What Sunlock does

Sunlock is an Australian designer, manufacturer, and distributor of commercial-scale solar mounting systems headquartered in Clayton South, Victoria. Founded in 2013, the company serves commercial solar installers, EPC contractors, and commercial and industrial building owners across Australia and New Zealand. Its core technology is a proprietary C-Channel rail platform built from 6000 series aluminium, 304 stainless steel, and Zinc Aluminum Magnesium (ZAM) coated steel, with a 25+ year service life validated by independent corrosion consultants CMET Pty Ltd. The product portfolio centres on multiple rooftop mounting configurations — Flush, East West Fixed Tilt, North Fixed Tilt, and Adjustable A-Frame — and extends into TRAYLOCK cable management, GROUNDLOCK groundmount systems (engineered up to Wind Region D, 79.2 m/s), a waterproof Commercial Solar Carpark, and specialised clamps such as the Bulb Clamp for KingZip Standing Seam roofs.

Sunlock's business model is built on one-time hardware sales through a sales-led, project-based go-to-market. Pricing is quote-based with no public list, and the company bundles site-specific engineering certification (per AS/NZS 1170.2:2021), structural assessments, rooftop inspections, pull-up testing, and post-installation torque verification into the engagement process, offering the initial site-specific certification free of charge as a demand-generation lever. Distribution is direct to commercial installers and project developers, with no e-commerce channel. Named customers span government (ANSTO, Town of Port Hedland), energy/utilities (CleanPeak Energy, RACV Solar, Autonomous Energy/Iberdrola Australia), retail and logistics (Metcash, Amazon, Sunnybank Hills Shoppingtown, Fountain Gate Shopping Centre), and sports facilities (Curlewis Golf Club), with anchor projects including a 4.83MW rooftop installation at the Tonsley Innovation Precinct and a 1.6MWp installation at the ANSTO Australian Synchrotron.

Revenue model

1. Commercial Solar Mounting Systems: Sunlock generates revenue through the sale of commercial solar mounting hardware and systems. This includes rooftop mounting systems (flush, tilt, A-frame), groundmount systems (GROUNDLOCK), cable management (TRAYLOCK), solar carpark structures, and proprietary channel/rail components. Revenue is primarily one-time hardware sales with associated engineering certification services bundled in.
2. Engineering Services: Site-specific engineering certificates, building structural certificates, rooftop inspections, pull-up testing, post-installation inspections and torque testing, and pallet loading engineering assessments are offered as fee-bearing services bundled with commercial projects.
