This manual can be used by the owners and operation and maintenance people of PV systems. Please refer to the relevant information and requirements in this manual carefully when maintaining LONGi modules. The content of this manual includes the daily inspection of on-site modules during the operation of the PV power station, cleaning of modules, cleaning of obstructions, and handling of normal problems and other requirements and suggestions. The suggestions in this manual are to improve the safety of modules in the O&M process, and they have been tested and verified in practice.  \nAll contents in this manual are intellectual properties of LONGi which originates from long term of technical exploration and experience accumulation of LONGi.

It is recommended to visit our website regularly at [www.longi.com](www.longi.com) for the latest version of this installation manual.  \nDisclaimer  \nThis manual does not perform as any warranty terms and conditions, neither explicit description nor implications. Compensation strategy is not provided for any losses, module damaging and anyother expenses incurred which are directly caused by the module installation, operation, utilization and maintenance. LONGi Solar is neither responsible for any infringement of patent rights nor the third parties rights, which may caused by module operation and maintenance.  \n01  \nPV Module  \nPV Module Basic Knowledge and O&M Safety Notes  \n1.1 Significance ofO&M  \nIn a PV power station, PV modules are the core power generation units, which is the device that directly converts solar energy into electrical energy. The operation of PV modules has a significant impact on the power generation and revenue of the entire power station. The proper operation and maintenance methodology of solar modules could diagnose potential failures and slowdown risk expansion promptly, thus to keep the steady power generation performance within full lifetime. In addition, after each O&M operation, it is recommended to keep O&M records to provide historical data support for the long-term operation of the power station.  \n1.2 Basic Introduction to PV Modules  \nPV modules are mainly composed of eight materials: solar cells, packaging film, back sheet (mono-facial), glass, ribbon/bus bar, frame, junction box, and silicone.  \nComponents of PV Module  \nThe internal c","cbCaiq1bWmL57Lse","https://ap.wps.com/l/cbCaiq1bWmL57Lse","pdf",4456997,12,"English","# Introduction\n# PV Module Basic Knowledge and O&M Safety Notes\n## Significance of O&M\n## Basic Introduction to PV Modules\n## Q&M Safety Notes\n## Electrical Safety of PV Modules\n## Operational Safety of PV Modules\n# O&M Work Guidance for PV Modules\n## Inspection of PV Modules\n## Cleaning of PV Modules\n## Cleaning of Obstruction of PV Modules\n# Handling of Module Problems\n## Module Defect Failure\n## Non-module Defect Failure\n# Revision and Date","[{\"question\":\"Why is operation and maintenance (O\\u0026M) important for PV power stations?\",\"answer\":\"Proper O\\u0026M helps diagnose potential failures early, slows risk expansion, and maintains steady power generation over the full lifetime.
