Ground-mounted,
grid-connected, built to last

The economics of utility-scale solar in Australia are now structurally competitive with every other form of new electricity generation. Falling panel and tracker costs, a maturing NEM market and strong corporate demand for power purchase agreements have created a genuine development pipeline, but the difference between a project that reaches financial close and one that stalls is almost always execution: grid connection timing, land certainty, equipment procurement and construction quality. Zenith brings the engineering and delivery discipline to navigate all four.

We operate as a full EPC contractor, which means a single contract and a single point of accountability from first sod to final commissioning. That scope covers site due diligence and environmental assessment, grid connection applications to the relevant DNSP and AEMO, civil and structural engineering, single-axis tracker procurement and installation, DC collection design, AC substation engineering and the AEMO NEM registration process. Where a project requires a connection agreement with a transmission network service provider, we manage that engagement and the associated technical studies on your behalf.

Single-axis tracking and yield optimisation

Ground-mounted utility-scale projects almost universally benefit from single-axis horizontal tracking, which lifts annual yield by 20–30% relative to fixed-tilt arrays at most Australian latitudes and terrain types. Zenith specifies and installs tracker systems from proven tier-1 manufacturers, with the tracker algorithm selected and tuned to the specific terrain, wind loading zone and soiling environment of each site. We model backtracking schedules, row pitch and inter-row shading at hourly resolution across a typical meteorological year, and we validate those models post-commissioning against actual generation data so every project informs the next.

What Zenith delivers on a utility project

• Land assessment, title review and suitability report for development
• Grid connection application, load flow studies and protection coordination with the DNSP and NSP
• Full civil engineering: access roads, drainage, piling and cable trenching
• Single-axis tracker installation and commissioning with terrain-adaptive backtracking
• DC collection, combiner boxes and string monitoring to panel-string resolution
• AC substation design and construction, including MV/HV switchgear
• AEMO NEM registration, metering installation and market participant setup

PPAs, offtake and project finance

A utility farm is only as bankable as its offtake. Zenith works with a network of corporate offtakers, energy retailers and project finance advisors to structure power purchase agreements that satisfy lender requirements and deliver the long-term revenue certainty developers and landowners need. Corporate PPAs are an increasingly common financing vehicle in 2026, with large industrial and retail groups actively seeking contracted renewable generation to meet scope-two reduction commitments. We can introduce your project into those conversations and provide the technical due-diligence materials lenders and offtakers require.

Construction is managed under a fixed-price EPC contract with liquidated damages provisions for schedule and performance, so your development budget and financial model remain intact. Our procurement relationships with tier-1 panel and tracker manufacturers, built across multiple gigawatts of installed capacity, give us supply certainty and pricing that smaller contractors cannot match. From the first feasibility conversation to the moment your farm dispatches its first megawatt-hour into the NEM, you have one team, one contract and one performance obligation.
