Repowering—upgrading or replacing components—can enhance performance, extend lifespan, and ensure compliance with the latest regulations. SEPIA Energy specializes in guiding asset owners through this process, ensuring a seamless transition to a more efficient and compliant system.
Understanding Repowering
Over time, PV system components degrade at different rates. While PV modules may last for decades, inverters and other balance-of-system components often fail sooner, necessitating replacement. Repowering involves updating these elements to improve overall system performance and reliability.
If you’re planning to fix or renovate your roof, it’s the perfect opportunity to upgrade your solar installation. Combining these projects not only saves time and reduces labor costs but ensures your PV system is aligned with the latest technology and safety standards. Roof renovations provide a unique chance to enhance your solar array’s performance, integrate modern components, and comply with updated regulations like NEC rapid shutdown requirements.
Challenges and Opportunities in Repowering
Repowering presents both challenges and opportunities:
• Component Compatibility: Integrating new components with existing infrastructure requires careful planning to ensure compatibility and optimal performance.
• Regulatory Compliance: Adhering to updated safety standards, such as NEC rapid shutdown requirements, is essential to maintain system integrity and safety.
• Performance Enhancement: Upgrading components can lead to significant improvements in energy output and system efficiency.
• Financial Considerations: While repowering involves upfront costs, the long-term benefits include reduced maintenance expenses and increased energy production, leading to a favorable return on investment.
Navigating Rapid Shutdown Requirements with UL 3741
• The National Electrical Code (NEC) mandates rapid shutdown capabilities for PV systems to enhance safety during emergencies. UL 3741 offers a pathway to compliance by evaluating the entire PV system as a unit, potentially reducing the need for module-level power electronics (MLPE). This approach can simplify system design and maintenance while ensuring safety
