Aurora Solar vs OpenSolar Strategies

OpenSolar’s free tier is less a free software giveaway than a different way to get paid. Instead of charging upfront for every seat or project, it uses the design tool to pull small installers into a transaction network where financing, hardware ordering, and paid connectors create revenue, while Aurora charges directly for accuracy, workflow depth, and higher value project work used by larger teams.

• OpenSolar states that the core app remains free, and explains that partners like hardware makers and finance providers fund the platform. Its hardware ordering flow with Solar Outlet gives it a share of order value, making monetization look more like a marketplace than a pure SaaS subscription.

• That model fits smaller residential installers. A solo rep can design a system, show financing options in a proposal, and place equipment orders without committing to software spend first. OpenSolar’s newer Finance Marketplace pushes further in this direction by embedding lender choice directly into the customer proposal flow.

• Aurora monetizes in the opposite direction. It sells paid plans and credit based usage for design work and premium features like AI site models, e-signature, and third party model requests. That pricing structure matches teams that care more about design precision, permissions, and standardized workflows than zero cost entry.

The market is likely to split more clearly in two. Free, partner funded tools will keep winning the long tail of small installers, while paid systems with deeper design and operations tooling will consolidate larger firms. The next battleground is turning solar software from a design app into the operating layer for financing, procurement, permitting, and project execution.
