One Stop Warehouse (OSW), a solar wholesaler and distributor, has secured A$8.5 million (~$5.5 million) in strategic funding from SparkEdge Capital, a venture capital firm based in Shanghai focused on the energy and technology sectors.
The funding will be used to support the company in its next phase of international growth in key solar markets, including the U.S., Mexico, Spain, and Romania. Currently, apart from Australia, the company has built its presence across Europe, especially in the Netherlands and Poland.
This funding is also said to accelerate the rollout of GreenSketch, the company’s end-to-end solar design platform that integrates design, procurement, subsidy applications, and project management into a single, free-to-use interface.
OSW Founder 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.”
With the backing of SparkEdge Capital, OSW aims to embed AI tools and automation across the solar process—from design and compliance to credit scoring and carbon tracking. Regional partnerships are expected to aid local deployment and scale OSW’s global clean energy infrastructure.
According to Mercom’s 1H 2025 Solar Funding and M&A report, VC funding activity decreased 7% year-over-year, with $2.5 billion raised in 32 deals in 1H 2025 compared to $2.7 billion from 29 deals in the first half of 2024.
