Description

Technical Field

[0001] This invention relates to the field of equipment manufacturing, and in particular to a rooftop photovoltaic compensation system that can intelligently adjust sunlight. Background Technology

[0002] Solar energy is a clean energy source. With the development of solar energy application technology, photovoltaic power generation is receiving increasing attention and application. Solar photovoltaic power generation meets people's needs for daily life and production. As a clean energy source, solar energy is already one of the energy sources that people cannot do without today. With the development of photovoltaic power generation technology, how to improve the energy output efficiency of photovoltaic modules under limited space and less than ideal lighting conditions has become a key technical issue.

[0003] Traditional fixed photovoltaic (PV) installations are significantly affected by changes in the angle of sunlight, resulting in large fluctuations in power generation efficiency. After the PV panels are installed, the gaps between them prevent efficient utilization of solar energy. Therefore, solar tracking technology is applied to PV installations. Existing solar tracking technology tracks the angle of sunlight through a system that drives an automatic tracking and adjustment bracket at the bottom of the PV installation to achieve sunlight tracking. However, this automatic tracking and adjustment bracket is complex, costly, and has poor stability. Furthermore, prolonged exposure to high-intensity sunlight causes the PV panels to overheat, leading to performance degradation. Prolonged high-temperature operation can cause hot spot effects, resulting in reduced output power or complete failure. To address this, existing technology proposes an automatic tracking and adjustment PV power station bracket (application number: CN202220641357.8). This patent achieves automatic tracking and adjustment of the solar PV panels, resulting in a smaller angle between the panels and sunlight, thereby increasing the light intensity per unit area and improving PV power generation efficiency. However, it still does not solve the problems of some unutilized sunlight and the hot spot effect.

[0004] Existing solar tracking systems all drive photovoltaic (PV) devices to track sunlight, resulting in higher costs, more complex structures, larger sizes, and relatively higher maintenance costs. Tracking is achieved by adjusting the overall orientation of the PV devices, but this method lacks adaptability under complex lighting conditions such as cloudy weather or shading, as individual adjustments to the PV panels are not possible. Retrofitting existing PV systems with solar tracking is also too time-consuming and costly. Therefore, we propose a rooftop PV compensation system. Summary of the Invention

[0029] This invention relates to a rooftop photovoltaic compensation system with intelligent solar illumination adjustment. It features a compact structure, high control precision, low cost, and flexible deployment, making it particularly suitable for building rooftops, small-scale photovoltaic power stations, and off-grid photovoltaic applications in remote areas. By intelligently adjusting the light compensation components, the system can significantly increase the power generation of the photovoltaic panels and effectively reduce the damage to the inverter caused by localized high temperatures on the photovoltaic panels. It also reduces the impact of potential-induced degradation on the solar panels, extends equipment life, and provides a feasible technical path for the efficient operation of photovoltaic systems in complex lighting environments.

[0030] The present invention will be further described below, specifically as follows:

[0031] A rooftop photovoltaic compensation system that can intelligently adjust solar illumination, see [link / reference]. Figures 1 to 9The rooftop photovoltaic compensation system includes a photovoltaic control device 2, a photovoltaic detection system 3, an anemometer 1, and photovoltaic equipment. The photovoltaic control device 2 includes a drum-shaped refractor 21, a pneumatic deflector 24, an automatic cleaning and cooling device 25, and an intelligent integrated water and air pump device. The drum-shaped refractor 21 is fixed to the top beam of the photovoltaic equipment via the pneumatic deflector 24. Reflective coated curtains 22 and curtain switch devices 23 for pulling / closing the reflective coated curtains 22 are provided on the front and rear sides of the drum-shaped refractor 21. The intelligent integrated water and air pump device is located on the side of the photovoltaic equipment. The integrated water-air pump device houses a main control circuit board, an air pump, and a water-air mixing pump. The intelligent integrated water-air pump device supplies air to the pneumatic deflector 24 via the air pump and water-air mixture pump to the automatic cleaning and cooling device 25 via the water-air mixing pump. The main control circuit board is electrically connected to the photovoltaic detection system 3, the anemometer 1, the air pump, and the water-air mixing pump respectively. The main control circuit board can regulate and control the air pressure of the air pump and the water-air mixing pump based on the data collected by the photovoltaic detection system 3 and the anemometer 1, driving the waist-drum-shaped refractor 21, the pneumatic deflector 24, and the automatic cleaning and cooling device 25 to work under different operating conditions.

[0032] This invention utilizes a photovoltaic detection system 3 to accurately detect the lighting conditions on the photovoltaic equipment and the operating parameters of the photovoltaic panels. When the lighting on the photovoltaic equipment is weak, the power generation efficiency of the photovoltaic panels is low. This invention, through the design of a drum-shaped refractor 21 and a reflective coated curtain 22, can reflect unused sunlight above the photovoltaic equipment onto the photovoltaic panels for photovoltaic compensation, thereby improving the photoelectric conversion rate. The tilt angle of the drum-shaped refractor 21 can be adjusted by a pneumatic deflection device 24, thereby changing the reflection angle and ensuring that the sunlight is accurately reflected onto the photovoltaic panels.

[0033] Since the angle of sunlight changes over time, the drum-shaped refractor 21 is designed to be transparent to better reflect light. The reflection of light from different directions is achieved by opening and closing the reflective coating curtains 22 on both sides. Specifically, when light shines on the left, the reflective coating curtain 22 on the right is opened, forming a reflective surface with the drum-shaped refractor 21. Light passes through the reflective coating curtain 22 on the left side of the drum-shaped refractor 21, forming a reflective surface with the drum-shaped refractor 21. Light then passes through the right side of the drum-shaped refractor 21 and is reflected onto the photovoltaic panel on the right side of the photovoltaic device for compensation. Furthermore, the curtain switch device 23 can control the degree to which the reflective coating curtain 22 is pulled down, thereby adjusting the refraction and transmission ratio of light on the drum-shaped refractor 21.

[0034] If the photovoltaic panel is obstructed by external objects such as leaves, bird droppings, or shadows, these areas become a load, consuming a large amount of electrical energy generated by other batteries and converting it into heat energy. This causes a sharp increase in the local temperature of the photovoltaic equipment, leading to battery performance mismatch and hot spot effects. This not only affects the safety performance of the equipment but also the photoelectric conversion efficiency. To solve this problem, this invention designs an automatic cleaning and cooling device 25. The automatic cleaning and cooling device 25 includes a cleaning nozzle 251 and a water-air pipe 252. The cleaning nozzle 251 is connected to the mixed gas output end of a water-air mixing pump through the water-air pipe 252. The water-air mixing pump is connected to an air inlet pipe and a water inlet pipe, with the water inlet pipe connected to a tap water pipe. Multiple cleaning nozzles 251 are located on the front and rear sides of the drum-shaped refractor 21, and are evenly spaced along the length of the photovoltaic equipment. An automatic cleaning and cooling device 25 sprays an appropriate amount of water mist to reduce the temperature of the photovoltaic panel, optimize the working environment, and improve photovoltaic power generation efficiency. The cleaning effect can be achieved by adjusting the water and air pressure. During operation, when the main control circuit board detects a localized hot spot effect on a photovoltaic panel through the photovoltaic panel sensor 32, a water-air mixing pump sprays water mist to cool the photovoltaic panel and simultaneously blows away dirt, thus cleaning the surface of the photovoltaic panel and preventing hot spot effects caused by a rapid increase in localized temperature.

[0035] The photovoltaic detection system 3 includes a light control sensor 31 and a photovoltaic panel sensor 32. The light control sensor 31 and the photovoltaic panel sensor 32 are mounted on the photovoltaic equipment and are electrically connected to the main control circuit board. The photovoltaic panel sensor 32 is mounted on the photovoltaic panel of the photovoltaic equipment and collects parameters such as the output current, voltage, power, temperature, and humidity of the photovoltaic panel. The light control sensor 31 is used to collect illumination data and sense the light intensity. The light control sensor 31 is located in the gap between the photovoltaic panels of the photovoltaic equipment and can also sense whether the compensation light angle reflected by the drum-shaped refractor 21 is on the photovoltaic panel. If it is not on the photovoltaic panel, the tilt angle is adjusted by the pneumatic deflection device 24 to optimize the illumination conditions.

[0036] The pneumatic deflection device 24 can adjust the tilt angle of the drum-shaped refracting mirror 21 by its own expansion and contraction, thereby adjusting the direction of light refraction. The specific structural design of the pneumatic deflection device 24 is as follows: The pneumatic deflection device 24 consists of two sets of hollow pleats 241 and two sets of air guide pipes 242. The intelligent integrated water-air pump device is equipped with two differential pressure air pumps. The air guide pipes 242 consist of an air inlet pipe and an air return pipe. The two sets of hollow pleats 241 are connected to the air outlet and air return port of the two differential pressure air pumps through the air guide pipes 242, respectively. The two differential pressure air pumps supply differential pressure air to the two sets of hollow pleats 241, respectively. The hollow pleats 241 adjust the tilt angle of the drum-shaped refracting mirror 21 by their own expansion and contraction, thereby adjusting and changing the direction of light reflection, so that the light passing through the photovoltaic equipment can be reflected onto the photovoltaic panel through the drum-shaped refracting mirror 21, realizing efficient tracking and focusing of sunlight.

[0037] The drum-shaped refractor 21 is a transparent, inflatable, retractable airbag structure. The two sides of the drum-shaped refractor 21 are foldable arc-shaped structures, while the top and bottom are transparent sheet metal structures. The interior of the drum-shaped refractor 21 contains a hollow refraction chamber. The arc-shaped structures on both sides of the drum-shaped refractor 21 form a certain curvature, which is beneficial for focusing and reflecting light, preventing light from being easily dispersed and concentrating it on the photovoltaic panel for photoelectric conversion. The top and bottom of the sheet metal structure have good supporting stability. The inflatable retractable airbag structure allows the gas inside the drum-shaped refractor 21 to be extracted when there is sufficient light and supplemental lighting is not needed, or in windy weather. The inflatable retractable airbag structure can then be folded and stored away. To enable the folding and storage of the drum-shaped refractor 21 when not in use, the intelligent integrated water-air pump device is equipped with an air pump for inflating and deflating it. The air inlet and outlet of the air pump are connected to the inside of the drum-shaped refractor 21 through air inlet pipes and air outlet pipes. The intelligent integrated water-air pump device can open and close the FF0C of the drum-shaped refractor 21 to ensure the stability and accuracy of the drum-shaped refractor 21.

[0038] To achieve automatic rewinding of the reflective coated curtain 22, see [link / reference]. Figure 7 and Figure 8A curtain switch device 23 was designed, with a structure identical to the winding structure of an electric roll-up banner. The curtain switch device 23 consists of a main rotating cylinder 231 and a secondary rotating cylinder 232, which are respectively fixed to the upper and lower ends of a drum-shaped refractor 21. The main rotating cylinder 231 contains a main rotating shaft 233 driven by a motor, which rotates to achieve the winding operation of the reflective coated curtain 22. The secondary rotating cylinder 232 contains a secondary rotating shaft 234 and a spring return device 235. When the main rotating shaft 233 winds up, the reflective coated curtain 22 drives the secondary rotating shaft 234 to rotate, while the spring return device 235 is in a stretched state. When the main rotating shaft 233 winds up, the reflective coated curtain 22 drives the secondary rotating shaft 234 to rotate, and the spring return device 235 is in a stretched state. When the rotating shaft 233 rotates in the reverse direction to unwind, the elastic reset of the spring reset device 235 drives the auxiliary rotating shaft 234 to rotate in the reverse direction, performing the winding operation of the auxiliary rotating shaft 234. This achieves the up-and-down winding movement of the reflective coating curtain 22. The upper half of the reflective coating curtain 22 is coated with a reflective coating, and the lower half is transparent. The upper and lower ends of the reflective coating curtain 22 are fixedly connected to the rotating shafts of the main rotating cylinder 231 and the auxiliary rotating cylinder 232, respectively. When light blocking is required, the lower end of the reflective coating curtain 22 is wound up, pulling down the upper half of the reflective coating curtain 22 to block light. When light blocking is not required, the upper end of the reflective coating curtain 22 is wound up, exposing the transparent part for light transmission.

[0039] This invention adds an anemometer 1, which is installed on top of the drum-shaped refractor 21 of the photovoltaic control device 2 and is electrically connected to the main control circuit board in the intelligent integrated water-air pump device. When the wind speed or direction changes, the main control circuit board adjusts the air pressure of the air pump based on the feedback from the anemometer 1 to ensure the stability of the light refraction device, avoid the influence of natural wind on the light refraction device, and ensure the accuracy of the light deflection angle. When the wind force is strong, to prevent damage to the photovoltaic control device 2, when the anemometer 1 detects that the wind speed exceeds the set threshold, the intelligent integrated water-air pump device controls the air pump to evacuate the gas in the drum-shaped refractor 21 and the pneumatic deflection device 24, and the photovoltaic control device 2 is stored away for safety protection.

[0040] In summary, this invention can automatically adjust the angle of light refraction using a pneumatic deflector 24 when sunlight intensity is insufficient or unevenly distributed, flexibly adjusting the direction and proportion of light refraction to achieve efficient utilization of sunlight. Simultaneously, the automatic cleaning and cooling device 25 reduces the temperature of the photovoltaic panels, optimizing the operating environment of the photovoltaic system and improving photovoltaic power generation efficiency. By comprehensively adjusting sunlight and wind speed, it significantly improves photovoltaic power generation efficiency, effectively reduces the temperature rise and hot spot effect of the photovoltaic panels, enhances the safety and stability of the photovoltaic equipment system, and improves the light energy utilization and adaptability of the rooftop photovoltaic system, providing an efficient and intelligent solution for solar photovoltaic power generation.
