[0002] As global energy demand continues to soar and environmental awareness continues to increase, solar energy, as a clean and renewable energy source, is becoming increasingly popular. However, traditional solar photovoltaic systems mainly use photovoltaic panels as the core to convert sunlight into electrical energy, but there are many challenges in this process. How to improve the efficiency of solar energy utilization has become the key to research and technological development. First of all, traditional solar photovoltaic systems face the problem of low energy conversion efficiency. Although the technology of photovoltaic panels is constantly developing, the energy conversion efficiency of most products on the market is still limited. This means that most of the sunlight that shines on the photovoltaic panels is not fully converted into electrical energy, but is dissipated as heat or other forms. Therefore, improving energy conversion efficiency has become an important research direction for solar photovoltaic technology.

[0003] Traditional solar photovoltaic systems also have certain limitations in storing and managing electrical energy. Due to the intermittent and unpredictable nature of solar energy, how to effectively store and manage excess electrical energy has become an urgent problem to be solved.

Therefore, developing new energy storage technologies and improving the efficiency of electrical energy storage and management are of great significance for the widespread application of solar energy. In addition, traditional solar photovoltaic systems often cannot maximize the adaptation to different environmental conditions and user needs. In different geographical locations and climatic conditions, the intensity and exposure time of sunlight are different, which requires solar photovoltaic systems to adapt to these changes. At the same time, user needs are also diverse. How to design and optimize solar photovoltaic systems according to user needs has become a problem worth studying. Finally, traditional solar photovoltaic systems lack the ability to effectively interact with the power grid. In modern power systems, the power grid plays a vital role, and how solar photovoltaic systems can effectively interact with the power grid has become a key factor in determining their application prospects. For example, when there is an excess of photovoltaic power generation, how to transmit the excess electricity to the power grid, and how to dispatch photovoltaic power generation to relieve pressure when the grid load is peak, are both urgent issues that need to be resolved.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example:

[0030] Please see attached Figure 5The embodiment of the present invention provides a solar photovoltaic power generation and energy storage integrated device, including a photovoltaic power generation component 1, the photovoltaic power generation component 1 is used to capture sunlight and convert it into electrical energy, the photovoltaic power generation component 1 is electrically connected to a battery storage unit, the battery storage unit is used to store the collected electrical energy, the output end of the battery storage unit is electrically connected to an energy management system, the output end of the energy management system is electrically connected to an energy conversion module, the energy conversion module is used to convert direct current into alternating current suitable for household and industrial electricity, the energy management system includes an advanced algorithm unit, the advanced algorithm unit is used to monitor and adjust photovoltaic power generation and battery discharge behavior in real time;

[0031] Photovoltaic power generation components 1 use advanced photovoltaic cell technology to capture sunlight and convert it into electrical energy, optimize the efficiency of photoelectric conversion, and thus generate more electricity under the same lighting conditions. Subsequently, the generated electricity is efficiently stored by the battery storage unit, which uses advanced battery technology, such as lithium-ion batteries, to store excess electricity when the supply of electricity exceeds demand, and release electricity when demand exceeds production to ensure the stability of power supply. The power management system (EMS) monitors and adjusts the charging and discharging behavior of photovoltaic power generation and batteries in real time through its advanced algorithm unit to optimize the overall efficiency of energy production, storage and use. Finally, the energy conversion module converts the direct current in the battery into alternating current suitable for home and industrial use, reduces energy loss through an efficient conversion process, and provides high-quality power output. The entire device integrates efficient photovoltaic power generation, power storage, management system and energy conversion technology, which not only significantly improves the comprehensive utilization rate of solar energy and reduces energy costs, but also improves the stability and reliability of the power system. This innovative solution provides an environmentally friendly, efficient and economical energy option for modern homes and industries, promotes the development of renewable energy technology, and has important social and economic value.

[0032] Please see attached Figure 1 -Attached Figure 4 , an adjustment mechanism is provided at the bottom of the photovoltaic power generation component, the adjustment mechanism includes a base frame 2 and a fixed column 8, the fixed column 8 is located above the base frame 2, the fixed column 8 is fixedly connected to the lower surface of the photovoltaic power generation component 1, a support rod 5 is fixedly connected to the upper surface of the base frame 2, a consolidation rod 3 is fixedly connected to the opposite side of the support rod 5, and the other side of the consolidation rod 3 is fixedly connected to the upper surface of the base frame 2, a connecting rod 10 is fixedly connected between the support rods 5, and connecting blocks 11 are fixedly connected on both sides of the connecting rod 10, an arc frame 4 is provided on the inner side of the connecting block 11, racks 7 are provided on both sides of the arc frame 4, the connecting block 11 slides inside the rack 7, the arc frame 4 is connected to the fixed column 8, and the rack 7 is fixedly connected to the lower surface of the arc frame 4, a motor 9 is fixedly connected to one side of the connecting block 11, and a gear 12 is fixedly connected to the output end of the motor 9, the gear 12 rotates inside the connecting block 11, and the gear 12 is meshed with the rack 7;

[0033] When the external environment or system requirements change, the motor 9 will respond quickly, start and control the gear 12 to rotate. The rotation of the gear 12 not only drives the block 11 connected to it to rotate synchronously, but also transmits power to the arc frame 4 through the meshing relationship with the rack 7 on the lower surface of the arc frame 4. This meshing relationship ensures that the arc frame 4 can deflect and rotate in a precise manner. This deflection is not only flexible, but also very stable, and can maintain a stable rotation angle even under strong winds or other external interference. This design not only simplifies the mechanical structure, but also improves the reliability of the system. The deflection and rotation of the arc frame 4 is a key step in achieving the angle adjustment of the photovoltaic panel. As a direct recipient of solar energy, the angle of the photovoltaic panel has a decisive influence on the efficiency of capturing solar energy. By adjusting the deflection angle of the arc frame 4, the photovoltaic panel can adjust its angle in real time to maximize the capture of sunlight. This adjustment not only improves the power generation efficiency of the photovoltaic panel, but also ensures that the photovoltaic system can maintain efficient power generation under different times and conditions. The motor 9 will automatically adjust the rotation speed and direction of the gear 12 according to the system-set parameters or real-time environmental data, thereby achieving precise adjustment of the angle of the photovoltaic panel. This automatic adjustment not only improves the intelligence level of the system, but also greatly reduces the operation and maintenance costs.

[0034] Please see attached Figure 5 The photovoltaic power generation component 1 includes multiple layers of high-efficiency photovoltaic cells, each layer of photovoltaic cells has different spectral response characteristics to utilize a wider band range of sunlight, and the battery storage unit includes a battery pack with multiple chemical compositions, each chemical composition of the battery is specifically used to optimize performance under different discharge rate and temperature conditions.

[0035] The multi-layer high-efficiency photovoltaic cell components and battery storage units with various chemical compositions work together to achieve significantly improved utilization of solar energy and storage efficiency of electrical energy. The photovoltaic power generation components of this device effectively capture a wider band of sunlight and convert it into electrical energy through its multi-layer structure, each layer of which is optimized for the response characteristics of different spectra. This not only improves the efficiency of light-to-electricity conversion, but also enables the device to effectively generate electricity in different weather conditions and different time periods of the day. At the same time, the design of the battery storage unit takes into account the performance optimization of batteries with different chemical compositions under specific discharge rates and temperature conditions, allowing the system to dynamically select the most suitable battery pack for charging and discharging according to current environmental conditions and load requirements. Such intelligent storage management not only improves energy storage efficiency, but also extends the service life of the battery and ensures stable and reliable operation of the system under various environmental conditions.

[0036] The power management system further includes an algorithm for dynamically adjusting the charging and discharging strategies based on predicted solar production and power demand patterns, the energy conversion module includes an inverter with high-frequency switching technology and improves the quality of AC power output, and the power management system includes a machine learning unit that is capable of self-learning and adapting to the user's power usage habits.

[0037] By integrating prediction-based algorithms, machine learning units, and inverters with high-frequency switching technology, the system can significantly improve the efficiency of solar energy utilization, optimize the storage and use of electrical energy, and improve the quality of AC output. Specifically, the prediction-based algorithms built into the EMS use historical data and real-time environmental monitoring, such as weather conditions and seasonal changes, to predict solar energy production and users' power demand patterns. This predictive capability enables dynamic adjustment of charging and discharging strategies, such as increasing energy storage when expected solar energy production is above average, or charging in advance before expected peak demand periods to ensure the stability and efficiency of power supply. This predictive adjustment strategy helps balance production and consumption, reduce energy waste, and improve the system's adaptability to unstable energy input. The inverter with high-frequency switching technology used in the energy conversion module converts direct current into high-quality alternating current for home and industrial use through a highly efficient energy conversion mechanism. This technology improves the quality of power and the efficiency of equipment operation by reducing energy loss during the conversion process and optimizing the waveform of the output current. This not only reduces dependence on the power grid, but also provides a more stable and secure power supply for end users. The machine learning unit of EMS further enhances the intelligence level of the system. By analyzing the user's electricity usage habits, it self-learns and adjusts the power distribution strategy to adapt to changes in user needs. This adaptive capability means that the system can automatically optimize its operating mode in different time periods. For example, it can store more energy when the user's electricity consumption is low and release energy during peak hours, thereby achieving more economical and efficient energy management. The introduction of the machine learning unit not only improves the efficiency of energy utilization, but also creates a more personalized and intelligent energy usage experience for users.

[0038] The battery storage unit includes a cooling system that uses the heat generated by the battery itself to drive a cooling cycle, thereby maintaining the battery operating temperature within an optimal range without external energy input. The power management system includes an interface for communicating with the power grid, allowing the device to dynamically provide or absorb energy to the grid according to the needs of the grid;

[0039] The self-heat recovery cooling system of the battery storage unit and the ability of the energy management system (EMS) to communicate with the power grid further enhance the efficiency and intelligence of the entire system. The cooling system of the battery storage unit uses an innovative heat recovery mechanism to drive the cooling cycle through the heat generated by the battery itself during operation. This self-powered cooling method avoids dependence on external energy, thereby significantly improving energy efficiency and environmental friendliness. By maintaining the battery operating within the optimal temperature range, it not only extends the battery life, but also improves the safety and reliability of the entire energy storage system. The device's energy management system contains a specially designed communication interface that enables the device to communicate with the power grid in real time. This feature enables the device to dynamically adjust its power output or input according to the current demand and supply conditions of the power grid to support the stable operation of the power grid. When there is an oversupply of electricity, the system can store the excess electricity; and when demand peaks, it can supply power to the power grid to help balance the power grid load and improve the energy efficiency and flexibility of the power grid. This dynamic energy interaction capability not only optimizes the efficiency of energy utilization, but also promotes the integration of renewable energy, providing important support for the realization of smart energy management and the promotion of sustainable energy development.
