Choose Arka 360 for:

Unified Sales-to-Finance Frontend
Institutional Verdict
Visual Fidelity Swap
A specialized category deep-dive: Switch to Arka for superior 3D visual fidelity and consumer-facing design speed that prioritizes sales aesthetics.
Strategic Fit: LIDAR-Native Design Engine serving as the connective tissue and operating system for data flows across an unified suite or middleware.
The Strategy

Arka 360 is the modern benchmark for unified sales-to-finance design, immediately followed by its fatal flaw: a total dependency on client-side hardware. While it provides a more cohesive unified proposal experience than fragmented legacy stacks, the manual administrative overhead of managing GPU latency in the field and the scaling limitation of component-library standardization creates a terminal operational friction for firms that lack a dedicated design-ops lead.

Integration: Best paired with SalesRabbit (Sales) to bridge visually-driven field canvassing with modern, high-speed 3D proposals.

Choose Solargraf for:

Integrated EPC Sales Engine
Institutional Verdict
All-in-One Sales Speed
Switch to Solargraf for an unified design-to-financing workflow with more integrated dealer-fee modeling for residential projects.
Strategic Fit: Integrated EPC Sales Engine acting as a high-velocity point solution for single-task efficiency to reduce friction in the top-of-funnel or specific workflows.
The Strategy

Solargraf dominates the integrated sales experience for Enphase-aligned installers, delivering rapid 3D designs and signature-ready contracts in a single cloud-native tool. However, because its advanced data rails are tethered to premium Enphase Enlighten tiers, your operations manager will absorb massive manual administrative overhead either paying up to $999/month for API access or manually re-entering project data into your backend monitoring stack.

Integration: Best paired with ServiceTitan (Ops) for a high-velocity residential sales stack.

Side-by-Side Matchup

Direct qualitative benchmarking of Technical Red Flags and Maturity Walls.

The Technical Ceiling

SYSTEM CONSTRAINT
Arka 360 ✦
› The GPU Latency Void is a persistent technical drag.
› High-fidelity LIDAR rendering in Arka requires a modern GPU-accelerated browser environment to maintain sub-second UI responsiveness.
Solargraf
› API access is strictly gated behind expensive Enphase Enlighten tiers.
› For Stage 2 installers trying to automate their design-to-monitoring data flow, this creates a high financial barrier where your system data is effectively siloed unless you pay the integration complexity for full programmatic scaling.

The Maturity Wall

SCALABILITY LIMIT
Arka 360 ✦
› Your design velocity hits a scaling limitation if you haven't standardized your component-library.
› While Arka provides high-speed 3D rendering, the manual administrative overhead of manually selecting and verifying inverter/module parity for every proposal will consume your entire speed advantage.
Solargraf
› The primary scaling wall is the integration complexity.
› While the base cost of $129/user is competitive, the hidden costs of premium API access for high-volume automation will cannibalize your margins as you scale.

The Deep-Dive Audit

TECHNICAL DEPTH
Arka 360
› Do not deploy Arka 360 if you are an institutional EPC managing MW-scale portfolios.
› The manual administrative overhead of managing its GPU-heavy UI and the lack of deep engineering-grade civil constraints will destroy the margin on complex utility projects.
Solargraf
› Do not deploy Solargraf if your business model relies on a diversified hardware mix involving SolarEdge or SMA.
› The platform's ecosystem lock-in means that designing with third-party hardware often results in reduced data fidelity and manual intervention in the financing-bridge, effectively neutralizing its primary speed advantage.

Lumen Economic Verdict
Verified 2026 Audit
Lumen Audit Note
The Visual Fidelity Surcharge. While basic 3D modeling is included, high-res LIDAR/Nearmap data are often passthrough costs. Furthermore, if you want permit-ready 3D exports, you are forced to upgrade to the Premium tier.
Operational Impact
Cuts Pre-Sales Design Time to under 10 minutes for field reps, but creates a bottleneck at the engineering handoff if you are on the Basic plan.
Hard Margin Benefit
Provides high-end 3D visual sales tools at a lower entry price than Aurora, protecting your marketing margins—if your close rate is high enough to absorb the per-project imagery fees.

Verified 2026 Audit
Lumen Audit Note
The Platform Integration Premium Pricing includes integrated LIDAR and basic financing modeling, but advanced per-project Nearmap imagery remains a passthrough cost that is often hidden in the base subscription.
Operational Impact
Combines design and financing into a single workflow, but creates Data Lock-in that makes pivoting to a specialized Specialist CRM or Finance rail difficult at the Stage 3 maturity level.
Hard Margin Benefit
Protects sales margins for Stage 2-3 residential installers by providing a verified, end-to-end proposal rail with zero Integration Latency between design and contract.
