Introducing Resilient Solar Photovoltaic Design to Ensure Long-Term Stable Operations under Extreme Climate Conditions

Global climate change has made extreme weather events increasingly frequent, with strong winds and heavy rainfall posing severe challenges to renewable energy facilities. To ensure the reliability of green energy facilities, the ECOVE team recognizes that site resilience must be planned across the entire life cycle, with a focus on two critical dimensions: site selection and planning, and operations and maintenance management. By adopting resilient engineering designs that exceed regulatory standards, ECOVE ensures that solar photovoltaic sites can maintain structural integrity when exposed to extreme climate events and sustain high availability and long-term stable power generation over an operating period of more than 20 years. ECOVE has launched a comprehensive solar photovoltaic resilience design and O&M program, covering the following four key dimensions:
　

Precise Risk Quantification and Climate-Resilient Protection Design

During the site selection and design stages, ECOVE takes proactive measures for coastal or highwind- speed areas by upgrading structural windresistance design to two levels above regulatory requirements, such as from 37.5 m/s to 47.5 m/s. For heavy rainfall risks, ECOVE plans in advance for elevated foundations, upgraded drainage systems, and detention design. For coastal salt damage, ECOVE selects higher-grade corrosion-resistant aluminum-magnesium-zinc coated steel and electrical panel equipment made with 316 stainless steel, reducing the risk of flooding and corrosionrelated failures.
　

Strengthening Ground Conditions and Structural Foundation Safety

Through rigorous soil boring and geotechnical analysis, ECOVE optimizes foundation types based on geological conditions, such as liquefaction risk or sof t ground conditions, and adopts a three-support structural design to enhance module stability. At the planning stage, ECOVE also introduces external reviews by third-party certification bodies such as SGS to objectively verify structural risks, wind loads, and material weatherability, signif icantly enhancing the credibility and disaster resistance of the design solution.
　

Implementing Preventive Inspections and Rapid Post-Disaster Recovery

Before each typhoon or heavy rainfall season, ECOVE conducts s tandardized resi l ienceoriented preventive inspections, including comprehensive retesting of structural torque, drainage system cleaning, and reinforcement of electrical equipment protection. In the event of a natural disaster, the team is equipped with a rapid inspection mechanism, using drone aerial photography and thermal imaging to quickly identify damage. The SCADA system is also used to compare power generation trends and eliminate hidden risks, enabling safe power restoration in the shortest possible time.
　

Promoting Smart O&M and Life-Cycle Management

ECOVE is upgrading conventional monitoring into a smart platform with AI-enabled early warning capabilities. AI models are used to detect the rate of module degradation and estimate the impact of wind pressure on mounting structures, enabling early warning and predictive maintenance. In response to operating challenges spanning 20 years, ECOVE is deepening its cross-generation equipment replacement and system-matching capabilities, while improving spare parts inventory management. Even when original modules or inverters are discontinued, the team can accurately calculate electrical parameters and introduce compatible next-generation equipment to seamlessly maintain power generation performance.
　

Results and Outlook

In the era of extreme climate events, ECOVE has successfully upgraded the construction standards for solar energy sites from simply being able to generate power to asset protection that enables long-term stable power generation, through a dual-track framework of front-end disaster prevention and back-end long-term stability. Looking ahead, CTCI Group and the ECOVE team will continue embedding resilience thinking into every aspect of green engineering, fulfilling the mission of serving as a guardian of the Earth’s sustainability, safeguarding the long-term value of green energy, and building a stable and trustworthy foundation for a sustainable society.
