Enact Systems
Stats That Matter
✅ Enhanced solar design accuracy with 3D shadow simulations
✅ Fully automated flat roof detection from DSM data
✅ Accelerated user engagement via immersive browser-based design
Introduction
Enact Systems, a platform powering commercial solar project design and finance, aimed to introduce
advanced 3D capabilities to improve planning accuracy. Their vision: enable solar designers to
simulate sunlight, shadows, and panel placement on any rooftop—all within a browser.
Our Role
Optellix was entrusted with the entire 3D development pipeline, including 3D rendering, geometric
analysis, and sun simulation. We built custom algorithms from the ground up to handle messy input
data and bring real-time rooftop solar modeling to life.
Scope of Engagement
- Developed algorithms to detect flat roof planes from noisy DSM data
- Created sun simulation logic to compute solar angles and shadows
- Integrated web-based interactive 3D environment
- Delivered seamless user experience for design & visualization
Client Testimonial
“Optellix’s work added tremendous visual clarity to our solar design engine. Their simulation algorithms helped us replicate real-world solar layouts with high accuracy.”
Challenges
- Noisy DSM data made plane extraction unreliable
- Realistic sun/shadow simulation required astronomical calculations
- Needed real-time rendering within browser environments
Solution
✅ Built custom plane-fitting algorithms for flat roof detection
✅ Designed virtual sun movement engine for day-long simulation
✅ Used Three.js + WebGL for browser-based visualization
✅ Delivered fully functional, interactive 3D design platform
Results
Accurate placement of solar panels with real shadow prediction
Better user understanding of solar layouts via 3D walkthroughs
100% web-based—no software installation required
Conclusion
With Optellix’s help, Enact launched a powerful, browser-native 3D solar design system. It enables
sales, engineering, and end-customers to plan smarter solar installations with confidence.
