the cleanliness of the solar panel surface by deterring birds.

[0022] Referring to Figure 1, an isometric view of a solar panel management device is illustrated, comprising a shaft 101 installed on a fixed surface by means of a pair of links 102, a bearing arrangement 103 integrated between the shaft 101 and top of each of the link 102 to allow the shaft 101 to rotate freely, a V-shaped frame 104 arranged on each ends of the shaft 101, a sensing module 105 installed on the top of one of the frame 104, an ultrasonic emitter 106 is mounted on each of the frame 104.

[0023] The device disclosed herein includes a shaft 101 that is installed on a fixed surface by means of a pair of links 102. The shaft 101 serves as the central rotational axis for solar panels, designed for free and efficient movement. The shaft 101 structurally is a cylindrical bar, typically made of a rigid and durable material like steel and aluminum, capable of withstanding the loads imposed by the solar panel and its associated component.

[0024] The pair of links 102 primarily function as a fixed structural support for the shaft 101, rather than having complex internal arrangement themselves. These links 102 are robust, rigid components, fabricated from a strong and durable material such as steel and aluminium. They are designed to be securely installed on a stationary, fixed surface, forming a stable base for the entire solar panel device.

[0025] A user activates the device for further operation, which is done by a simple pressing of a push button installed on the shaft 101. The push button is typically made from polycarbonate. When push button is pressed by a user to switch on the device it allows current to flow. This sends a signal to the device's microcontroller, instructing it to activate the device. The microcontroller then powers up the device, enabling them to function.

[0026] Once the device powers up, the microcontroller activates a bearing arrangement 103 installed between the shaft 101 and top of each of the links 102 to allow the shaft 101 to rotate freely. The bearing arrangement 103 facilitates the shaft's 101 free rotation by internally utilizing precision components, typically including an inner ring, an outer ring, and rollers, often separated by a cage. The outer ring is fixed within the links 102, while the inner ring is securely mounted on the shaft 101. As the shaft 101 rotates, the rolling elements roll along precisely ground raceways on both rings, effectively converting sliding friction into much lower rolling friction. The rolling action, aided by internal lubrication (grease or oil), minimizes resistance, heat generation, and wear, ensuring smooth, efficient, and durable rotation of the shaft 101 and, consequently, the solar panel.

[0027] A V-shaped frame 104 arranged on each end of the shaft 101, that are accessed by the user to install the solar panel for harvesting electricity from solar radiation. The frame 104 primarily functions as the rigid structural element onto which the solar panel is securely mounted. The frame’s 104 V-shape is engineered not only for structural integrity and ease of user installation but also to potentially optimize the angle at which the solar panel is presented for sunlight capture.

[0028] In order to monitor angle of incidence of sunlight, sunlight intensity, and to track sun, a sensing module 105 mounted on the top of one of the frame 104 is used. The sensing module 105 works internally through the coordinated operation of its component that are a Light Dependent Resistor (LDR) which provides data of light intensity and a Position Sensitive Detectors (PSD) which precise angular information.

[0029] The LDR operates on the principle of photoconductivity. Internally, it consists of a photosensitive semiconductor material, often cadmium sulfide (CdS), arranged in a zigzag pattern to maximize surface area. When photons of light strike this material, they impart energy to electrons, causing them to jump from the valence band to the conduction band. This increase in free charge carriers (electrons and holes) within the material directly leads to a decrease in the LDR's electrical resistance. Conversely, in the absence of light, fewer electrons are excited, and the resistance increases significantly. Thus, by measuring the resistance across the LDR, the module internally determine the intensity of the incident sunlight.

[0030] The PSD is a semiconductor photodiode, works on the principle of the lateral photo effect. When a focused spot of light from the sun hits its active surface, the detector then generates photocurrents. The PSD has multiple electrodes-two for one-dimensional sensing, or four for two-dimensional sensing. The distribution of these photocurrents among the electrodes depends on the precise location of the light spot on the detector's surface. For example, if the light spot is closer to one electrode, a larger current will be collected by that electrode. Internal circuitry within the PSD, or an external analog-to-digital converter (ADC) and processing unit, measures these current differences and ratios. The PSD then calculates the exact X-Y coordinates of the light spot on its surface. This position information is directly correlated with the angle of incidence of the sunlight.

[0031] Based on this real-time input, the microcontroller compares the sensed sunlight angle with the ideal perpendicular angle (0 degrees) for maximum energy absorption. If a deviation is detected, the microcontroller calculates the precise direction and magnitude of rotation required to reorient the solar panel, then the microcontroller generates specific electrical signals that are sent to a motor driver The motor driver, in turn, amplifies these signals to provide the necessary voltage and current to actuate the direct current (DC) motor. The DC motor, being mechanically coupled with the shaft 101, then rotates the shaft 101 and the attached V-shaped frames 104 and solar panel. The rotational movement continues under the microcontroller's command until the sensing module reports that the sunlight is incident perpendicularly on the panel, indicating optimal alignment for maximum solar energy harvesting. The entire process is dynamic and continuous, allowing the device to actively track the sun's movement throughout the day, ensuring consistent and efficient energy capture.

[0032] Additionally, a passive infrared (PIR) sensor installed on top of each of frame 102, to detect presence of birds on the solar panel. The passive infrared sensor functions internally by detecting changes in the infrared radiation (heat) emitted by objects in its field of view, specifically for the purpose of identifying the presence of birds. At its core, a PIR sensor typically comprises two pyroelectric elements, which are special materials that generate an electrical charge when exposed to infrared radiation. These two elements are usually arranged in a balanced, differential configuration. When the sensor is idle, both elements detect a uniform amount of ambient infrared radiation from the surroundings.

[0033] In case of detection of presence of birds on the solar panel, the microcontroller activates an ultrasonic emitter 106 integrated on each of the frame 102 to deter the birds to prevent accumulation of bird droppings on the solar panel, to ensure maximum energy is absorbed by the solar panel. The ultrasonic emitter 106 operates by converting an electrical signal from the microcontroller into high-frequency sound waves, beyond human hearing. At its core is a piezoelectric transducer, containing a piezoelectric material (often ceramic). When an alternating electrical voltage is applied, the material rapidly expands and contracts due to the inverse piezoelectric effect. The frequency of these vibrations matches the electrical signal, specifically set in the ultrasonic range (e.g., 20 kHz or higher). These rapid vibrations generate pressure waves in the air, propagating as ultrasonic sound. The emitter's design includes acoustic layers to efficiently direct these sound waves. The swift generation of ultrasonic sounds, irritating and discomforting to birds, and preventing them from accumulating droppings on the solar panel.

[0034] Lastly, a battery (not shown in figure) is associated with the device to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrode named as a cathode and an anode. The battery uses a chemical reaction of oxidation/reduction to do work on charge and produce a voltage between their anode and cathode and thus produces electrical energy that is used to do work in the device.

[0035] The present invention works best in the following manner, where the shaft 101 is installed on a fixed surface by means of a pair of links 102, with a bearing arrangement 103 between the shaft 101 and each link top 102, allowing the shaft to rotate freely. Upon activation, the V-shaped frames 105 are installed on each end of the shaft 101, providing a structure for the user to mount a solar panel for harvesting electricity from solar radiation. During operation, a sensing module 105, which includes components such as but not limited to the Light Dependent Resistor and the Position Sensitive Detectors, is installed on the top of one of the frames 102, these sensors continuously monitors the angle of incidence of sunlight and its intensity, and tracks the sun's direction. Subsequently, an inbuilt microcontroller, linked with the sensing module 105, receives this data and actuates a direct current motor, which is precisely coupled with the shaft 101. This action causes the shaft 101 to rotate the frames 102 along with the mounted solar panel, based on the sun's direction, thereby ensuring sunlight always incidents perpendicularly on the panel to harvest maximum solar energy. Concurrently, a passive infrared sensor installed on top of each frame 102 actively detects the presence of birds on or near the panel. In case of bird detection, the microcontroller activates an ultrasonic emitter 106, also installed on each frame 102, to deter the birds. The deterrence prevents the accumulation of bird droppings on the solar panel, which in turn ensures maximum energy absorption.
