Description

Technical Field

[0001] The present invention relates to the technical field of solar energy, and particularly to a solar energy device for buildings and its usage method. Background Art

[0002] A solar energy device is a device that converts solar energy into electrical energy. It converts solar light energy into direct current through the photovoltaic effect, providing clean and renewable energy for buildings. Such solar energy devices are usually installed on parts such as the roofs of buildings, which can not only effectively utilize the building space, reduce the dependence on traditional energy sources, but also have the advantages of environmental protection and energy conservation, helping buildings achieve green and sustainable development.

[0003] In a Chinese patent with the patent publication number CN109361351A, a solar panel cleaning device with good dust removal effect is disclosed, including a support plate, a fixed rod, a base, a water storage tank and two fixed boxes, and also including a cleaning mechanism and a collection mechanism. The cleaning mechanism includes a cleaning box, a water spraying assembly and two moving assemblies. The water spraying assembly includes a driving unit, a connecting rod and two water spraying units. The water spraying unit includes a support shaft, a nozzle and a hose. The collection mechanism includes a collection box, an impurity removal assembly and a water pumping assembly. The impurity removal assembly includes a first motor, a rotating rod and a brush. This solar panel cleaning device with good dust removal effect can, through the cleaning mechanism, clean the solar panel to avoid dust covering the solar panel and affecting the power generation effect. Through the collection mechanism, the sewage can be filtered and reused, reducing the cleaning cost and improving the environmental protection of the device.

[0004] However, the device and the prior art in the cited document still have the following defects in specific use:

[0005] 1. In the cited document, the solar panel is cleaned by making two nozzles swing and spray water, and at the same time, the collected sewage is filtered and reused. However, in the actual use environment, since the solar panel is usually set on the roof position, its environment is relatively complex and easily affected by external factors. When cleaning with water, although it can wash away some surface dust and dirt, for those dust particles that have a certain adhesion to the surface of the solar panel, the washing force of water is difficult to completely remove them. These remaining dust and impurities will gradually gather together during the flowing and evaporation process of the water, forming obvious traces.

[0006] First of all, these traces will hinder the absorption and conversion of sunlight. The cleanliness of the solar panel surface directly affects the light energy absorption efficiency. The traces formed by dust and impurities will block part of the sunlight, reducing the effective light receiving area of the solar panel, thereby reducing the power generation efficiency.

[0007] Secondly, once these traces are formed after air drying, subsequent cleaning will become more difficult. Dust and impurities in the air-dried traces will adhere more firmly to the surface of the solar panel, and the surface tension of water and the flushing force are difficult to disperse them again. This means that stronger cleaning means, such as high-pressure water guns, chemical cleaners, etc., need to be used, but these methods will damage the surface of the solar panel, and at the same time increase the cleaning cost and maintenance difficulty.

[0008] 2. During actual use, solar panels are usually installed above the tiles with the help of guide rails. However, in humid weather conditions, the close distance between the bottom of the solar panel and the tiles will cause serious moisture accumulation problems between the two. Long-term exposure to a high-humidity environment will accelerate the aging process of the tiles. When the tiles reach a certain degree of aging, their waterproof performance will be damaged, and rainwater will penetrate into the roof structure, causing roof leakage problems. For solar panels, moisture is likely to penetrate into the internal structure of the solar panel and damage its electronic components.

[0009] At the same time, in hot weather conditions, the close distance between the bottom of the solar panel and the tiles will cause problems of difficult heat dissipation. During the process of absorbing solar energy and converting it into electrical energy, the solar panel will generate a large amount of heat. Due to the close distance between its bottom and the tiles, the heat cannot be dissipated in time and effectively, causing the temperature of the solar panel to rise rapidly. Research shows that when the temperature of the solar panel rises by 1°C, its power generation efficiency will decrease by about 0.4% - 0.5%. This is because high temperature will reduce the electron mobility of the semiconductor material inside the solar panel, thus affecting the photoelectric conversion efficiency. In the hot summer, the temperature of the solar panel may rise by dozens of degrees Celsius, which will lead to a significant decrease in its power generation efficiency and affect the overall performance of the solar power generation system.

[0010] Therefore, the present invention proposes a solar device for buildings and its usage method. Summary of the Invention

[0011] The purpose of the present invention is to provide a solar device for buildings and its usage method to solve the problems raised in the above background technology.

[0012] To achieve the above object, the present invention provides the following technical solution: A solar device for buildings, comprising a plurality of guide rails, on top of which a solar panel is installed. A bionic cleaning assembly is arranged outside the guide rails. The bionic cleaning assembly includes two trapezoidal seats, which are respectively fixedly connected to the outside of the outermost guide rail. The trapezoidal seats are all provided with empty slots through their surfaces. Two annular protrusions extend outwards on the outer surfaces of the trapezoidal seats. A reciprocating lead screw is rotatably connected inside the annular protrusions. A driving member is installed outside the guide rail, and the output shaft of the driving member is fixedly connected to the reciprocating lead screw. Sliders are slidably connected to the outer surfaces of the trapezoidal seats. A cylindrical protrusion is arranged outside the sliders, and the cylindrical protrusion is slidably connected to the outer surface of the reciprocating lead screw. A chute is provided in the middle of each slider, and a limiting post is slidably connected inside the chute. The limiting post is also slidably connected inside the empty slot. A pull-and-push piece is fixedly connected to the side of the limiting post away from the reciprocating lead screw. A cleaning roller is rotatably connected between every two pull-and-push pieces. A water replenishing tank is installed outside the guide rail and on the side close to the driving member, and a water draining tank is installed outside the guide rail and on the side away from the water replenishing tank.

[0013] Preferably, a solenoid valve and a position sensor 1 are installed at the bottom of the water replenishing tank. A snap-on cover is installed on top of the water replenishing tank. A circulation module is installed outside the water replenishing tank, which is used to provide the function of liquid circulation. A sequencer and a position sensor 2 are installed outside the water replenishing tank.

[0014] Preferably, the inside of the water draining tank is in a gradually shrinking shape, and a plurality of water draining holes are provided at the bottom of the water draining tank.

[0015] Preferably, the empty slot is trapezoidal, and a water-absorbing material is sleeved on the outer surface of the cleaning roller.

[0016] Preferably, a driving module is installed outside the snap-on cover, which is used to provide an automatic opening and closing function for the snap-on cover.

[0017] Preferably, a confluence and air-drying assembly is provided at the bottom of the water replenishing tank and the water draining tank. The confluence and air-drying assembly includes a plurality of hollow vertical beams, which are linearly and equidistantly arranged and installed at the bottom of the water replenishing tank and the water draining tank. Two rows of limiting rings are linearly and equidistantly arranged and installed inside each hollow vertical beam. A limiting shaft is rotatably connected inside each limiting ring. A first confluence piece and a second confluence piece are respectively installed on the outer surfaces of a plurality of the limiting shafts.

[0018] Preferably, the limiting shaft is circular, but a rectangular protrusion is provided on its outside. The inside of the limiting ring is circular, but the side close to the inner wall of the hollow vertical beam expands outwards.

[0019] Preferably, the first bus bar and the second bus bar are arranged in an alternating manner on the outer surface of the limiting shaft. Both the first bus bar and the second bus bar are made of a plastic material, specifically polyethylene.

[0020] Preferably, the liquid provided by the circulation module is water.

[0021] A method for using solar energy in buildings includes the following steps:

[0022] Step 1: Check whether the connections between the solar panels and the controller are firm, whether the wires are damaged or short-circuited, confirm whether the grounding protection of the system is good, and at the same time check whether there is dust, stains, or obstructions on the surface of the solar panels. If so, clean them in time to ensure the lighting effect of the solar panels.

[0023] Step 2: Start the system to make it start working.

[0024] Step 3: Monitor the operating status of the system. Observe the power generation power, voltage, and current parameters of the solar panels through the display screen on the controller.

[0025] Step 4: Connect the electrical appliance to the output port of the system, and then the electricity generated by the solar panels can be used. Note that the power of the electrical appliance should be within the carrying capacity of the system to avoid overloading.

[0026] Step 5: Perform regular maintenance. Regularly check the surface cleanliness of the solar panels, remove dust, leaves, and debris, and keep the surface of the solar panels clean.

[0027] In the fourth step, the carrying capacity of the system is within 360W.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] 1. By driving the reciprocating lead screw to rotate through the driving member, the cleaning roller is driven to reciprocate on the surface of the solar panel, thereby realizing the cleaning of the surface of the solar panel. Inside the water replenishing tank, the cleaning roller absorbs water to keep its surface wet, so as to better adsorb and clean the dust and dirt on the surface of the solar panel. When the cleaning roller moves into the water draining tank, since the inside of the water draining tank presents a gradually shrinking shape, during the movement, the inner wall of the water draining tank squeezes out the water on the surface of the cleaning roller to achieve wet-dry separation. Subsequently, during the reset process of the cleaning roller, it will clean the surface of the solar panel again in a relatively dry state, effectively avoiding the formation of dust and impurity traces caused by water residue, ensuring that the surface of the solar panel always remains clean, and improving the light energy absorption efficiency.

[0030] Among them: During the cleaning process of traditional solar panels, the cleaning tools are prone to mildew when they are wet for a long time, which affects their service life and cleaning effect. In the present invention, during the reset process of the cleaning roller after water drainage, the sequencer will control the cleaning roller to stop at the water replenishing tank until it no longer contains moisture, thereby realizing the drying treatment of the cleaning roller. This design effectively prevents the cleaning roller from mildewing due to long-term moisture, ensures the cleaning performance and service life of the cleaning roller, and provides guarantee for the long-term stable cleaning of solar panels.

[0031] Among them: Traditional cleaning methods for solar panels often fail to achieve ideal cleaning effects, while the cleaning method of the present invention is similar to the effect of manual wiping, that is, bionic cleaning. Through the reciprocating movement of the cleaning roller and the dry-wet separation design, it can get closer to the surface of the solar panel, and clean dust and dirt meticulously. Just like manually wiping with a clean cloth, it can not only remove surface dust, but also effectively remove some impurities with strong adhesion, greatly improving the cleaning quality and efficiency, and keeping the solar panel in good working condition all the time.

[0032] Among them: In practical applications, solar panels need to fully absorb light energy during the day for power generation. If traditional cleaning methods are carried out during the day, they will block the solar panels and affect their light energy absorption efficiency. The present invention controls the bionic cleaning component to operate after the sun sets through the sequencer. At this time, the solar panel no longer conducts power generation work, and the cleaning process will not have any impact on the light energy absorption of the solar panel. This intelligent sequencer control design fully considers the working characteristics of the solar panel, and while ensuring the cleaning effect, maximally improves the power generation efficiency of the solar panel.

[0033] Among them: In a complex outdoor environment, solar panels are easily affected and damaged by external factors. The trapezoidal seat design in the present invention not only provides a stable support and installation foundation for components such as the reciprocating lead screw and slider, but also can protect the solar panel to a certain extent. The trapezoidal seat can block the impact of some external objects on the edge of the solar panel, reduce the risk of damage to the solar panel, extend its service life, and provide strong guarantee for the safe operation of the solar panel.

[0034] 2. When the wind flows between the hollow vertical beam and the tiles, it will blow the first current collector and the second current collector, forming a main flow and a split flow, and the two continuously converge, thereby accelerating the air flow speed. In this way, it can effectively dry the space between the bottom of the solar panel and the tiles, avoid moisture accumulation, prevent the aging of the tiles and the occurrence of roof leakage problems. At the same time, it can also timely take away the heat generated by the solar panel, reduce its temperature, avoid the decline of power generation efficiency caused by high temperature, and ensure that the solar panel can work stably and efficiently under various weather conditions.

[0035] Among them: Traditional ventilation designs often require complex structures and numerous driving components to achieve air circulation. In this invention, due to the design of the limiting shaft and the limiting ring, rapid air passage can be achieved in two directions of the hollow vertical beam. This structural design enables smoother air passage without the need to additionally add complex driving devices, not only simplifying the equipment structure but also improving the ventilation efficiency, providing a more efficient and convenient solution for solving the moisture and heat dissipation problems at the bottom of the solar panel.

[0036] Among them: In previous designs for ventilation, heat dissipation, and dehumidification of solar panels, an additional driving source was usually required to achieve air flow. This not only increased the cost of the equipment but also affected the ventilation effect due to malfunctions of the driving source. The current collecting and air drying assembly of this invention does not require an additional driving source and can enhance the ventilation effect relying only on natural wind. This design not only reduces the cost of the equipment but also improves the reliability and practicality of the equipment, making the ventilation, heat dissipation, and dehumidification functions of the solar panel more stable and durable, reducing the later maintenance cost and workload.

[0037] Among them: In the traditional solar panel installation structure, the support capacity of the guide rail for the solar panel is limited, and unstable situations may occur during long-term use or under the influence of external factors. In this invention, the presence of the hollow vertical beam is not only an important part of the current collecting and air drying assembly but also further strengthens the support capacity of the guide rail for the solar panel. The hollow vertical beam can bear greater weight and external forces, ensuring that the solar panel can maintain a stable installation state under various environmental conditions, improving the safety and reliability of the solar panel, and providing a strong guarantee for the long-term stable operation of the solar power generation system.

[0052] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0053] It should be noted that the solenoid valve only provides the function of discharging the water inside the water replenishing tank 210, the position sensor 1 and the position sensor 2 only provide the function of monitoring the position of the cleaning roller 29, the circulation module only provides the function of liquid circulation inside the water replenishing tank 210, the sequencer only provides the timing function, and the driving module only provides the function of opening and closing the snap cover. The working principle and specific structure of the above structures are all prior arts. Therefore, due to the generality of the above structures, the specific principles will not be described in detail hereafter.

[0054] Example 1, please refer to as Figures 1 to 7As shown in the figure, a solar energy device for buildings includes a number of guide rails 11. A solar panel 12 is installed on the top of the number of guide rails 11. A bionic cleaning component 2 is arranged on the outside of the guide rail 11. The bionic cleaning component 2 includes two trapezoidal seats 21. The two trapezoidal seats 21 are respectively fixedly connected to the outside of the outermost guide rail 11. Empty slots 22 are formed through the surfaces of the trapezoidal seats 21. Two annular protrusions extend outwards from the outer surfaces of the trapezoidal seats 21. A reciprocating lead screw 23 is rotatably connected inside the annular protrusions. A driving member 24 is installed outside the guide rail 11. The output shaft of the driving member 24 is fixedly connected to the reciprocating lead screw 23. Sliders 25 are slidably connected to the outer surfaces of the trapezoidal seats 21. Cylindrical protrusions are arranged on the outside of the sliders 25. The cylindrical protrusions are slidably connected to the outer surface of the reciprocating lead screw 23. Chutes 26 are formed in the middle of the sliders 25. Limit posts 27 are slidably connected inside the chutes 26. The limit posts 27 are also slidably connected inside the empty slots 22. A pulling and pressing piece 28 is fixedly connected to the side of the limit post 27 away from the reciprocating lead screw 23. A cleaning roller 29 is rotatably connected between every two pulling and pressing pieces 28. A water replenishing tank 210 is installed outside the guide rail 11 and on the side close to the driving member 24. A water draining tank 211 is installed outside the guide rail 11 and on the side away from the water replenishing tank 210.

[0055] It should be noted that an electromagnetic valve and a position sensor 1 are installed at the bottom of the water replenishing tank 210. A fastening cover is installed on the top of the water replenishing tank 210. A circulation module is installed outside the water replenishing tank 210. The circulation module is used to provide the function of liquid circulation. A sequencer and a position sensor 2 are installed outside the water replenishing tank 210. The inside of the water draining tank 211 presents a gradually shrinking shape. A number of water draining holes are formed at the bottom of the water draining tank 211. The empty slots 22 are trapezoidal. A water absorbing material is sleeved on the outer surface of the cleaning roller 29. Specifically, it is non-woven fabric. A driving module is installed outside the fastening cover to provide an automatic opening and closing function for the fastening cover. The liquid provided by the circulation module is water.

[0056] Specifically, as an important clean energy collection device, during long-term use, dust and other impurities will inevitably accumulate on the surface of the solar panel 12. The existence of these impurities will significantly reduce the light absorption and conversion efficiency of the solar panel 12. Therefore, it is necessary to regularly clean and maintain its surface.

[0057] When night falls and the solar panel 12 stops generating electricity, the sequencer starts to function. As the time control center of the entire cleaning process, the sequencer first controls the circulation module to start. The circulation module is responsible for providing liquid circulation inside the water replenishing tank 210. At this time, it injects water into the water replenishing tank 210.

[0058] After water is injected into the water replenishing tank 210, the cleaning roller 29 comes into full contact with the water and absorbs the water, making its surface moist. At the same time, in order to ensure that the water level in the water replenishing tank 210 is within an appropriate range, the solenoid valve will be opened in a timely manner to drain the excess water, ensuring that the cleaning roller 29 can absorb water sufficiently without being affected by excessive water for subsequent operations.

[0059] After the water replenishing and draining operations are completed, the driving module is started to drive the fastening cover to open. The opening of the fastening cover provides space for the subsequent movement of the cleaning roller 29, avoiding collision or interference with the fastening cover during the cleaning process.

[0060] Subsequently, the driving member 24 is started to drive the reciprocating lead screw 23 to rotate. During its rotation, the outer surface of the reciprocating lead screw 23 cooperates with the cylindrical protrusions on the surface of the slider 25. Due to the restrictive effect of the trapezoidal seat 21 on the slider 25, the slider 25 makes a reciprocating motion under the rotation of the reciprocating lead screw 23.

[0061] In the first stroke, the movement of the slider 25 will drive the limit post 27 to move synchronously. Under the restriction of the empty slot 22, the limit post 27 will slide in its top and the slot wall of the empty slot 22. As the limit post 27 moves, it will drive the tension sheet 28 and the cleaning roller 29 to rise synchronously, enabling the moist cleaning roller 29 to contact the surface of the solar panel 12. During the process of the cleaning roller 29 moving with the slider 25, its moist surface will adsorb and clean the dust and impurities on the surface of the solar panel 12, achieving the preliminary cleaning of the solar panel 12.

[0062] When the cleaning roller 29 moves to the end of the first stroke, the limit post 27 descends again and drives the cleaning roller 29 to descend. At this time, the cleaning roller 29 enters the water draining tank 211. Since the inside of the water draining tank 211 presents a gradually shrinking shape, the cleaning roller 29 will be squeezed during the process of entering the water draining tank 211, and the water in the non-woven fabric on its surface will be gradually squeezed out, making the surface of the cleaning roller 29 relatively dry.

[0063] Then, the reciprocating lead screw 23 continues to rotate, and the cleaning roller 29 starts the second stroke, that is, moves back in the reverse direction. During this process, the relatively dry cleaning roller 29 cleans the surface of the solar panel 12 again. Since the surface of the cleaning roller 29 is relatively dry at this time, it can effectively avoid the reattachment of dust and impurities to the surface of the solar panel 12 due to water residue during the cleaning process, further improving the cleaning effect.

[0064] When the cleaning roller 29 is about to reach above the water replenishing tank 210 during the second stroke, the second position sensor will monitor the position of the cleaning roller 29 and transmit a signal to the sequencer. After receiving the signal, the sequencer controls the drive member 24 to close, causing the cleaning roller 29 to pause until the set time allows its surface to dry. This ensures that the cleaning roller 29 remains dry when it returns inside the water replenishing tank 210, preventing problems such as bacteria growth or mildew due to moisture.

[0065] When the surface of the cleaning roller 29 is dry, the drive member 24 starts again and drives the cleaning roller 29 to return inside the water replenishing tank 210. After the cleaning roller 29 is inside the water replenishing tank 210, the first position sensor monitors the position of the cleaning roller 29 and feeds back a signal to the sequencer. The sequencer controls the drive member 24 to close, completing the reset of the cleaning roller 29.

[0066] Finally, the drive module starts again to close the fastening cover, thus completing a complete cleaning process for the solar panel 12.

[0067] It should be noted that during the first stroke of the cleaning roller 29, the cleaning roller 29 will push moisture and impurities into the drain tank 211. Since the cleaning roller 29 is squeezed by the drain tank 211 during movement, the internal moisture overflows. Therefore, the impurities pushed into the drain tank 211 by the cleaning roller 29 can flow out of the drain tank 211 synchronously with this part of the water, ensuring the effective removal of impurities during the cleaning process and further improving the cleaning effect.

[0068] Embodiment 2, on the basis of Embodiment 1, please refer to as Figures 8 to 10 shown, a confluence and air-drying assembly 3 is provided at the bottoms of the water replenishing tank 210 and the drain tank 211. The confluence and air-drying assembly 3 includes a plurality of hollow vertical beams 31. The plurality of hollow vertical beams 31 are all linearly arranged at equal intervals and installed at the bottoms of the water replenishing tank 210 and the drain tank 211. Inside each hollow vertical beam 31, two rows of limiting rings 32 are linearly arranged at equal intervals. A limiting shaft 33 is rotatably connected inside each limiting ring 32. A first confluence piece 34 and a second confluence piece 35 are respectively installed on the outer surfaces of the plurality of limiting shafts 33.

[0069] It should be noted that the limiting shaft 33 is set to be circular, but a rectangular protrusion is provided on its outside. The inside of the limiting ring 32 is set to be circular, but the side close to the inner wall of the hollow vertical beam 31 expands outward. The first confluence piece 34 and the second confluence piece 35 are staggered and arranged on the outer surface of the limiting shaft 33. The first confluence piece 34 and the second confluence piece 35 are both made of plastic material, specifically polyethylene material.

[0070] Specifically, when the air flow passes through the hollow vertical beam 31, it will strike the first confluence piece 34 and the second confluence piece 35 installed on the outer surface of the limit shaft 33. Since both the first confluence piece 34 and the second confluence piece 35 are made of polyethylene, a plastic material, which has certain flexibility and light weight characteristics, even a weak air flow can cause them to rotate around the limit shaft 33.

[0071] During the rotation of the first confluence piece 34 and the second confluence piece 35, they will drive the limit shaft 33 connected to them to rotate together. When the limit shaft 33 rotates, it will be restricted by the limit ring 32, thereby preventing it from over-rotating and ensuring the stability and controllability of the entire rotation process.

[0072] As the first confluence piece 34 and the second confluence piece 35 rotate, when the air flow passes through the first confluence piece 34, new tributaries will be generated. After this part of the tributaries cross the first confluence piece 34, under the guidance of the first confluence piece 34 and the restriction of the second confluence piece 35 beside it, they will impact the main stream of the air flow. Similarly, on the other side, when the air flow passes through the first confluence piece 34, new tributaries will also be generated, and this part of the tributaries will also converge with the main stream.

[0073] When these tributaries converge with the main stream, since their movement directions are the same, according to the principle of fluid mechanics, the velocity of the main stream air flow after convergence will be significantly increased. As the air flow continues to flow, this process of diversion and confluence will continue. When the air flow passes through multiple hollow vertical beams 31 and the first confluence pieces 34 and the second confluence pieces 35 thereon, new tributaries will be continuously generated and converge with the main stream, thereby continuously accelerating the air flow itself.

[0074] As the air flow speed increases, it is possible to achieve power-free air drying of the area between the tiles. The fast-flowing air can carry away the moisture in this area, accelerating the evaporation process of the moisture, thereby achieving the effect of air drying. At the same time, this accelerated air flow can also dissipate heat from this part of the area. The fast-flowing air can effectively carry away the heat, reducing the temperature of this area and preventing a series of problems that may be caused by excessive temperature.

[0075] It should be noted that when the wind blows into the hollow vertical beam 31 from the other side, the same effect will also be produced. This is because both the first confluence piece 34 and the second confluence piece 35 are movable parts, and they can rotate flexibly according to the direction and strength of the air flow, so as to always achieve the functions of diversion, confluence and accelerating the air flow.

[0076] In addition, the existence of the hollow vertical beam 31 not only provides a stable installation space for the confluence and air drying assembly 3, ensuring that each component can be accurately installed and operated, but also can provide a certain supporting force for the solar panel 12 on the guide rail 11.

[0077] Embodiment 3, a method for using solar energy in buildings, comprising the following steps:

[0078] Step 1: Check whether the connections between the solar panel 12 and the controller are firm, whether the wires are damaged or short-circuited, confirm whether the grounding protection of the system is good, and at the same time check whether there is dust, stains, or obstructions on the surface of the solar panel 12. If so, clean it in time to ensure the lighting effect of the solar panel 12;

[0079] Step 2: Start the system to make the system start working;

[0080] Step 3: Monitor the system operation status. Observe the power generation power, voltage, and current parameters of the solar panel 12 through the display screen on the controller;

[0081] Step 4: Connect the electrical appliance to the output port of the system, and then the electricity generated by the solar panel 12 can be used. Note that the power of the electrical appliance should be within the load-bearing range of the system to avoid overload;

[0082] Step 5: Perform regular maintenance. Regularly check the surface cleanliness of the solar panel 12, remove dust, leaves, and sundries, and keep the surface of the solar panel 12 clean.
