What OpenSolar does
OpenSolar is a Sydney-headquartered, cloud-based solar design and sales platform founded in 2017 by Adam Pryor (CTO) and Andrew Birch (CEO). The company provides a free, end-to-end operating system for solar professionals and currently serves over 28,000 active solar installers and contractors across 185+ countries. Since inception, the platform has facilitated approximately 6 million solar system designs and $10 billion worth of solar sales. OpenSolar operates a 51-100 person organization out of its Haymarket (Sydney) headquarters and a London general office.
The platform architecture centers on AI-powered automated solar design, anchored by the proprietary Ada Design Assistant and photogrammetry-based Digital Surface Map (DSM) technology with accuracy independently validated by a leading US government agency and engineering firm PVEL. The Performance Calculation Engine is based on the trusted US National Renewable Energy Laboratory System Advisor Model. Modular components cover the full installer workflow: lead capture (PROfile, AI Lead Gen), design (Auto Design, Mounting Designer, Single Line Diagrams), sales and finance (Sales Machine Proposal, Integrated Finance, E-Signature & Payments, CashFlow), and project management (Shop & Bill of Materials, Project Management CRM, On-demand Permitting, Teams). The platform integrates Google's Solar API for global imagery coverage and connects to a 200+ partner ecosystem spanning panel manufacturers (Tesla, Trina, JinkoSolar, REC, BYD), inverters (SolarEdge, Enphase, Huawei, Sungrow, GoodWe, Fronius), mounting hardware (IronRidge, K2, SunModo, Renusol), finance lenders (Sungage, Plenti, Sunlight, EnFin, Atmos), and permitting (GreenLancer).
OpenSolar's business model is freemium at the installer layer: the core software platform is 100% free of charge to solar professionals with no license fees. Revenue is generated through a partner marketplace (Expo) where manufacturers, distributors, and finance lenders pay for access and integration at key points in the installer workflow, transaction fees on hardware orders routed through the integrated Shop and Bill of Materials, marketing services sold to manufacturers seeking access to the installer audience, and premium imagery add-ons. In October 2025 the company closed a $20 million Series A equity round led by Titanium Ventures with Google and 2150 Sustainability Fund, with proceeds directed at AI development and global expansion.
