Choose PVStream for:

High-Velocity Design API
Institutional Verdict
Automation-First Pivot
A high-fidelity peer swap: Switch to PVstream if your bottleneck is rapid design automation and you need a high-velocity, sales-centric intake engine.
Strategic Fit: High-Velocity Design API requiring engineering precision and physical-world accuracy through deep technical or hardware-specific data.
The Strategy

PVstream is the engineering automation champion for high-velocity residential firms, immediately followed by its fatal flaw: a total dependency on data hygiene. While it provides the only real-time, permit-ready plan set engine with engineering-grade electrical accuracy, the manual administrative overhead of managing AHJ fragmentation and the scaling limitation of CRM data-parity creates a terminal operational friction for teams that lack a centralized rules-engine lead.

Integration: Best paired with Enerflo (CRM/Ops) to bridge high-velocity lead intake with automated, permit-ready engineering sets.

Choose Solargraf for:

Integrated EPC Sales Engine
Institutional Verdict
All-in-One Sales Speed
Switch to Solargraf for an unified design-to-financing workflow that prioritizes rapid residential proposal generation and native dealer-fee modeling.
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
PVStream ✦
› The Auto-Layout Suboptimality is a persistent technical liability.
› While the platform generates plan sets in seconds, the high-speed algorithm often produces suboptimal DC-string routing and conductor sizing unless your AHJ-specific setback rules are meticulously pre-configured.
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
PVStream
› Your lead-to-design velocity hits a scaling limitation at 30 projects/mo.
› PVstream's efficacy relies entirely on the absolute roof-coordinate metadata pushed from your CRM.
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
PVStream ✦
› Do not deploy PVstream if you are a Stage 1 installer without a standardized CRM-to-Design data flow.
› The manual administrative overhead of manually correcting auto-generated plan sets for unique AHJ requirements will consume the 40% cost-savings the tool promises.
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.
