Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic management, and particularly relates to a household photovoltaic management system and method. BACKGROUND

[0002] Household photovoltaic projects have the outstanding characteristics of small, scattered and numerous, that is, the scale of a single project is small, the geographical location is scattered, and a large number of farmers are involved, which brings severe challenges to the management of the project in terms of scale and standardization.

[0003] In the prior art, the traditional management mode highly depends on manual work and has many disadvantages: in the market development and installation process, the process is complicated and the cycle is long, and it is difficult to efficiently cover and manage scattered farmers; in the acceptance process, the construction party, the supervision party and the construction party need to work offline in series, which is low in efficiency and seriously slows down the grid connection progress; in the operation and maintenance process, it is impossible to effectively monitor thousands of distributed sites in real time, and the fault discovery and processing are delayed, resulting in loss of power generation; in the electricity fee settlement, manual checking and collection are relied on, the fund recovery cycle is long and the risk is high; in the subsequent project development decision, there is a lack of comprehensive analysis of information such as power grid capacity and power generation data, and there is blindness. In addition, the existing mode has a complex process and high cost in financing, and it is difficult to effectively support the rapid rolling development of the project.

[0004] Therefore, there is an urgent need in the art for an innovative system and method capable of integrated management and control of household photovoltaic projects throughout the life cycle to solve the above management difficulties. SUMMARY

[0005] The main purpose of the present application is to overcome the deficiencies in the prior art and provide a household photovoltaic management system and method.

[0006] The technical scheme adopted by the present application to achieve the technical purpose is: a household photovoltaic management system, the system comprising: An integrated digital management platform server. The server is the core hardware carrier and operation center of the whole system, as a unified physical or virtual server, carrying and running all subsequent functional modules, interacting with other external systems (such as power grid company settlement system, farmer APP terminal, site data collector) through network, and providing data storage, exchange and collaborative work for internal modules.

[0007] The market development and installation module is configured to receive and process household photovoltaic project installation applications through an online installation application interface. The module is the interface between the system and the front-end market users. It connects with the mobile APP or web page used by farmers through the online installation application interface, receives the initial project application information, and its processing functions include formatting, checking, and storing the application information, and possibly initiating subsequent internal approval or task distribution processes.

[0008] The electricity fee automatic transfer module is configured to interface with the power grid company settlement system to perform automatic transfer operations according to the electricity fee transfer agreement. The module is the core hub of the system and the fund flow. It interfaces with the power grid company settlement system through dedicated lines or encrypted APIs to obtain electricity settlement raw data. The module has a rule engine based on the electricity fee transfer agreement preset inside, which can automatically calculate the benefits of each party and instruct the bank or payment system to transfer funds from the power grid account to the project company account.

[0009] The operation and maintenance monitoring module is configured to communicate with the data collectors of each household photovoltaic station to monitor real-time operation data and generate operation and maintenance instructions. The module is the brain and decision center of the system. It obtains power generation data from the operation and maintenance monitoring module and obtains power grid data such as transformer capacity and transformation plans from external power grid information systems. Through built-in data mining and algorithm models, it analyzes the correlation between the two types of data. The output decision suggestions, such as the transformer capacity in a certain village being sufficient and suitable for priority development, provide data-driven action guidelines for the market development team.

[0010] The data analysis and decision support module is configured to analyze power generation data and power grid data and output decision suggestions for project rolling development. The module is the brain and decision center of the system. It obtains power generation data from the operation and maintenance monitoring module and obtains power grid data such as transformer capacity and transformation plans from external power grid information systems. Through built-in data mining and algorithm models, it analyzes the correlation between the two types of data. The output decision suggestions, such as the transformer capacity in a certain village being sufficient and suitable for priority development, provide data-driven action guidelines for the market development team.

[0011] Preferably, the market development and installation module further integrates a remote acceptance sub-module that provides an interactive interface for the construction party, the supervision party, and the construction party to perform a three-level acceptance process. This module connects the construction party, the supervision party, and the construction party in different locations in the digital space through a unified interactive interface, so that they can submit acceptance materials, upload on-site media, and fill out acceptance opinions through this interface to collaboratively complete the three-level acceptance process of the construction party-supervision party-construction party. This converts the offline and serial acceptance process into an online and parallel process, significantly shortening the period from project construction to grid connection.

[0012] Preferably, the system further includes a financing service interface module, configured to connect with the financial institution's system to transmit project data required for financing in a direct leasing mode and track the financing approval status. This module is specifically responsible for connecting with the financial institution's system. In the "direct leasing mode," it transmits core project-related data (such as equipment lists, contracts, etc.) to the financial institution. At the same time, it can also receive and track feedback on the approval status from the financial institution's system.

[0013] This invention also provides a method for managing residential photovoltaic (PV) systems, the method comprising: managing residential PV projects distributed across multiple administrative regions throughout their entire lifecycle using an integrated digital management platform; the digital management platform performing the following steps: S1. Market Development and Application: Through the online application integrated into the digital management platform, applications for distributed photovoltaic projects from scattered farmers are received and processed, simplifying the application and grid connection procedures. S2. Electricity Fee Settlement: Through connection with the power grid company's system, based on the electricity fee transfer agreement signed with farmers, the electricity fee income that farmers are entitled to is automatically transferred from the power grid company's settlement account to the project company's account; S3, Operation and Maintenance Monitoring: By communicating with the data acquisition devices deployed at each household photovoltaic site, the system monitors the operating status of the power station in real time, and automatically identifies and alarms inefficient, non-power-generating, and faulty power stations, generating operation and maintenance work orders; S4. Data Analysis and Decision Support: Analyze the collected power generation data and power grid planning data to obtain available capacity data and subsequent renovation plans for township and village-level transformers, providing a basis for decision-making for the accurate and rolling development of subsequent projects.

[0014] Preferably, step S1, market development and application, further includes: integrating a three-level acceptance process into the online application, enabling the construction party, the supervision party, and the construction party to remotely participate in and complete the project acceptance through the application, thereby improving acceptance efficiency.

[0015] Preferably, in step S3, maintenance monitoring, after the digital management platform generates a maintenance work order, it dispatches maintenance personnel and completes fault elimination within 48 hours.

[0016] Preferably, the method further includes a financing management step: Through the aforementioned digital management platform, data is exchanged with the systems of financial institutions to initiate financing applications in a direct leasing model; The digital management platform provides financial institutions with project equipment lists, construction progress, and power generation revenue data to optimize the financing review and approval process and assist in achieving value-added tax deductions.

[0017] Preferably, the method adopts a bottom-up development strategy during the project development phase, assigning development tasks to subcontractors and tracking their development progress through the digital management platform, and directly penetrating target farmers using the subcontractors' local channels.

[0018] The working principle of this residential photovoltaic management system and method is as follows: Based on an integrated digital management platform, the system receives and processes online application requests from farmers through a market development and application module, and integrates a remote acceptance process to achieve online collaborative acceptance by the construction, supervision, and development parties. The system uses an automatic electricity fee transfer module to connect with the power grid settlement system, and automatically transfers electricity fees from farmers' accounts to the project company according to the agreement. The operation and maintenance monitoring module collects real-time operating data from each site, automatically identifies faults and dispatches work orders to ensure that faults are eliminated within 48 hours. The data analysis module integrates power generation and power grid data to provide decision support for the rolling development of subsequent projects. At the same time, the system connects with financial institutions through a financing service interface in a direct leasing model, optimizes the financing approval process, and assists in tax deductions, thereby achieving efficient management of the entire life cycle of distributed residential photovoltaic projects from development, construction, operation to financing.

[0019] Compared with the prior art, the beneficial effects of the present invention are: This residential photovoltaic management system and method, through an integrated digital management platform, seamlessly integrates previously fragmented aspects such as market development, application and acceptance, operation and maintenance monitoring, electricity bill settlement, data analysis, and financing management, forming an efficient management closed loop. It completely overcomes the problems of management control and inefficiency caused by the "small, scattered, and fragmented" characteristics of projects, and realizes digital and intensive management throughout the entire life cycle.

[0020] This residential photovoltaic management system and methodology, with its online application and integration remote three-level acceptance process, transforms the offline sequential process into an online parallel process. This significantly shortens the project's cycle from construction to grid connection, enabling same-month construction, grid connection, and revenue generation. An automated electricity fee transfer mechanism ensures timely and secure revenue recovery, while data-driven operation and maintenance monitoring and a 48-hour defect elimination commitment minimize power generation losses, greatly improving operational efficiency and economic benefits.

[0021] This household photovoltaic management system and method, through comprehensive analysis of real-time power generation data and grid planning data (such as the capacity of township and village-level transformers), provides a scientific basis for the precise and rolling development of subsequent projects, thereby providing accurate decision support, reducing development risks, avoiding resource waste and investment risks, and achieving high-quality development.

[0022] This residential photovoltaic management system and method connects directly with financial institutions through a financing service interface module in a "direct leasing model," optimizing the approval process and allowing access to VAT deduction policies. This significantly reduces the project's financing costs and tax burden, providing financial support for the rapid promotion of the project, thereby innovating the financing model and effectively reducing costs.

[0023] This household photovoltaic management system and method avoids financial risks such as photovoltaic loans through a pure rental model, effectively protecting the interests of farmers and ensuring stable income growth for them every year. At the same time, this model helps local governments with tax revenue, industrial upgrading, and the construction of low-carbon and beautiful villages, forming a virtuous cycle of win-win for the government, enterprises, and farmers, thus fulfilling the social responsibility of central enterprises and achieving a win-win situation for all parties.

[0032] The digital management platform server is the core hardware carrier and computing center of the entire system.

This collaboratively completes the three-level acceptance process of "construction party-supervision party-construction party," transforming the offline, sequential acceptance process into an online, parallel process, significantly shortening the project construction to grid connection cycle.

[0035] The automatic electricity fee transfer module is configured to interface with the power grid company's settlement system and execute automatic transfer operations according to the electricity fee transfer agreement.

[0036] The operation and maintenance monitoring module is configured to communicate with the data acquisition devices at each household photovoltaic site, monitor operational data in real time, and generate operation and maintenance instructions. This module establishes a continuous communication connection with the data acquisition devices deployed on each household's rooftop via IoT technology (such as 4G / 5G, NB-IoT), receiving real-time operational data such as voltage, current, and power generation. Internally, the module analyzes the data, and once an anomaly is detected (such as inefficiency or power outage), it automatically generates an "operation and maintenance instruction" or work order containing fault information and location, and sends it to the operation and maintenance personnel's terminal.

[0037] The data analysis and decision support module is configured to analyze power generation and grid data, outputting decision recommendations for the rolling development of projects. This module is the brain and decision center of the system. It obtains power generation data from the operation and maintenance monitoring module and grid data, such as transformer capacity and renovation plans, from external grid information systems. Through built-in data mining and algorithm models, it performs correlation analysis on these two types of data, and its output decision recommendations, such as that a certain village has sufficient transformer capacity and is suitable for priority development, provide the market development team with a data-driven action guide.

[0038] The financing service interface module is configured to connect with financial institutions' systems, transmit project data required for financing in a direct leasing model, and track the financing approval status. This module is specifically responsible for connecting with financial institutions' systems. In the "direct leasing model," it transmits core project-related data (such as equipment lists, contracts, etc.) to financial institutions.

[0046] The specific usage process of this residential photovoltaic management system and method is as follows: The system and method rely on an integrated digital management platform server as the core hardware carrier. Through the collaboration and data linkage of multiple functional modules, it can realize full life cycle, one-stop digital management of household photovoltaic projects that are widely distributed in multiple administrative regions and have the characteristics of being "small, scattered and dispersed".

[0047] Its specific usage process begins with market development and application: the system receives applications from scattered farmers through an online application interface and innovatively integrates a remote acceptance sub-module, providing a unified interactive interface for construction parties, supervisors and builders, and completing the "three-level acceptance" process online and in parallel, which greatly shortens the cycle from construction to grid connection.

[0049] At the strategic decision-making and support level, the data analysis and decision support module comprehensively analyzes real-time power generation data and external power grid planning data (such as the available capacity and renovation plans of township and village-level transformers) to output data-driven decision-making suggestions, guiding the precise and rolling development of the subsequent market.

[0050] In addition, the system incorporates an innovative financing management process: it connects directly with financial institutions' systems through a financing service interface module, transmitting project equipment lists, construction progress, and revenue data in a "direct leasing model." This not only optimizes the financing review and approval process but also assists in achieving value-added tax deductions, thereby reducing costs and increasing efficiency for the project.
