How Fluxiss Designed a 15kW Elevated Residential Solar PV System with Zero Shading Loss

This project involved a 15kW residential elevated solar PV system, designed for a home where roof height, airflow, and shading were major concerns. The client wanted maximum energy output without compromising structure safety or electrical compliance.

We designed and simulated the complete system using HelioScope and PVsyst, which allowed us to test performance before installation and reduce future risks.

System Configuration

• 26 × Jinko 580W solar panels
• 15kW Inverex Nitrox 3-Phase inverter
• South-facing orientation
• Elevated steel structure with variable height

   

Project Challenge: Elevated Structure, Tilt Optimization & Zero Shading

Designing an elevated residential solar system is not the same as a standard rooftop setup. The main challenges were:

• Creating a safe elevated steel structure between 7 ft and 10 ft
• Selecting a tilt angle (5.4°) that balances wind load and energy yield
• Avoiding shading from nearby structures
• Managing DC and AC protection in a limited residential electrical space

Our engineering team had to ensure zero shading loss, correct cable sizing, and safe electrical isolation while keeping the design practical for real installation.

Engineering Solution by Fluxiss

Fluxiss delivered a complete solar PV design and calculation package, including:

• Detailed HelioScope and PVsyst simulations
• Elevated structure layout with load consideration
• Full electrical single-line diagram
• DC disconnect integration
• 4-Pole circuit breaker configuration
• System loss analysis and performance ratio check

Every design decision was based on site conditions, not assumptions.

Project Outcome: Verified Performance & Clean Energy Output

The final design achieved strong and verified results:

• Annual Energy Production: 23.20 MWh
• Performance Ratio: 77.4%
• Shading Losses: 0.0%
