OpenSolar Launches OS 3.0: The World’s First Free AI-Powered Solar Operating System

Posted 18 September 2025

San Francisco, September 18, 2025 – OpenSolar, the world’s leading solar software platform, today unveiled OpenSolar 3.0, a next-generation platform for solar installers globally, that combines AI-powered design, lead generation, and a fully integrated workflow — all free of charge.

Since its founding in 2019, OpenSolar has equipped more than 25,000 installers across 160+ countries with professional-grade design and sales software, offered at zero cost. OS 3.0 represents the company’s biggest release to date, reimagining the installer experience from first customer contact to system install and final payment.

“OS 3.0 is a complete rethinking of how to support solar businesses,” said Andrew Birch (“Birchy”), Co-Founder and CEO of OpenSolar. “We’ve blown up outdated and disjointed workflows and rebuilt them around speed, simplicity, and growth. And unlike every other SaaS tool out there, it’s free for installers to use it.”

Key Enhancements in OS 3.0:

  • AI-powered lead generation + system design — faster, sharper, more automated proposals
  • Electrification of everything — full customer energy profile including grid electricity, natural gas and gasoline
  • Next-gen sales experience — lifestyle presentations that help customers visualise the savings of a fully electrified home versus the cost of doing nothing
  • Integrated CRM + automated payments system — one single project management workflow, slashing software costs and hours per task, and improving cash flow with automated invoicing and accounting reconciliation
  • Hardware Shop — automatic project-based or bulk ordering built directly into the workflow
  • End-to-end operating system — covering the full solar journey, from lead to final payment

Why it matters: As solar adoption accelerates globally, professionals are often slowed by disconnected CRMs, clunky quoting tools, and time-intensive manual processes that are prone to error, especially amongst teams of people. OS 3.0 eliminates these inefficiencies, giving installers a single, integrated platform to scale their businesses more efficiently.
