SECTION 1: The Nine Pillars of OpenSolar's Backend Brain

At its heart, OpenSolar is a symphony of nine distinct backend engines, each playing a crucial role in orchestrating your solar projects. Understanding these engines individually is key because they fire in a specific sequence, much like a well-rehearsed performance. Let's introduce our star players:

  1. Authentication Layer: This is your gatekeeper, ensuring secure access and verifying user identities. It's the first line of defense, making sure only the right people can access the right information.
  2. Org + Role Resolution Engine: This engine is all about context. It defines your organization's unique settings, user roles, and their associated permissions, creating a personalized environment for your business.
  3. Project Context Engine: Once authenticated and within your organization, this engine establishes the foundation for each project, pulling in all relevant data and settings specific to that particular endeavor.
  4. Auto-Apply Engine: This is where the magic of automation truly begins. It proactively applies pricing schemes, default components, incentives, and other crucial settings without requiring manual intervention, saving precious time.
  5. Imagery & Mapping Engine: Essential for accurate system design, this engine integrates with services like Nearmap to provide detailed aerial imagery, roof geometry, and mapping data.
  6. Auto-Design Engine: Leveraging the imagery and mapping data, this engine can automatically generate initial solar system designs, including panel layouts, inverter placement, and production estimates.
  7. Pricing Engine: This is the financial powerhouse, meticulously calculating project costs based on chosen components, add-ons, taxes, and dealer fees. It ensures accurate and transparent pricing for every proposal.
  8. Workflow Automation Engine: This engine manages the project's journey through its lifecycle, triggering tasks, notifications, and stage transitions based on predefined rules and events.
  9. Proposal + Contract Engine: The final piece of the puzzle, this engine generates compelling proposals and legally binding contracts, pulling all necessary data and presenting it in a professional format.

Familiarizing yourself with each of these engines and their sequential interactions is paramount for anyone looking to master OpenSolar's capabilities. It's the difference between simply using a tool and truly understanding how to wield its full power.

SECTION 2: The Gateway – Authentication and Organization Resolution

Every interaction within OpenSolar begins with a robust authentication process. This isn't just about logging in; it's about establishing trust and defining the boundaries of what each user can see and do. When you or your team members access OpenSolar, the system validates API tokens, ensuring that only authorized personnel can proceed. This foundational step is crucial for security and data integrity. Once authenticated, the Org + Role Resolution Engine springs into action, loading a wealth of critical information that dictates your user experience and operational capabilities. This includes:

  • User Identity: Your unique user.id and user.email are confirmed.
  • Organizational Context: The org_id links you to your specific company settings, ensuring all data and configurations are relevant to your business.
  • Roles and Permissions: Your assigned roles[] are loaded, and crucially, the engine maps out the specific permissions per module you possess. This granular control is what allows for tailored user experiences, preventing unauthorized access or modifications.
  • Feature Flags and Experiments: These allow for controlled rollout of new features or A/B testing within your organization.
  • External Licenses and Libraries: Information regarding your Nearmap license, Component libraries (the specific solar equipment available to you), Pricing schemes, and Adders (additional costs for specific components or services) are all loaded here.
  • Business Rules: Settings like Dealer fee rules, Org sharing chains (for multi-branch organizations), and Tax blocks are configured and made accessible.

To illustrate, consider an example org block:

{
  "org_id": 101611,
  "country": "US",
  "currency_code": "USD",
  "utility_tariffs_enabled": true,
  "imagery_provider": "Nearmap",
  "sales_tax": 8.25%
}

This block immediately tells OpenSolar essential details about your business's operational context. Furthermore, the Role example (Admin) demonstrates how permissions are structured:

{
  "id": 367750,
  "role": "Admin",
  "permissions": { "view":1, "create":1, "edit":1, "delete":1 }
}

These permissions are not just abstract settings; they have tangible impacts. They directly determine the behavior of the design tool, the ability to edit contracts, the flexibility in modifying proposal templates, access rights to adder pricing, and even override capabilities within automated workflows. Understanding your organization's configuration and your role's permissions is the bedrock upon which all other OpenSolar functionalities are built. It's the key to unlocking the platform's full potential while maintaining security and operational integrity.

SECTION 3: Kicking Off a Project: The Backend Flow of Creation

So, you've got a new lead, and it's time to get them into the system. The journey of a solar project within OpenSolar begins with its creation, a process that can be initiated through various channels: directly via the user interface (UI), through an integrated lead form, or programmatically via an API call. Regardless of the entry point, the backend initiates a standardized procedure to generate a base project object. This object serves as the initial container for all the information that will be associated with the project throughout its lifecycle. The POST /api/projects/ endpoint is typically the trigger for this process.

Upon creation, the backend meticulously generates a foundational project object. This object is populated with essential identifiers and statuses, setting the stage for subsequent operations. The core components of this initial project object include:

  • id: A unique identifier for the project.
  • org_id: Linking the project back to your organization.
  • address: Details about the project location, including latitude (lat) and longitude (lng).
  • workflow_stage: The current position of the project within your defined sales pipeline.
  • project_status: A more general status indicator for the project.
  • solar_design_set: An array that will eventually hold the details of the solar system design(s).
  • contacts: Information about the homeowner and other relevant parties.
  • assigned_users: Team members responsible for the project.
  • financials: An object that will store all cost and payment-related data.
  • activities: A log of actions and events related to the project.
  • created_date and modified_date: Timestamps for tracking the project's history.

This initial creation step is critical because it doesn't just create a placeholder; it immediately sets in motion the next vital component of the OpenSolar backend process. Right after creation, OpenSolar triggers the Auto-Apply Engine. This is not a passive process; it's the FIRST heavy backend engine that fires, kicking off a cascade of automated actions designed to pre-populate and configure the project based on your established business rules and defaults. This proactive approach ensures that from the very first interaction, the project is already moving down a path of efficient, automated setup, minimizing manual data entry and potential errors. Understanding this immediate post-creation trigger is crucial for appreciating how OpenSolar streamlines the initial stages of project management and sets the foundation for the complex calculations and designs that follow.

SECTION 4: The Power of Automation: Unpacking the Auto-Apply Engine

As we’ve seen, the Auto-Apply Engine is the first heavyweight player to enter the scene immediately after a project is created. Its primary function is to inject intelligence and automation into the nascent project, ensuring that essential configurations are set up correctly from the outset. This engine is designed to process a variety of crucial data points and apply them automatically, significantly reducing the need for manual configuration later in the sales cycle. The key elements that the Auto-Apply Engine processes include:

  • Pricing Schemes: It identifies and applies the default pricing scheme set for your organization. This ensures that all projects start with a consistent pricing methodology.
  • Component Defaults: If you have specific default components (like certain panel brands or inverter models) pre-selected for your organization, this engine ensures they are populated.
  • Incentives: Applicable government or utility incentives that are set to auto-apply will be identified and included.
  • Adders with Auto-Apply Rules: While many adders might require manual selection, those configured with auto_apply_enabled: true will be automatically added to the project at this stage.
  • Tariff Assignment: Default utility tariff information relevant to the project's location can be automatically assigned.
  • Equipment Defaults: Similar to component defaults, this ensures that standard equipment configurations are applied.
  • Design Templates: Pre-defined design templates can be applied to kickstart the design process.
  • Tax Profiles: The relevant tax rules and rates for the project's location are automatically applied.

The goal here is to establish a baseline for the project that reflects your organization's standard operating procedures and pricing strategies. For instance, your organization might have a primary pricing scheme that is almost always used. The system would identify this scheme and apply it automatically. Consider the example of a pricing scheme:

ID: 190782 – “Price Per Watt” with auto_apply_enabled: true.

This tells OpenSolar to immediately adopt this
