Shoals teams with PCL for Maryvale solar-plus-storage project build delivery

• Shoals Technologies Group will partner with PCL Construction on the 243-MWp Maryvale solar-storage project in New South Wales, combining EBOS expertise with utility-scale delivery

Shoals Technologies Group has been selected to work alongside PCL Construction on the Maryvale solar-plus-storage project in New South Wales, a 243-MWp installation that will pair utility-scale photovoltaics with battery storage. The collaboration brings together Shoals’ electrical balance-of-system (EBOS) hardware and PCL’s large-project delivery capabilities—an increasingly common partnership model as Australian developers seek reliability, speed, and cost control.

At the heart of Shoals’ value proposition is a shift from traditional field wiring to pre-engineered, plug-and-play harnesses, junction boxes, and above-ground raceway systems. By reducing terminations and trenching, EBOS packages aim to cut installation hours, shrink scrap and rework, and improve quality through factory-controlled assemblies. Those efficiency gains add up on a project of Maryvale’s scale, where thousands of string connections and combiner points must be installed, tested, and documented to exacting standards.

For PCL, integrating EBOS early allows mechanical, civil, and electrical scopes to be sequenced more tightly. Rack installation, cable routing, inverter placement, and battery yard construction can proceed in coordinated workfronts, minimizing downtime and avoiding the bottlenecks that often emerge near energization. Close attention will also be paid to grid compliance, with protection settings, ride-through behavior, and plant-level controls tuned to local network requirements.

The addition of storage is central to the project’s value. Batteries can shift daytime solar output into evening peaks, firm the plant’s production profile, and provide essential grid services—ramping, contingency reserves, and frequency support—when dispatched by the operator. Co-location consolidates interconnection and reduces round-trip losses between the PV field and the battery, improving overall economics.

Australia’s strong solar resource and evolving market design favor hybrid assets that deliver both low-cost energy and dispatchable capacity. With Shoals’ standardized EBOS and PCL’s utility-scale execution, Maryvale is positioned to move efficiently from construction to commercial operations while setting a template for future solar-storage builds in the region.
