Strategic Success Analysis

The Solargraf Moat
Choose SolarGraf over standalone design tools if you require a fully integrated Enphase-native design experience with high-conversion consumer proposals. Its deep hardware-software synergy is unmatched for residential installers.
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 Solargraf to Sunnova requires adjusting CAD-level shading accuracy tolerances and recalibrating NBT ROI modeling for NEM 3.0 compliance.
