With the rapid expansion of distributed photovoltaic systems, we hereby issue a full-lifecycle safety and operations-and-maintenance initiative to ensure the industry’s long-term, healthy development and safeguard the fundamental interests of system owners. Safety is the absolute cornerstone of 25 years of stable returns for PV systems—and there is simply no room for complacency.

01. Design and installation are the root: Choose professionals to eliminate potential hazards.

Professional qualifications: Priority shall be given to professional organizations that possess power engineering design qualifications and a license for the installation (repair and testing) of power facilities.

Structural Safety: Rigorously calculate roof loads and design appropriate support structures and foundations to ensure wind and snow resistance.

Electrical safety: Standardize the installation of DC cables, provide clear signage, and ensure adequate electrical clearance and reliable grounding.

Fire safety: A thermal clearance is provided between the components and the roof to prevent cable friction, and flame-retardant materials are used.

02. Inspection safety is key: proactive prevention is better than reactive remediation.

Regular inspections: It is recommended to conduct a comprehensive inspection every six months to one year, covering connectors, cables, support brackets, and fasteners, among other components.

Intelligent Monitoring: Fully leverage the monitoring platform to track power generation data in real time; abnormal fluctuations may serve as early indicators of potential equipment failures.

Cleaning and Maintenance: Conducted by qualified professionals to prevent hidden cracks in modules or electrical shock hazards caused by improper cleaning.

03. Emergency Response is the Bottom Line: Public Education and Preparedness Prevent Problems

Clearly identify the risks: Photovoltaic systems remain energized under illumination, with particular vigilance required regarding the risk of high DC voltage.

Well-versed in procedures: Property owners and property management staff are familiar with the emergency shutdown procedure and the fire emergency response plan.

Work Procedures: All maintenance work must be performed by qualified personnel who have de-energized the equipment in accordance with strict procedures and are fully equipped with personal protective equipment (PPE).
