In a major boost for clean energy innovation, OpenSolar, the Australian-founded renewable software platform, has raised US$20 million (A$30 million) to advance its artificial intelligence capabilities and expand its global footprint. The latest funding round reinforces the company’s mission to make solar energy adoption faster, more efficient, and universally accessible, while cementing its position as one of the most influential software providers in the global solar ecosystem. The investment round drew continued backing from Titanium Ventures (formerly Telstra Ventures), alongside climate-focused investor 2150 Sustainability Fund and technology partner Google. With this raise, OpenSolar’s total funding now surpasses US$45 million (A$68 million) since its inception in 2017 marking a new chapter in its growth trajectory as it scales to meet accelerating global demand for renewable energy solutions.

A Digital Backbone for the Global Solar Economy

Founded in Sydney by Adam Pryor and Andrew “Birchy” Birch, OpenSolar has emerged as a foundational digital platform for the solar industry. It offers a free-to-use software suite that enables solar installers to design, sell, and manage solar systems through an integrated ecosystem that combines precision engineering tools with business management capabilities. Powered by Google’s Solar API and OpenSolar’s proprietary AI engine, the platform supports a wide range of functions from advanced system modeling and 3D visualization to proposal generation, financing integration, payment processing, and hardware ordering. Today, more than 25,000 installer businesses across 160 countries use OpenSolar’s technology to serve residential, commercial, and industrial markets. This interconnected digital network links installers with hardware suppliers, financing partners, and service providers, helping to streamline workflows and reduce soft costs that often make up a significant portion of solar installation expenses. By optimizing every step of the customer journey, OpenSolar is transforming how solar energy is designed, sold, and delivered.

Advancing Artificial Intelligence to Scale Solar Adoption

The company’s newest release, OpenSolar 3.0, represents a leap forward in applying AI to clean energy deployment. The upgraded platform leverages advanced algorithms to improve design accuracy, automate proposals, and optimize system layouts, allowing contractors to deliver precise, cost-effective solar solutions in record time. CEO Andrew Birch emphasized that this AI innovation is not just about operational efficiency, it’s about accelerating the world’s transition to renewable energy.

“The ability for any contractor to access world-class software and imagery for free is supporting the rapid transition to low-cost clean energy,” Birch said.

OpenSolar’s AI engine draws on millions of prior solar designs and real-world performance data to make smarter recommendations, reducing manual design work and cutting the time from customer inquiry to system proposal by up to 70%. These capabilities are expected to play a pivotal role in expanding solar access in developing markets where installer expertise and capital are often limited.

Global Impact and Industry Transformation

Since its founding, OpenSolar’s platform has facilitated the creation of over six million solar system designs, translating into approximately US$10 billion in solar sales globally. Each new installation contributes to the company’s broader goal: enabling 50% of global energy generation from renewables by 2035. By democratizing access to advanced solar technology, OpenSolar lowers entry barriers for smaller installation businesses while enhancing transparency and competitiveness across the sector. This aligns closely with global energy transition objectives set by the International Renewable Energy Agency (IRENA) and supports the decarbonization goals of major economies striving for net-zero emissions by mid-century. Investors such as Titanium Ventures and Google view OpenSolar’s model as a scalable solution for climate impact bridging the gap between high-level energy policy and on-the-ground deployment. As AI and digitalization reshape the renewable energy landscape, OpenSolar is positioning itself as the software backbone that can turn policy ambition into measurable progress.

A Future Built on Open Access and AI Intelligence

OpenSolar’s business model offering its core software free to users while generating revenue through partnerships with hardware, finance, and service providers has proven instrumental in expanding its global reach. The company plans to use the new funding to double down on AI development, broaden its partner ecosystem, and enter additional high-growth markets across Asia, Europe, and North America. Birch believes that the key to accelerating the global clean energy transition lies in empowering the professionals who make it happen every day.

“When you give installers the tools to design and deliver solar faster and more accurately, you don’t just make their businesses better, you make the planet better,” he said.
