The present disclosure provides a photovoltaic module. The photovoltaic module includes three cell string groups (11, 12, 13) connected in series, the three cell string groups each include four cell strings (14) in parallel. The cell string (14) includes multiple electrically connected cells (15), which are quarter cells cut from the whole cell. Among them, the length L1 of the cell is 182.3mm, and the width L2 of the cell satisfies 46.675mm < L2 < 53.25mm. The photovoltaic module adopts a four in four circuit design, which means that the cells (15) are quarter cells cut from the whole cell, and each cell string group (11-13) includes four parallel cell strings (14). This not only reduces the current in a single cell string and lowers the power loss of a single cell string, but also avoids the overall output current of the photovoltaic module caused by the use of cut cells. This ensures that the overall output current of the photovoltaic module in this embodiment is equal to that of the conventional photovoltaic module using two-piece cells, ensuring the overall power of the photovoltaic module in the present disclosure.

Provided are an analysis and management unit, and an interactive management system and method for a photovoltaic (PV) power station. The system employs "language interaction" to simplify a user input at a terminal, reducing input requirements and lowering the operation threshold for users. A large language model (LLM) is innovatively introduced, which includes an input side for receiving a comprehensive input instruction in text form and an output side for providing a natural language-based output instruction. The front-end input and back-end processing and output are based on natural language processing, which better aligns with the usage requirements of conventional users. In the final specific execution, the natural language-based output instruction is converted into a corresponding format for specific execution, reducing the processing difficulty of the management method. Furthermore, the data sources during processing are more diverse, resulting in enhanced processing capability of the system and enabling the method to address a wider range of problems. Accordingly, this application enhances user experience while better enabling all-weather and comprehensive management of the PV power station.

0000 In this patent document, the partial energy processing (PEP) concept is developed to achieve a high-efficiency and full MPPT range PV MIC. For PEP the energy is flown from the source to the load through multiple paths. The total energy then is divided into arbitrary portions in power-time plane and each portion is transferred through a different path to achieve the best conversion performance. A three path PEP structure that is specifically suitable for PV MIC application is proposed and realized in component level. A 220 W prototype converter is implemented to justify the converter principal of operation and analyses. Using the proposed PV MIC, MPPT is achieved for the full range of the PV power generation while 99.6% to 96.5% efficiency is achieved for the power mismatches in the PV module ranging from 0 to 50% of the maximum module power generation capability, respectively. The efficiency drop is shown to be linear with power mismatch level without any abrupt reductions that is commonly observed in conventional PV module integrated converters.
