OSW, Australia’s leading solar wholesaler and distributor, has raised $8.5 million in strategic funding from SparkEdge Capital, a Shanghai-based venture capital firm focused on technology and energy.
Established in 2013, OSW has dominated Australia’s solar sector for over a decade, maintaining the largest market share for seven consecutive years. The company has also expanded across Europe, achieving significant penetration in the Netherlands and Poland, with over 20% market share in select regions.
The newly secured capital will support expansion into priority solar markets including the United States, Mexico, Spain, and Romania. In addition, funding will accelerate development of GreenSketch, OSW’s proprietary technology platform designed to digitise and connect every stage of the clean energy value chain.
OSW Founder and CEO Anson Zhang stated, “We’ve led the Australian market for years - this investment marks a major milestone as we expand into new markets and continue developing the infrastructure needed to support the global energy transition. OSW is building an AI-driven distributed energy industry internet platform - our vision is to become the ‘Amazon’ of clean energy, delivering integrated solutions.”
Earlier in 2025, OSW launched GreenSketch, an end-to-end solar design platform positioned to transform deployment speed and efficiency. As the first zero-cost solution of its kind, GreenSketch integrates design, procurement, subsidy applications, and project management into one free-to-use interface.
Bin Wang, Partner at SparkEdge Capital, said, “We were drawn to OSW’s unique ability to combine smart software with deep sector expertise. Tools like GreenSketch are setting a new standard for clean energy delivery - and we believe OSW is positioned to lead the next wave of global solar adoption.”
With support from SparkEdge Capital, OSW is advancing AI-powered tools and automation across the solar lifecycle, including system design, compliance, credit scoring, and carbon tracking. Strategic regional partnerships will strengthen deployment efforts and enable the scaling of OSW’s clean energy infrastructure worldwide.
