Wirsol

What Wirsol does

Wirsol is an Australian utility-scale solar and energy storage developer, headquartered in Manly Vale, with 11-50 employees and operations tracing back to 2017. The firm develops, constructs, and operates utility-scale solar photovoltaic farms using single axis tracking technology to maximize generation, and owns lithium ion battery storage assets including what is described as Australia's second largest lithium ion battery and the first integrated renewables and storage facility in Victoria. Its operating portfolio comprises at least nine named projects across Queensland, Victoria, and New South Wales, including Whitsunday, Maryvale Solar + Storage, Glenrowan West, Wemen, Gannawarra Solar Farm, Gannawarra Energy Storage System, Clermont, Hamilton, and Barnawartha Solar + Storage.

Wirsol's service offering spans the full project lifecycle: Project Development from inception through design, approval, and construction; Construction Management; long-term Asset Management; and Operations & Maintenance. The company derives revenue from four streams: one-time project development and construction fees, recurring asset management fees, recurring O&M contracts, and recurring power generation sales to the national electricity network. The firm leverages engineering expertise from more than 1.2 Gigawatts of utility-scale solar developed across its international portfolio.

Wirsol's go-to-market is direct enterprise engagement with institutional investors, utilities, and grid operators for project development, construction, and long-term asset management contracts. It supplements this with a landowner partnership program for site access and a service provider network for project delivery. The customer base is structurally concentrated in the national grid as the primary offtaker of generated power, with institutional investors as capital partners. Pricing is not publicly disclosed, consistent with B2B utility-scale contracting.
