✦ 2026 OpenSolar API Tax Calculator
OpenSolar transitioned to tiered API pricing on April 18, 2026. Use this to audit your monthly OpEx impact.
Note: Calculation based on $1.50 USD (Base Sync) or $2.20 USD (Raw Data) per project. Does not include Premium Imagery ($6/image) or lead purchase costs.
Technical Tier Breakdown
OpenSolar fees are triggered by specific operational events. These represent mandatory overhead for syncing data to your CRM or Ops tools—a cost formerly absorbed by the platform but now shifted to the installer's P&L.
Core CRM Sync
~$1.50 USD / projectTriggered whenever a project is created if API syncing is enabled for your CRM (HubSpot, GHL, etc.).
Raw Design Data
~$2.20 USD / projectRequired if you pull full shading data, system specs, or compressed designs into external ops tools.
Accounting Connectors
~$32.00 USD / monthA flat monthly fee for using the native QuickBooks or Xero accounting integrations.
The "Safe Harbor" Alternatives
If your project volume makes OpenSolar's API fees untenable, these platforms offer predictable, inclusive cost models for high-scale teams.
| Institutional Alternative | Monthly Subscription | API Access Fees | Strategic Value |
|---|---|---|---|
| Aurora Solar | ~$220/user | Included | The Institutional Standard. Predictable seat-based pricing that eliminates the Usage-Fee Friction for high-volume engineering teams. |
| SolarGraf | ~$100/user | Included | Hard-coded design and financing workflows. Ideal for Stage 2 teams avoiding the Administrative Overhead of managing per-project API taxes. |
| Scoop Solar | Project Based | $0 | Operations-first logic. Zero Data Tax for bi-directional syncing between your design engine and field ops. |
Note on 'Included' Costs: While these platforms do not charge a per-project API fees, access to their API is typically by subscription tier (e.g., Enterprise) or project credit bundles. Your actual OpEx will depend on your pre-negotiated contract and seat count.
The Auditor's Verdict
At project volumes exceeding 40 installs per month, the tiered API model creates a Project Velocity Delay. Teams must either pay the "tax" or absorb the Shadow Labor of manual data re-entry, both of which erode net margins at scale.
High-volume Stage 4 EPCs should not operate on a per-project API model. The cumulative cost of Tier 1 and Tier 2 syncs will eventually exceed the seat-cost of an Institutional Core platform like Aurora or SolarGraf.
Disabling API sync to save costs is a False Economy. You will simply pay a full-time admin to copy-paste project specs, creating an invisible Administrative Overhead that is 5x more expensive than the API fee.
