Sustainable energy is the future, but residential solar installations come with unique technical and regulatory challenges. At Finulent Solutions, we specialize in designing high-power solar PV systems that maximize energy production while ensuring seamless compliance and long-term reliability.

Our latest 7.2KWp roof-mount solar PV project is a testament to our expertise in engineering, regulatory navigation, and system optimization.

Project Overview

Location: Suburban Residential Property
System Size: 7.2 KWp DC
Annual Energy Production: 9,343 kWh
Roof Type & Area: Metal trapezoidal roof, 2,485 sq. ft.
Performance Ratio (PR): 84.19%
Solar Irradiance: 1,608 kWh/m²/year

Challenges & Key Considerations

• Structural Constraints: The metal trapezoidal roof (18° pitch) required a non-invasive mounting solution to avoid a roof penetration.
• Shading & Sun Exposure: Achieving 98% solar access was critical for maximizing efficiency.
• Regulatory Compliance: Ensuring compliance with NEC 705.12(B)(2)(3)(b) while securing timely approvals.
• Optimized Electrical Design: Maintaining an efficient DC-AC ratio (~1.44) and ensuring safe grid interconnection.
• AC Disconnect Placement: Installing within 10 feet of the utility meter as per NEC 230.85 and utility regulations for
  1. Emergency Access – Quick power shutdown for safety.
  2. Code Compliance – NEC requires an external disconnect.
  3. Utility Standards – Ensures easy service disconnection.
  
  This placement enhances safety, accessibility, and regulatory compliance.
  

Innovative Solutions Implemented

• Advanced Non-Penetrative Mounting System
  We deployed the S-5! ProteaBracket, is a clamp-based, non-invasive mounting system that attaches directly to the roof seams, ensuring zero damage to waterproofing.
• Smart Solar Design & Software Integration
  Aurora Solar: Detailed shading analysis, solar irradiance mapping, and annual yield simulation.
  AutoCAD: Precision array layouts and electrical schematics for optimized panel placement.
• High-Efficiency System Components
  Solar Modules: 18 x Hanwha QCELLS Q.PEAK DUO BLK-ML-G10+ 400W panels (20.4% efficiency)
  Inverter: SolarEdge SE5000H-US RGM (99.2% efficiency, module-level monitoring, rapid shutdown).
  Power Optimizers: SolarEdge P401, ensuring independent module-level optimization for maximum energy yield.
  Interconnection: 30A 2P PV breaker in 200A/200A MSP configuration, ensuring safe NEC-compliant grid integration.
• Proactive Regulatory Compliance & Grid Interconnection
  Comprehensive permit plans were prepared, ensuring a smooth approval process and faster utility interconnection.
• Strategic AC Disconnect Placement
  Following best practices, the PV AC disconnect was installed within 10 feet of the utility meter, ensuring:
  1. Easy emergency access
  2. Compliance with NEC regulations
  3. Minimized energy losses

Results & Business Impact

• 84.19% performance ratio – maximizing homeowner savings and ROI.
• Roof integrity preserved – no penetrations, maintaining structural warranty.
• Full NEC compliance – ensuring safe, long-term grid integration.
• Project completed on schedule – all permits secured efficiently.
