Strategic Success Analysis

The Arka 360 Moat
Choose Arka-360 over legacy design engines if you need a truly unified sales-to-finance frontend with modern, high-speed 3D rendering. It provides a more cohesive 'all-in-one' proposal experience than fragmented tool stacks.
The Sunnova Moat
Sunnova is the 'Institutional TPO Standard' for high-volume firms who value capital stability and long-term asset management. In 2026, it is the preferred choice for Stage 3-4 firms who need a bankable, document-compliant financing rail that can support massive project fleets.

Operational Friction: Switching from Arka 360 to Sunnova requires adjusting CAD-level shading accuracy tolerances and recalibrating NBT ROI modeling for NEM 3.0 compliance.
