New platform to speed up solar rollout, supporting Australia’s 2050 Net Zero Targets–International rollout to follow

GreenSketch, the world’s first end-to-end solar design platform, has officially launched to all users in Australia following a successful beta phase. Developed by the OSW Group, GreenSketch integrates free design, product procurement, subsidy applications, and full-cycle project management into one online platform, free of charge to users. The new platform is set to revolutionise the way solar designers and installers operate.

Since its debut at All Energy 2024, Australia’s largest energy expo, GreenSketch has already empowered over 700 global installers, increasing design efficiency by 300%. The launch generated over 2,000 inquiries and expressions of interest and now the platform is available to everyone at zero cost, marking a major shift in accessibility for solar professionals.

OSW Founder and CEO Anson Zhang stated, “GreenSketch is not just an innovative design tool – it’s a breakthrough platform that integrates all of OSW’s business units. For the first time, the industry has a true end-to-end vertical solution. From pre-sales design and quoting, to product procurement and subsidy applications, to post-sales management, installers can now meet all their needs on a single platform. This marks a significant milestone for the solar sector.”

Key features & innovations

Battery-only mode: The only solution in Australia that allows users to add battery and storage options without redesigning entire systems.
Free design tools: Real-time analysis of sunlight and roof data ensures optimal layouts for every project.
End-to-end workflow: Handles pre-sales design, subsidy verification (via the GreenDeal Platform), procurement, and post-installation management – all in one place.
Automated compliance: Generates rebate documents (all energy certificates) that meet CER and IPART requirements, ensuring a smooth approval process.
Customisable pricing & proposals: Allows users to tailor their pricing and proposal templates to suit individual client needs.
100% CEC-certified equipment: Supports all brands, ensuring high-quality installations.

GreenSketch is breaking industry norms by offering a truly zero-cost solution. Users can create unlimited designs with no project caps, ensuring accessibility for businesses of all sizes. With projected annual savings in the tens of thousands of AUD, based on 2025 industry cost models, GreenSketch is redefining affordability in the solar design space.

Zhang continued: “OSW Group’s transition to a SaaS-driven model is a game-changer for the renewable energy industry. By making world-class solar design software freely available, we are accelerating Australia’s journey to Net Zero by 2050. The global solar market is evolving rapidly, and we are committed to setting the standard internationally, with upcoming rollouts planned across Europe and beyond.”

The response from beta testers has been overwhelmingly positive, with installers praising GreenSketch for its efficiency, ease of use, and game-changing features:

“GreenSketch has become an essential tool in our workflow, with over 90% of our new projects now using it. The shade analysis and proposal features offer a clear, professional presentation making it easier for end users to understand and accept.” – Dee, Director of Wonder Power
“GreenSketch is a highly valuable asset for solar and battery project development. It streamlines project design, facilitates efficient pricing input, and automates government rebate calculations.” – Solar National
“GreenSketch has been an incredible all-in-one solution for our business. It has streamlined our processes, saved us a tremendous amount of time, and significantly boosted our efficiency.” – Quinn, Solar designer of Shinehub

GreenSketch is now available with free unlimited access. Installers can register for a one-on-one onboarding session (valued at $600) before March 31 to maximise their use of the platform.
