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 OpenSolar Moat
Choose OpenSolar over paid SaaS design browsers if you are a Stage 1-2 installer prioritizing zero-cost overhead and partner-driven hardware integrations. It is the superior choice for scaling teams that want the technical depth of Aurora without the SaaS monthly subscription seat-tax.

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